“The mint and chocolate together in these were delicious!! So good.” -Jessica
What You’ll Need
Today’s recipe uses my favorite fudgy brownie as the base. It’s an easy, from scratch recipe that we use often and is loved by all! Scroll to recipe card below for full list.
- Unsweetened cocoa powder. The higher quality cocoa you use, the higher quality your brownies will taste. I get great results from Rodelle and Ghirardelli brands.
- Peppermint extract. Use pure peppermint extract (not imitation flavor) for best results. You’ll also need vanilla extract for the brownies!
- Gel food coloring. A few drops give the mint filling the traditional green color. You can leave this out if desired for a cream colored filling.
How to Make Mint Brownies
Brownie layer. Swap out the homemade brownies for a boxed brownie mix if desired.
Mint filling.
- Beat together all the ingredients until the filling is fluffy and smooth. When the brownies are fully cooled, spread filling on top.
- Chill the mint brownies in the refrigerator while you make the ganache.
Chocolate ganache. Pour the ganache over the mint layer of the brownies. You can use a spatula to make sure the tops of the brownies are fully covered.
Tips and Tricks
- Line your baking dish with parchment paper before adding the brownie batter. Easy removal and easy clean up!
- Do not let the cream simmer or boil when making the ganache. Boiling or scalding the cream will ruin the consistency.
- Be careful not to over stir the brownie batter. Use big strokes to mix in the dry ingredients just until you no longer see big lumps of flour. Over mixing will make your brownies tough.
- Swap out the chocolate ganache for a layer of chocolate buttercream instead!
- Love this dish? My no bake Grasshopper Pie is deliciously minty!

Rich and chocolatey with just the right amount of mint flavor, Chocolate Mint Brownies are perfection. Wow your friends and family with this beautifully indulgent dessert recipe!
Oh my gosh, I absolutely LOVE brownies and these look delicious! The mint looks a beautiful colour…I just want to bite your picture….lol. Of course it would be hard knowing whether to make these or the kitkat or double fudge that you also have featured….hm…maybe will have to make them all!
What a great use of the Duncan Hine’s frosting creation. I’m going to have to give those things a try. St. Patrick’s Day is all about something minty and chocolatey for me, and this fits the bill perfectly!
These brownies sound amazing Aimee! I love mint and that creamy smooth layer of chocolate on the top is making me really hungry! 🙂
I love any kind of brownies and these sound amazing! I have to get my hands on these Frosting Creations.
I always agree to a final layer of chocolate 🙂 These look prefect and I’m in love with the colors!
Thanks Sues! Can’t go wrong with extra chocolate!
I love that you used sweetened condensed milk for the minty ganache layer. I was just wondering the other day if ganache with sweetened condensed milk was a thing 🙂
LOL. I don’t know if it’s “correct” to call it ganache. But I couldn’t think of what else to describe the soft layer of mint 🙂
These look so sweet and fudgy and I love that minty layer-they’d be great for St. Patrick’s Day too!
Yay! I am so glad my brownies inspired you to bake these yummy looking brownies. Love the ganache mint topping with the chocolate glaze! I do have to say though, my fudge layer on mine was actually quite soft…something about being on the brownies didn’t let it set up quite as hard as normal…which was actually a really good thing 🙂 Now I think I need brownies…better make them today before my new diet starts on Saturday!!!
I can’t imagine a better feeling than my teeth sinking into this ganache (as my dentist probably shudders at the thought lol). Gorgeous brownies Aimee – keep ’em coming! Three months is FAR too long to wait for brownies like these 😀
Yep, that mint layer is extraordinary! Now I’ll be thinking about it! Thanks Aimee!
What a sweet St. Patty’s-Day treat! I’m totally with you on going for the soft mint layer. That’s my favorite part. OK, and the homemade brownie is pretty fab too. Good thing I don’t have to choose 🙂
Oh these look wonderful! They remind me or grasshopper fudge which is my absolute favorite!
I haven’t made grasshopper fudge in years! thanks for the reminder Audra!
Oh do these just look heavenly! I love mint brownies and these just are calling to me 🙂
Thanks Suzanne, I think you should answer the call 😉
These would be gone in a flash Aimee! Chocolate and mint – to die for!
Agreed!! Thanks Dorothy.
Chocolate and mint, two wonderful flavors. Cannot wait to try this recipe.
Mint is in the air! Love it! These brownies look so scrumptious and I love how they have thick layers, you can really get a taste and bite of each flavor!
Gorgeous mint + choco combo and such perfect layers! I just posted choc + mint yesterday and last year, I posted choc + mint brownies around this time, and they turned out to be one of my most popular recipes of the year!
Who can resist chocolate and mint??
I LOVE mint and chocolate together!! These look amazing!
