This rich and creamy Milk Chocolate Frosting is a bakery-style buttercream that’s easy enough for bakers of all levels to make with minimal ingredients. Use it to make decadent chocolatey swirls on cupcakes, cakes, cookies, and more!
In the microwave or in a saucepan, melt together ½ cup (1 stick) of the butter, cocoa powder, and milk, stir until smooth. Cool to room temperature.
In another large bowl, or a stand mixer fitted with the paddle attachment, beat remaining 1 cup (2 sticks) butter and vanilla together, then add cooled cocoa mixture.
Add confectioners' sugar 1 cup at a time, blending with each addition, until frosting is smooth and creamy.
*For a stiffer frosting for piping, use all 8 cups of sugar. For a softer frosting for swooping on a cake, use just 7 cups of confectioners' sugar.
Use frosting immediately or store in the fridge or freezer until ready to use. Bring almost to room temperature and beat until smooth before using.
Melt cocoa and butter: Melting the cocoa and butter together activates the chocolate flavors in the cocoa. It also helps make the frosting smooth and creamy.
Adjust consistency: If you'd like to make a stiffer frosting for piping, use all 8 cups of sugar. To make a softer frosting for swooping on a cake, use 7 cups of confectioners' sugar.
