Skip the trip to the store and learn How to Make Buttermilk substitute at home with simple pantry ingredients, including dairy-free and vegan options!

I love learning simple how-to swaps for my kitchen, like how to make your own Vanilla Extract, How to Ripen Bananas, or make some Playdough for the kids.

An easy buttermilk alternative being poured from a liquid measuring cup to a white bowl to use in a recipe.

Our Buttermilk Substitute hack saves me time and time again.

We've all been there–you're several ingredients deep in a recipe and realize it calls for buttermilk, which you don't have. Instead of making a trip to the store, just make your own buttermilk substitute! It's easy, inexpensive, and I'm sure you already have everything you need.

Buttermilk Substitute:

Any of these options will work great in a recipe, just pick the best one for you based on what you have in your pantry and fridge. 

  • 1 cup buttermilk = 1 Tablespoon white vinegar + enough milk to measure 1 cup
  • 1 cup buttermilk = 1 Tablespoon lemon juice + enough milk to measure 1 cup
  • 1 cup buttermilk = 1 cup plain yogurt
  • 1 cup buttermilk = 1 and ¾ teaspoon cream of tartar + 1 cup of milk

How to make Buttermilk:

For the vinegar option, simply pour 1 Tablespoon vinegar into a measuring cup for 1 cup, then fill the rest of the cup with milk. Carefully stir the mixture then let it sit for 5 minutes. If you don't have vinegar, check out other easy alternatives above.

Dairy Free & Vegan Substitute:

Instead of dairy milk, use coconut milk or soy milk. Just add 1 Tablespoon vinegar or lemon juice to a 1 cup measuring cup, then fill the rest of the way with coconut or soy milk. Stir and let sit for 5 minutes before using in a recipe.

Buttermilk Freezing Instructions:

Buttermilk freezes great for up to 3 months. You could even pour in an ice cube tray so it's easy to use small amounts as needed.

How do i make buttermilk with the probiotics in it?

Use the yogurt instead of buttermilk. But if your cooking with it expect the probiotics to die off anyways. This is also true with commercial saurkraut its pasteurized leaving little to no bacteria left. Home fermentation all the way.

This might be a no-brainer, but, can I make the buttermilk substitute a few hours ahead so it’s ready when I throw my cornbread together?
Thank you!!

if you need more than 1 cup – do you double up the recipe – 2 tbs for 2 cups?
