To make the chocolate glaze topping, just add 1/4 cup heavy cream, 1 cup powdered sugar, 3 tablespoons cocoa powder, and 1/2 tablespoon vanilla extract. If the glaze is too sticky, add water or milk. If you want the glaze to be shinier, use 3/4 cup of chocolate chips instead of the cocoa powder and add a teaspoon of coconut oil.
