Creamy Chocolate Frosting

0 Combine butter, cocoa powder, honey, and vanilla extract. With a handheld mixer or the whip / whisk attachment on a stand mixer, start on low until the ingredients are combined. Increase the speed to high and beat until the ingredients are very even and smooth. 
1 Add powdered sugar and milk and continue mixing until the frosting is very fluffy and smooth. If the frosting still seems too thick to easily spread, add more milk, a small amount at a time as needed, beating after each addition. 
2 Spread frosting over cake or store according to notes below. (Note: If frosting a freshly baked cake, allow the cake to cool completely before frosting.)
