1. What Is Buttermilk?
Buttermilk is a tangy dairy ingredient commonly used in American baking and cooking. It adds acidity, moisture, and a slightly sour flavor to recipes such as pancakes, biscuits, cakes, and fried chicken.
Traditional buttermilk was originally the liquid left behind after churning cultured cream into butter. Today, most grocery-store buttermilk is cultured milk made with selected lactic acid bacteria.
A homemade substitute made with milk and lemon juice or vinegar is different. It doesn’t undergo fermentation, but it can provide enough acidity for many recipes.
Different Types of Buttermilk
| Type | How It’s Made | Common Uses |
|---|---|---|
| Traditional buttermilk | Liquid remaining after butter churning | Traditional cooking |
| Cultured buttermilk | Milk fermented with bacterial cultures | Biscuits, cakes, dressings |
| Homemade substitute | Milk mixed with lemon juice or vinegar | Pancakes, muffins, quick breads |
| Yogurt substitute | Plain yogurt diluted with milk or water | Cakes and pancakes |
| Dairy-free substitute | Plant-based milk mixed with acid | Vegan baking |
Why Is Buttermilk Important in Baking?
Buttermilk helps improve the flavor and texture of many baked goods. Its acidity reacts with baking soda to produce carbon dioxide, which helps batter rise.
It can also influence gluten development, helping certain baked goods stay tender. Its mild tang balances sweetness and complements ingredients such as chocolate, vanilla, and fruit.
2. Ingredients You Need to Make Buttermilk
One of the best things about homemade buttermilk is its simplicity. You don’t need special equipment, expensive ingredients, or complicated techniques.
The basic recipe requires only milk and an acidic ingredient. Whole milk provides a richer result, but 2% or skim milk also works. Lemon juice adds mild citrus notes, while white vinegar offers a more neutral flavor.
Homemade Buttermilk Ingredients
Yield: 1 cup
- 1 tablespoon fresh lemon juice or distilled white vinegar
- Enough milk to make 1 cup total
Optional Ingredient Alternatives
- Whole milk: Richer flavor and texture.
- 2% milk: A convenient everyday choice.
- Skim milk: A lower-fat option.
- Lemon juice: Provides acidity with a mild citrus note.
- White vinegar: Provides acidity with little added flavor after baking.
- Apple cider vinegar: Works in many recipes but has a slightly different taste.
- Plain yogurt: Useful when a thicker substitute is needed.
- Unsweetened soy milk: Suitable for many dairy-free baking recipes.
Equipment You’ll Need

Helpful tip: Use a liquid measuring cup with clear measurement markings. This makes it easier to prepare the exact amount required by your recipe.
3. How to Make Buttermilk Step by Step
Making a homemade buttermilk substitute takes only a few minutes of active preparation. The method is simple enough for beginners and requires no heating or cooking.
The most important step is measuring the finished liquid correctly. Adding a full cup of milk plus a tablespoon of acid creates slightly more than one cup, which can affect recipes that require precise measurements.
Step 1: Measure the Acid
Add 1 tablespoon of fresh lemon juice or distilled white vinegar to a liquid measuring cup.
Either ingredient works for the basic method.
Step 2: Add the Milk
Pour milk into the measuring cup until the total mixture reaches the 1-cup line.
Use whole milk for a richer result or 2% milk for an everyday substitute.
Step 3: Stir the Mixture
Use a spoon or small whisk to stir the milk and acid gently.
Make sure the acid is evenly distributed throughout the liquid.
Step 4: Let It Rest
Allow the mixture to sit for 5–10 minutes.
During this time, the milk may develop small curds or appear slightly separated. This is normal.
Step 5: Stir Again
Give the mixture another gentle stir before using it.
Don’t worry if it looks thinner than store-bought buttermilk. Acidified milk doesn’t develop the same thick texture as cultured buttermilk.
Step 6: Use in Your Recipe
Add the homemade substitute to your pancake batter, biscuit dough, muffin mixture, or cake recipe.
Use the amount specified in the original recipe.
Step 7: Refrigerate Any Leftovers
If you have extra substitute, transfer it to a clean, covered container and refrigerate promptly.
For the best quality, use it within 24 hours.
Best result: Prepare homemade buttermilk just before you need it. Freshly mixed acidified milk is convenient and helps avoid unnecessary storage.
4. How to Make Buttermilk With Lemon Juice
Lemon juice is one of the easiest ingredients for making homemade buttermilk substitute. Its natural acidity works well in many baking recipes, especially pancakes, muffins, cakes, and quick breads.
Fresh lemon juice is a great option when you have lemons available. Bottled lemon juice can also work, provided it doesn’t contain added sweeteners or unusual flavorings.
