Chocolate Peanut Butter Buttercream Cupcakes

I wish I could say that I’m a huge chocolate peanut butter combo fan, but I’m actually more of a vanilla and rainbow sprinkles kind of girl. That being said, when you haven’t eaten something for a long time, I think your mind/palate start to crave what it considers exotic.

A girl can only eat so much yogurt.

Stuffed inside the moist chocolate cake are bits of gooey semisweet chocolate chunks, and the peanut butter buttercream is light and creamy-not at all that cloying stickiness peanut butter icing sometimes has.

Even better? The cupcakes can be made in just one bowl and it doesn’t even need beaters. The buttercream you ask? Well, okay, it’s a tad more involved, but still much easier than classic buttercreams. It’s worth the smidge of effort.

And in the words of my dad who helped me eat one immediately: “I love the aftertaste of this cupcake…almost like a fine wine.” Ah yes, if anyone can turn cupcakes into a refined ordeal, it’s my family 😉

  • An electric mixer
  • A metal bowl that fits over a pot of water or a double boiler
  • Whisk


For the cake:

  • 1 1/4 cups flour

  • 1 tsp. baking soda
  • 1/4 cup vegetable oil
  • 1 tsp. vanilla extract
  • 4 oz. finely chopped semisweet chocolate

For the buttercream: [note: this is NOT a pipe-able frosting. Think of this more like a meringue than a stiff buttercream]

  • 1/2 cup sugar
  • Egg whites of 2 large eggs
  • 1 1/2 tsp. vanilla extract
  • 1/4 cup creamy peanut butter
  • 6 Tbl. chilled, unsalted butter cut into 1/4-inch cubes

Using an electric mixer, beat on high speed until cooler and thick, 5 min. Beat in vanilla, then peanut butter. With mixer running, add butter pieces a little at a time, beating THOROUGHLY to blend between additions. Season with salt.

Frost cupcakes and sprinkle with chopped chocolate and peanuts. Keep a few days in an airtight container at room temp., then refrigerate up to a few more days.
