S’more Brookies

I don’t know who decided brownie batter and cookie dough needed to be put together, but whoever did is a genius…especially when using premade cookie dough and box brownie batter. Sometimes though, even a genius idea can be spruced up a tad.

Marshmallows, caramel, and peanut butter are all additional flavors that can add to the brookie. When I decided I wanted to make a quick and tasty holiday baked good, I knew I wanted to add in some of these flavors. That’s when the s’more brookie idea came to me.

I also decided I needed to go big with this treat. I used my large muffin pan, but this can easily be recreated in a regular sized muffin pan or even the mini sized muffin pan.

  • muffin pan
  • cupcake liners


  • 24 count premade chocolate chip cookie dough
  • 1 box brownie mix plus ingredients needed for the mix
  • 12 large marshmallows
  • 12 regular sized Reese’s Peanut Butter Cups


  • Line the muffin pan with cupcake liners then take 2 sections of the premade cookie dough and mold them to fit the bottom of the liners.
  • Place an unwrapped Reese’s Peanut Butter Cup over the cookie dough.
  • Make the brownie batter according to the directions on the brownie mix box. Pour equal amounts into the muffin tins over top of the peanut butter cups. Bake in a 350°F oven for 25-30 minutes, or until the brownie batter is completely cooked through.
  • Take out of the oven and place a marshmallow over top of each muffin cup. Place back into the oven on broil and allow the marshmallows to toast on the top. This step is quick so keep an eye on the marshmallows. Remove from oven and serve immediately. If you are not going to serve immediately, wait to do the marshmallow step until right before you serve. Store in an airtight container for up to a week.
