Peppermint Oreo Fudge Brownies with Cookie Dough

Decadent three-layer brownie combining refrigerated peppermint sugar cookie dough base, whole Oreos, and rich Duncan Hines brownie batter studded with Andes peppermint chips. The cookie layer softens into the fudgy brownie as they bake together, creating a complex texture with peppermint flavor throughout and optional garnish of crushed chips.

Instructions
- 1

- 6

Tips
Room temperature cookie dough spreads more easily than chilled dough.
When batter is poured, the center will remain slightly gooey; this is intentional and will set as brownies cool.
Good to Know
Covered at room temperature for up to 3 days, or refrigerated for up to 5 days.
Assemble in foil-lined pan up to 8 hours ahead; refrigerate unbaked, then extend baking time by 5 minutes.
Cut into squares and serve at room temperature or slightly warm, optionally with vanilla ice cream.
Common Mistakes
Do not skip covering with foil for the first 30 minutes to prevent overbrowning the cookie layer and chips.
Do not remove from pan immediately after baking; cool completely so structure sets and squares cut cleanly.
Do not fully bake until the center is completely firm; slight gooeyness is intentional and firms as it cools.
