I know, I know. THREE Irish cream-related posts in a row? From someone who is a mere 1/8th Irish? It’s total overkill. I get it.
(In case you missed it: Homemade Irish Cream and Irish Cream Bundt Cake.)
But you have to strike while the iron is hot, right?
In this case, the iron is the rest of the batch of homemade Irish cream waiting in my refrigerator.
And I guess the fire heating the iron is the upcoming weekend cabin trip my husband is taking with the male half of our college friend group.
The obvious solution: mint Irish cream brownies.
Because when you’re spending the weekend with a bunch of guys in a log cabin existing on beer, scotch, and Doritos, what you really need are boozy brownies. Obviously.
Wilderness Survival 101, people. Essential.
Even better: these brownies are easy to double. As written, they make a 9×9 (or 8×8)-inch pan of brownies. Double everything and bake in a 9×13-inch pan.
Because when a group of guys is spending the weekend in the woods, you always double the batch of boozy brownies.
That’s Wilderness Survival 102.
Easy Mix By Hand Brownies
These mint Irish cream brownies start with a thick and fudgy brownie layer, whisked by hand in one bowl. So easy.
Top them with a minty, Irish creamy buttercream frosting — tinted with a little green food coloring. (Because mint should always be green – I’m looking at you with a side eye, white mint chocolate chip ice cream.)
Then cover the whole thing with a layer of melted chocolate (with a little more Irish cream, of course!).
And yes, these brownies are green and contain Irish cream and are perfectly festive for St. Patrick’s Day. But they’re also delicious year-round because chocolate and mint go with all seasons.
Boozy Brownies… Or Not
Not into Bailey’s Irish cream? Leave it out — just sub in heavy cream instead. These are delicious as plain mint chocolate brownies.
Family and work-friendly — and totally appropriate any time of year.
Not into mint in your brownies and want the flavor of your Irish cream to really shine through? Skip the mint extract and use a splash of vanilla extract instead.
Like your frosting EXTRA minty? Double the mint extract. Want a really super duper thick layer of chocolate on top? Double it.
These brownies were made to be adapted to your personal tastes.
Double for a 9×13 Inch Pan
As written, these make perfect 9×9-inch brownies or slightly thicker 8×8-inch brownies.
But if you need more boozy brownies (and hi, who doesn’t need more boozy brownies?), double the recipe and bake in a 9×13-inch pan.
The ingredient ratio for brownies, frosting, and chocolate ganache is the same, just add a few extra minutes to the baking time for 9×13 or 8×8-inch pans.
Regardless of what size you use, I love using a springform pan to bake these brownies. It’s so easy to add the layer of buttercream frosting and spread on the chocolate ganache while it’s still in the pan. Then when you’re ready to serve, run a knife quickly along the outside and take the sides off.
You can, of course, use an aluminum foil overhang in a regular pan, but I find the springform pan is much easier than lifting out brownies when a layer of frosting and chocolate is involved.
Regardless of what sort of pan you use, if you want the fudgiest brownies, opt for a lighter-colored metal pan. Why does this matter? It’s time for my favorite subject… kitchen chemistry!
Kitchen Chemistry
For the fudgiest brownies, bake in a light-colored metal pan. Darker pans transfer more heat into the brownies and cook the edges more quickly than the center, which results in dry and cakey edges.
Recommended Tools for Mint Irish Cream Brownies
- Mixing Bowls: My favorite mixing bowls – both microwave and dishwasher safe.
- 9×9 Inch Springform Pan: A springform pan makes frosting and spreading the chocolate on these brownies so easy.
- 9×13 Inch Springform Pan: If you want to double the recipe, use a 9×13 inch springform pan.
- Green Food Coloring: The perfect mint green gel coloring to tint the buttercream.
Tips and Tricks for The Best Mint Irish Cream Brownies
- To keep brownies family-friendly, omit Irish cream and replace the same amount of heavy cream (in both the frosting and the ganache layers).
- Make sure the brownies are completely cool before spreading on the frosting. Warm brownies will melt the butter in the buttercream frosting.
- Refrigerate the frosted brownies to chill the butter before pouring the chocolate layer on top. (Same as above — the warm ganache will melt the butter if the buttercream frosting is not chilled.)
- The recipe can be doubled and baked in a 9×13-inch pan. Add an extra 5 minutes to the baking time.
- Brownies can be enjoyed at room temperature or refrigerated, but taste fudgier and have a better frosting texture when refrigerated.
- Made too many brownies? (Impossible!) Leftover brownies can be frozen for up to 3 months.

Mint Irish Cream Brownies
Rich, fudgy chocolate brownies with a layer of mint Irish cream frosting and a chocolate coating. Perfect for St. Patrick’s Day – or year round!
Ingredients
For the Brownies:
- 8 tablespoons (113 grams) unsalted butter
- 8 ounces (226 grams) semisweet chocolate, chopped
- 3 eggs, room temperature
- 1 cup (198 grams) granulated sugar
- 1/2 teaspoon salt
- 2 teaspoons vanilla extract
- 1/4 cup (21 grams) natural unsweetened cocoa powder
- 1 (120 grams) cup all-purpose flour
For the Mint Buttercream:
- 8 tablespoons (113 grams) unsalted butter, room temperature
- 3 cups (341 grams) confectioners’ sugar
- 1/3 cup homemade Irish cream (or Baileys, Ryan’s, etc.)
