Ingredients You’ll Need
These ingredients are simple pantry staples, yet each plays a crucial role in creating the luscious texture and decadent flavor of your Monster Cookie Fudgy Brownies. From the richness of butter and eggs to the boldness of Dutch-processed cocoa, every component works together to deliver that irresistible fudgy bite.
- 1 1/3 cup White granulated sugar: Adds sweetness and helps create a crisp crust on top.
- 2 Large eggs: Provide structure and moisture, ensuring the brownies stay tender.
- 1 Egg yolk: Enhances richness and contributes to a fudgy texture.
- 5 TBSP Unsalted butter: Gives a creamy depth and smooth mouthfeel.
- 1/3 cup Oil (canola or vegetable): Boosts moisture and keeps brownies soft and chewy.
- 1 tsp Pure vanilla extract: Infuses a warm, aromatic note that brightens the chocolate.
- 1/2 cup All-purpose flour: Provides just enough structure without drying out the brownies.
- 3/4 cup Unsweetened cocoa powder (Dutch process): Delivers intense chocolate flavor and a deep dark color.
How to Make Monster Cookie Fudgy Brownies
Step 1: Melt and Mix the Fats
Begin by gently melting the unsalted butter over low heat until smooth. Once melted, stir in the oil to combine their luscious fats that will make your brownies ultra-moist. This perfect fat blend is the secret to the fudgy texture everyone craves.
Step 2: Whisk Sugar and Eggs Together
In a separate bowl, vigorously whisk the white granulated sugar, eggs, and egg yolk. This creates a light, airy base that helps your brownies achieve a tender crumb. The eggs bind everything perfectly, ensuring every bite holds together without being cakey.
Step 3: Combine Wet Ingredients
Slowly pour the melted butter and oil mixture into your sugar and egg bowl, continuing to whisk steadily. Add the vanilla extract to infuse a rich warmth that balances the chocolate. This combined batter is where flavors start to meld beautifully.
Step 4: Sift and Fold in Dry Ingredients
Take your all-purpose flour and Dutch-processed cocoa powder, sift them together to avoid lumps, then gently fold them into your wet mixture. This careful folding ensures your brownies remain dense and fudgy instead of fluffy. Patience here makes all the difference!
Step 5: Bake to Perfection
Pour the batter into a greased or parchment-lined pan, spreading evenly. Bake in a preheated oven until the edges are set but the center is still slightly soft. This timing guarantees a perfect fudgy center with a slightly crisp top, the hallmark of your Monster Cookie Fudgy Brownies.
How to Serve Monster Cookie Fudgy Brownies

Garnishes
Sprinkle a handful of colorful chocolate candies or mini chocolate chips on top while the brownies are still warm. The slight melt adds a festive touch and brings in that classic monster cookie vibe. A light dusting of powdered sugar or a drizzle of caramel sauce also pairs wonderfully.
Side Dishes
Serve your brownies alongside a scoop of vanilla ice cream for a timeless duo. Fresh berries or a dollop of whipped cream can also elevate the dessert experience, balancing the rich chocolate with hints of freshness and lightness.
Creative Ways to Present
Cut the Monster Cookie Fudgy Brownies into bite-sized squares and thread them onto skewers with chunks of marshmallows and strawberries for a fun dessert kabob. Alternatively, layer crumbled brownies into parfait glasses with layers of pudding and cookie crumbs for a show-stopping treat.
Make Ahead and Storage
Storing Leftovers
Once cooled, store your Monster Cookie Fudgy Brownies in an airtight container at room temperature. They’ll stay perfectly fudgy for up to four days, making them an ideal make-ahead dessert that’s ready when you need a sweet pick-me-up.
Freezing
For longer storage, wrap individual brownie portions tightly in plastic wrap and place them in a freezer-safe container or bag. Frozen brownies remain delicious for up to three months and thaw beautifully without losing their fudgy charm.
Reheating
To enjoy freshly warmed Monster Cookie Fudgy Brownies, microwave for 15 to 20 seconds or warm in a low oven. This brings back that soft, melty texture as if they just came out of the oven, making each bite pure bliss.
