Girl Scout Cookie Season is upon us, and I for one could not be more excited. I may be jumping the gun here, but I really just couldn’t wait to share this recipe with you. As a child, I participated in Girl Scouts until I was “too cool” around 4th or 5th grade. That doesn’t mean I stopped buying the cookies though! It’s incredibly hard to resist those adorable little girls outside of the store asking “do you want to buy some cookies?” Umm YES PLEASE. Thin Mints are hands down my favorite, it just doesn’t get better than that. So when I overload my freezer with Thin Mints every year, I need an excuse to get rid of them. As such, the Thin Mint Brookie was born.

When I saw these Red Velvet Brookies from Ashton, I immediately started drooling. They were so beautiful! Having never made a brookie myself, I was quite intrigued. This recipe combines a fudgy brownie with a chocolate chip cookie loaded with mint chocolate chips and Thin Mint cookies. I found a bag of mint chocolate chip cookies at Walmart, and since mint chocolate is my favorite flavor combination, I picked up a few bags. If you can’t find them, just substitute regular chocolate chips. For added mint flavor in this recipe, substitute one of the two teaspoons of vanilla extract for mint extract.

For the chocolate chip cookie, I modified my favorite chocolate chip cookie recipe from Picky Palette. This is my go-to chocolate chip cookie recipe. Of coarse, you can make it easier on yourself by using some prepared refrigerated cookie dough from the store, but I love the softness of the cookie made from the dough I use.  This brookie is one of those “red light” desserts for me – meaning I had to get rid of them immediately after photographing in fear of eating the whole pan myself. Fact.

Thin Mint Brookies

Ingredients

  • 1 Sleeve Thin Mints
  • 1 Box brownie mix
  • 1 Large egg
  • 1/3 C Vegetable oil
  • 1/4 C Milk

For the cookie

  • 1/2 C (1 stick) Unsalted butter
  • 1/2 C Light brown sugar
  • 1/2 C Sugar
  • 1 Large egg
  • 2 tsp Pure vanilla extract
  • 1 3/4 C All-purpose flour
  • 1/2 tsp Salt
  • 1/2 tsp Baking soda
  • 2/3 C Mint chocolate chips

Instructions

  1. Preheat oven to 350° F.
  2. Empty one sleeve of thin mints into a Ziploc bag. Crush cookies into smaller pieces using a rolling pin or wooden spoon. Set aside.
  3. In a medium sized bowl, combine brownie mix, egg, vegetable oil and milk. Beat until thoroughly mixed.
  4. Line a 9×13” pan with parchment paper or a baking mat. Pour brownie mixture over the baking mat and spread evenly. Empty crushed cookies onto the top of the brownie mixture and spread evenly.

For the cookie

  1. Soften butter in the microwave 10-15 seconds. Combine butter with both light brown sugar and granulated sugar. Mix until smooth and mixture becomes fluffy.
  2. Add egg and vanilla extract and beat until egg is thoroughly incorporated.
  3. In a separate bowl, combine flour, salt and baking soda. Slowly add flour mixture to dough batter while mixing at a low speed. Once all the flour has been added, increase speed to medium until dough forms. Add mint chocolate chips last and fold into cookie dough.
  4. Take the cookie dough and drop chunks onto the top of the brownie mixture, gently pressing them down into brownie batter.
  5. Bake for 23-25 minutes at 350°F. Remove from oven and allow to cool before cutting. Since I used a baking mat, I was able to completely remove the sheet of brookies from the pan before cutting.

    These thin mint brookies are stunning. I’m not a talented baker, but I would love to give these a try!

  2. Jill Roberts

    I love this thin mint brookies recipe. I need to add a teaspoon of honey instead of 1/2 C sugar to recipe and it would be perfect! Thanks a lot for sharing, Julianne!

    These look so amazing. I saw them over at “time to sparkle link party” and I can’t wait to make them. Thin mints are so yummy and so dangerous to have around the house. Thanks for sharing!

    These look incredible Julianne! It’s one of those recipe that just stopped me in my tracks! I’m off to go hunt down some little girls so I can make these. That sounds weird. But no one has knocked on my door this year, I haven’t seen a single girl scout yet! Tragic!
