Melt Chocolate

Melting chocolate can be a little tricky because chocolate often hardens after melting. The easiest tip is to use a low setting in the microwave so that the chocolate melts slowly.

You can also mix a dash of coconut oil with sugar-free chocolate and melt it over a double boiler. Once the chocolate has melted, drizzle it over the peanut butter layer and spread it over the top evenly.
