Halloween Brookies are my go-to when a busy week calls for something chocolatey and festive. I pull them together in under an hour, and they slice cleanly for quick serving. The brownies stay fudgy, the cookie layer chewy, and the Halloween M&M’s give just the right color pop. Best of all, they’re easily customizable—swap sprinkles or toppings, or add a drizzle—so they fit every party vibe without extra stress.

Quick, crowd-pleasing, and easily customizable

I love how these brookies come together with everyday ingredients. One pan, in about 38 minutes, and you’ve got party-worthy bars. They’re forgiving too—swap flavors, swap toppings, or choose gluten-free brownie mix for dietary needs.

Ingredients Halloween Brookies

I keep these ingredients on hand for quick Halloween fun. Exact quantities are listed at the bottom and printable, so you can shop once and bake on the fly.

Brownie base

• 1 box brownie mix (plus eggs, oil, and water as directed) — this is the fudgy foundation I rely on for deep chocolate flavor.

Cookie layer

• 1 1/2 cups chocolate chip cookie dough (homemade or store-bought) — I prefer soft dough that bakes chewy and holds shape.

Festive add-ins

• 1/2 cup Halloween M&M’s or candy-coated chocolates — adds color and crunch; choose peanut-free if needed.
• 1/4 cup Halloween sprinkles — a sparkly Halloween touch without overpowering the bite.

Optional tips (substitutions)

• Gluten-free or dairy-free variants — use gluten-free brownie mix and a dairy-free oil or butter substitute.
• Extra toppings ideas — swap M&M’s for candy eyeballs, caramel bits, pretzel pieces, or toasted coconut for different vibes.

How to Make Halloween Brookies

Making Halloween Brookies is the perfect quick project for a busy day. I layer fudgy brownie base with chewy cookie dough, then crown them with Halloween sprinkles and M&M’s for a festive bite.

Step 1 — Prep and preheat

I preheat the oven to 350°F (175°C). I line a 9×13-inch pan with parchment paper so the bars lift out cleanly. This small prep saves a lot of mess later.

Step 2 — Brownie batter base

Prepare the brownie batter according to the package. Pour the batter into the prepared pan and spread it evenly with a spatula. The brownie layer gives Halloween Brookies their fudgy, dark canvas.

Step 3 — Layer the cookie dough

Dollop the cookie dough across the brownie surface in uneven circles. Press the dough down gently so it nests into the brownie layer. This creates the signature burrowed-cookie effect in every bite.

Step 4 — Add festive toppings

Sprinkle Halloween M&M’s and Halloween sprinkles over the top. A light press helps the toppings adhere as the bars bake. The colors sparkle like tiny party lights on a tray.

Step 5 — Bake and test doneness

Bake at 350°F for 28–30 minutes. The center should be set with a few moist crumbs on a toothpick. If it looks too glossy, give it a few more minutes, then test again.

Step 6 — Cool, slice, and serve

Let the pan cool completely before slicing. Lift the slab out with the parchment margins for clean cuts. Slice into bars and arrange on a platter for a spooky, crowd-pleasing display.

Tips for Success

These quick reminders keep your Halloween Brookies bake smooth, especially when you’re juggling tasks. A little prep and patience go a long way toward clean cuts and happy eaters. Think ahead: gather toppings, pans, and a timer before you start.

General tips

• Use parchment-lined 9×13-inch pan for easy release
• Don’t overbake; center should be just set
• Let cool completely before slicing for clean edges
• Press cookie dough gently to embed into the brownie layer

Equipment Needed

I keep these tools within reach so Halloween Brookies bake quickly and cleanly. A few dependable gadgets make busy days feel doable.

Essential tools

Variations

Flavor and dietary tweaks

Serving Suggestions

Party-ready ideas
