Monster Cookie Fudgy Brownies Ingredients For the Brownie Base White granulated sugar – Provides sweetness; substitute with brown sugar for a deeper flavor. Large eggs (2) + Egg yolk (1) – Adds richness and aids in structure; ensure they are at room temperature for better mixing. Unsalted butter (5 tbsp + 1/4 cup) – Adds moisture and flavor; can use margarine as a substitute. Canola or vegetable oil (1/3 cup) – Keeps brownies moist and fudgy; oils can be interchanged with melted coconut oil. Pure vanilla extract (1 tsp) – Enhances flavor; imitation vanilla works as a substitute. All-purpose flour (1/2 cup) – Provides structure; for gluten-free, substitute with almond flour. Unsweetened cocoa powder (3/4 cup) – Gives the brownies a rich chocolate flavor; use Dutch-processed cocoa for a smoother taste. Cornstarch (1 tbsp) – Contributes to the texture; can be omitted but will alter consistency. Salt (1/4 tsp) – Balances sweetness and enhances flavor; important for perfecting taste. Semi-sweet chocolate chips (1/2 cup) + Milk chocolate chips (1/2 cup) – Adds pockets of chocolate throughout; substitute with dark chocolate chips for more intensity. For the Monster Cookie Topping All-purpose flour (1/2 cup) – Provides structure for the cookie dough; can also be substituted for a gluten-free alternative. Peanut butter (1/4 cup) – Adds richness and flavor; substitute with almond butter for a unique twist. Quick oats (1/2 cup) – Gives texture to cookie dough and is vital for a chewy consistency. Mini chocolate chips (1/2 cup) – Allows for delightful chocolate bursts in each bite; can be swapped with butterscotch chips for a different flavor experience. Mini M&M’s (1/2 cup) – Adds crunchy pops of candy; perfect to enhance the colorful appeal of the Monster Cookie Fudgy Brownies. Step‑by‑Step Instructions for Monster Cookie Fudgy Brownies Step 1: Prepare Monster Cookie Dough In a medium bowl, whisk together 1/2 cup of flour, 1 tablespoon of cornstarch, 1/2 teaspoon of baking soda, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt until well combined. In a separate large bowl, beat 5 tablespoons of softened butter, 1/4 cup of brown sugar, and 1/2 cup of white sugar until light and fluffy, about 2-3 minutes. Mix in 1/4 cup of peanut butter, 1 teaspoon of vanilla, and 2 large eggs until smooth. Gradually fold in the dry ingredients, then stir in 1/2 cup of quick oats, 1/2 cup of mini chocolate chips, and 1/2 cup of mini M&M’s. Chill the dough in the refrigerator for 40 minutes. Step 2: Prepare Brownie Batter Preheat your oven to 325°F (163°C). Grease a 9×9 inch pan and line it with parchment paper for easy removal. In a medium bowl, sift together 1/2 cup of flour, 3/4 cup of cocoa powder, 1 tablespoon of cornstarch, and 1/4 teaspoon of salt, then set aside. In a large mixing bowl, beat together 1 cup of sugar and 2 eggs until the mixture is light and fluffy, about 5 minutes. Add in 1/4 cup of melted butter, 1/3 cup of oil, and 1 teaspoon of vanilla extract, mixing until well combined. Carefully fold in the dry ingredients, then incorporate 1/2 cup of semi-sweet chocolate chips. Pour the batter into the prepared pan and spread evenly. Step 3: Combine & Bake Place the brownie batter in the preheated oven and bake for 15 minutes, or until the edges are slightly set. While the brownies are baking, flatten the chilled monster cookie dough into discs using your hands. After 15 minutes, remove the brownies from the oven and evenly distribute the cookie dough on top, pressing it gently to create an even layer. Return the pan to the oven and bake for an additional 20-25 minutes, or until the cookie layer is golden and set. Cover with foil if the top is browning too quickly. Step 4: Cool and Serve Once baked, take the pan out of the oven and allow the Monster Cookie Fudgy Brownies to cool completely in the pan. This cooling period, which should take at least 1 hour, helps enhance the flavors and makes cutting easier. After they are cool, lift the brownies from the pan using the parchment paper and slice into squares. Enjoy your delightful indulgence!

Make Ahead Options These Monster Cookie Fudgy Brownies are perfect for busy home cooks looking to save time in the kitchen! You can prepare the monster cookie dough up to 24 hours in advance by mixing the ingredients and chilling it in the refrigerator, which helps enhance the flavors.

How to Store and Freeze Monster Cookie Fudgy Brownies Fridge: Store your Monster Cookie Fudgy Brownies in an airtight container in the fridge for up to 5 days.

Thaw them in the fridge overnight before serving. Room Temperature: You can also keep brownies at room temperature in a sealed container for 2-3 days, but they may dry out quicker without refrigeration.

Monster Cookie Fudgy Brownies Recipe FAQs How do I choose the right ingredients for the Monster Cookie Fudgy Brownies? Absolutely! For the best results, select ripe, high-quality ingredients. For the chocolate, opt for semi-sweet and milk chocolate chips—this combo enhances the flavor and texture. Ensure eggs are at room temperature before mixing, as this helps them incorporate better into the batter. How should I store the Monster Cookie Fudgy Brownies? You can store your Monster Cookie Fudgy Brownies in an airtight container in the refrigerator for up to 5 days. If you prefer them at room temperature, keep them sealed at room temperature for 2-3 days. Just note that they may dry out more quickly without refrigeration. Remember, the fresher, the better! Can I freeze Monster Cookie Fudgy Brownies? Yes, you can absolutely freeze these brownies to enjoy them later! After they’ve cooled, wrap the Monster Cookie Fudgy Brownies tightly in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 2 months. To enjoy, thaw them in the fridge overnight before serving. How can I troubleshoot if my brownies turned out dry? If your brownies came out dry, it might be due to too much flour in the mix. Always ensure you are measuring your flour correctly—lightly spooning it into a measuring cup and leveling it off is key. Also, overbaking can lead to dryness, so keep an eye on the timer during the last few minutes of baking. Are there any dietary considerations I should be aware of? Yes, good point! If you or anyone you’re serving has nut allergies, I recommend substituting the peanut butter with sunflower seed butter or cookie butter. Also, for gluten-free options, simply swap out the all-purpose flour for almond flour. Always double-check all ingredients for allergens, especially if serving to guests!
