You simply cannot resist these super- duper cupcakes, with indulgent ingredients in their filling, which are so divine. Semi-sweet chocolate, cocoa, and chopped walnuts, all so very decadent. These brownie cupcakes are just the thing for offering to friends when they drop in for tea, or even munching yourself anytime that you feel like a snack. The whole family will be keen to join you and devour a batch of them so fast, that you are forced to make more immediately.
