Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Preheat your oven to 350°F (175°C) and grease or line an 8×8-inch or 9×13-inch baking pan with parchment paper.
Prepare brownie batter according to the package instructions (or use your favorite homemade recipe).
Pour half of the brownie batter into the prepared pan and spread evenly.
Arrange a layer of Halloween Oreos over the batter.
Pour the remaining brownie batter on top and gently spread to cover the cookies.
Press a few extra Oreos on top and add Halloween sprinkles or candy eyeballs if using.
Bake according to brownie mix directions, typically 30–35 minutes for an 8×8 pan or 25–30 minutes for a 9×13 pan, or until a toothpick comes out with just a few moist crumbs.
Let cool completely before slicing.
Servings and timing
This recipe serves 9–12 people, depending on how you cut the brownies. Prep time is 10 minutes, and bake time is 30–35 minutes. Total time: approximately 45 minutes.
Variations
Peanut butter twist: Add peanut butter chips or swirl peanut butter into the batter.
Candy-loaded: Top with chopped Halloween candies like Reese’s, M&M’s, or Kit Kats.
Marshmallow topping: Add mini marshmallows during the last 5 minutes of baking for a gooey finish.

Storage/Reheating
Store Halloween Oreo brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days.
