    Next time you’re out of buttermilk, no need to drop everything and run to the store. You can easily make it at home with just 2 ingredients. And trust me, you won’t believe how simple it is!

    Buttermilk seems intimidating to make yourself, but it’s not at all. You only need milk and vinegar to make it and it’s ready in just 10 minutes. So quick and easy!

    The taste of buttermilk is sour, so I wouldn’t recommend drinking it (although you can if you want). It’s perfect for baking and keeps your baked goods super soft and moist. It’s also great to use in condiments like dressings or syrup. I love using it when making drop biscuits, buttermilk pancakes, or a homemade ranch dressing.

    What is buttermilk?

    If you find yourself asking, “what exactly is buttermilk?” – the answer is simple! Buttermilk is a dairy product made with 2 simple ingredients: milk and vinegar. It’s taste is sour and it usually has a thicker texture than regular milk, but is lower in fat. It’s often used as a leavening agent in baking and helps to lighten, soften and add moisture to baked goods.

    What does buttermilk do in baking?

    It’s all about the texture! The acidity in the buttermilk helps to tenderize baked goods, keeping them super moist and soft. It will also keep your baked goods from browning too fast because of how it changes the pH.

    Variations

    My favorite ratio to use when making buttermilk is 1 cup of whole milk + 1 Tablespoon distilled white vinegar. However there are a few other ways to buttermilk, so feel free to use any of the substitutions below.

    • Use equal parts lemon juice (freshly squeezed) in place of vinegar.
    • Other types of vinegar with neutral flavors will also work (such as apple cider vinegar).
    • Both whole milk or 2% milk work great when making this recipe.
    • Instead of vinegar or lemon juice, you may also use 1 and 3/4 teaspoon cream of tartar with 1 cup milk.

    What is buttermilk used for?

    Buttermilk can be used so many different ways! Use it to add the perfect texture to classic breakfast staples like homemade biscuits, blueberry pancakes or even make a buttermilk syrup to drizzle on top. When baking, mix it into the batter for a super moist and tender blueberry buttermilk cake or Irish soda bread. It also tastes amazing in savory recipes like my creamy cilantro lime dressing or as a coating for crispy baked chicken tenders. The options are endless!

    Storing + freezing

    • To store: Buttermilk can be stored in the fridge for up to 1 week until ready to use. To store, place in the fridge in a covered container. Make sure to give it a stir before using.
