Instructions

1. Prepare an 8×8-inch (20×20 cm) baking pan by lining it with parchment paper. Ensure paper edges hang over sides for easy removal. Set oven temperature to 350°F (175°C).
2. Melt ¾ cup (170 g) unsalted butter completely. Whisk 1 cup (200 g) granulated sugar, ½ cup (100 g) brown sugar, 2 large eggs, and 1 extra egg yolk until smooth and glossy.
3. Sift ¾ cup (90 g) all-purpose flour, ¾ cup (75 g) unsweetened cocoa powder, and ½ teaspoon salt into the wet mixture. Stir gently until just combined. Add ½ cup (85 g) semi-sweet chocolate chips.
4. Spread brownie batter evenly across the prepared pan using a spatula. Make sure corners and edges are covered.
5. In a separate bowl, cream ½ cup (113 g) softened unsalted butter, ½ cup (100 g) brown sugar, and ¼ cup (50 g) granulated sugar until light and fluffy.
6. Mix ½ cup (125 g) creamy peanut butter into the butter mixture. Add 1 large egg and 1 teaspoon vanilla extract. Blend thoroughly.
7. Incorporate ¾ cup (90 g) all-purpose flour, ½ cup (45 g) rolled oats, ½ teaspoon baking soda, and ¼ teaspoon salt. Mix until just combined.
8. Fold ½ cup (85 g) mini M&M’s and ½ cup (85 g) chocolate chips into the monster cookie dough.
9. Drop spoonfuls of monster cookie dough across the brownie layer. Use a knife to create gentle swirls, keeping some brownie visible.
10. Bake at 350°F (175°C) for 32-35 minutes. Check doneness with a toothpick – it should have a few moist crumbs when removed.
