This dramatic black buttercream stars as crusted lava in the Amazing Erupting Volcano Cake. It also works wonderfully for Halloween cupcakes, or anywhere else you need a black frosting.

- In a small saucepan melt the butter.
- Remove from the heat and whisk in the regular and black cocoa and vanilla extract, mixing until fully combined.
