How to Make Monster Cookie Dough Cupcakes

Step 1: Bake the Cupcakes

Prepare cupcakes using cake mix according to package instructions. Let cool completely before adding the filling.

Step 2: Make the Edible Cookie Dough

In a bowl, cream together butter, sugars, and peanut butter. Add vanilla and milk. Mix in oats, heat-treated flour (bake at 350°F for 5 minutes), chocolate chips, and M&Ms. Mix until dough forms. Refrigerate for 15–20 minutes.

Step 3: Fill the Cupcakes

Once cupcakes are cool, use a spoon or cupcake corer to remove a small section from the center. Roll cookie dough into small balls and stuff into each cupcake hole. Flatten to make level with the cupcake top.

Step 4: Make the Peanut Butter Frosting

Beat butter and peanut butter until smooth. Add powdered sugar and beat until combined. Slowly add cream until fluffy. Mix in vanilla extract.

Pipe frosting onto filled cupcakes and top with more mini M&Ms and chocolate chips if desired.
