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.

Yummy I haven’t had any good brownies lately 🙁 Yours look amazing! Thanks for sharing!
You’re so lucky that your school lets you send homemade treats! We can’t do that :-/ These look fabulous!
We can’t send in homemade treats for the kids, but the teachers will gladly accept it. I learned the hard lesson after I made a Christmas snack mix for the kids – got sent back to me 🙁
I really like mint and chocolate… it’s so refreshing and tastes great after a meal. This would be the perfect little dessert. 🙂
Oh this sounds really really good Erin..even though I am not huge fan of mint I could go for this right this moment!:))
I love the addition of Thin Mints. I made some cheesecake thin mint brownies last weekend, they were a hit!
I haven’t met very many brownies I didn’t like but I can tell I’d love these! How can I not with the addition of thin mints?! 🙂
Great recipe!! I have a box of thin mints that I don’t want to eat, but crushing them into a brownie is a great idea!! This recipe is very simuliar to my brownie recipe, but your uses less butter! I love that!
I love thin mints and I love brownies and I’m head over heels for this combination Erin!
Two of my fave things…brownies and girl scout thin mints! Sounds minty delicious!
I haven’t had one of these brownies in a long time. I use to be a leader and always had GS cookies around this time of year, so we mixed up more than our fair share of these brownies. Great pick! 🙂
