Why we love this frosting recipe

Easy – You won’t believe how easy this is to make. The only cooking involved is melting the butter in the microwave or stove. Everything can be mixed by hand, so no mixer required.

Versatile – This chocolate icing can be used for more than just brownies. Try it on cakes, cookies, and more.

Delicious – If you are a chocolate lover, this recipe is for you. Creamy, chocolatey, and so good.

Ingredients needed

  • Butter – Unsalted butter works well for this recipe.
  • Cocoa powder – Regular unsweetened cocoa powder is used to make this recipe. I used Hershey’s cocoa powder.
  • Powdered sugar – Powdered sugar, sometimes called confectioners sugar, is used to add sweetness to the frosting.
  • Milk – You can use your favorite milk. Whole milk or cream will give you a richer flavor but 2% will also work.
  • Vanilla extract – This adds another layer of sweetness.

Recipe tips

  • This recipe makes enough to cover a 9×9-inch pan of brownies. You can easily double the recipe if you need more frosting.
  • Want to thin out the frosting? Add a little extra milk until you reach your desired consistency. You can thicken the frosting by adding a little extra powdered sugar.
  • It’s important to make sure the brownies have cooled before spreading the frosting. If they are still warm the frosting will melt and not stay on the brownie.
  • Make sure to wait about 10 minutes after frosting before cutting the brownies. This allows the brownie frosting to harden a little.

How to store leftovers

Store: You can store frosted brownies in an airtight container at room temperature or in the refrigerator to last longer. The icing can also be stored separately in an airtight container. When you are ready to use the icing, microwave for 10 seconds and stir to make it easier to spread.

Freeze: This frosting for brownies can be frozen in a freezer safe bag for up to 1 month. When ready to use, thaw in the refrigerator over night. You might need to add 1 teaspoon of milk to make it creamy again.