Ingredients
- 1 tablespoon lemon juice
- Milk to make 1 cup total
Instructions
- Pour lemon juice into a measuring cup.
- Add enough milk to reach the 1-cup mark.
- Stir gently until combined.
- Let the mixture rest for 5–10 minutes.
- Stir again before using.
- Add it to your recipe as directed.
Can You Use Bottled Lemon Juice?
Yes. Plain bottled lemon juice can work as a substitute for fresh lemon juice.
The acidity helps create a useful alternative to cultured buttermilk. However, fresh and bottled lemon juice may differ slightly in flavor.
Best for: Pancakes, waffles, cakes, muffins, and sweet quick breads.
5. How to Make Buttermilk With Vinegar
If you don’t have lemons, white vinegar is another excellent option. It’s inexpensive, easy to measure, and commonly available in home kitchens.
Distilled white vinegar is generally preferred because its flavor is relatively neutral. Once mixed into batter and baked, the vinegar taste is usually not noticeable.
Ingredients
- 1 tablespoon distilled white vinegar
- Milk to make 1 cup total
Instructions
- Add the vinegar to a liquid measuring cup.
- Pour in milk until the total volume reaches 1 cup.
- Stir gently with a spoon.
- Let the mixture stand for 5–10 minutes.
- Stir again before adding it to your recipe.
- Use immediately for the best results.
Lemon Juice vs. White Vinegar
| Feature | Lemon Juice | White Vinegar |
|---|---|---|
| Flavor | Mild citrus | More neutral |
| Preparation time | 5–10 minutes | 5–10 minutes |
| Acidity | Acidic | Acidic |
| Best uses | Cakes and muffins | Biscuits and pancakes |
| Availability | Fresh or bottled | Pantry staple |
| Measurement | 1 tbsp per finished cup | 1 tbsp per finished cup |
Both ingredients work well in many everyday baking recipes. Choose whichever is available.
6. How to Make Buttermilk Without Lemon Juice or Vinegar
You can still prepare a useful buttermilk substitute without lemon juice or vinegar. Plain yogurt, sour cream, and kefir are good alternatives because they already have a tangy flavor.
These ingredients are usually thicker than cultured buttermilk, so some need to be diluted with water or milk. The goal is a smooth, pourable mixture that blends easily into batter.
Best Alternatives
- Plain yogurt: Dilute with milk or water.
- Greek yogurt: Add more liquid to reduce thickness.
- Sour cream: Whisk with milk until pourable.
- Plain kefir: Often works as a direct substitute.
- Dairy-free yogurt: Choose an unsweetened variety.
- Cultured buttermilk: Use directly when available.
How to Make Buttermilk With Yogurt
Combine:
- ¾ cup plain yogurt
- ¼ cup milk or water
Whisk until smooth. Adjust the liquid slightly if the mixture is too thick.
How to Make Buttermilk With Sour Cream
Combine:
- ¾ cup sour cream
- ¼ cup milk or water
Stir until the mixture becomes smooth and pourable.
Helpful tip: Yogurt and sour cream substitutes are particularly useful for pancakes, muffins, and quick breads.
7. How to Make Dairy-Free Buttermilk
Dairy-free buttermilk substitute is a convenient option for vegan baking or people avoiding dairy. Unsweetened plant-based milk can replace cow’s milk in the basic two-ingredient method.
Soy milk is often a good choice because its protein content helps it respond to added acid. Oat milk and almond milk can also work, although they may not thicken noticeably.
Dairy-Free Buttermilk Ingredients
- 1 tablespoon lemon juice or white vinegar
- Unsweetened plant-based milk to make 1 cup total
Instructions
- Choose unsweetened soy, oat, or almond milk.
- Add lemon juice or vinegar to a measuring cup.
- Pour in plant milk until the mixture reaches 1 cup.
- Stir gently.
- Let stand for 5–10 minutes.
- Stir again before using.
- Add to your baking recipe.
Best Plant-Based Milk Options
| Plant Milk | Texture | Best Uses |
|---|---|---|
| Soy milk | Often thickens slightly | Cakes and pancakes |
| Oat milk | Smooth and creamy | Waffles and muffins |
| Almond milk | Usually thinner | Pancakes and quick breads |
| Cashew milk | Mild and smooth | Cakes |
| Coconut milk beverage | Slight coconut flavor | Sweet baked goods |
For dairy allergies, always check labels for possible cross-contact. For nut allergies, avoid almond and cashew milk.
8. Homemade Buttermilk Measurement Chart
Knowing the correct measurements makes homemade buttermilk easy to prepare in any quantity. You don’t need to make a full cup when your recipe requires only a few tablespoons.
The basic ratio is 1 tablespoon of lemon juice or vinegar per cup of finished mixture. Scale the acid and milk proportionally.
