Quick & Easy Buttermilk Substitute
Have you ever been in the middle of prepping what will be a beautiful batch of waffles or pancakes and BAM–you realize you need buttermilk?! I don’t know about you, but I don’t keep a bottle in my fridge at all times, so when this happens, I’m left with two options: get in the car and drive to the store, or just make this easy buttermilk substitute. The choice is really an no-brainer.
While real, cultured buttermilk is honestly better than any substitute and will always yield the best taste, texture and flavor, when you’re in a pinch a substitute is better than nothing at all (and better than just regular milk–more on that below!) This “recipe” I’m sharing today is extremely simple and uses ingredients that, unlike the real thing, are almost always already in your kitchen.
What does buttermilk do?
- Imparts a rich, slightly tangy flavor.
- Can be a major factor in creating texture and rise (as you can see in my tall, fluffy banana muffins).
- Adds moisture, much like sour cream.
What You Need
This quick and easy buttermilk substitute is incredibly simple, and my hope is that you have what you need at home already. Here’s what you need:
- Lemon juice OR vinegar. Fresh or bottled lemon juice OR distilled white vinegar will work equally well. Whichever you choose, this ingredient is the acid that will change your milk into buttermilk. Having trouble deciding between the two? Don’t think too much about it–you really won’t taste either ingredient in your end result, so just use whatever you have on hand!
- Milk. If you’ve ever used store-bought buttermilk, then you know it’s pretty thick. To get this quick and easy substitute as close to the consistency of the real thing, I recommend using whole milk or even heavy cream. If all you have on hand is 2% milk, that will work–thinner buttermilk is still better than nothing. And yes, non-dairy milks work just fine too!
SAM’S TIP: While I haven’t tried these myself, here are a few other substitutes that should work well for replacing one cup of buttermilk: 1 cup of plain yogurt; ¾ cup sour cream (or full fat Greek yogurt) + ¼ cup water or milk; 1 ½ teaspoons cream of tartar + 1 cup milk; or buttermilk powder (follow package instructions).
Remember, this is just an overview of the ingredients I used and why. For the full recipe please scroll down to the bottom of the post!
How to Make My Easy Buttermilk Substitute
- Add one tablespoon of either vinegar or lemon juice to a liquid measuring cup.
- Add milk until you reach 1 cup of liquid.
- Stir together. The mixture may curdle; do not stress if this happens–this is a good thing!
- Use as needed.
SAM’S TIP: Many buttermilk substitute recipes suggest you let the milk mixture sit for 5-10 minutes before using. This actually isn’t necessary, because once the milk and acid are combined, the acidification happens instantly! If you still feel better letting the mixture sit, you can just prepare your buttermilk substitute at the beginning of your recipe.
Today’s recipe is for a full cup of buttermilk and can easily be doubled. Here is a breakdown for recipes that require less than a cup of buttermilk:
- ¾ cup buttermilk = 2 ¼ teaspoons lemon juice/vinegar + milk to fill to ¾-cup line
- ⅔ cup buttermilk = 2 teaspoons lemon juice/vinegar + milk to fill to ⅔-cup line
- ½ cup buttermilk = 1 ½ teaspoon lemon juice/vinegar + milk to fill to ½-cup line
- ¼ cup buttermilk = ¾ teaspoon lemon juice/vinegar + milk to fill to ¼ cup line
Frequently Asked Questions
No. Buttermilk is acidic, and any recipe that has been created using it is typically designed to have a specific reaction between the buttermilk (acid) and the leavening agents (usually baking soda). Note: sometimes I do use buttermilk without baking soda, like in my coffee cake and vanilla cake. In these instances it is to enhance the moisture and flavor of the recipe.
Regular milk isn’t acidic, which means the reaction won’t take place. Your baked goods may not rise properly and can turn out drier, less flavorful, and less tender if you use plain milk where buttermilk is called for.
Yes! You can use the ratio mentioned above with non-dairy milks, and you’ll still be left with a fantastic buttermilk substitute! I rarely bake with these milks, but this is a good vegan buttermilk substitute if you need one.
It should hold up about a week in a sealed container in your refrigerator. However, I recommend just making it as needed rather than making it in bulk in advance.
