Ingredients
Brownies
- 1 1/3 cups white granulated sugar
- 2 large eggs
- 1 egg yolk
- 5 tbsp unsalted butter
- 1/3 cup oil (canola or vegetable)
- 1 tsp pure vanilla extract
- 1/2 cup all-purpose flour
- 3/4 cup unsweetened Dutch-process cocoa powder
- 1 tbsp cornstarch
- 1/4 tsp salt
- 1/2 cup semi-sweet chocolate chips
- 1/2 cup milk chocolate chips
Monster Cookie Dough
- 1/2 cup all-purpose flour
- 1 tsp cornstarch
- 1/2 tsp baking soda
- 1/8 tsp baking powder
- 1/4 tsp salt
- 1/4 cup unsalted butter, room temperature
- 1/3 cup packed brown sugar
- 1/8 cup white granulated sugar
- 1/4 cup creamy peanut butter
- 1 tsp pure vanilla extract
- 1 large egg, room temperature
- 1/2 cup quick oats
- 1/2 cup mini chocolate chips
- 1/2 cup mini M&M’s
Instructions
- Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
- Make the brownie batter: Melt butter, then whisk in sugar, eggs, egg yolk, oil, and vanilla until smooth. Add flour, cocoa powder, cornstarch, and salt. Fold in chocolate chips.
- Spread brownie batter evenly into the baking pan.
- Make the monster cookie dough: Beat butter, brown sugar, and white sugar until creamy. Mix in peanut butter, vanilla, and egg.
- Add flour, cornstarch, baking soda, baking powder, salt, and oats. Fold in mini chocolate chips and mini M&M’s.
- Drop spoonfuls of cookie dough evenly on top of the brownie batter. Gently press down.
- Bake 28–35 minutes, depending on desired fudginess. The center should still be slightly soft.
- Cool completely before slicing for the fudgiest texture.
Notes
- For ultra-fudgy brownies, slightly underbake and chill before cutting.
- Use creamy peanut butter, not natural oily peanut butter.
- Swap M&M’s for Reese’s Pieces for a peanut butter version.
