Tips and Notes

Why use buttermilk when making chocolate cake?

Buttermilk is a wonderful choice for baking, especially in cakes. It lends a rich depth of flavor, and also creates a soft and fluffy texture. This happens because of a chemical reaction between the acid in the buttermilk and the gluten in the flour. Bottom line: if you like a soft cake with exceptional flavor, choose buttermilk! And if you don’t have any buttermilk on hand, it’s super easy to make with ingredients that you likely already do have!

What if I don’t have buttermilk on hand?

Homemade buttermilk is really simple and quick to make if you don’t have any. All you need is plain white vinegar and regular milk, preferably whole or 2%. Simply add 1 Tablespoon of white vinegar to a liquid measuring cup and add enough milk to reach the 1 cup line. Stir, then allow the mixture to sit undisturbed for 5 minutes before adding to your recipe. That makes 1 cup of buttermilk, which is how much you need for this recipe.
