Our double frosted mint brownies have a thick layer of fudgy brownies, topped with a layer of mint buttercream, and fudgy chocolate frosting.
These brownies take me back to the famous BYU brownies college days! We've tried to recreate those nostalgic treats. Whether you are a BYU fan or not, you will love these mint brownies!
How to Make these Brownies
Brownies
Start with a double batch of our favorite fudge brownie recipe or your favorite brownie mix. We love Ghiradelli Triple Chocolate brownie mix. The brownies are chewy and fudge-like. For this recipe we used a 9x13-inch pan.
Make sure the brownies are totally cool before frosting or the buttercream will melt off.
Make the Mint Frosting
As long as you have a good brownie base, what makes these brownies special is our delicious mint buttercream frosting, covered by another layer of our chocolate fudge frosting.
The buttercream is fairly traditional, lightly tinted with mint color, and gently touched with mint flavor. It's important to remember the flavor and color should both be subtle.
We added the smallest touch of green paste color with a toothpick, then about double that small amount of blue paste color. Using liquid or gel color, we'd suggest a drop of green and two drops of blue. You can always adjust or add more color, but you can't remove it.
Mint flavoring is strong--we use a tiny bit of peppermint extract. Again, you can add more, but you can't take it back. We like about ¼ teaspoon. Mix it in and taste it to see what you think. Some people like a bit more mint, some like it just like this. Just remember, you don't want toothpaste frosted brownies!
Frosting the Brownies
Once cooled, loosen them from the pan, and turn them upside down on a platter or cutting board. Spread the mint buttercream over the brownie rectangle. Now you'll want to refrigerate the frosted brownies for at least an hour to really set the mint frosting.
Next comes our ultra delicious chocolate fudge frosting! Follow the recipe to create the frosting. While the chocolate frosting is still warm, spread frosting quickly over the already cold mint frosting covered brownies. Then chill again. It's easier to cut the brownies neatly while chilled.
We love the flavor combination of these tasty bars. Chocolate and mint are always a winner in our experience! To top it off, they're pretty too. Make the recipe for the holidays or save the recipe for St. Patrick's Day, or go ahead and make some any day. They're that good!

- ½ teaspoon vanilla
- ¼-1/2 teaspoon mint extract start with ¼ teaspoon, and add more if needed
- 4 cups sifted confectioners' sugar about 1 pound
- pinch of salt
- 2 Tablespoons milk more as needed

For Chocolate Fudge Frosting
- 6 ounces semi-sweet chocolate chips (about 1 cup)
- ½ cup cream can use half & half, cream, or milk
- ½ cup butter salted or unsalted
- 3 ½ cups powdered sugar
Instructions
Brownies
- Line 9x13-inch pan with parchment paper for easy removal from pan later. Make brownies in a 9x13-inch pan according to directions on mix or your recipe.
- Cool brownies completely before frosting.
Mint Buttercream Frosting (read all directions before proceeding)
- In medium mixing bowl, cream shortening and butter with electric mixer. Add vanilla and mint extracts.
- Gradually add sugar, one cup at a time, and salt, beating well on medium speed. Scrape sides and bottom of bowl often. When all sugar has been mixed in, icing will appear dry.
- Add milk and food coloring (see notes), and beat at medium speed until light and fluffy. Keep bowl covered with a damp cloth until ready to use. You'll be surprised how much color comes out of the smallest bit of food coloring.
- Spread mint buttercream over top of cooled brownies in an even layer. Place in refrigerator or freezer for one hour before adding layer of chocolate frosting.
Chocolate Fudge Frosting
- In a large, microwave-safe bowl, heat cream and butter in microwave until hot. Add chocolate chips to mixture and let sit for 1 minutes. Using your hand mixer on low, mix chocolate, chips and hot cream and butter until smooth and melted.
- Add powdered sugar with electric mixer. Beat until it holds its shape.
- Frost brownies with chocolate frosting when mint frosting covered brownies are COLD but chocolate frosting is still WARM. Chocolate frosting will set up like fudge when cooled.
- Chill brownies until chocolate frosting is set. It's easier to cut these brownies when they are chilled with a thin, sharp knife.
