For kids of all ages, this dessert is dense and chocolaty. When was the last time you had a cupcake with sprinkles on top. It is best to use mini muffin tins.

  1. For cupcakes; Preheat oven to 350 degrees.
  2. Line standard (1/3 cup) muffin cups with paper liners (These are really better made in mini muffin tins.) Combine butter, 1/2 cup chocolate chips, and unsweetened chocolate in the top of double broiler set over simmering water.

  8. Transfer cupcakes to rack and cool completely.

Warning: have the ice cold milk on standby!!! These are wonderful, fudgy little bites of heaven. I used a mini-muffin tin and got 36 cupcakes and they baked in about 12 minutes. Be sure and level off the tops before baking, because these do not rise. So delicious, Barb -- thanks for sharing.

This is a very good recipe. I have also seen this one in Bon Appetite, but I don't think that is a good reason to give it a low rating as the last reviewer did. I really enjoyed these ! Thanks for posting this great recipe.

WOW! These are sure to impress - they are WONDERFUL! I made them for a friend's birthday, and was awfully sorry to send the remaining cupcakes home with him. They are rich and the PB frosting is a perfect compliment to the brownie/cupcakes! (P.S. this made a dozen regular sized cupcakes for me... ) Thanks for sharing a GREAT recipe, Barb Gertz!