Generally I would not recommend it. While some recipes will fare well with this substitution (I often make my biscuits with buttermilk instead of the whole milk indicated), not all recipes will be as forgiving and it is best to use the type of milk called for.
I know that this isn’t new information to many seasoned bakers, but I’m hoping that it will help someone out in a pinch.

Suhima khatri
Can we used diluted curd as a buttermilk…pls suggest
Sam
Hi Suhima! There are some differences between diluted curd and buttermilk, so I’m not sure how it would work as a buttermilk substitute. It may work in some instances but not in others. It really depends on the recipe and amounts.
mayaen
I have a recipe for 11\4 what measurement should I use
Sam
I’m not really sure what you are asking when you say 11/4? I’m sorry
Patti
Hi Sam, in case recipes asking for buttermilk, can sour cream be used to achieve the same results?
Sam
Hi Patti! It really depends on the recipe and it’s usually not a 1 to 1 substitution. 🙂
Stephanie R
Can I use sourdough discard to make a buttermilk substitution and if so, what would be the process?
Thanks!
Sam
Hi Stephanie! Unfortunately I am not very familiar with using sourdough discard. 🙁
Christine
Thank you for the recipe, will try it
Taylor
Hi 🙂 i was just wondering if it has to be with cow milk because I can’t consume any dairy and i was wondering if i could use almond milk or any other type of milk that is dairy free.
Sugar Spun Run
Hi, Taylor! Yes, you can! Almond milk or soy milk would work fine as a substitute. I rarely bake with these milks, but this substitution will work and will help replicate the taste of traditional buttermilk in your recipe. 🙂
Kathy
They make a powdered form of buttermilk. Is it any good?
Sam
Hi Kathy! I honestly have never used it so I’m not sure.
Crystal
I plan to make this for a recipe that only calls for a 1/2 cup of buttermilk, do I only use a 1/2 cup of this after its made?
Sam
Hi Crystal! You can cut the recipe in half if you’d like. Just use half a tablespoon of lemon juice and add milk to the half cup line with milk. 🙂
Laura
I only have 1% milk, would this still work?
Alternatively I also have half and half in the house, would that work better?
Thank you
Sugar Spun Run
Hi, Laura! Others have used 1% milk with success, but the fat from the half and half would be better suited in most recipes. 🙂
Yode
This looks easy! Thank you. Can you use evaporated milk instead of whole milk?
Sugar Spun Run
Thank you, Yode! It will depend on the recipe that you are using the buttermilk for. It is best made using whole milk. 🙂
Barbara Johanntges
I only use skim milk how do I adjust to make buttermilk. I also have heavy cream. Should I dilute heavy cream with skim milk then add lemon/ vinegar? How much skim and how much heavy crime to dilute properly?
Sam
Hi Barbara! You would use the same measurements here. You can do it with the skim milk and it will still react the way it is supposed to, but using the skim milk does lower the fat content and you will lose some of the moisture in your baked goods.
Marisa
Hello thank you for this easy and lovely recipe.
I just wanted to check, will I be able to use full cream milk instead of whole milk?
Thanks you.
Sam
I haven’t tried it but I think that should be fine 🙂
Marisa
Hello Sam thank you.
sb
hi what can i substitute for unsalted butter? coconut oil maybe?
looking for something nondairy.
btw your recipes look amazing!
Sugar Spun Run
Thank you so much! As far as a butter substitute, that is really dependant on the recipe itself and what will work best. 🙂
Nadine E. Spelman
If I make buttermilk from milk and lemon juice or vinegar does the milk have to be whole milk? I only use 1% milk and worry it won’t be a good substitute. I al ssd o would like to know if using lemon juice does it give the “buttermilk” a lemony taste? The same question if I use vinegar…?
Thanks for any answer.
Sugar Spun Run
Hi, Nadine! I recommend using whole milk with this recipe. When you add either lemon or vinegar you will not be able to taste either. 🙂
Blair
Thanks, again for ANOTHER great recipe! I used this recipe with 2% milk to go into your buttermilk pancakes. It was super easy to make!
Sugar Spun Run
I am so glad that it worked perfectly and you enjoyed your pancakes, Blair! 🙂
