These Mint Oreo Ganache Brownies are rich, chocolatey, and full of cool mint flavor in every bite. You start with a simple boxed mix, add a layer of mint Oreo thins for crunch and flavor, then finish it all with a smooth dark chocolate ganache. This is the kind of treat that looks bakery-made but takes almost no time to pull together—perfect for parties, holidays, or just because.
Do I need to use Mint Oreo Thins or can I use regular Mint Oreos?
Mint Oreo Thins work best because they’re lighter and won’t sink as much into the batter, but regular Mint Oreos can be used if that’s what you have.
Can I use milk chocolate instead of dark for the ganache?
Yes! Milk chocolate will make the ganache sweeter and creamier—just be sure to use good quality chips.
Should the brownies cool completely before adding the ganache?
Yes, letting them cool ensures the ganache sets properly and doesn’t melt into the brownies.

Can I make Mint Oreo Ganache Brownies ahead of time?

How should I store the finished brownies?
Store them in an airtight container in the fridge for up to 4 days. Let them sit at room temp before serving for the best texture.
Can I freeze these brownies?
Yes, freeze them in a single layer until firm, then wrap and store for up to 2 months.
