INGREDIENTS

  • 1 Brownie Mix: Forms your fudgy foundation with deep chocolate goodness.
  • 2 eggs: Works as the glue for your mixture while adding a richer texture.
  • 1/3 cup oil: Gives your brownies that can't-resist softness.
  • 1/3 cup milk: Makes everything wetter and helps your batter mix smoothly.
  • 1 Package of Oreo's (with orange filling): Brings the Halloween spirit and that satisfying cookie crunch.
  • 1 can of Milk chocolate frosting: Tops everything off with sweet, creamy chocolate goodness.
  • 1 can of White or Vanilla frosting: Becomes your bright orange middle layer.
  • Orange food coloring gel: Turns your vanilla frosting into a Halloween showstopper.

INSTRUCTIONS

Step 1:
Heat your oven to 350°F and put parchment paper in a 9x9 inch baking dish.
Step 2:
Grab your stand mixer and throw in the Brownie mix, eggs, oil, and milk. Mix with the whisk on medium until everything's smooth.
Step 3:
Pour your brownie goop into the lined pan, making it flat. Then place Oreos all over the top so they cover everything.
Step 4:
Stick the pan in the oven for 25 to 30 minutes. You'll know they're done when you poke a toothpick in and it comes out clean. Let them cool completely right in the pan.
Step 5:
While cooling happens, make your orange frosting. Mix the white/vanilla frosting with about 10 Oreo centers (the orange part). Add a teaspoon of orange gel coloring and stir until you've got a bright pumpkin shade.
Step 6:
Once brownies aren't warm anymore, spread your orange frosting all over. Stick the pan in the fridge for about 30 minutes to firm up.
Step 7:
Take your chilled brownies out and cover the orange layer with milk chocolate frosting. Crush leftover Oreos and sprinkle the pieces on top.
Step 8:
Cut them into 3x2 inch squares and dig in right away. Enjoy all those yummy, sticky layers!

Serving and Storage Tips

  • These taste amazing when they're a bit cold - it keeps the frosting layers from getting messy, but room temp works too if you like them softer.
  • Want to impress your guests? Cut them tiny and arrange them on a spooky Halloween plate.
  • Got leftovers? Pop them in an airtight container in your fridge for up to 3 days. You can even freeze them for up to 2 months - just let them thaw in the fridge before eating.

Tips from Well-Known Chefs

  • Duff Goldman always uses parchment paper so you can just lift the whole thing out without making a mess.
  • Christina Tosi says to chill your brownies before cutting - you'll get cleaner edges that way.

VARIATIONS

  • Try using the peanut butter Oreos or smear some peanut butter between your brownie base and cookie layer.
  • Want them super melty? Toss chocolate chips into your brownie mix before baking.
  • You can change the frosting colors completely - try red and green for Christmas time instead.
