These mint brownie cookies are just like a mint brownie in cookie form. They’re chewy and fudgy chocolate cookies, topped with a creamy mint frosting, and chocolate coating.
I love brownies. I love mint brownies. And I love these mint brownie cookies.
These mint brownie cookies are so easy to make, starting with a brownie mix for the cookie base. That keeps these cookies, fudgy in the middle, chewy on the outside, just like a piece of a brownie. Then topped with a smooth and creamy, green, mint buttercream frosting. And melted chocolate on top, that gets nice and hard, giving these cookies the perfect mint and chocolate flavor in every bite!
Ingredients Needed to make Mint Brownie Cookies:
- dry brownie mix – easy peasy, just a 18.25oz brownie mix from the store. A little bigger or smaller is okay, just adjust the flour added by 1 TBS either way
- eggs – to hold the brownie mix together and give the cookies a little lift
- flour
- vegetable oil
- vanilla extract
- butter – to hold the powdered sugar together in the frosting and give it a buttery flavor
- powdered sugar – to hold the frosting together and make it sweet
- half and half –
- peppermint extract – for the perfect mint frosting
- green food coloring
- salt – to balance out the sweetness
- chocolate chips – to melt and put on top of the frosting and cookies
How to make Mint Brownie Cookies?
Start by mixing together all your ingredients for your brownie cookies. You’ll need a box brownie mix, eggs, oil, flour, water, and vanilla extract. Stir it all together with a rubber spatula.
Scoop the cookie batter up by the Tablespoon (I recommend using a cookie scoop since the batter is sticky and not as thick as a normal cookie dough batter) and place them onto a cookie sheet lined with parchment paper. The cookie spreads a bit, so make sure to keep the cookies at least 2 inches apart.
Bake the cookies until the tops are crinkly, and no longer shiny. Remove the cookies from the oven, let them cool on the cookie sheet for about 5 to 10 minutes, then cool completely on a cooling rack.
Mix all the ingredients together for the frosting until it’s nice and fluffy and creamy. Spread the frosting evenly over the top of each cookie.
Melt the chocolate chips in a microwave safe bowl, then spoon it over the top of the frosting. Let the chocolate set, and then enjoy!
Tips for making the best Mint Brownie Cookies:
- These cookies bake fairly quickly and you want to make sure they’re not overbaked to keep those fudgy centers, so watch them closely the last couple of minutes. Bigger or smaller cookie dough sizes will affect the baking time.
- Don’t use Betty Crocker Brownie mix for these cookies. Normally I love that brownie mix, but it doesn’t contain baking soda like other brownie mixes, so these cookies will not rise with BC as they will with other brands.
How to store mint brownie cookies?
Mint brownie cookies can be stored in an airtight container in the fridge or at room temperature for up to 4 days.
These chocolate cookies have slightly crispy edges, soft, chewy, and fudge middles, paired perfectly with their mint frosting, and chocolate topping. They’re an easy to make cookie, that looks and tastes extra special. Perfect for making any day of the year.
