How to Make Colorful Halloween Monster Cookie Brownies
-
Preheat your oven to 350°F (177°C) and grease a 9″x13″ baking pan with nonstick spray. For extra insurance against sticking, line the bottom with parchment paper.
-
Prepare brownie batter: Grab your brownie mix and follow the instructions on the box. Pour that rich, fudgy batter into the prepared pan, and don’t forget to lick the spoon—it’s a rite of passage!
-
Make the cookie layer: In a stand mixer, cream together the smooth peanut butter and unsalted butter until smooth. Add in light brown sugar, granulated sugar, eggs, and vanilla extract; mix until everything is light, fluffy, and inviting.
-
Combine dry ingredients: In a separate bowl, whisk together all-purpose flour, baking soda, and kosher salt. Gently stir in quick oats and mini chocolate chips, mixing just until combined. You want those dry ingredients to disappear without overmixing!
-
Assemble: Spoon dollops of the cookie layer over your brownie mixture, creating a fun swirl. Finish with a sprinkle of Halloween-themed sprinkles and large candy eyes to bring your spooky creations to life.
-
Bake for 25-27 minutes! Insert a toothpick in the center, and it should come out clean or with a few moist crumbs—nothing more!
-
Cool for 30 minutes in the pan, then carefully lift the brownies out using the parchment paper. Allow them to cool completely on a wire rack to set that amazing texture.
-
Make frosting: In a mixing bowl, beat together room-temperature butter, powdered sugar, vanilla extract, and heavy cream until it’s thick and creamy. Add in neon green gel food coloring, mixing until your frosting reaches that perfect spooky hue.
-
Decorate: Time to get creative! Pipe the frosting onto your cooled brownies, placing those adorable candy eyes into each dollop. Let the frosting set before cutting into squares.
Optional: Add some raspberry or strawberry sauce for a delicious drizzle over the top!

Make Ahead Options
These Colorful Halloween Monster Cookie Brownies are perfect for busy weeknights and any family festivities! You can prepare the brownie base and the cookie layer up to 24 hours in advance. Simply make your brownie batter and spread it in the pan, then refrigerate, covered with plastic wrap. Prepare the cookie layer separately and keep it in the refrigerator, too. When you’re ready to bake, just spread the cookie layer on top and bake as instructed. To preserve texture, avoid freezing, and ensure everything is at room temperature before baking for just as delicious results. This way, you’ll have a fun, spooky treat ready to impress with minimal effort!

Colorful Halloween Monster Cookie Brownies Recipe FAQs
What kind of brownie mix works best for the Colorful Halloween Monster Cookie Brownies?
Absolutely! A standard 18.3 oz box of fudgy brownie mix will yield the richest flavor and texture. If you prefer a lighter brownie, you can opt for a cake mix, but I recommend fudgy mixes for that perfect gooey base!
How should I store leftover Colorful Halloween Monster Cookie Brownies?
To keep these delightful brownies fresh, store them in an airtight container at room temperature for up to 5 days. If you want them to last longer, you can refrigerate them for a week. Just allow them to come to room temperature before serving to maintain their texture and flavor.
Can I freeze Colorful Halloween Monster Cookie Brownies?
Yes, you can freeze these brownies for up to 3 months! To freeze, layer them between sheets of parchment paper in an airtight container. Simply thaw overnight in the fridge when you’re ready to indulge. You can also reheat individual squares in the microwave for about 10-15 seconds for a fresh-from-the-oven feel.
What should I do if my brownies turn out too dry?
Nobody wants dry brownies! If that happens, it might be due to overbaking. Make sure to start checking for doneness a few minutes before the recommended baking time. The toothpick test is your friend—look for a clean pick or a few moist crumbs for the perfect gooey texture. If they are dry, serve them warm with ice cream or drizzle with warm chocolate sauce to add back some moisture.
Are Colorful Halloween Monster Cookie Brownies suitable for vegans?
You can easily make these brownies vegan by substituting the eggs for flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water equals one egg). You can also use a plant-based butter alternative and ensure your brownie mix is vegan-friendly!
How can I decorate the Colorful Halloween Monster Cookie Brownies for a party?
Get creative! Use Halloween-themed sprinkles, mini candy bats, or even drizzle with colorful icing. You can also place gummy worms or chocolate spider candies on top to enhance the spooky theme. The more, the merrier!
