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.

Yum! I have one box of Thin Mints in the freezer…hiding from everyone! They would be thrilled if I made them brownies instead anyway!
I haven’t had thin mints since moving to Australia in the last century. These look really good! I can’t wait to make these brownies!
Haha, I hate mint, but my wife would literally steal the pan out of your hands! I just bought my first ever box of girl scout cookies – for her! But I do admit that samoas are lovely. 😉
This is genius. What a great way to take one box of cookies and make it go so much farther. Well done!
Ohhhh how I love the thin mint girl guide cookies. This is a must try.
I like the combo of mint and chocolate. My kids and hubby LOVE it! We missed the girl scout cookies this season as well. It was the first year my daughter wasn’t in the girl scouts and noone came by! What’s up with that? I feel like we have been blacklisted since I pulled her out 😉 I haven’t even seen any booths set up. I’m going on a rant. Sorry. These brownies sound awesome! What a great SRC choice!
I could go for a couple of those brownies right now.
I have a Thin Mint weakness…these brownies look fantastic! I always try to miss Girl Scout cookies (as weird as it all sounds) but they are everywhere! Without even knowing Girl Scouts or having them knock at my door, I’ve bought way too many boxes outside of grocery stores lately 🙂
good choice – who needs penguins when you have chocolate and mint?? wait, i take that back. i love penguins. but to hug, not to eat.
happy src day!
Absolutely perfect! Much like fruits and veggies….Thin Mint cookies are in season right now!
