I cannot believe that most of my friends and I are turning 30 this year!  30 seems like a big milestone to me.  When you’re still in your twenties, you can get away with things because you are in your “early adult” years.  Mistakes are understandable, confusion about life goals is still acceptable and not being sure about how you feel about all of the responsibilities you have is normal.  I can remember when turning 30 seemed so far away.  Now it will be here in just a few months….

My good friend turned 30 a few weeks ago and I wanted to make her an extra special birthday treat to mark this milestone.  Nothing says birthday like cupcakes to me and what is more over-the-top than cupcakes stuffed with cookie dough?  All of the best things rolled into one dessert.

Using chocolate chip cookie dough would be just as delicious with this recipe, but I went with peanut butter because almost everyone gets excited about chocolate and peanut butter together.  The trifecta of soft chocolate cake, peanut butter cookie dough and creamy chocolate buttercream is enough to make anyone forget about turning yet another year older.

Peanut Butter Cookie Dough-Stuffed Chocolate Cupcakes with Chocolate Buttercream

Prep Time: 1 hour

Cook Time: 8 minutes

Total Time: 1 hour, 15 minutes

Yield: 40 mini cupcakes


    For the cupcakes:
  • 1 cup flour
  • 1/3 cup cocoa powder
  • 1/4 cup sugar
  • 1/2 cup packed brown sugar
  • 3/4 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 3/4 cup milk
  • 1/2 cup canola oil
  • 1 tsp vanilla
  • 2 eggs
  • For the cookie dough:
  • 1/4 cup (4 Tbsp) unsalted butter, softened
  • 1/4 cup creamy peanut butter
  • 1/4 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 Tbsp milk
  • 1 tsp vanilla
  • 1 1/4 cups flour
  • 1/4 tsp salt
  • For the chocolate buttercream:
  • 1/2 cup (8 Tbsp) unsalted butter, softened
  • 1/2 cup semisweet chocolate chips, melted
  • 1 1/2 cups powdered sugar
  • 1 tsp vanilla
  • 1 Tbsp milk


    For the cupcakes:
  1. Preheat oven to 350 degrees and line mini muffin pan with paper liners.
  2. In a large bowl, combine flour, cocoa powder, sugar, brown sugar, baking soda, baking powder and salt.
  3. Add milk, oil, vanilla and eggs and mix until well incorporated.
  4. Fill paper liners 2/3 full of batter and bake for 8 minutes or until toothpick inserted into center of cupcakes comes out clean.
  5. Cool.
  6. For the cookie dough:
  7. While the cupcakes are baking, make the cookie dough by beating together the butter, peanut butter and sugars in a medium bowl using an electric mixer.
  8. Add milk and vanilla and mix to combine.
  9. Add flour and salt and mix until well incorporated.
  10. For the chocolate buttercream:
  11. In a small bowl, cream together butter and melted chocolate using a mixer. Add powdered sugar, vanilla and milk and mix until smooth. If frosting is thicker than you would like, add milk 1 tsp at a time until desired consistency is reached. If too thin, add powdered sugar.
  12. Assembly:
  13. Once cupcakes have cooled, use a small paring knife to cut a small ~1-inch hole in the center of the cakes.
  14. Roll cookie dough into ~1-inch balls and stuff inside the cavities you have created in the cupcakes.
  15. Pipe or spread buttercream on top of cupcakes to cover cookie dough and serve.

    This dessert has everything I love all rolled into one glorious cupcake. I love that you made peanut butter cookie dough instead of chocolate chip. Nothing beats the combination of peanut butter and chocolate!! 🙂

    I’ve been meaning to try a chocolate buttercream…

    I can’t believe how huge that cupcake pan is. I had to actually count how many spots there were!

    These mini cupcakes are amazing! And I bet they’re so dangerous to have around the house too. I bet I wouldn’t be able to stop at just 1. Or 5 actually.
