Instructions
- Prepare Monster Cookie Dry Ingredients: In a medium mixing bowl, whisk together flour, cornstarch, baking soda, baking powder, and salt until well combined.
- Mix Monster Cookie Wet Ingredients: Using a mixer, beat the softened butter, brown sugar, and white sugar together on medium speed for 1 minute until light and fluffy. Add peanut butter and beat for another minute until fully incorporated.
- Add Egg and Vanilla: Mix in the vanilla extract and the large egg until fully combined. Scrape down the sides of the bowl and mix an additional 20 seconds to ensure a smooth batter.
- Combine Dry and Wet for Monster Cookies: Gradually add the dry ingredients to the wet mixture and mix until just combined. Fold in the quick oats, mini chocolate chips, and mini M&M’s gently. Cover and refrigerate the dough for 40 minutes to chill.
- Preheat for Brownies: When the cookie dough is almost done chilling, preheat your oven to 325°F (163°C). Prepare a 9×9 inch baking pan by spraying it with non-stick baking spray and lining the bottom and two sides with parchment paper for easy removal.
- Mix Brownie Dry Ingredients: In a medium bowl, whisk together the flour, cocoa powder, cornstarch, and salt. Set aside.
- Beat Brownie Eggs and Sugar: Using a mixer with a whisk attachment, beat the white sugar, eggs, and egg yolk for 5 minutes until the mixture is very light, fluffy, and thickened.
- Add Butter, Oil, and Vanilla: Melt the butter and let it cool slightly. While beating eggs, add the melted butter, oil, and vanilla extract on low speed until combined.
- Fold in Brownie Dry Ingredients and Chips: Remove the bowl from the mixer and gently fold in the dry ingredients using a rubber spatula with care to maintain airiness. Then fold in the semi-sweet and milk chocolate chips evenly.
- Pour Brownie Batter: Pour the brownie batter into the prepared pan, spreading it evenly with a rubber spatula smoothing into corners.
- Bake Brownies Partially: Bake in the preheated oven for 15 minutes until the top is slightly set but not fully baked. Remove from oven.
- Top Brownies with Cookie Dough: Remove cookie dough from refrigerator. Take small handfuls and flatten into discs. Arrange these discs evenly on top of the partially baked brownie layer.
- Finish Baking: Return the pan to the oven and bake for another 20 minutes. Loosely cover the top with foil to prevent over-browning. Continue baking an additional 5-10 minutes until the cookie dough and brownie are set with no jiggle.
- Cool Completely: Remove from oven and place the pan on a cooling rack. Allow the brownies to cool completely to room temperature before cutting to maintain clean slices and a fudgy texture.
- Store: Store the Monster Cookie Fudgy Brownies at room temperature in an airtight container for up to 3-4 days for best freshness.
Notes
- Ensure all butter and eggs are at room temperature for smooth mixing and better texture.
- Line the pan with parchment on the sides as well as the bottom to easily lift the brownies out for clean cutting.
- Chilling the cookie dough helps prevent it from melting into the brownie layer when baking.
- Do not overmix the brownie batter after adding dry ingredients to keep them fudgy and tender.
- Baking times may vary slightly depending on your oven. Look for no jiggle in the center when done.
- Store brownies at room temperature instead of refrigerating to maintain the fudgy texture.
