This is the best espresso buttercream frosting and only requires just 5 ingredients in order to make! Coffee lovers will absolutely love putting this on these easy espresso cupcakes, chocolate cake, and even vanilla cupcakes.
In the bowl of an electric stand mixer using the paddle attachment, beat the butter on high speed until creamy (about 1-2 minutes). Add the powdered sugar, heavy whipping cream, espresso powder, and vanilla extract and mix on low speed until combined (about 30 seconds).
Then increase the speed to high and beat for another 1-2 minutes (frosting should be light and creamy).
Use it to frost your cupcakes, cake, or even brownies!
Notes
Espresso Powder: Do not substitute this ingredient with instant coffee powder or instant coffee granules. The flavor will ruin the frosting. You can find espresso powder at your local grocery store or online.
Light & Fluffy Texture: Adding just a bit of heavy whipping cream will make your frosting super smooth and creamy. Definitely don't skip this ingredient!
Room Temperature: The butter needs to be at room temperature in order to create the perfect consistency of buttercream frosting.
