Step‑by‑Step Instructions for Halloween Brookies
Step 1: Preheat the Oven
Begin your Halloween Brookies by preheating your oven to 350 °F. This ensures that your treats will bake evenly, creating that perfect fudgy texture. While the oven warms up, gather your ingredients and grease a 9 x 13-inch baking pan with cooking spray or butter, preparing for the festive baking adventure ahead.
Step 2: Prepare the Brownie Batter
In a large mixing bowl, prepare the store-bought brownie mix according to the package instructions, usually by adding water, oil, and eggs. Stir until you have a smooth, rich batter—about 2 minutes of mixing. This step not only establishes the base of your Halloween Brookies but also fills your kitchen with a delightful aroma of chocolate.
Step 3: Add the M&M's to the Batter
Once the brownie batter is mixed, fold in ¼ cup of Halloween M&M's, allowing their vibrant colors to blend into the rich chocolate. This adds a fun crunch and sweetness to the fudgy brownies. Ensure the M&M's are evenly distributed for a delightful surprise in every bite.
Step 4: Spread the Brownie Batter
Pour the brownie batter into your greased baking pan, using a spatula to spread it evenly across the bottom. Ensure that it reaches the corners for uniform baking. You'll want a smooth top so that the spooky cookie layer can sit perfectly atop it—this is the base of your delicious Halloween Brookies.
Step 5: Add More M&M's
Sprinkle an additional handful of Halloween M&M's on top of the brownie batter. This not only gives a festive look but also adds extra chocolatey bits to each bite. The colorful candies will create a beautiful contrast against the dark brownie base, bringing in that playful Halloween spirit.
Step 6: Place the Sugar Cookies
Now, take 15 pieces of the Pillsbury ghost-shaped sugar cookie dough and evenly place them on top of the brownie batter. Space them out to allow for some spreading during baking. This whimsical addition transforms your brownies into Halloween Brookies, combining the best of both worlds in one delicious dessert.
Step 7: Bake to Perfection
Slide the baking pan into your preheated oven and bake for 28-30 minutes. Keep an eye on the edges, which will become slightly crispy, while the center remains fudgy. When a toothpick inserted in the center comes out with just a few crumbs, remove your Halloween Brookies from the oven to finish baking.
Step 8: Cool and Serve
Once baked, allow your Halloween Brookies to cool in the pan for at least 15 minutes. This resting time helps them set up perfectly, making for easier slicing. When ready, cut them into squares, and enjoy the delightful blend of brownie and cookie as you celebrate this spooky season!

Expert Tips for Halloween Brookies
-
Check the Batter: Make sure to mix the brownie batter just until combined, avoiding overmixing, which can result in dense brownies instead of fudginess.
-
Cookie Placement: Space out the ghost-shaped cookies on the brownie base to allow for spreading; this will help maintain the cookie shape while baking.
-
Monitor Baking Time: Keep an eye on the brookies as they bake, checking them at the 25-minute mark to avoid over-baking. A toothpick should come out with a few crumbs for the perfect fudgy texture.
-
Cool Before Cutting: Allow the Halloween Brookies to cool for at least 15 minutes in the pan before cutting. This helps them set, making them easier to slice into perfect squares.
-
Experiment with Mix-ins: Feel free to add nuts or different types of candy to the brownie batter for added texture and fun variations—creativity is key!
Make Ahead Options
These Halloween Brookies are perfect for meal prep enthusiasts, saving you time on busy weeknights! You can prepare the brownie batter and refrigerate it for up to 24 hours before baking.

You can also place the ghost-shaped sugar cookies on top of the brownie batter up to 3 days in advance—just ensure you refrigerate them as well.

Halloween Brookies Recipe FAQs
What type of brownie mix should I use?

How should I store leftover Halloween Brookies?
To keep your Halloween Brookies fresh and tasty, store them in an airtight container at room temperature for up to 3 days. If you prefer them a bit colder, you can also refrigerate them for up to a week. Just remember to bring them back to room temperature before enjoying for the best flavor!
Can I freeze Halloween Brookies?

What if my brownie edges are too crispy?
Very! If you find the edges of your Halloween Brookies are getting too crispy, it's likely a sign they’ve been in the oven a little too long.

Are Halloween Brookies safe for pets?
