Ingredients You’ll Need

This recipe uses a handful of straightforward yet crucial ingredients that come together to create the perfect balance of fudgy brownie and monster cookie dough. Each component plays a vital part from richness and moisture to texture and bursts of color.

• White granulated sugar: Adds sweetness and helps create that luscious brownie crust.
• Large eggs and egg yolk: Provide structure and richness for the fudgy brownie base.
• Unsalted butter: Brings a creamy, rich flavor essential for both the brownie and cookie dough.
• Canola or vegetable oil: Keeps the brownies moist and dense without being greasy.
• Pure vanilla extract: Enhances the overall flavor depth in both components.
• All-purpose flour: Gives body to both the brownie and cookie layers.
• Unsweetened Dutch-process cocoa powder: Delivers that deep, chocolatey intensity in the brownies.
• Cornstarch: Helps create a delicate texture in the brownie and cookie dough alike.
• Salt: Balances flavors and amplifies the sweetness.
• Semi-sweet and milk chocolate chips: Add melty pockets of chocolate throughout the brownies.
• Brown sugar: Contributes moisture and chewiness to the monster cookie dough.
• Peanut butter: Infuses the cookie dough with a creamy, nutty richness that pairs perfectly with chocolate.
• Quick oats: There for chewiness and that classic monster cookie texture.
• Mini M&M’s: Provide fun bursts of color and sweet crunch in the cookie dough.

How to Make Monster Cookie Fudgy Brownies

Step 1: Prepare the Monster Cookie Dough

Start by mixing all the dry ingredients together—flour, cornstarch, baking soda, baking powder, and salt. Then, using a mixer, cream the butter and sugars until light and fluffy. This step is key for that soft, melt-in-your-mouth cookie dough texture. Add peanut butter, followed by vanilla and egg, blending everything smoothly. Slowly incorporate the dry ingredients, then fold in oats, chocolate chips, and those irresistible mini M&M’s. Pop the dough into the refrigerator to chill for about 40 minutes. Chilling ensures the cookie dough will hold its shape beautifully when baked on top of the brownies.

Step 2: Get the Brownie Batter Ready

While the dough chills, preheat your oven and prep a 9×9 pan with non-stick spray and parchment paper to make sure your brownies come out in one glorious piece. Whisk together the flour, cocoa powder, cornstarch, and salt. Next, beat the sugar, eggs, and additional egg yolk for a full five minutes until the mixture is airy and pale. Melt the butter and add it along with the oil and vanilla to the eggs. Finally, fold in the dry ingredients gently, then stir in both types of chocolate chips. Smooth this rich batter into the pan for a fudgy base that will be the perfect backdrop for your monster cookie topping.

Step 3: Bake, Top, and Finish

Bake the brownie layer uncovered for 15 minutes, just until it’s starting to set but still soft. Then remove it from the oven, grab your chilled cookie dough, and start flattening small discs to place all over the brownie. This layering step is where magic happens—pockets of cookie dough nestled into fudgy brownie create incredible bites. Return the pan to the oven and bake for another 20 minutes. To make sure the cookie dough tops don’t brown too quickly, tent loosely with foil and bake for 5 to 10 more minutes until both layers are set but still chewy and fudgy. Cooling completely is crucial to achieve neat, perfect slices.

How to Serve Monster Cookie Fudgy Brownies

Garnishes

While the Monster Cookie Fudgy Brownies are a crowd-pleaser all on their own, a scoop of vanilla ice cream or a drizzle of caramel sauce on top can elevate them into dessert star territory. Sprinkle a few extra mini M&M’s or chocolate chips over warm brownies for a colorful, playful presentation that excites the eyes and palate.

Side Dishes

These brownies are rich and satisfying, so pairing them with fresh berries can offer a refreshing contrast. A simple glass of cold milk or a cup of rich coffee complements their intense chocolate-peanut buttery flavor perfectly, balancing indulgence with a classic comfort feel.

Creative Ways to Present

Try cutting the Monster Cookie Fudgy Brownies into bite-sized squares and stacking them on a dessert platter for parties or bake sale-style events. You could also sandwich a scoop of ice cream between two brownie squares for an easy frozen treat. Wrapping individual brownies in parchment paper tied with twine makes for adorable edible gifts that let the recipe’s charm shine.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Monster Cookie Fudgy Brownies stored in an airtight container at room temperature for up to four days. Make sure they are completely cool before storing to preserve that perfect fudgy texture without becoming soggy.

Freezing

If you want to save these brownies for longer, they freeze beautifully. Wrap them tightly in plastic wrap and place in a freezer bag or container. They will keep well for up to three months, allowing you to enjoy that delightful monster cookie and brownie combination anytime you have a craving.

Reheating

To enjoy the brownies warm, simply microwave individual portions for 15-20 seconds or reheat in a low-temperature oven until just warmed through. Avoid overheating, as you want to maintain the moist, fudgy texture and soft cookie dough contrast.

FAQs

Can I use crunchy peanut butter instead of creamy in the cookie dough?

Absolutely! Using crunchy peanut butter will add a bit more texture to your cookie dough topping, which can be delicious, but the creamy version helps keep the dough smooth and easier to mix and spread across the brownies.

What if I don’t have mini M&M’s? Can I substitute something?

Feel free to swap mini M&M’s for regular-sized ones, chocolate chips, or even chopped nuts. The mini M&M’s add fun color and a sweet crunch, but other add-ins can work great depending on your preferences.

Can I make the brownies or cookie dough in advance separately?

Yes! Both components can be made ahead and stored in the fridge. Just assemble and bake them together when you’re ready to enjoy the final magic of Monster Cookie Fudgy Brownies.

How do I know when the brownies and cookie dough are properly baked?

You want the brownies to have a slightly set top after 15 minutes before adding the cookie dough. After adding the dough, bake until there’s no jiggle in the center and the cookie dough looks set but still soft to the touch. Using foil to tent the top prevents over-browning.

Can I double the recipe for a larger batch?

Yes, doubling the recipe is possible! Use a larger pan, like a 9×13, and adjust baking times accordingly—starting with the same steps and checking doneness with a toothpick and visual cues is best.
