Halloween Oreo Brownies come packed with chocolate goodness and a splash of bright color. You’ve got layers with holiday-themed Oreos, a bold orange middle, and a thick milk chocolate topping to finish it off. These brownies are perfect if you’re throwing a spooky get-together or just want a special fall treat. The mix of gooey chocolate, colorful frosting, and cookie crunch will stand out every time. Check out what you’ll need to whip them up.

INGREDIENTS

  • Orange food coloring gel: Brings a pop of festive Halloween color to your frosting.
  • 1 can of White or Vanilla frosting: This is what you'll tint orange for the bright layer in the middle.
  • 1 can of Milk chocolate frosting: Spread this rich layer over the top of your brownies.
  • 1 Package of Halloween Oreos (orange filling): Adds crunch and a bold look to every bite.
  • 1/3 cup milk: Makes the batter smooth and easy to pour.
  • 1/3 cup oil: Keeps things soft and moist after baking.
  • 2 eggs: These help everything hold together and make your brownies richer.
  • 1 Brownie Mix: Grab your favorite box—this is the chocolatey base for all the layers.

INSTRUCTIONS

Step 8:
Slice brownies into 3x2 inch pieces and dig in! Each bite hits that gooey, fudgy sweet spot.
Step 7:
Take brownies from the fridge and layer the milk chocolate frosting right on top. Sprinkle crumbled Oreos for a fun finish.
Step 6:
Chill the frosted brownies in the fridge for at least 30 minutes so the orange layer sets up nicely.
Step 5:
Mix your white (or vanilla) frosting with the orange filling from 10 Oreos in a bowl. Squirt in a teaspoon of orange gel and stir until it’s super vibrant.
Step 4:
Bake those brownies for about 25–30 minutes. Stick in a toothpick—if it’s clean, they’re ready! Let them cool all the way in the pan.
Step 3:
Smooth your brownie batter into the lined pan, then cover the top edge-to-edge with Oreos.
Step 2:
Toss together your brownie mix, eggs, oil, and milk in the mixer bowl. Blend on medium using the whisk attachment until it’s lump-free.
Step 1:
Set your oven to 350°F and pop parchment paper in a 9x9 pan so nothing sticks later.

Serving and Storage Tips

  • Want your brownies to hold those colorful layers? Stick 'em in the fridge—they’ll slice cleaner when cold. But room temp works if you like a softer bite.
  • Cutting them small and setting them out on a themed platter makes them a hit at parties.
  • Wrap up leftovers tight and stash in the fridge for 3 days. Or freeze for a couple months—just let them sit in the fridge overnight before you eat again.

Tips from Well-Known Chefs

  • Duff Goldman likes lining the pan with parchment, so you won’t wrestle with stuck brownies later.
  • Christina Tosi suggests chilling them for a bit—makes the frosted layers nice and firm and the slices super clean.

VARIATIONS

  • Craving peanut butter? Go with peanut butter Oreos or spread some peanut butter between layers before you bake.
  • Make 'em even more decadent—toss in handfuls of chocolate chips with the batter.
  • Color switch! Use red and green for a holiday treat or play with colors for any party theme.

Instructions

Step 01

Set your oven to 350°F and put parchment paper in a 9x9 pan.

Layer the top of the batter with Oreo cookies until the surface is covered.

Put the pan in the oven and bake for about 25-30 minutes. Use a toothpick to check—if it comes out clean, they're done.

Step 06

Let the baked brownies cool off completely before doing anything else.

Step 07

While waiting, mix the orange filling from about 10 Oreos with the white frosting. Add a teaspoon of the orange gel food color and mix well to create the desired shade.

Step 08

Spread the orange-tinted frosting over the cooled brownies, then chill in the fridge for at least 30 minutes.

After chilling, evenly cover the top with chocolate frosting. Crush up the leftover Oreos and sprinkle them on top.

Cut into squares, about 3x2 inches each, and enjoy them right away.
