Girl Scout cookie season is on the horizon, and it’s time for some easy, chocolatey Thin Mint Brownie Ice Cream Sandwiches!
Dish Count :: 2 Mixing Bowls, 1 Baking Sheet

My spidey senses are starting to tingle. About this time every year I get this feeling coming over me. Well two feelings. One, it’s time to start planning for my garden – my garden catalog just arrived and it’s time to pick out the planter friendly herbs and veggies for the balcony. And two – Girl Scout Cookie Season is coming soon. The ice cream is already in my store… so I’m ahead of the game.
It is an impossible task to pick my favorite Girl Scout Cookie, and it’s always a toss up between Samoas and Thin Mints. I have a whole category of recipes dedicated to Girl Scout cookie recipes! But this time I wanted to create a recipe just for Thin Mints with these Thin Mint Brownie Ice Cream Sandwiches. The outside brownie sandwich is ultra chocolatey, and the inside chocolate Thin Mint ice cream is divine.

But now, apparently, they’re selling them online? You CAN buy them all year long? I don’t know about you, but I live for my once a year cookie treat, and don’t want to jump ahead. It spoils the sanctity, right? If cookies had sanctity in the first place… They’re cookies, I need to get over myself. But their GS cookies. A whole ‘nother thing.
What Ingredients are Needed for Thin Mint Brownie Ice Cream Sandwiches?
To make this simple, you can buy Girl Scout Thin Mint Ice Cream! Or if you can’t find that, use a Mint Chocolate Chip or Mint Cookies and Cream if your store carries that! Either way, it will be delicious!
- Butter, melted
- Sugar
- Eggs
- Salt
- Flour
- Cocoa Powder
- Thin Mint Ice Cream – or Mint Cookies and Cream

How To Make Thin Mint Brownie Ice Cream Sandwiches
- Preheat oven to 350 degrees. Butter a 10×15 inch jelly roll pan with butter. Line with parchment paper. Do NOT use waxed paper in this application. Spray the parchment paper as well with non stick spray or use additional butter to grease the paper.
- In a large bowl whisk together melted ½ cup of melted butter and sugar. Whisk in eggs and salt. Whisk in flour and cocoa until just smooth. Spread into a thin layer all over to the edges of the pan.
- Bake for 10-12 minutes or until the brownies begin to pull away from the sides of the pan.
- Remove from oven and let cool in the pan for 5 minutes. Using the overhanging paper, gently remove the brownies from the pan and allow to cool completely on a wire rack.
- When completely cool, cut the brownies length-wise into two long pieces. Place one half of the brownie back into the pan and spread the softened ice cream and spread until smooth and even. Top with other half of the brownie.
- Cover tightly with plastic wrap and freeze for about two hours, until set. Cut into 6-8 sandwiches. Wrap each sandwich with parchment paper for storage and place in an air-tight container until devoured.

And this why I love you! I can’t wait to make these!! xoxo
I just happen to have some leftover thin mints from my popsicles. This dessert looks amazing.
Brownies are my fave, obviously, and these look awesome!!
My daughter sells these and our freezer has 4 boxes in their right now…ooo err!
I’ve been thinking a lot about my garden too, but I know I can’t do anything with it for at least another month. And thanks to the girl scouts showing up in front of the grocery store a last weekend I’m now thinking about buying cookies and making these ice cream sandwiches! Thin mints are the best!
Always love your girl scout cookie creations, so creative! And these are no exception. Thin Mints are my favorite and I want to eat all of these sandwiches!
I remember those samoa milkshakes! Yum. These look just as glorious. And surprisingly easy!
Oh my goodness. These look outstanding.
Total gorgeousness! I’ll take two – no, make that three! 🙂
I’m excited for girl scout cookies – I have to try to order some asap!
You always have the BEST Girl Scout Inspired recipes!
These ice cream sandwiches look amazing but you just blew my mind about those loofahs. I thought they were just the poofy shower ball thingy from Walmart that falls apart way too often.. ha! I had no idea the real thing was actually a plant.
A bath where I ALSO get to eat these ice cream sandwiches?? Where do I sign up?
These get me excited about girl scout cookie season! Looks yummy! I would have though loofah came from the ocean too. Weird!
These would be gone in a heartbeat around here!