Buttermilk Conversion Table
| Buttermilk Needed | Lemon Juice or Vinegar | Milk |
|---|---|---|
| ¼ cup | ¾ teaspoon | Add to reach ¼ cup total |
| ⅓ cup | 1 teaspoon | Add to reach ⅓ cup total |
| ½ cup | 1½ teaspoons | Add to reach ½ cup total |
| ¾ cup | 2¼ teaspoons | Add to reach ¾ cup total |
| 1 cup | 1 tablespoon | Add to reach 1 cup total |
| 1½ cups | 1½ tablespoons | Add to reach 1½ cups total |
| 2 cups | 2 tablespoons | Add to reach 2 cups total |
| 3 cups | 3 tablespoons | Add to reach 3 cups total |
| 4 cups | 4 tablespoons | Add to reach 4 cups total |
How to Make ½ Cup of Buttermilk
Add 1½ teaspoons lemon juice or vinegar to a measuring cup.
Pour in enough milk to reach ½ cup. Stir and let stand for 5–10 minutes.
How to Make 2 Cups of Buttermilk
Add 2 tablespoons lemon juice or vinegar to a measuring cup.
Fill with milk until the total volume reaches 2 cups. Stir and let rest before using.
Important Measurement Tip
Always add the acid first, then pour in enough milk to reach the desired final volume.
This helps prevent adding more liquid than the recipe requires.
9. Best Recipes That Use Buttermilk
Buttermilk is useful in both sweet and savory cooking. Its tangy flavor complements rich ingredients, while its acidity supports the texture of many baked goods.
The homemade substitute works particularly well in recipes that need acidity but don’t depend heavily on the thickness of cultured buttermilk.
Popular Buttermilk Recipes
| Recipe | Why Buttermilk Helps |
|---|---|
| Buttermilk pancakes | Helps create a tender texture |
| Buttermilk biscuits | Adds tanginess and moisture |
| Buttermilk waffles | Supports a soft interior |
| Chocolate cake | Adds moisture and acidity |
| Vanilla cake | Helps create a tender crumb |
| Red velvet cake | Contributes traditional tang |
| Blueberry muffins | Adds moisture |
| Banana bread | Works with baking soda |
| Cornbread | Adds tangy flavor |
| Fried chicken | Used in flavorful marinades |
| Ranch dressing | Creates a creamy, tangy base |
| Quick breads | Supports flavor and texture |
Why Buttermilk Makes Pancakes Fluffy
Buttermilk contains acid that reacts with baking soda. This reaction produces carbon dioxide bubbles that help the batter expand.
Other ingredients also matter. Baking powder, eggs, flour, and the mixing technique all affect the finished pancakes.
Avoid overmixing the batter. A few small lumps are usually fine and can help prevent tough pancakes.
10. Homemade Buttermilk for Fried Chicken
Buttermilk is a popular ingredient in Southern-style fried chicken because it adds tangy flavor and moisture to marinades.
Commercial cultured buttermilk is often preferred because its thicker texture coats chicken well. A homemade milk-and-vinegar substitute can work in some marinades, but it will generally be thinner.
Simple Buttermilk Chicken Marinade
Ingredients:
- 1 cup cultured buttermilk or homemade substitute
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon paprika
- ½ teaspoon garlic powder
- 1 pound chicken
Instructions
- Combine the buttermilk and seasonings.
- Place chicken in a food-safe container.
- Pour the marinade over the chicken.
- Cover and refrigerate.
- Marinate for several hours or according to your recipe.
- Remove the chicken from the marinade.
- Discard used marinade unless it will be thoroughly boiled.
- Cook chicken to an internal temperature of 165°F (74°C).
Important Food Safety Tips
- Always marinate chicken in the refrigerator.
- Never leave raw chicken at room temperature while marinating.
- Keep raw poultry separate from ready-to-eat foods.
- Wash utensils and surfaces after handling raw chicken.
- Use a food thermometer to check doneness.
- Don’t reuse raw chicken marinade as a cold sauce.
11. Common Mistakes When Making Buttermilk
Although homemade buttermilk is easy to prepare, small mistakes can affect baking results. Incorrect measurements, excessive acid, and using unsuitable milk are common problems.
Another mistake is expecting homemade acidified milk to become as thick as cultured buttermilk. The two ingredients are produced differently, so their textures won’t be identical.
Homemade Buttermilk Troubleshooting Guide
| Problem | Likely Cause | Best Solution |
|---|---|---|
| Milk doesn’t thicken | Normal for some milk types | Use if properly measured |
| Strong vinegar flavor | Too much vinegar | Measure accurately |
| Mixture is too thin | Acidified milk is naturally thinner | Try diluted yogurt |
| Cake is dense | Leavening or mixing issue | Check baking soda and mixing |
| Pancakes taste sour | Excess acid | Follow the correct ratio |
| Mixture separates | Natural acid reaction | Stir before using |
| Batter is too thick | Substitute too thick | Adjust with a little liquid |
| Milk smells spoiled | Dairy may be unsafe | Discard it |
| Recipe doesn’t rise | Leavening imbalance | Follow a tested recipe |
Why Isn’t My Homemade Buttermilk Curdling?
