– 1/2 cup powdered sugar 
– 3 tbsp brown sugar

**For Monster Cookie Dough Frosting:**
– 2 sticks butter, room temperature
– 1/4 cup brown sugar
– 1/4 cup smooth peanut butter
– 2 tsp vanilla extract
– 6-8 cups powdered sugar
– 1 cup mini chocolate chips
– 1 cup mini M&M’s
Instructions
1. **Prepare Cookie Dough:** In a bowl, mix cream cheese, butter, and peanut butter until smooth. Add powdered sugar, brown sugar, flour, vanilla, and salt, mixing well. Fold in oats, chocolate chips, and M&M’s. Form into balls and freeze on a baking sheet.
2. **Bake Cupcakes:** Follow the instructions on the cake mix box and pour the batter into lined muffin tins. Press a frozen cookie dough ball into the center of each cupcake. Bake at 350°F for 14-16 minutes. Allow to cool completely.
3. **Make Frosting:** Beat together butter, brown sugar, peanut butter, and vanilla until creamy. Gradually mix in powdered sugar and then stir in mini chocolate chips.
4. **Decorate:** Pipe the frosting onto each cupcake, covering the cookie dough center. Top with mini M&M’s.
Notes
– Ensure cookie dough balls are frozen solid to prevent them from baking through.
– For a less sweet option, reduce the powdered sugar in the frosting.
