Sugar cookie bars have quickly become my favorite shortcut in the kitchen. Instead of rolling dough, cutting shapes, and spending hours decorating individual cookies, I just press the dough into a pan and bake.
Over the years, I've made quite a few fun versions, like lemon cookie bars, unicorn bars, and s'mores cookie bars.
Right now, I can't get enough of these chocolate mint bars! They have a fluffy mint frosting on top of a soft, chewy cookie base. Instead of sprinkles, I added some chopped up Andes mint bars for a nice crunch and some extra flair with every bite.
Why You'll Love These Chocolate Mint Bars
- Made in one pan! The dough is baked and frosted in a 9x13 pan, so no more rolling pins or cookie cutters are needed.
- Awesome chocolate mint flavor. The dark chocolate sugar cookie, fluffy mint buttercream, and Andes mints have the best chocolate-to-mint ratio.
- Fun holiday dessert. These dessert bars are the perfect dessert for St. Patrick's Day and Christmas, but honestly, they are delicious all year round!
Ingredients Needed
Here are the simple ingredients you will need to make this chocolate mint bar recipe. Scroll down to the printable recipe card for the complete list of ingredients and instructions.
- Butter: I prefer to use unsalted butter and adjust the flavor by adding salt myself. Set it out ahead of time, so it's ready to cream with the sugar.
- Sugar: A mix of granulated and brown sugar adds sweetness and moisture. The molasses in the brown sugar keeps the base soft and chewy for days.
- Large Egg and Milk: Adds moisture and holds the ingredients together.
- Vanilla Extract and Salt: Adds flavor and balances out the sweetness.
- All Purpose Flour: For best results, fluff and spoon the flour into a measuring cup or weigh it on a kitchen scale for accuracy.
- Dark Cocoa Powder: Choose Dutch-processed cocoa powder, which has a smoother, less acidic flavor than regular cocoa and gives it a rich, dark color. Natural cocoa is fine, but add a pinch of baking soda to mellow the acidity.
- Baking Powder: Gives the dough a lift as it bakes.
- Toppings: Mint buttercream and Andes Mints
How To Make Chocolate Mint Cookie Bars
These mint chocolate cookie bars come together so quickly. The best part about this dessert is that you bake and frost it in one pan.
- Make the cookie dough. Use a stand mixer to beat the butter and sugar until smooth and creamy. Add the egg, vanilla, and milk, then mix again. Slowly mix the dry ingredients into the butter mixture.
- Bake and cool. Press the chocolate mixture into an even layer in a greased 9x13 pan, then place in a preheated oven. Once done, cool on a wire rack.
- Make mint frosting. Beat the butter, vanilla, mint extract, and salt until creamy. Slowly beat in the powdered sugar and heavy cream until light and fluffy. Tint with green food coloring to get the shade you like.
- Decorate. Spread the icing on the cooled chocolate layer. Add mint chocolate chips to the top, if desired.
Optional Toppings
You can easily adjust the toppings to decorate the treats for different occasions or holidays.
- Green sprinkles or glitter for St. Patrick's Day
- Chopped mint Oreo cookies
- Chocolate ganache topping
Storing and Freezing
On the Counter: Keep the frosted mint cookie bars in an airtight container at room temperature for 4-5 days.
In the Freezer: Wrap each bar in plastic wrap, then place them in a freezer-safe bag or container. Freeze for 1-2 months. Thaw overnight in the fridge, then unwrap and bring to room temperature before serving.
BruCrew Tips
- Line the bottom of your pan with foil or parchment paper to make it easy to remove the bars after baking.
- If you are using a hand mixer to make the dough, the ingredients will take longer to come together. Continue beating until it becomes soft and pliable.
- Do not overbake the bars to keep them soft and chewy.
- Let the bars cool completely before frosting and cutting. Even the slightest bit of heat will cause the frosting to melt into the bars.
- For the cleanest cuts, run a sharp knife under hot water, then dry it off before slicing. Wipe it clean between cuts, and reheat it under hot water every few slices.
- Mint can be a polarizing flavor. I enjoy it paired with vanilla to soften its intensity. Peppermint extract can be used if preferred.

Dorothy @ Crazy for Crust says

Jocelyn Brubaker says
Thank you so much for the pin love 🙂
Laura says
I want to make these in a jellyroll pan. Do you think I need to double recipe??
Jocelyn says
What size pan are you thinking about using? A 15x10 or 12x17? Since I used a 9x13 pan for these, you could just do a single batch for a 15x10, but bake it a minute or two less. If you are using the bigger pan, you may need to do an extra half of a batch. A double batch may be too much, but you could always try it and adjust the baking time a minute or two longer since it will be thicker. Definitely keep me posted on how they turn out in the jelly roll pan.
Gayle @ Pumpkin 'N Spice says

Beth says
I LOVE making sugar cookies (said no food blogger ever!!). They are super cute, but very time consuming, I adore this easier version!
Jocelyn Brubaker says
Hahaha! I hear ya! Let's just stick to the easier version!!!
Laura @ Raise Your Garden says
Chocolate & mint is the ultimate temptation for me, my ultimate weakness. But even after a big dinner, I still want to indulge in fudgy bars like these. No cookie cutter even better. And the dollar section at Target, I must spend a mortgage payment amount there every week! But it's fun =)
Jocelyn Brubaker says
Any sugar dessert is my down fall...but yes, these were even harder to resist! And Target knows just how to get all my money every week...it is too fun though!!!
Mir says
Why mess with cookie cutters? I mean, I get it, it's cute, but all that work! And these are just as gorgeous (if not more so) and so delicious! I'm loving the frosting!
Jocelyn Brubaker says
They are cute...but so much work. I am totally all over cookie bars right now. And the frosting was seriously the best part 🙂
Averie @ Averie Cooks says
They look so dense, fudgy, and just perfect! Wanna take a big bite out of one 🙂 Pinned!
Jocelyn Brubaker says
Believe me I took way to many bites for those very reasons. Thanks for pinning girl!!!!
