Halloween Brookies are the answer to all those “what spooky treat should I bring?” moments in October.

I promise, they’ll fly off the plate faster than you can say “trick or treat.” Trust me, baking these will make you the MVP of any Halloween shindig. You can peek at more awesome Halloween recipes if your baking list is looking a bit empty.

What is a brookie?

So here’s the scoop. A brookie isn’t some cryptic baking code, it’s just pure magic. It’s a half brownie, half cookie bar. You swirl fudgy brownie batter with classic chocolate chip cookie dough and bake ’em up in one pan. Brownie + cookie = brookie. Get it?

My family absolutely devours these. There’s just something about that gooey, chewy, chocolatey vibe that ticks extra boxes. And for Halloween, I throw in candies (think M&Ms, Halloween sprinkles, you name it). The end result? Looks impressive. Tastes even better. And let’s be honest, nobody is ever mad about two desserts mashed into one sticky square.

Ingredient	Quantity	Notes
Brownie Mix	1 box	Opt for your favorite brand for a quick recipe!
Chocolate Chip Cookies	1 batch	Use your go-to recipe or premade dough.
Halloween Sprinkles	1 cup	For that festive touch on top!
Eggs	2	Room temperature for best results.
Butter	½ cup (1 stick)	Melted for the brownie mix.

How to make Halloween brookies

Let me walk you through this. You don’t need a fancy stand mixer or anything wild. Just a bowl, a hand mixer (or some elbow grease), and your best spooky spirit.

First, preheat your oven to 350°F. Grease a 9×13-inch pan. That’s your stage.

Mix up some brownie batter (I go with a simple chocolatey recipe, honestly any brownie box mix works if you’re in a hurry). Pour that into the pan. Hold up…don’t bake it yet.

Now, whip up your favorite chocolate chip cookie dough (again, chilling your dough helps but don’t sweat it if you’re in a rush).

Drop scoops of cookie dough right onto the unbaked brownie batter. Lightly swirl with a knife. Don’t overmix.

Scatter Halloween candies or sprinkles on top. Pop it in the oven for 30–35 minutes, until it’s just set and shimmery.

Cool (as hard as that is), then slice up those Halloween brookies and try not to eat the whole pan yourself. If you want a full list of toppings? I’m kinda obsessed with the ideas over in the Halloween recipes roundup too.

Tips for baking soft and fudgy brookies

Getting that just-right chewy center is a life goal, right? Here’s how I make mine next-level:

• Never overbake. Seriously, take ’em out when the center looks slightly wobbly.
• Use room temperature ingredients. Makes everything blend nicer.
• Chill your cookie dough for like 20 minutes if you’ve got time. Huge flavor difference.
• Let them cool totally before cutting. I mess this up all the time but it really helps them set up honestly.

Boom. You’ll get Halloween brookies with perfect fudgy-brownie meets chewy-cookie texture. Honestly, it’s like a five-star restaurant in your own kitchen.

Can this recipe be made gluten free?

Big yes on this one. I’ve done it a few times for party guests who need gluten free treats, nobody even noticed. Here’s how I swap it:

I use a solid 1:1 gluten free flour blend for both the brownie and cookie layers. Bob’s Red Mill or King Arthur both work well. Sometimes I toss in an extra egg yolk to help them stay moist. You still get the same chewy, gooey middle and crisp edges without any weird aftertaste. Just peek at your add-ins (make sure your chocolate chips and candy toppings are gluten free too). I recommend testing a small batch first if you’re nervous, but honestly, Halloween brookies are super forgiving for swaps like this.

Alternative cookie bar decorations

Halloween brookies are a blank canvas. There’s a ton of ways to decorate ’em for spooky season fun:

Go for classic orange, black, and purple sprinkles. Add candy eyeballs for a monster-vibe. If you want extra crunch, toss in pretzel sticks or candy corn before baking. Swirl a bit of orange and black food dye through the cookie or brownie batter before baking for wild color swirls. And don’t feel boxed in, swap in peanut butter chips, chopped Oreos, or toffee bits. If you peek at some Halloween cookie bar ideas, the possibilities are endless.

Honestly, the messier the better in my opinion.
