This is one of my favorite recipes for an American dessert known as black bottom cupcakes. I've changed the chocolate cake component a little bit over the years, but the topping remains the same. Be careful when filling the muffin cups because these rise quite a bit. My cupcake wrappers are slightly larger so I make 18, but if using the small pastel colored liners from the grocery store you may want to make 20.
I use slightly larger cupcake liners/papers which I buy on-line so I get 18 cupcakes. If you are using typical cupcake liners from the grocery store, you may want to use 20 liners.
