Mint Brownies
Mint BrowniesI blame my mom for my Mint Brownies obsession; she would make them every year during the holidays, and they were everyone's favorite. Things got worse when I went to BYU and BYU Mint Brownies are everywhere! (Our recipe is better!). I love how Mint Brownies look impressive, with their pretty layers, but they’re surprisingly easy to make with basic ingredients. If you’re a fan of chocolate and mint together (hello, Thin Mints and Andes Mints!), these brownies are bound to become a new obsession.

How to make Mint Brownies:
Make Brownies: Mix sugar and oil in a mixing bowl. Add eggs one at a time, mixing well after each egg is added. Add vanilla. Add dry ingredients: cocoa powder, salt, flour, and stir until combined. Pour batter into a greased 9×13” baking pan and spread into an even layer. Bake at 350 degrees F for 30 minutes, or until a toothpick inserted in the center comes out clean. Cool completely before frosting.
Mint Frosting: Combine all frosting ingredients and beat until light and fluffy. Add more milk if you want it thinner. Spread the frosting evenly over the cooled brownies. Refrigerate while you make the chocolate frosting.
Chocolate Frosting: Combine butter and cocoa powder. Add powdered sugar, milk, and vanilla extract. Mix for several minutes until smooth and fluffy. Slice mint chocolate brownies into bars and enjoy!

If I could only eat one food for the rest of my life, it would be these mint brownies! I’M OBSSESED!!! I love how easy this recipe is to follow, and they taste amazing!
Hands down my favorite Mint Brownie Recipe!
I’ve made this recipe for years — except — I use 1-2 Tablespoons of Creme De Menthe Liqueur (Green) rather than Mint Extract which can be a little bit bitter. The Creme de Menthe adds a really nice flavor as well as the green color.
Hi Lauren,
I made these brownies for a wedding last night.
They are fabulous!
(Also had them for breakfast this morning). HaHa!
Love this post and I will be using it again.
For a wedding, I am trying to come up with a cute way to dress them up a bit…
maybe a tiny mint leaf a little piped rosette?
Hi Ciel, I’m so happy you liked them! A piped rosette would be really pretty for a wedding! You could also just do a bakery style design with a toothpick in the frosting before it cools. Sounds fun!
This recipe looked so good, I copied it down. I am due to make this this coming weekend. I thank you for the share.
I made these and was very happy with how they turned out. They were even delicious on the second day and didn’t get the crystallized sugar texture that brownies sometimes get. My new favorite brownie recipe!
Thanks Holly! I’m glad you liked them–I love that they keep well for few days!
We made these for New Year’s and they were spectacular. Then, my 9 year old was assigned a “how to” project and he wanted to remake these for that as well. We made batch #2 today to photograph the steps for his poster (and because he is very skinny from being sick -as he had no fat stores even before- and he can eat many of these. hopefully they will fatten him up a bit). We will have to make a third batch for him to hand them out to his classmates closer to the day. Of the presentation.Thank you for this recipe- it is already a favorite around here.
Thanks Kate that is so great to hear! Hope his class enjoys them 🙂
Funny thing… I was searching for a mint chocolate brownie recipe and this is the first one I have looked at! I did not know you had a blog!! Your mother has not told me!!
So I was looking at your picture and I thought you look familiar. and then I saw your name. Since I was talking to my son, Brent at the same time, I read your “about me” to him and it was cool to figure out that you are really YOU!!! So Cool!
I will be trying these brownies soon.
Hi Ciel, What an awesome coincidence–made my day! 🙂 Let me know how you like the brownies–I know you’re an amazing cook! 🙂
I miss Brent! My husband and I were just talking about him the other day wondering what he’s up to. We had a ton of fun together at BYU. Hope he’s doing well! Thanks for commenting 🙂
i love chocolate and mint. yum!
This is one of my husband’s favorite desserts, but I’ve never even attempted to make some. Thanks for the recipe
These look beautiful! I love mint brownies!
I love that everything about this recipe is homemade! And I love that the layer of frosting isn’t as thick as the brownie. That’s the perfect ratio to me 🙂
