Out of buttermilk and need it for a recipe? We have you covered with four easy to make substitutes for buttermilk. Tips and tricks on how to make buttermilk with milk plus lemon, vinegar, cream of tartar or sour cream.
Have you ever pulled out a recipe, totally excited, only to discover it calls for buttermilk and you don’t have any? I don’t know about you, but it’s not an ingredient I keep stocked all the time. Also, I hate buying a big container of it when I don’t need that much for a single recipe! So, I’m sharing FOUR ways to make a buttermilk substitute – I bet you have the ingredients for at least one of these options, if not a few!
These DIY buttermilk substitutes will definitely save you a trip to the store and you can use them in any recipe that calls for buttermilk. For all four options, you can have your substitute ready to go in about 10 to 15 minutes!
Buttermilk Substitutes Start with Milk
For all of these buttermilk substitutes, you will need milk. I recommend using 2% or whole milk for the best results. Also, leave it out for about 30 minutes to bring it to room temperature. Room temperature milk will combine better with the other ingredients.
Buttermilk is acidic and so for these easy substitutes, all you are doing is adding an acidic ingredient to the milk which will slightly curdle it and give it a tangy flavor.
All four options make 1 cup of buttermilk substitute. You can adjust the amounts if you need more or less!
Option 1: Milk and Lemon Juice
- Pour one tablespoon of fresh lemon juice into a liquid measuring cup.
- Pour in enough milk so you have one cup (a scant cup of milk).
- Stir to combine and then let it sit for at least 10 minutes. You can leave it as long as two hours if you don’t need it right away (just leave it in the fridge!).
Option 2: Milk and Cream of Tartar
No lemons? No problem! If you look in your pantry you might have a container of cream of tartar which you can use, too! It’s basically an acid in powder form and works really well.
- Pour one cup of milk into a bowl.
- Add the cream of tartar and whisk vigorously until the powder is dissolved and mixed well into the milk.
- Leave the mixture to sit for 15 minutes and then use it right away. You don’t want it sitting too long otherwise you will have some graininess that settles at the bottom from the cream of tartar.
Option 3: Milk and White Vinegar
This option is like the lemon one but you can use white vinegar instead:
- Pour one tablespoon of white vinegar into a liquid measuring cup.
- Pour in milk until you have one cup total of the mixture. Whisk to combine.
- Let it sit for at least 10 minutes before using or you can keep it in the refrigerator for up to two hours (store in refrigerator).
Option 4: Milk and Sour Cream
Have leftover sour cream from taco night? You can use it to make homemade buttermilk! For this option, you will need equal parts sour cream and milk.
- Place the sour cream in a bowl. Add the milk.
- Whisk until the mixture is smooth.
- Let it sit for 10 minutes or up to two hours in the refrigerator before using it.
Can I make a big batch to keep on hand?
For homemade buttermilk, I recommend making enough for what you need. Unlike store-bought, these DIY options don’t keep as long. They are so easy to make (and there are plenty of options) you can easily just make it as you need it! All of the options I’m sharing are for one cup, but you can easily halve or double it if you need more or less for your recipe.
What can I use buttermilk for?
All kinds of things! Pancakes, cakes, cupcakes, muffins, fried chicken – there are many recipes that call for it. You can use it in place of regular milk, too, if you want to give your recipe a tangy flavor.
Can’t I just use regular milk instead of buttermilk?
It really depends on the recipe! For most that call specifically for buttermilk, they won’t turn out the same if you use just plain milk. Buttermilk is a natural tenderizer, so, for example, if you need it for cakes or cupcakes you won’t get the same texture if don’t use it.
This is why I wanted to share these substitutes – they are so easy! I absolutely hate making unplanned grocery trips and these options have saved me on several occasions. I hope you love them, too! Be sure to save them so you have them when you need buttermilk!

Can I substitute almond milk for the regular milk?

I haven’t tried it, but I would think it would work?!
Yvonne Thomas says
My comment is not about the recipe per se, but rather about the preparation of the buttermilk needed for many recipes. I have purchased the powdered buttermilk sold in grocery stores in their baking aisle. It works by adding water to the powder and is perfect for having on hand all the time.
