For the Cookie Topping
- Premade Halloween Cookie Dough – These adorable ghost or pumpkin-shaped cookies simplify the process while adding a festive flair; using ready-made dough saves time during the holiday rush.

Step‑by‑Step Instructions for Halloween Brookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step ensures that your Halloween Brookies bake evenly and rise perfectly. While the oven heats, gather your ingredients and greasing supplies, preparing to create a deliciously trick-or-treat-worthy dessert.
Step 2: Prepare the Brownie Mix
In a mixing bowl, prepare the brownie mix according to the package directions, typically combining it with water, oil, and eggs. Stir gently to mix the ingredients, taking care not to overmix. This will help achieve a dense, fudgy texture for your brookies—a perfect base for the flavors to come!
Step 3: Fold in M&M’s
Once your brownie batter is smooth, fold in 1/4 cup of Halloween M&M’s, adding a pop of color to your mix. This extra step not only enhances the flavor but also adds a delightful crunch to each bite. Make sure the candies are well-distributed, ensuring that every piece offers a spooky surprise!
Step 4: Pour the Batter into the Pan
Grease a 9×13 inch baking dish thoroughly using butter or non-stick spray to prevent sticking. Pour the chocolate brownie batter evenly into the prepared dish, using a spatula to spread it out smoothly. This creates the perfect foundation for your Halloween Brookies, promising a rich and gooey outcome.
Step 5: Add Cookie Dough Topping
Take your premade Halloween cookie dough and break it into small pieces. Evenly distribute the dough pieces on top of the brownie batter. This method prevents the cookie dough from spreading too much during baking, maintaining its adorable shape while creating a delicious cookie layer atop the brownies.
Step 6: Bake Until Perfect
Carefully place the baking dish in the oven and bake for 28-30 minutes. Keep an eye on them! You’ll know they’re done when a toothpick inserted into the center comes out with a few moist crumbs. Adjust the baking time as needed, tossing in a couple of extra minutes if things aren’t quite there yet.
Step 7: Cool and Decorate
Allow the brookies to cool completely in the pan on a wire rack, which helps them set properly. If any M&M’s have sunk into the batter, now’s the time to sprinkle some more on top to add a festive touch. Once cooled, slice them into squares, presenting a perfect Halloween treat to share with family and friends!

Halloween Brookies Recipe FAQs
How can I ensure my brownie mix is the right texture?
Absolutely! When preparing your brownie mix, avoid overmixing the batter. Gently combine the ingredients until just blended; this will help retain a fudgy texture instead of ending up with fluffy brownies. Remember, the goal is to stir until there are no large lumps but still keep it thick.
What’s the best way to store leftover Halloween Brookies?
To keep your Halloween Brookies fresh, store them in an airtight container at room temperature for up to 3 days. If you want to extend their life, refrigerate them for up to a week. Just be sure the container is sealed tightly to maintain that delicious chewy texture!
Can I freeze Halloween Brookies, and if so, how?
Absolutely! To freeze your Halloween Brookies, individually wrap each piece in plastic wrap and then place them in a freezer-safe bag. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy them, simply thaw in the fridge overnight and warm them in the microwave for about 10-15 seconds for that freshly baked feel.
What if my Halloween M&M’s sink to the bottom?
Very good question! If you notice that your M&M’s sink while baking, don’t worry. Just sprinkle some additional candies on top right after baking before they cool—this adds a decorative touch! For future batches, you can also try tossing the M&M’s in a bit of flour before folding them into the batter; this helps them stay suspended during baking.
Is there a way to make Halloween Brookies pet-friendly?
While it’s tempting to share, chocolate is toxic for pets, so it’s best to keep Halloween Brookies away from them. For a pet-safe treat, consider creating a special batch using carob chips instead of chocolate, along with pet-safe ingredients. Always consult your vet before introducing new foods to your furry friends.
What if I can’t find Halloween-themed cookie dough?
No worries! If you can’t locate premade Halloween cookie dough, feel free to substitute with any flavored cookie dough you prefer, such as chocolate chip or peanut butter cookie dough. Just be sure the dough is ready-to-bake so you can keep the process quick and easy. The more the merrier when it comes to flavors!
