Step‑by‑Step Instructions for Monster Cookie Fudgy Brownies
Step 1: Prepare Monster Cookie Dough
In a mixing bowl, whisk together the all-purpose flour, cornstarch, baking soda, baking powder, and salt until evenly combined. In a separate bowl, cream together the melted and slightly cooled unsalted butter with brown sugar and granulated sugar until light and fluffy, about 3 minutes. Mix in the peanut butter, followed by the vanilla extract and egg, blending until fully incorporated. Gradually fold in the dry ingredients, along with the quick oats, mini M&Ms, and chocolate chips. Chill the dough for 40 minutes to firm up.
Step 2: Prepare Brownies
Preheat your oven to 325°F (163°C) and prepare a 9×9-inch baking pan by spraying it with non-stick spray and lining it with parchment paper. In a medium bowl, whisk together the flour, cocoa powder, cornstarch, and salt until well combined. In another bowl, beat the granulated sugar, eggs, and egg yolk together until fluffy, about 4 minutes. Gradually add in the melted butter, oil, and vanilla extract, mixing until smooth. Carefully fold in the dry ingredient mixture along with the semi-sweet and milk chocolate chips.
Step 3: Combine & Bake
Pour the fudgy brownie batter into the prepared pan, spreading it evenly. Bake the brownies in your preheated oven for 15 minutes or until the edges appear set but the center remains slightly underbaked. While the brownies bake, flatten out the chilled cookie dough and distribute it evenly over the baked brownie layer. Return the pan to the oven and continue baking for an additional 20-30 minutes, or until the cookie layer is lightly golden and the brownies are fully set.
Step 4: Cooling
Once baked, remove the Monster Cookie Fudgy Brownies from the oven and allow them to cool completely in the pan on a wire rack. This cooling period is essential for achieving clean squares when cutting. If time is short, place the baking tray in the freezer for about 25 minutes to speed up the cooling process. Once cooled, slice into squares and enjoy the delightful blend of fudgy brownie and chewy cookie textures!
Expert Tips for Monster Cookie Fudgy Brownies

Cool Completely: Allow your brownies to cool entirely before cutting. This ensures clean squares and enhances the rich chocolate flavor of the Monster Cookie Fudgy Brownies.

Accurate Measurements: Be precise with your ingredient measurements, especially flour. Using too much can lead to dense brownies that miss the fudgy mark!
-
Chill the Dough: Don’t skip chilling the cookie dough! This step is crucial for perfect texture and prevents the cookie layer from spreading too much during baking.
-
Underbake Slightly: Bake the brownies just until set, as they will continue to cook slightly after removing from the oven. This keeps them gooey and fudgy.

Monster Cookie Fudgy Brownies Recipe FAQs
How do I select the right ripeness of bananas for these brownies?
Absolutely! For this recipe, bananas aren’t a necessary ingredient, but if you choose to include them in a variation, opt for overripe bananas with brown spots all over. The more brown spots, the sweeter and more flavorful they’ll be, making them perfect for enhancing moisture and sweetness.
How long can I store Monster Cookie Fudgy Brownies and how?
Very! Store your Monster Cookie Fudgy Brownies in an airtight container at room temperature for up to 5 days for optimal freshness. If you prefer a chilled treat, you can refrigerate them for up to a week. Just remember to let them sit at room temperature before enjoying them for the best taste.
Can I freeze these brownies, and if so, how?
Absolutely! To freeze your delicious Monster Cookie Fudgy Brownies, wrap the squares tightly in plastic wrap, then place them in a sealed freezer bag or container. They can be frozen for up to 3 months. When you’re ready to enjoy them, just thaw overnight in the fridge and reheat in the microwave for that warm and fudgy goodness!
Help! My brownies turned out too dense. What went wrong?
No worries; it happens to the best of us! If your brownies are too dense, it could be due to overmeasuring flour or overmixing the batter. Always use a proper measuring cup for flour, spooning flour into the cup and leveling it off. Additionally, mix just until combined – overmixing can incorporate too much air and lead to dense results.
Can I use ingredients like nut butter for those with allergies?
Very much so! If you need to cater to allergies, feel free to substitute peanut butter with sunflower seed butter or cookie butter. Also, make sure to check the labels on your chocolate chips and candies to avoid any cross-contamination with allergens. Enjoy your baking without worries!
What are some alternatives if I don’t have all the ingredients?
Absolutely! If you’re missing some ingredients, there are ways to adapt. For example, you can use applesauce instead of oil to lower fat content, or swap the semi-sweet chocolate chips for dark chocolate for an intense flavor. You can also replace cornstarch with an equal amount of additional flour if it’s not on hand. The more the merrier, so get creative with your substitutions!