- 1 teaspoon mint extract
- green food coloring
FOR THE Chocolate Coating:
- 6 ounces (170 grams) semisweet chocolate, chopped (~1 cup chocolate chips)
- 6 tablespoons heavy cream
- 2 tablespoons homemade Irish cream
Instructions
- Prepare the pan. Preheat the oven to 350 °F. Line a 9-inch square baking dish with aluminum foil and extended the foil over the edge, or use a square springform pan (recommended). Spray with nonstick cooking spray.
- Make the brownies. Combine the butter and chocolate in a large microwave safe bowl. Microwave the butter and chocolate for 1 minute at 50% power and stir. Continue microwaving in 1 minute increments at 50% power until chocolate is fully melted and mixture is smooth.
- Whisk in the eggs, one at a time, followed by the sugar, vanilla extract, and salt. Stir in the cocoa powder and flour with a wooden spoon. The resulting brownie batter will be quite thick; it will take some effort to stir in all the flour.
- Bake the brownies. Scrape the batter into the prepared pan, smoothing with a spatula into an even layer. Bake for 28 – 30 minutes, or until a toothpick inserted into the center comes out with a moist crumb. Transfer the pan to a wire rack to cool completely.
- Make the frosting. To make the frosting, beat the butter with a mixer until smooth and creamy, 2 to 3 minutes. Add in the confectioners’ sugar and Irish cream, beating for an additional minute or two, until fully incorporated. Add in the mint extract and the food coloring, one drop at a time and fully mixing before adding the next drop. Once the desired color has been achieved, turn the mixer up to high speed and beat for one minute. Frost the brownies with a spatula and transfer to the refrigerator. Allow the frosting to set in the refrigerator for one hour before covering with chocolate.
- Make the ganache. To make the chocolate layer, combine the heavy cream and chocolate chips in a microwave safe bowl. Microwave for 1 minute at 50% power, stirring well. Repeat until chocolate is melted and smooth. Whisk in the Irish cream, stirring well to combine. Pour over the refrigerated brownies, using a knife or offset spatula to gently spread into the corners. Return the brownies to the refrigerator for an hour, until chocolate is set, before cutting.
Notes
- To keep brownies family friendly, omit Irish cream and replace the same amount of heavy cream.
- Recipe can be doubled and baked in a 9×13-inch pan. Add an extra 5 minutes to the baking time.
- Brownies can be enjoyed at room temperature or refrigerated, but taste fudgier and have a better frosting texture when refrigerated.
Brownies should be stored in an airtight container at room temperature or in the refrigerator for up to a week. Brownie can also be frozen for up to 3 months. Thaw at room temperature or in the refrigerator before enjoying.

These brownies look amazing! The mint filling is calling my name.
Oh so cool…love the green color.. Brownies are my weakness and you added my favorite Irish cream and made it even better. Yum… absolute heaven.
1/8 Irish is enough reason for me! Love the brownies! My kids are going to go crazy over them!
Yummm. These brownies sound amazing and perfect for St. Patrick’s Day or for a bunch of guys hanging out in the woods. I’m sure they probably really appreciated these 🙂
OH that buttercream frosting! Be still my heart! These must be AMAZING and perfect for St. Patrick’s Day!
Oh, wow! Those brownies look so rich and dense that when I first saw them I thought I was looking at fudge. I would certainly love to be indulging in one or two of them. I’m pinning to make them for my grandsons. Thank you for sharing.
Love the contrast between the two different activities ?! These look amazing and I agree with you-these are year round treats because nothing goes together better than mint and chocolate. Lol, good call doubling the batch too-but I might just call it basic survival because they’re so good.
My kids would go bonkers over these. I bet you could add some matcha to the frosting to give it a natural green color. Yummy brownies!!
Mint and chocolate go together like peas and carrots… these look like a delish treat for Paddy’s Day!
Those are some decadent Brownie!..love those layers and I am sure kids will love it..
These are St. Patrick’s Day perfect. Love the colour. That classic flavour combination can be enjoyed year round. These look so addictive.
You had me at mint. Mint is a flavour that is welcomed into our home at all times. I kid you not. But, here’s a little tidbit for you – I don’t like fresh mint. Isn’t that weird? These brownies would sure hit the spot right now. I’m pinning for later. 🙂
I love mint this minty irish cream brownies calling my name. These are dense and rich chocolate treat. I can have few.
These sound like the best ever! Love mint and chocolate. Perfect for St. Patty’s day next week!
Your making my 75% Irish heart over here very happy. The last 3 out of 4 posts on my blog all contained an Irish liquer too. What the hell? Tis the season, right? These brownies look down right AMAZING! I want to lick the mint buttercream right from the screen. Now I’ve gone too far….but these brownies. To die for!
I’m loving all your Irish inspired recipes as I’m a big fan of those flavors…especially in desserts. These brownies look amazing and I could almost eat 2-3 of them. Bookmarking them to try later.
I’m weak when it comes to chocolate brownies. Can say NO to chocolate. Guilty as charged! 😉 That Irish cream frosting sounds AND looks really amazing. I could eat a whole pan of minty brownie deliciousness.
I can’t stop thinking of sweets lately, which is not good, l should really focus on losing that baby weight. Oh well, l guess that can wait! Who can possibly resist these amazing brownies? Mint happens to be one of my favourite flavour, love it! Could have some of these now!
I am really looking forward to these! I loved Andes mints as a kid and these remind me of them but these are so much better! Nothing makes a great weekend like boozy brownies!!
