- ½ cup (84g) mini M&M's (plus a few more for topping)
- ⅓ cup (55g) chocolate chips (plus a few more for topping)
- ½ cup unsalted butter (cut into eight pieces)
- 1 cup (220g) light brown sugar (packed)

Instructions
- Preheat the oven to 350°F and line a 9×9 square baking pan with parchment paper.
- In a bowl, whisk together flour, baking powder, and salt, then set aside.
- Using a mixer, beat together butter and both sugars until light and fluffy for 1-2 minutes.
- Add the egg and vanilla to the mixture, blending until combined, scraping sides as needed.
- On low speed, mix in the flour mixture until just combined, then stir in M&M's and chocolate chips.
- Chill the cookie dough in the refrigerator while preparing the brownie batter.
- In a microwave-safe bowl, melt the butter and brown sugar together in 30-second increments until combined.
- Set the mixture aside to cool for 5 minutes and combine the dry ingredients in a separate bowl.
- Whisk the eggs and vanilla into the cooled butter mixture, then add the dry ingredients and mix.
- Reserve ½ cup of brownie batter, then pour the rest into the prepared pan, smoothing it out.
- Form irregular shaped pieces of cookie dough and place them on top of the brownie batter.
- Drizzle the reserved brownie batter on top for a marbled effect and add more M&M's and chocolate chips.
- Bake for 30-35 minutes, checking at 28 minutes. The bars are done when a toothpick inserted comes out with moist crumbs. Let cool completely.
Notes
Store any leftover brookies in an airtight container to maintain freshness.
These brookies can be served warm or at room temperature.
For added crunch, consider sprinkling some nuts into the brownie layer.
