Homemade Buttermilk Recipe
Learn how to make buttermilk from milk two ways! Forget to add it to your shopping list? Just need a small amount? I’ve got you covered with simple methods for homemade buttermilk, using simple ingredients you probably have on hand!
What Is Buttermilk, Anyway?
Buttermilk is fermented milk. It’s thicker and lumpier than milk and has an acidic, tangy smell similar to vinegar.
Common in baking recipes, buttermilk adds a subtle tang to recipes and creates a tender texture in breads and cakes. It also reacts chemically when combined with baking soda, helping make baked goods rise as they bake.
How Do You Turn Milk Into Buttermilk?
Learning how to make buttermilk from milk is a lot easier than you might think! All you need are two simple ingredients and a few minutes of prep time.
Ingredients
- Milk – Use any milk you have on hand including skim milk, whole milk, or two percent milk.
- Acid – I use freshly squeezed lemon juice or white vinegar to ferment the milk.
How to Make Buttermilk with Vinegar
- Add one tablespoon of white vinegar to a liquid measuring cup.
2. Pour one cup of milk into the cup.
3. Whisk to combine.
4. Set the mixture aside for about ten minutes or until the mix begins to curdle.
How to Make Buttermilk with Lemon Juice
- Pour one tablespoon of freshly squeezed lemon juice into a liquid measuring cup.
2. Add one cup of milk.
3. Whisk to combine.
4. Set the mixture aside for ten minutes or until the milk begins to curdle.
Note: Homemade buttermilk does not have a thick, lumpy appearance like store-bought buttermilk. You might not see a whole lot of change in its appearance, but trust me! The process works.
Helpful Measurements
In a perfect world, recipes always call for even measurements. Unfortunately, this isn’t always the case. So, to help make cooking easy, I’m providing my go-to measurements below.
- ¼ cup buttermilk = ¾ teaspoon lemon juice or vinegar + ¼ cup milk
- ⅓ cup buttermilk = 1 teaspoon lemon juice or vinegar + ⅓ cup milk
- ½ cup buttermilk = 1½ teaspoons lemon juice or vinegar + ½ cup milk
- ⅔ cup buttermilk = 2 teaspoons lemon juice or vinegar + ⅔ cup milk
- ¾ cup buttermilk = 2¼ teaspoons lemon or vinegar + ¾ cup milk

Common Questions When Learning How to Make Buttermilk from Milk
Regular milk will cause your baked goods to become dense and watery, and they won’t have the tangy taste we want with buttermilk.
Yes! Stored in an airtight container, you can freeze buttermilk for up to three months. I like to pour it into ice cube trays and freeze it before transferring it to a sealable bag. Then, you have easy-to-use portions ready to thaw and use!
One isn’t better than the other! Both methods work great.
Buttermilk is a common ingredient used in a variety of recipes such as waffles, pancakes, biscuits, gluten free banana bread, chicken breading, dressings, marinades, slaw, and desserts like red velvet cake mix cookies!
