This easy chocolate buttercream frosting uses just 4 ingredients to make and results in such a rich chocolate flavor. Dutch-processed cocoa powder gives it the best chocolate flavor that is perfect to pair with triple chocolate cupcakes, moist vanilla cupcakes, or any birthday cake!
In the bowl of an electric stand mixer using the paddle attachment, cream the butter on high speed until light and creamy (2-3 minutes). Add the powdered sugar, cocoa powder, and heavy whipping cream and mix on low speed until combined (30 seconds).
Increase the speed to high and beat for an additional 1-2 minutes until smooth and creamy.
Use it to frost your cupcakes, cakes, or even your favorite brownies!
If you plan on using this frosting within 1-2 days, you can keep it stored in an airtight container on the counter. Otherwise, you can keep it in the refrigerator for up to 1 week. Just pull it out at least 30 minutes before you want to use it so it's not cold.
Notes
Room Temperature: The butter needs to be at room temperature in order to create the perfect consistency of buttercream frosting. If you start with cold butter, you'll have a difficult time getting the frosting to come together.
Baked Desserts: Make sure any dessert you use this frosting on is completely cooled before frosting. If not, the frosting will melt right off.
