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.
Use Buttermilk In:
- Buttermilk Pancakes
- Buttermilk Cornbread
- Buttermilk Biscuits
- Skillet Cornbread
- Ranch Dressing
- Homemade Pancake Syrup
- Cinnamon Roll Biscuits
- Hershey's Chocolate Cake
- Cannoli Cake
- Lemon Blueberry Pancakes
- English Muffins

Buttermilk Substitute
Equipment
Ingredients
- 1 Tablespoon white vinegar, (or lemon juice) (15 ml)

Instructions
- Pour the tablespoon of vinegar into a 1 cup measurer. Fill the rest of the 1 cup measurer with milk.
- Gently stir and let the mixture sit for about 5 minutes. This will allow the milk to slightly curdle, giving it a buttermilk-like texture and taste.

Our Buttermilk Substitute hack saves me time and time again.


This recipe worked just like store-bought buttermilk.
Could whey be used instead of vinegar to make buttermilk?
I just love to drink buttermilk. I am always picking up a quart when wife isn’t looking. It never lasts for more than a few hours. My Dad loved it too. My brother can’t stand it at all. He even tried to like it to be like my dad but failed. I wish there was a way to get the butter chunks in. By the way, if you get a really sore throat, try drinking lots of cold buttermilk and your sore throat will be finished.
I need to make 500mls do I use 2 cups almond milk and 2 teaspoons white vinegar?
If making just 1/2 cup of buttermilk, do I half both ingredients or just the milk?
Yes, half both.
I tried this with coconut milk and it didn’t curdle at all.
That’s not milk 🤦🏾♂️
this literally saved my life . THANK U.
I’m almost a 70 year old male. Never baked before. I’m trying different recipes to replicate my mam’s baking when I was a teenager. The buttermilk substitute is a god send. Thank you. John.
After I make it how long does it last in the refrigerator?
1-2 weeks depending on the freshness of your ingredients.
Can I substitute milk for almond milk?
yes, that should work!
very pleased to have found your buttermilk recipe. shop-bought cartoons just contain too much quantity for my use.
thank you!
I have been using your suggestions for making buttermilk. Thank you for saving me. I never have buttermilk when I need it.
