Ingredients 

This small-batch frosting recipe is made with simple ingredients. Find the amounts in the printable recipe card at the bottom of this post. Here is a rundown of what you will need.

  • Butter softened to room temperature. This can be salted or unsalted butter. If using salted butter, you can omit the pinch of salt or leave it in. I prefer the extra salt, and I don’t omit it.  This must be soft enough for a finger to leave an indent when pressed but not melted or greasy.
  • Powdered sugar/ confectioner’s sugar
  • Unsweetened cocoa powder – This can be natural cocoa powder or Dutch-processed. Dutch-processed cocoa will give a deeper chocolate flavor and a darker color.
  • Milk, heavy cream, or buttermilk at room temperature. The tang of buttermilk or something similarly acidic can help cut the sweetness of the frosting a bit.
  • Half a teaspoon vanilla extract or paste
  • A pinch of salt
  • Optional – Add a little instant espresso powder for extra deep flavor.

Method

If the buttercream is too thick, add a small amount of milk, but take care when adding extra liquid. If you add too much, you’ll need extra powdered sugar to thicken it again, which can make the frosting too sweet.

Buttercream FAQs

How can I make my buttercream less sweet?

American buttercream is always very sweet. Adding in a little acid can help cut the sweetness. You can use buttermilk, Greek yogurt, or sour cream instead of milk. Don’t forget the salt, either. Adding a pinch of salt can help balance out the sweetness of the buttercream. 

How long does this chocolate frosting keep?

Buttercream can be stored in an airtight container in the refrigerator for up to one week. It can also be frozen for up to three months.

What can I do if my buttercream is too runny?

If your buttercream is too thin or runny, you can add more powdered sugar, a little bit at a time, until you reach your desired consistency.

Can I use margarine instead of butter in my buttercream?

Yes, you can substitute margarine for butter, but it will affect the taste and texture of your buttercream. Butter provides a richer flavor.

My buttercream split, what can I do?

This can happen when the milk added to the buttercream is too cold, and it causes the emulsion to break. Take a tablespoonful of the curdled mixture and heat it in the microwave for about 5-10 seconds until it melts. Pour this heated mixture back into your main bowl and whisk it in. This should bring it together.
