Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C). Line a 9 × 9-inch baking pan with parchment paper or lightly grease it.
Step 2: Make the Brownie Batter
In a mixing bowl, combine the brownie mix, eggs, oil, and milk. Stir until smooth and fully blended.
Step 3: Add Oreo Layer
Pour the brownie batter into the prepared pan. Arrange the Oreos (orange‑filled) on top, pressing them gently into the batter.
Step 4: Bake
Bake for 25–30 minutes or until a toothpick inserted in the center comes out clean. Allow brownies to cool completely before frosting.
Step 5: Prepare Orange Frosting
Mix white or vanilla frosting with the orange filling of about 10 Oreos. Add 1 teaspoon of orange food coloring gel for extra vibrancy. Stir until smooth.
Step 6: Frost & Chill
Once brownies are cooled, spread the orange frosting evenly over the top. Chill in the refrigerator for about 30 minutes to help set the frosting.
Step 7: Top with Chocolate & Crumble
Spread milk chocolate frosting over the set orange layer. Crumble remaining Oreos and scatter on top. Let set briefly, then slice.
Step 8: Serve
Cut the brownies into 3 × 2‑inch squares. Serve and enjoy the layered surprise in every bite.

FAQs
Can I use plain Oreos (no orange filling)?
Yes — but you’ll lose the hidden orange surprise. Use more food coloring to get the festive look.
