Now this is a cupcake with a difference. A doughnut placed in the bottom of a cupcake liner with coffee cupcake batter completely covering it, and, when the coffee and doughnut cupcake comes out of the oven – hey presto! Things have taken a turnabout; the doughnut has floated to the top of the batter. With a frosting of swirled whipped cream, this becomes a decadent coffee doughnut cupcake, which is so delicious, you can’t settle for gobbling only one of them, you just have to have another, or even more.
