Ingredients

• Brownie Mix: gives a thick fudgy base and saves time look for a brand with cocoa listed near the top
• Eggs: create lift and structure choose large eggs for best consistency
• Oil: keeps the brownies extra moist use neutral oil like canola or vegetable for best flavor
• Milk: smooths out the batter adding richness whole milk gives the most tender crumb
• Oreo Cookies with orange filling: add crunch and festive color check package dates for freshest cookies
• Milk Chocolate Frosting: adds a thick creamy layer over the brownies buy or make your favorite brand
• White or Vanilla Frosting: forms the base to create vibrant orange frosting check for a smooth and spreadable texture

Step-by-Step Instructions

Prep the Pan:

Line a 9 by 9 inch baking pan with parchment so your brownies come out easily and stay intact for layering later

Mix the Brownie Batter:

Combine brownie mix eggs oil and milk in a bowl Mix until no lumps remain and batter is glossy and thick This is your base layer and sets the brownies up for the right texture

Layer the Oreos:

Pour the batter into the lined pan Arrange whole Oreo cookies across the top Press them lightly into the batter so they are halfway submerged This helps them stay visible and gives the best layered effect

Bake the Brownies:

Bake at 350°F or 175°C for 25 to 30 minutes A toothpick inserted in the center should come out mostly clean Some crumbs are fine You want gooey not dry Let them cool completely so the frosting does not melt

Make the Orange Frosting:

While brownies cool scrape the orange filling out of about 10 Oreos and stir it into a can of white or vanilla frosting Add orange food coloring gel Mix until the color is even and vivid Adjust color to your liking

Frost the Brownies:

Once brownies are room temperature spread the orange frosting in an even layer Use an offset spatula for smoothness Place the pan in the fridge for 30 minutes so the frosting sets and does not mix into the next layer

Add Chocolate and Decorate:

When the orange layer is firm spread milk chocolate frosting over the top Crumble remaining Oreos with the orange centers and sprinkle over everything for extra crunch and a fun look

Cut and Serve:

Use a sharp knife to cut brownies into even 3 by 2 inch squares Serve chilled or at room temperature for the best flavor and definition between layers
