Ingredients You’ll Need

These ingredients may seem straightforward, but each one plays an essential role in creating the perfect balance of fudgy brownie richness and monster cookie texture. From creamy peanut butter to a blend of chocolate chips and vibrant mini M&M’s, the components work together beautifully.

• White granulated sugar: Sweetens the brownies and helps develop a tender crumb.
• Large eggs and egg yolk: Adds moisture and structure, giving the brownies their fudgy consistency.
• Unsalted butter and oil: Provides richness and that melt-in-your-mouth texture.
• Pure vanilla extract: Enhances all the flavors with warm, aromatic notes.
• All-purpose flour: The base for both the cookie dough and brownie batter, giving body and chew.
• Unsweetened Dutch-process cocoa powder: Offers deep chocolate flavor and a dark, rich color.
• Cornstarch: Helps give the brownies softness by tenderizing the flour’s gluten.
• Salt: Balances sweetness and amplifies chocolate notes.
• Chocolate chips (semi-sweet and milk): Adds pockets of melty, indulgent chocolate throughout.
• Brown sugar: Brings moisture and subtle caramel notes to the cookie dough.
• Peanut butter (creamy): Infuses the cookies with nutty richness and chewiness.
• Baking soda and baking powder: Ensure the cookie dough rises just enough to be tender without losing chew.
• Quick oats: Adds classic monster cookie chew and heartiness.
• Mini chocolate chips and mini M&M’s: Provide bursts of chocolate and playful pops of color for that signature monster cookie look.

How to Make Monster Cookie Fudgy Brownies

Step 1: Preparing the Monster Cookie Dough

Begin by mixing all your dry ingredients — flour, cornstarch, baking soda, baking powder, and salt — to create an even base for the cookie dough. In a separate bowl, beat the butter and sugars together until light and fluffy; this aeration is crucial for that perfect texture. Next, incorporate the creamy peanut butter, followed by the egg and vanilla extract, combining well after each addition. Fold in your dry ingredients then gently stir in the oats, mini chocolate chips, and mini M&M’s. Cover the dough and chill it for about 40 minutes. This resting period not only firms it up for easier handling but helps meld the flavors beautifully.

Step 2: Making the Fudgy Brownie Batter

While your cookie dough chills, preheat your oven to 325°F and prepare a 9×9 pan with non-stick spray and parchment paper on the bottom and two sides. Whisk together the flour, cocoa powder, cornstarch, and salt in a medium bowl. Then, in your mixer, beat the sugar with eggs and egg yolk using a whisk attachment for five minutes until the mixture becomes light and fluffy—this is key for the airy yet dense brownie texture. Melt the butter and let it cool slightly before blending it with oil and vanilla into the egg mixture. Carefully fold in your dry ingredients and both types of chocolate chips, ensuring you preserve the batter’s airiness for rich, fudgy brownies.

Step 3: Baking and Assembling the Monster Cookie Fudgy Brownies

Pour the brownie batter into your prepared pan and smooth it evenly. Bake for 15 minutes until the top of the brownies is just beginning to set but still soft underneath. Remove the cookie dough from the fridge and pinch off small handfuls, flattening them into discs to layer over the partially baked brownies. Continue covering the surface with these cookie dough pieces. Return the pan to the oven, loosely cover with foil to prevent over-browning of the cookie layer, and bake for another 20 to 25 minutes until everything is set and firm without jiggle. Let the brownies cool completely on a rack before slicing, allowing the brownie and cookie layers to meld perfectly.

How to Serve Monster Cookie Fudgy Brownies

Garnishes

While these brownies are delicious on their own, a light dusting of powdered sugar or a drizzle of melted chocolate can elevate their presentation. For a fun, extra pop, sprinkle a few more mini M&M’s on top just after baking to add a colorful finish that echoes the monster cookie vibe.

Side Dishes

These brownies pair wonderfully with simple sides like a scoop of vanilla ice cream or a dollop of whipped cream to balance their rich chocolaty and nutty flavors. A cold glass of milk or a creamy latte also makes a lovely companion for an indulgent snack or dessert.

Creative Ways to Present

For parties or special occasions, cut the Monster Cookie Fudgy Brownies into small squares and serve on a decorative platter garnished with fresh berries or mint leaves. You could also layer them in a dessert trifle with whipped cream and extra mini M&M’s for a playful, crowd-pleasing dessert display.

Make Ahead and Storage

Storing Leftovers

Store leftover Monster Cookie Fudgy Brownies in an airtight container at room temperature for up to 3 days. This keeps them moist and fudgy while maintaining the crispness of the cookie layer. If your room is warm, storing them in the fridge works too but brings slight firmness to the butter.

Freezing

These brownies freeze beautifully. Wrap individual portions tightly with plastic wrap and place them in a freezer-safe container or bag. They can be frozen for up to 3 months. Thaw at room temperature before serving to restore their fudgy texture.

Reheating

To enjoy your Monster Cookie Fudgy Brownies warm, reheat in the microwave for about 15 to 20 seconds or until warmed through. This releases the chocolate chips’ melty goodness and softens the peanut butter cookie layer, making every bite heavenly.

FAQs

What makes Monster Cookie Fudgy Brownies different from regular brownies?

Monster Cookie Fudgy Brownies are unique because they combine two favorites: rich, fudgy brownies and soft, chewy monster cookies loaded with oats, peanut butter, and colorful M&M’s. This combo delivers multiple textures and flavors in one bite.

Can I substitute peanut butter in the cookie dough?

Yes, you can swap peanut butter for almond or cashew butter, but keep in mind this will slightly alter the flavor. Using a creamy nut butter works best to maintain that chewy, rich texture.

Do I need to chill the cookie dough before baking?

Absolutely! Chilling the cookie dough helps it firm up so it holds its shape when layered on top of the brownies. It also enhances the flavor development for the best-tasting Monster Cookie Fudgy Brownies.

Is it okay to use different types of chocolate chips?

Definitely! Feel free to experiment with dark, semi-sweet, milk, or even white chocolate chips to suit your taste. Mixing various chocolates can add complexity and extra gooeyness.

How do I know when the Monster Cookie Fudgy Brownies are done baking?

You want the brownies to be set with no visible jiggle, and the cookie topping should look baked through but not overdone. A toothpick inserted into the brownie layer should come out with moist crumbs but not raw batter.
