Reese's Peanut Butter Cups have long been one of my favorite foods. Here in Paris, there are only a handful of stores that sell them, and they don't come cheap! I've tried various incarnations of peanut butter and chocolate cupcake recipes but I always come back to my tested and true -- chocolate brownie cupcake with whipped peanut butter frosting. It's one of my personal favorites and you'll find it on the Sugar Daze menu under the Old School section: Chocobutter. If you're a peanut butter-chocoholic like me, this one's got your name on it!
