Why You’ll Love This Recipe
- Crowd-pleasing – makes a large pan so it’s great for parties.
- Easy – straightforward steps anyone can follow.
- Minimal ingredients – uses pantry-friendly items and just five main components.
Key Ingredients

Brownie mix – any favorite boxed mix or homemade brownie batter for the base.
Oreos – use regular or Mint Oreos for extra mint flavor; chop for layering and topping.
Mint ice cream – mint chocolate chip or mint cookie varieties work well; plain mint is optional.
Cool Whip – an easy whipped topping to mix with chopped Oreos.
Hot fudge – warmed and drizzled over the top for a rich finishing layer.
Substitutions and Variations
Swap the ice cream – any flavor can be used: Moose Tracks, Cookies & Cream, Birthday Cake, or Cherry Garcia are great choices. Add peppermint extract to vanilla for a quick minty option.
Different Oreos – match Oreos to the ice cream flavor; Mint Oreos enhance the mint profile.
Use an Oreo crust – replace the brownie base with an Oreo crust if you prefer a cookie foundation.
Make your own ganache – melt semi-sweet chocolate chips with a little heavy cream for a homemade chocolate layer instead of jarred hot fudge.
