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.

Could whey be used instead of vinegar to make buttermilk?

To make buttermilk, the milk should be slightly warm like bofy temperature.

Made this dozens of times with great results. Oddly enough this time it failed to cuddle the milk in any way. It’s like the lemon juice is staying separate from the whole milk. Any idea why it failed? Even letting it sit overnight; then, in desperation, adding more lemon juice didn’t work. It was fresh milk and I always measure instead of eyeballing. Any way of still fixing this, like mixing some sour cream or heavy cream?

I didn’t have enough buttermilk on hand so I used this recipe to make more buttermilk. This worked out great! Look just like carton buttermilk.

I’ve used this recipe before and it turned out to be good buttermilk. Tonight I used whole milk and lemon juice but it never became anything but lemon flavored milk! I started over using whole milk and white vinegar. Again, it never became buttermilk. The whole milk was new. What could have caused my problem?
