Ingredients for Monster Cookie Fudgy Brownies
Here’s what you’ll need to make this delicious Monster Cookie Fudgy Brownies:
1 box (18.3 oz) milk chocolate brownie mix – This will form the fudgy base of your brownies, providing rich chocolate flavor.
1/3 cup creamy peanut butter – Adds a delightful nutty flavor and helps create a gooey texture in the cookie topping.
2 tablespoons butter, softened – Enhances the richness and maintains moisture in the cookie layer.
1/4 cup brown sugar – This gives a deeper sweetness and chewy texture to the cookie dough.
2 tablespoons granulated sugar – Balances the flavors and adds a delightful crunch.
1 large egg – Binds the ingredients together and helps with the overall structure.
1/2 teaspoon vanilla extract – Infuses a warm, sweet aroma into the cookie layer.
1/3 cup all-purpose flour – Provides structure to the cookie dough; the right amount keeps them beautifully chewy.
1/4 teaspoon baking soda – Acts as a leavening agent, helping the cookie topping rise just right.
1/4 teaspoon salt – Enhances all the sweet flavors.
1/4 cup quick oats – Adds a lovely chewy texture and nutty flavor to the cookie base.
1/4 cup miniature chocolate chips – For pockets of melty chocolate in every bite, making these brownies even more irresistible.
1/4 cup mini M&M’s (plus more for on top) – Topping them off with more M&M’s adds color and whimsy, ensuring they look as fun as they taste.
How to Make Monster Cookie Fudgy Brownies
Follow these simple steps to prepare this delicious Monster Cookie Fudgy Brownies:
Step 1: Preheat the Oven
Start by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). While the oven warms up, prepare your baking pan by spraying it with cooking spray or lining it with parchment paper for easy removal later.
Step 2: Prepare the Brownie Base
Grab the brownie mix and prepare it according to the directions on the box. This typically involves adding eggs, water, and oil. Once combined, pour the brownie batter into the prepared baking pan, spreading it evenly across the bottom.
Step 3: Make the Cookie Dough
In a mixing bowl, combine peanut butter and softened butter. Using a fork, blend until well combined. Add the brown sugar, granulated sugar, egg, and vanilla extract. Mix thoroughly until the mixture is creamy and smooth.
Step 4: Fold in the Dry Ingredients
Next, sprinkle in the flour, baking soda, and salt. Gently fold these dry ingredients into your peanut butter mixture until just combined. Be careful not to overmix. Then, fold in the quick oats, chocolate chips, and mini M&M’s until evenly distributed.
Step 5: Layer the Cookie Dough
With your hands, take spoonfuls of the cookie dough and drop them over the brownie mix. You can flatten them slightly if you prefer, but rustic dollops work just as wonderfully. Just make sure they cover most of the brownie batter.
Step 6: Bake to Perfection
Pop your baking pan in the oven and let it bake for 25-35 minutes. Keep an eye on them; the brownies should be set in the center. Use a toothpick to check for doneness. If it comes out with a few moist crumbs but not wet batter, they’re ready!
Once they’re done baking, allow your Monster Cookie Fudgy Brownies to cool in the pan for about 30 minutes to an hour. Afterward, slice them into squares, serve, and enjoy! These decadent bars are perfect for sharing with friends, snuggling up on the couch, or celebrating any occasion.
