Back to School Treat: Peanut Butter Cup Oreo Cupcakes

I love the first day back to school, and a big reason is because of our tradition of making — and, of course, eating — a yummy treat when the day is done.

This year, my middle daughter was looking online and found some delicious looking cupcakes. I combined a few recipes and came up with this:

Peanut Butter Cup Oreo Cupcakes

yield: 20 cupcakes


  • 1 cup all-purpose flour
  • 1/2 cup cocoa powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • pinch of salt
  • 1 ounce bittersweet or semisweet chocolate, finely chopped
  • 1/2 cup butter, softened to room temperature
  • 1 cup sugar
  • 2 eggs
  • 2 teaspoons vanilla
  • 3/4 cup buttermilk
  • 20 Oreos
  • 20 mini Reese cups, unwrapped


Preheat the oven to 350 degrees.  Line 20 muffin cups with paper liners.  Place an oreo in the bottom of each liner.

Sift the flour, cocoa powder, baking soda, baking powder, and salt into a medium bowl.  Stir in the chopped chocolate.

In a large bowl or the bowl of stand mixer, beat the butter and sugar on high until fluffy, about 2-3 minutes.  Beat in the eggs one at a time, scraping down the bowl after each addition.  Beat in the vanilla.  With the mixer on low, slowly pour in the buttermilk and allow to incorporate for 30 seconds.

Pour in the flour mixture and beat on medium until fully incorporated, about 1 minute.  Divide the batter evenly among the paper liners, filling each about 2/3 full.

Bake for 8 minutes, then remove from oven and press a peanut butter cup into the center of each cupcake.  Allow to bake for 10 more minutes, or until a toothpick inserted near the center comes out clean.  Allow to cool for 5 minutes, then remove cupcakes from the muffin tin to cool completely on a wire rack.  Frost with peanut butter frosting. YUM!

  1. Yummy! I love seeing how the girls dressed on their first day of school, too. Each one is an individual.
    Why not attempt to make some delicious dessert for each Friday this school year? It would give the girls, and you, an incentive to march on through each week, because “Friday’s comin'”!

  2. Another Oreo treat in the same sort of theme: Place some brownie batter, then an Oreo, and then top with more brownie batter in muffin tin cups. Bake until brownie are lightly cooked. Don’t overbake! Very yummy!
