This is my new favorite chocolate frosting recipe, that yes, calls for 3 sticks of butter.
3 Sticks Butter Chocolate Frosting
3 sticks unsalted butter, soft
1 cup unsweetened cocoa powder
5 cups powdered sugar
1/2 cup whole milk
1 tablespoon pure vanilla extract
1/2 teaspoon salt
Combine softened unsalted butter with unsweetened cocoa powder and beat until super smooth, shiny and combined.
Add in 1 cup powdered sugar at a time, splashing in a little milk after each addition. Beat well.
Beat in the pure vanilla extract and salt.
Beat for a couple of minutes.
Use as desired.
