These next-level mint brownies take a simple boxed mix and turn it into something truly show-stopping that'll crush any chocolate-mint craving you've got. When you bite into these, you'll get the perfect mix of fudgy brownie, crunchy Mint Oreos, and silky Andes mints – a combo that's always the first thing to vanish from my treat table.
I came up with these mint-chocolate layered treats for my boy's birthday when he asked for something chocolatey with mint flavor. They were such a massive hit that we now bring them to every family gathering and potluck as our signature dessert.
Ingredients
- Brownie mix with needed prep items: Forms the rich chocolate foundation for our minty layers
- Mint Oreos: Work double duty as the crispy base and pretty topping
- Andes mints: Create that smooth minty middle that makes these brownies instantly recognizable
- Butter for greasing: Makes sure your brownies come out of the pan without sticking or breaking
Step-by-Step Instructions
- Prepare the Pan:
- Thoroughly butter your 9 inch square baking dish, getting all the sides well. Put whole Mint Oreos flat across the bottom in one layer. Don't leave gaps between cookies. This cookie layer adds amazing crunch and flavor to your finished brownies. Take your time to fit them in nicely.
- Create the Brownie Layer:
- Follow the box directions to make your brownie batter until it's lump-free. Gently pour this over your cookie layer, making sure to cover every Oreo completely. The batter should go all the way to the edges and be even throughout the pan.
- Bake to Perfection:
- Stick the pan in your preheated oven and cook according to what the brownie box says, typically around 25 to 30 minutes. You'll know they're done when a toothpick comes out with just a few sticky crumbs on it. Don't leave them in too long or they'll get dry, so keep an eye on them near the end.
- Add the Mint Layer:
- As soon as they come out, put unwrapped Andes mints all over the hot brownies so they cover the whole top. Put the pan back in the warm oven for just 2 minutes to soften the mints without completely melting them. Take it out and use a knife to spread the soft mints into a smooth layer that covers everything.
- Finish with Oreo Topping:
- While the mint topping is still soft, scatter chopped Mint Oreos all over. Push them in just slightly so they stick but don't sink. Let everything cool on the counter for at least an hour until the mint layer hardens up.

Using store-bought stuff in this mix is my sneaky way to make killer desserts without spending forever in the kitchen. My little girl usually hates anything minty, but she always wants these brownies for birthdays and special days – that's how I know they're good enough for even the pickiest kids.
Slicing Secrets
To get those picture-perfect brownie squares, grab a sharp knife and wipe it off between cuts. For the cleanest look, stick the brownies in the fridge for half an hour before cutting – this firms up the mint so it won't smear. Weirdly enough, a plastic knife works amazingly well for these since the mint doesn't stick to it as much.

Storage Information
You can keep these mint treats fresh for about a week in a sealed container at room temp. If you want to save them longer, wrap each brownie in plastic and toss them in the freezer for up to three months. The fun part is that the mix of crunchy Oreo bottom and soft brownie middle actually gets better after a day as everything meshes together, making these great to bake ahead.
Customization Options
Though we call for Mint Oreos, normal Oreos work great if you want a milder mint taste. You can also swap in other Oreo flavors like peanut butter or birthday cake for a totally different twist. If you want to go all out, try adding a drizzle of melted chocolate over the top once they've cooled for extra richness and to make them look even fancier.