Not all milk develops obvious curds when mixed with lemon juice or vinegar.
The result depends on the type of milk, temperature, and acidity. Slight separation is common, but visible curdling isn’t necessary for many baking recipes.
Important: Don’t keep adding vinegar simply because the mixture hasn’t thickened.
Can You Use Cold Milk?
Yes. Cold milk from the refrigerator works well.
You don’t need to warm it before adding lemon juice or vinegar. Mix the ingredients, allow a short resting period, and use the substitute as directed.
12. How to Store Homemade Buttermilk
Homemade acidified milk should be treated as a perishable dairy product. Lemon juice and vinegar add acidity, but they don’t make milk shelf-stable.
For the best quality, prepare only the amount needed and use it promptly. Refrigerate any extra mixture immediately in a clean, covered container.
Buttermilk Storage Guide
| Storage Method | Recommendation |
|---|---|
| Room temperature | Don’t leave out longer than 2 hours |
| Refrigerator | Keep at 40°F or below |
| Best quality | Use within 24 hours |
| Freezer | Possible, but texture may change |
| Container | Clean and airtight |
| Before using | Stir gently |
Can You Make Buttermilk the Night Before?
Yes. Prepare the substitute, cover it, and refrigerate immediately.
Stir again before adding it to your recipe. For the best quality, use within 24 hours.
Can You Freeze Homemade Buttermilk?
You can freeze acidified milk, but separation may occur after thawing.
Thaw it in the refrigerator and stir before using. Because the texture may change, freshly prepared substitute is usually preferable for baking.
How Do You Know If Buttermilk Has Gone Bad?
Discard milk products that show mold, unusual discoloration, or an unexpected rotten odor.
Also discard dairy that has been stored improperly, even if it looks normal.
Never use spoiled milk to make a buttermilk substitute.
13. Homemade Buttermilk vs. Store-Bought Buttermilk
Homemade buttermilk substitute and commercial cultured buttermilk aren’t exactly the same. Their biggest differences involve how they’re made, their thickness, and their flavor.
Cultured buttermilk develops acidity through bacterial fermentation. Homemade acidified milk gets its acidity from added lemon juice or vinegar.
Comparison Table
| Feature | Homemade Substitute | Cultured Buttermilk |
|---|---|---|
| Preparation | Milk and acid | Bacterial fermentation |
| Time | 5–10 minutes | Ready to use |
| Texture | Usually thin | Usually thicker |
| Flavor | Mildly tangy | Distinct fermented tang |
| Cost | Uses common ingredients | Requires separate purchase |
| Pancakes | Works well | Excellent |
| Biscuits | Often suitable | Traditional choice |
| Marinades | Thinner coating | Usually better coating |
| Dressings | Less creamy | Creamier texture |
When Should You Use Homemade Buttermilk?
Use homemade acidified milk when you need a quick substitute for pancakes, waffles, muffins, cakes, or quick breads.
It’s especially convenient when a recipe requires only a small amount.
When Is Cultured Buttermilk Better?
Choose cultured buttermilk for recipes where thickness and fermented flavor are especially important.
Examples include traditional biscuits, creamy dressings, and certain marinades.
14. How to Make Buttermilk for Different Diets
Homemade buttermilk substitute can be adapted for different dietary preferences. Changing the milk type allows you to prepare lower-fat, lactose-free, or dairy-free alternatives.
However, different ingredients may affect the texture and flavor of baked goods. Choose substitutions that suit your recipe rather than assuming every milk behaves identically.

- Gluten-free: The substitute is generally gluten-free when ingredients are appropriate, but check labels.
- Higher-fat: Use whole milk for a richer result.
Can You Make Buttermilk With Lactose-Free Milk?
Yes. Lactose-free dairy milk can be mixed with lemon juice or vinegar using the same basic method.
The mixture may behave slightly differently from regular milk, but it can work in many baking recipes.
Is Homemade Buttermilk Healthy?
The nutritional value depends mainly on the milk used.
Milk provides protein, calcium, and other nutrients. The small amount of lemon juice or vinegar contributes little to the overall calorie content.
Choose a milk type that fits your dietary needs and preferences.
15. Best Tips for Perfect Homemade Buttermilk
Making homemade buttermilk successfully comes down to accurate measurements and choosing the right ingredients. You don’t need special skills, but following a few simple tips can improve consistency.
