These Double Mint Brownies taste like they came from a bakery! Fudgy chocolate brownies get all jazzed up with layers of Mint Oreos and Andes Mints to create a sweet, minty, chocolatey bite. Use a box of brownie mix and they’ll only take 10 minutes to toss together!
This easy Mint Brownie recipe reminds me of those classic after-dinner mints, but in rich, fudgy brownie form. We start with a layer of Mint Oreos baked into the brownies. Then while still warm, we melt a generous layer of Andes Mints over the top and sprinkle on even more Oreos. The end result is a decadent mint chocolate brownie that’s so good, you’ll never have leftovers!
“You can’t go wrong with these andes mint brownies, they are truly amazing and always the first to go. I use the Aldi brand of brownie mix and it works perfectly. I always sneaks a corner piece while they are still warm and before they’re fully set. I just can’t help myself, they are too good!” — Lyla, beginner cook who loves quick and easy recipes.
Ingredient Notes
Find the full printable recipe with specific measurements below.
- Brownie Mix: You will also need the ingredients (eggs, oil, etc) called for on the back of the box to make the brownie batter. I like to use Ghirardelli brownie mix, but use your favorite. If you want to go the extra mile, you can make homemade brownies instead!
- Mint Oreos: You will use one whole package of Oreos as we layer them in the brownies and chop more for the top.
- Andes Mints: Make sure you get enough! You’ll need about 56 mints total, which is 2 standard bags. You want to get a good thick layer of them melted on top to hold the chopped Oreos onto the brownies.

How to Make Mint Brownies
Visit the recipe card for the full directions.
Even if your pan is nonstick, grease it well. Or for even easier removal, line your 9-inch pan with parchment paper and leave an overhang. This makes lifting the brownies out simple.
Don’t over-bake the brownies. To keep them soft and fudgy, pull them out when the center is just set and a toothpick has a few moist crumbs. They’ll continue to cook slightly as they cool.
Have the Andes Mints unwrapped and ready to go. Spread mints on top of the brownies as soon as they come out of the oven. Let them sit for a couple of minutes before trying to spread them. The residual heat often softens them enough so you don’t have to put the brownies back into the oven.
Spread mints evenly. When spreading the melted Andes mints, use a butter knife, offset spatula, or the back of a spoon for an even layer. Once cooled and hardened, it’s what holds the chopped Oreos onto the brownies.
If looks matter to you, cool brownies completely before slicing. Give the brownies at least an hour for to set. This allows the mint layer time to firm up so you can get clean cuts.
Make Ahead and Storing
If making ahead for a party, you can prepare this mint brownie recipe the day before. In fact, they slice even cleaner the next day once fully set. Avoid refrigerating unless your kitchen runs very warm, as refrigeration can dry them out slightly.
Store leftover brownies in an airtight container at room temperature, they’ll stay fresh for about 4 to 5 days. Make sure they are fully cooled before storing to prevent condensation.
You can also freeze these mint chocolate brownies! I recommend individually wrapping each brownie tightly with plastic wrap or foil. Then transferring them to a zip-top freezer-safe bag, freezing them for up to 3 months. For best results, let brownies defrost at room temperature before enjoying!

Can you freeze these?
Yes! Double wrap them in plastic wrap and then put them in a freezer safe ziploc bag and you freeze them for up to 3 months! Thaw them at room temperature when you want to serve them again. 😉
Oh my! I made these for tomorrow, St. Pats Day. I doubled the ingredients, baked at 325° for 36min. in a 11×17 glass pan. I will be having 17 ppl for dinner. Update you on their reactions.
Hope everyone enjoyed them!
Everyone went NUTS over these for St. Pats Day, so I decided to make them for Xmas Eve fam party!
If someone is undecided about making these, DO IT! These are WONDERFUL 🥰
These brownies are amazing and worth every calorie!
But the nutritional information is very inaccurate…each brownie (1/12 of the recipe) can’t be less than 220 calories when the prepared box of brownie mix alone is over 250 each. Once you’ve added in the Oreos (70 calories each with approximately 30 cookies per package) and the Andes mints (25 calories each times 56), you’re over 500 calories per brownie. It’s not just the calories – 1 gram of sugar and 8 grams of fat for a brownie?
These are still very much worth making and enjoying though! It’s just good for readers to know what they’re actually consuming if these numbers matter to them.
I had to laugh at step number 5, where it says “Slice and serve or store in an airtight container for up to a week”. Who will leave those brownies UNEATEN for a week! LOL
It’s a good recipe! I assumed that you bake the brownies at 350 degrees Fahrenheit. (same temperature on the brownie mix box)
Hi Im in Australia and can’t get Andes mints but do you think after dinner mints would work? Not sure if they are they are the same thin but they are a thin rectangle with a thin mint cream in the centre coated in thin dark chocolate.
I’m from Australia too Tania & i would smash up peppermint crisp bars in place of Andes MintsGood luck
Hi Tania! I haven’t had after dinner mints, but I searched them and they look similar enough! Yes, I think they would work!
I used a 9 x 13 pan to stetch the recipe for a family birthday party. It fed the whole crowd well.
It was a hit. My new favorite dessert. Can’t wait to make again.
This recipe is a keeper! Very rich, minty, and addictive. Love it!!
Thanks so much Jessica for taking the time to look into it for me! I’m definitely going to try it now.
Made these for my church potluck. They were a huge hit. They are amazing.
Had to google Andes Mints, must be a regional thing, but they look similar to After Eights. I suppose any mint/chocolate wafer will work. I think I will definitely make this for my oldest’s next birthday. She loves mint chocolate ice cream. She’ll love this!
This look super delicious. Lovely pictures by your side makes it something to give try on this weekend.
What a mixture of emotions come along with that age, right?! Hoping the first day is easy for all. These mint brownies sure do look delicious!
I use cheese dip to cope with moments like these. Mine are 2 & 3 and they will always be my babies. And I know my kids would love helping whip up some of these brownies!
These brownies are packed! I could easily eat half of the pan in one sitting!
These look amazing. My kids would love them!
Oh, my!! These look so decadent and delicious! I love the mint/choco combo! Such a pretty cake plate, too!
Ugh, I’m trying to lose my last 5 pounds but there is no way that’s going to happen after seeing these brownies! Maybe I’ll hit the gym twice to make up for it. Gotta have these!! Chocolate plus mint are my favorite!!
We love Mint Oreos! These really do look like the ULTIMATE mint brownies!
