So you're in a middle of a big baking project and suddenly realize you're fresh out of buttermilk! You'll need that acidic effect and flavor that buttermilk provides, so you can't just skip it. "What can I substitute for buttermilk?" you may ask.

Well, here are 5 easy ways to replicate buttermilk's effect and flavor in recipes. With five options, chances are you may have at least some of these ingredients in your pantry and fridge. With luck, you'll have a little regular milk in your fridge. To make a vegan buttermilk substitute, replace the dairy milk in these recipes with almond milk or soy milk.

How to substitute buttermilk

Each buttermilk substitute recipe below combines regular milk with an acidic ingredient like lemon juice or yogurt. Each substitute makes 1 cup.

Substitute 1: White vinegar

1 tablespoon white vinegar + enough milk to make 1 cup

Substitute 2: Lemon juice

1 tablespoon lemon juice + enough milk to make 1 cup

Substitute 3: Cream of tartar

1 ¾ teaspoon cream of tartar + 1 cup milk

Substitute 4: Yogurt

¾ cup yogurt + ¼ cup milk

Substitute 5: Sour Cream

¾ cup sour cream + ¼ cup milk

To make each of these substitutes for buttermilk, stir the ingredients together and let them sit for about 10 minutes so the milk can "sour." Then go ahead, use it as a substitute for buttermilk in baking. One cup of real or substitute buttermilk = one cup of whole, skim, or non-fat milk.
