A unique way to use up all of your Girl Scout cookies, these easy Thin Mint Brownies use boxed brownie mix for an easy dessert to throw together in minutes.
Were you ever a Girl Scout? I was a Brownie drop out. I didn't particularly care for Girl Scouts. I'm not really sure why but it just never really clicked for me. I was also involved in approximately 3049 activities growing up, so on the long list of activities, selling cookies door to door and braiding friendship bracelets didn't rank up there in the top 5 (and I'm sure Girl Scouts looks much different today). Now I'm buying cookies from all of my friends' kids and damn! These cookies, especially Thin Mints, are so poppable. I'll be sitting on the couch watching TV and BAM! I've polished off the entire sleeve in 5 minutes flat.
When you're not popping entire sleeve sin one sitting, sometimes it's nice to do something different with the cookies though. Otherwise, these cookies sit in my pantry while I try to maximize extreme adult restraint on a nightly basis between the months of January through April. These Thin Mint Brownies are just the way to elevate your favorite boxed brownie mix with your favorite Girl Scout cookies.
How to Make Thin Mint Brownies
This isn't much of a recipe because you really only need a couple of things:
- Thin Mint cookies - You'll need just one sleeve of cookies, approximately 20ish total
- Your favorite brownie mix
- Whatever ingredients the brownie mix calls for. We use Ghirardelli double chocolate brownies we buy from Costco, so one package of brownie mix calls for vegetable oil, water, and an egg.
Once your brownie mix is combined, crunch your Thin Mint cookies into tiny pieces using either a food processor or the old fashioned way with a freezer bag and a rolling pin until the cookies are crumbs. Then combine the cookies with the brownie batter.
Bake at 325˚F for around 30 minutes or until the insides of the brownies come out clean when poked with a toothpick.
Brownies From Scratch
If you prefer to make your Thin Mint brownies from scratch, I strongly encourage you take a look at these seriously fudgy brownies and add in the crushed Thin Mints.
Other Recipes Using Thin Mint Cookies
It's no secret that I LOVE me some Thin Mints. These are some of my other favorites using my favorite Girl Scout cookies:
Let's draw out Girl Scout cookie season as long as possible!

- Preheat oven to 325˚F. Grease then line a 9" square cake pan with parchment paper. Set aside.