FAQs
Can I use regular cocoa powder instead of Dutch process?
Yes, you can substitute regular cocoa powder, but the flavor will be slightly less mellow and the color a bit less vibrant. Dutch-processed cocoa offers a richer, smoother chocolate taste that really enhances this recipe.
Are these brownies gluten-free?
This recipe calls for all-purpose flour, which contains gluten. To make it gluten-free, you can try using a gluten-free flour blend, but be mindful the texture may shift slightly.
Can I add mix-ins like nuts or chocolate chips?
Absolutely! Adding chopped walnuts, pecans, or chocolate chips will boost texture and flavor, making your Monster Cookie Fudgy Brownies even more indulgent and personalized.
What’s the best pan size for baking these brownies?
A 9×9 inch square pan works perfectly, allowing the brownies to bake evenly with the ideal thickness. Using a larger pan might result in thinner brownies that bake too quickly.
How do I know when my brownies are done?
Look for set edges and a slightly soft center that still jiggles a bit when you gently shake the pan. Overbaking will dry out the brownies, so err on the side of slightly underdone for that perfect fudgy texture.
Final Thoughts
These Monster Cookie Fudgy Brownies are pure magic in dessert form. They combine simple ingredients and straightforward steps to create an unforgettable treat that feels both nostalgic and totally irresistible. I can’t wait for you to make them and share this little slice of joy with your loved ones. Happy baking!

Ingredients
Wet Ingredients
- 5 tablespoons unsalted butter
- 1/3 cup oil (canola or vegetable)
- 1 teaspoon pure vanilla extract
- 2 large eggs
- 1 egg yolk
Dry Ingredients
- 1 1/3 cups white granulated sugar
- 1/2 cup all-purpose flour
- 3/4 cup unsweetened cocoa powder (Dutch process)
Additional Mix-ins
- 1 cup monster cookie mix (assorted colorful chocolate candies, pretzels, chocolate chips, and oatmeal cookie pieces)
Instructions
- Prepare Baking Pan: Preheat your oven to 350°F (175°C). Grease a 9×9 inch baking pan or line it with parchment paper to ensure easy removal of the brownies.
- Melt Butter: In a saucepan or microwave-safe bowl, melt the unsalted butter until just liquefied. Allow it to cool slightly.
- Combine Wet Ingredients: In a large bowl, whisk together the melted butter, oil, and vanilla extract. Add the eggs and egg yolk one at a time, beating well after each addition to achieve a smooth mixture.
- Add Sugar: Gradually stir in the white granulated sugar into the wet mixture until fully incorporated and smooth.
- Sift Dry Ingredients: In a separate bowl, sift together all-purpose flour and unsweetened cocoa powder to avoid lumps and ensure an even chocolate flavor.
- Mix Dry into Wet: Gently fold the dry ingredients into the wet mixture, mixing just until combined. Be careful not to over mix, which can cause tough brownies.
- Add Monster Cookie Mix: Carefully fold in your monster cookie mix (chocolate candies, pretzels, chocolate chips, and oatmeal cookies) to distribute them evenly throughout the batter.
- Pour and Spread: Pour the batter into the prepared baking pan and spread it evenly with a spatula.
- Bake: Bake in the preheated oven for 25-30 minutes. Check doneness by inserting a toothpick in the center; it should come out with a few moist crumbs for fudgy brownies.
- Cool and Serve: Allow the brownies to cool completely in the pan on a wire rack before cutting into squares to serve. This helps them set and enhances the fudgy texture.
Notes
- Use Dutch process cocoa for a richer, less acidic chocolate flavor.
- Consider chilling the batter for 15 minutes before baking to reduce spreading and improve texture.
- Substitute vegetable oil with melted coconut oil for a light coconut undertone.
- Store brownies in an airtight container at room temperature for up to 4 days, or freeze for longer storage.
- For extra gooey brownies, slightly underbake by a couple of minutes and let them cool completely.
