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.

Thank you.
A caution…
The taste of the yoghurt substitute might be similar to buttermilk but the consistency will be different. One will end up with a drier batter and drier baked goods.
I’ve tried both lemon juice and vinegar. The lemon juice definitely thickened/curdled the milk more. Lemons are about 10x more acidic. (Even though they are only about 1 digit different on the pH scale, the pH scale is logarithmic, meaning a factor of 10, 2 digits would be a factor of 100, etc)
Thirdly, the lemon juice and vinegar methods will impart different flavours to the end product, …different from buttermilk and different from each other.
