Thin Mint Brownies – Fudgy homemade brownies with thin mint cookies in each bite! Rich, chocolate-y and the perfect dessert.
If you know one thing about me, it is that brownies are pretty much my all time favorite dessert. I have had this Homemade Brownie recipe memorized since I was probably 7 years old. It was made so often when I was a kid, and is still my go-to.
And the only way to make brownies better is to mix in fun flavors! Today we are taking advantage of Girl Scout Cookie season and using Thin Mints.
This recipe is so easy you are going to want to buy a box or two extra of the Thin Mints, because you are going to be making these over and over.
What You’ll Need
- Butter
- Unsweetened Chocolate
- Sugar
- Eggs
- Flour
- Salt
- Baking Powder
- Thin Mints
Pretty standard brownie ingredients that most people have on hand already. You can definitely use a store bought mix and follow the instructions for the brownie part on the box. Or you can even make my Homemade Brownie Mix and have that in your pantry for when cravings strike!
How To Make Thin Mint Brownies
- Start by mixing together the melted butter with the chocolate until everything is nice and smooth.
- Beat in the eggs and sugar until they are fully incorporated.
- Stir in the flour, salt, and baking powder until everything is just combined.
- Next mix in your crushed Thin Mints.
- Bake for about 20-25 minutes until a tester comes out clean and they are done. Let them cool completely before serving.
Recipe Tips
- As with all brownies, it is best to slightly under bake them. They will continue to cook for a little while after you take them out of the oven and they are sitting in the super hot pan. So if you pull them out when they are already completely baked, they will be over done by the time you go to serve them.
- Don’t have Girl Scout Cookies. Keebler sells Grasshopper cookies in the regular grocery store that taste pretty much exactly the same. So you can make these cookies year round!
- You can use a brownie mix if you don’t want to make them from scratch. Just follow the instructions on the box and fold in the amount of cookies listed in the recipe before baking.
- Cover the brownies and store on the counter for 3-4 days.

Thin mints are such a weekness for me. I could eat a whole box in less than an hour! I love that you made them into brownies! I bet they were soooooo good!
Oh girl, this is dangerous territory for me, haha! I would eat the whole pan!
Your brownies look fudgy and delicious – something I would love to be sinking my teeth into! I love Megan’s blog – it is one of the first blogs I started reading back when I first started blogging myself. Her penguin appetizers are the cutest!
How fun! One of my favorite brownie variations is adding york peppermint patties, and I can only imagine that Thin Mints have a similarly wonderful effect. (Pssst… there are cookies called grasshoppers that are similar if you miss the Girl Scouts!)
These brownies make me all happy inside! 😀
I only wish I missed Girl Scout cookies season this year! Mine are just sitting on the shelf untouched. Perhaps I’ll have to give these a whirl and use up those thin mints.
These would do wonders for my current chocolate cravings!
Wow! This is totally my kind of brownie… my husband doesn’t like mint (I KNOW!!!), and if I made these, I would have to share this with my two-year old who doesn’t even like desserts (who are these people I live with!!!)… I am going to save this recipe for an occasion like a pot-luck! Thanks for sharing 🙂
Gah. What an incredible combination. I may not have any Girl Scout Cookies, but I’ll just head to the store and grab some Keebler Grasshopper cookies. They taste almost identical (and look almost identical too). These brownies are in my future.
if the thin mint weren’t delicious on their own you had to add them to a chocolaty-heavenly brownie. So hard to resist
