Oreo layered Halloween brownies are the showstopper treat you want for fall gatherings or spooky parties. Each slice reveals a bright orange center from those eye-catching Halloween Oreos plus two layers of rich frosting. Kids and grownups both love the dramatic look but even more the fudgy bite and creamy finish.
This was the first thing my daughter asked to bake with me for her Halloween party and every year since it makes our table look memorable and festive
Ingredients
- Brownie mix: Choose your favorite fudgy boxed mix and aim for a brand that says rich or chocolate lover for the deepest flavor
- Eggs: These give structure and richness so use large eggs at room temperature for best results
- Oil: Mild flavored like canola or vegetable keeps brownies soft and moist
- Milk: Adds extra moisture and an ultra gooey crumb
- Oreos with orange filling: Seek out the seasonal Halloween pack with the vivid orange cream for ultimate color pop a classic chocolate cookie always brings that crunch
- Milk chocolate frosting: A can of creamy milk chocolate frosting means easy spreading and extra decadence
- White or vanilla frosting: You will tint this so go for a simple flavor with a snowy base
- Orange food coloring gel: For bold color spend a bit more for gel type so your frosting is vivid not pale
Instructions
- Prep the pan:
- Line a nine by nine inch pan with parchment paper pressing it into corners so brownies lift out cleanly later
- Mix the brownie batter:
- In a large bowl combine brownie mix eggs oil and milk stirring until just smooth and creamy with no dry patches
- Layer in Oreos:
- Pour the brownie batter into your pan then gently press Oreo cookies into the top of the batter spacing them evenly so you get a cookie in each piece
- Bake to perfection:
- Place in the oven and bake for twenty five to thirty minutes just until a toothpick comes out with a few moist crumbs Be careful not to overbake so brownies stay fudgy Let cool completely
- Make the orange frosting center:
- Place white frosting into a bowl Add the orange centers scraped from about ten Oreos plus a spoonful of orange gel food coloring Mix very well until color is vivid and frosting is smooth
- Frost with orange layer and chill:
- Spread the orange frosting evenly over your cooled brownies getting the frosting right to the edges Place in the fridge for thirty minutes to help it set and make layering easier
- Top with chocolate frosting and more Oreos:
- Remove brownies from the fridge Gently spread milk chocolate frosting over the orange layer For crunch and decoration crumble the rest of your Oreos over the top
- Cut and serve:
- Once the brownies are fully set use a knife to cut them into even squares cleaning your blade between slices for neat layers Serve at room temperature for best gooey texture

My favorite thing about these brownies is the punch of orange tucked inside each bar It always makes people ask how you did it and reminds me of making kid friendly desserts that still impress adults My son likes to sneak extra crumbled Oreos onto his piece and it is now our family tradition
Storage Tips
Store any leftover brownies in an airtight container at room temperature for up to four days If your kitchen is warm pop them in the fridge and let them come to room temp before serving
Ingredient Substitutions

Success Stories
Last Halloween a neighbor messaged me the next morning saying her family ate the entire plate overnight She now requests them for every school party I have learned to save a square before they vanish
Freezer Meal Conversion
