Girl Scout cookie season is here! I get so excited when I see the first signs of Girl Scout cookies and I even make a special trip to the supermarket in the hopes of finding one of their cookie stands stationed in front. The only problem is that once I buy my cookies for the year, I really don’t want to run into them again because I hate saying “No” when they ask me to buy some cookies.

Then I find myself going to the grocery store at really odd hours or waiting for a bunch of people to walk out at the same time so that I can avoid them.

It’s become a tradition for me to make something with the Thin Mints I get every year. This year, I decided to cover them in brownies, combining two delicious things in one. These are super easy to make and you can decorate them however you wish. I originally drizzled some chocolate on top but Mr. K told me that it just looked like snakes were crawling on them (Thanks for the honesty Mr. K…), so I went with some green sprinkles instead.

Thin mint cookies are covered in a layer of chewy brownie. If you love brownies and you love Thin Mints, you should definitely try these out!


  • 1 box of your favorite brownie mix and any ingredients required by the brownie mix; you can also make brownies from scratch
  • 1 box of Thin Mints


  • Preheat oven to 350°F. Thoroughly grease two muffin pans.
  • Mix brownie batter according to box instructions. Using a spoon, carefully dip a Thin Mint cookie into brownie batter until it is completely covered in brownie batter. Remove Thin Mint and gently place into a greased muffin tin. Repeat with remaining Thin Mints. If you have leftover brownie batter, you can make individual brownies in your muffin tins after you are done with the Thin Mint Brownies.
  • Bake 8-10 minutes until brownie batter is cooked. Let brownies cool and then remove from pan using, using a spatula to loosen the edges. If desired, decorate with sprinkles or frosting before serving.

  1. Chocolate and mint is one of my favourite flavour combinations ever.. so I can imagine I would LOVE these thin mints. They look so rich and delicious!

  2. What a great idea to combine brownies with a Thin Mint cookie inside!  I like the use of the green sprinkles; very cute and attractive! 

    Haha, the lengths you went to avoid the Girl Scouts. We just order ours from the neighbor girls across the street and try to avoid supermarkets.

  3. I’ve been on the hunt for Girl Scout cookies all week! I can’t find them anywhere – oh my gosh I’m totally that creepy girl searching for girl scout cookies/hoping some girls will come to my door and sell me some. And even more so now that I have seen these! Must. make!!

    • Ooh, one year I had the same situation! I couldn’t find them at the supermarkets, and I was trying everywhere to find them. One day I was driving to a meeting, and there was a Girl Scouts van in front of me. I was sooo tempted to just follow the van until it pulled over, but then I didn’t. haha!

  4. I made brownies last week but mine didn’t have Thin Mints in them! Awesome idea. I don’t have any thin mints left, but kind of curious if I could do it with Ritz + peppermint. Hmm! 

    • I used all mine up to make these. they were delicious, but now I want more Thin Mints. The ritz-chocolate-peppermint is a great copycat version!
