how to make Classic Vanilla Buttercream

Ingredients:

  • 2 sticks unsalted butter, softened
  • 5-6 cups confectioners sugar
  • 2 teaspoons vanilla extract
  • 1/3 cup milk or cream
  • 1/2 teaspoon salt

Directions:

  1. Begin by creaming the softened butter until it is smooth.
  2. Blend in the vanilla extract.
  3. Add half of the powdered sugar, salt, and most of the milk. Beat at medium speed until the powdered sugar is fully incorporated.
  4. Add the remaining powdered sugar and milk. Mix at medium speed for another 3 to 4 minutes, scraping the sides of the bowl occasionally.
  5. To achieve the smooth texture, slow down the mixer to the very lowest speed for 1 to 2 minutes to eliminate air pockets.
  6. The buttercream should now be very smooth. This recipe makes about 4 ½ cups of frosting, which is enough to frost a two-layer 8 or 9-inch cake.
  7. If you want to make a larger or smaller batch, you can easily double or halve the ingredients.
  8. You can freeze any leftovers in an airtight container for at least three months. Just thaw on the countertop when you want to use it again.
  9. If your buttercream is too thin, simply add more sugar. If it’s too thick, add a bit more milk.

FAQs

1. Can I use margarine instead of butter?
While you can use margarine, the taste and texture will differ. Butter gives a richer flavor.

2. What can I use if I don’t have confectioners sugar?
You can make your own by blending granulated sugar in a blender or food processor until it becomes a fine powder.

3. How do I fix grainy buttercream?
If your buttercream is grainy, it might be due to not mixing the sugar in well enough. Mix it longer at a medium speed until it becomes smooth. If it’s really stubborn, adding a little milk can help too.
