Thin Mint Mississippi Mud Brownies

Thin Mint Mississippi Mud Brownies

Those stinking Girl Scouts. They get me every darn year with the lure of Thin Mints. Gosh dang I love those cookies. I’ve tried making my own, but I didn’t like them. I’ve tried waiting on the little one to come to my door but we had two years where we paid and never got our cookies and to be honest I’m not even sure if they’re allowed to go door to door anymore. Which I’m totally on board with. It’s too scary to send your little one around. Anyway, years ago I was throwing my guts up from this pregnancy and my sweet friend from Brin and Bell wrote a guest post for me about devilishly delicious mint cookies and they got me thinking, why not create a Thin Mint Mississippi Mud Brownies recipe to get that flavor in my belly without having to wait on those girls to line up outside of Walmart.

I can just taste those frozen cookies! Do you freeze yours too? It’s pretty much the best way to enjoy a thin mint cookie.

So here’s the plan, since thin mint is my favorite girl scout cookie (sorry to Cade who loves the Samoas just as much) I’m having Amber from Dessert Now, Dinner Later work on a huge 100 recipe roundup of the best of the best thin mint recipes. Sounds fun right?! I can’t wait to get to it! Stay tuned!

When I was little the Girl Scouts would come around to our door and oh my goodness, joy filled the entire house when they finally arrived to deliver our cookies. It was like this crazy balance between wanting to eat the cookies before they were gone and you didn’t get your fill and trying to hang onto them and savor every single cookie. That’s a pretty hard thing to do with Girl Scout cookies. And seriously, who made those dang things up?! I never, ever care about packaged cookies but there is just nothing in the world that compares to those green boxes!

These brownies though, they are pretty fantastic and totally have that delicious thin mint awesomeness. Gooey, chocolatey brownie, andes mints, fluffy marshmallow and a perfectly rich chocolate frosting. Yeah, I’m pretty sold on these babies. Oh, and I do a little something special to make these brownies even more delicious and to taste a little more homemade, I sub butter for the oil. Melted butter that is. Try it, they are even more chocolatey and delicious.

Can Brownies Be Frozen?

Brownies can be frozen for up to 3 months.

Wrap them tightly in plastic wrap or foil, or place them in a heavy duty freezer bag and freeze.

Can You Use Salted Butter Instead of Unsalted?

If you’re baking a recipe that calls for unsalted butter (or doesn’t specify a butter) and you only have salted on hand, you can eliminate the added salt and still have a fabulous treat on your hands!

  • This sounds incredible! Just wondering…should I be concerned about those two rogue bullets beneath the two tablespoons butter listed for the frosting? Want to be sure there aren’t two critical ingredients that went AWOL, before I try this.
    Thanks!
