    1/2 cup cocoa powder (or more)
    dash of salt

Directions:

Margin should be at room temperature when being placed in bowl. Blend until mushy, and then add vegan powdered sugar, salt, vanilla, chocolate and soymilk. You can add in more soymilk to make it a bit smoother but not too much. Spread on cake and enjoy.
