Lemme just get this out of the way right now. I'm not a huge mint fan. There are only a few things that I like the flavor of mint in. One is mint chocolate chip ice cream and the other is thin mint cookies. I always said they weren't my favorite Girl Scout cookies, but then I'd find myself eating one after the other until a whole sleeve was gone! If they were frozen, forget about it, haha! (if you've never tried them frozen, it's a game changer!).

I don't know what it is about these cookies, but they're so addictive for not just mint lovers, but all of us other people, too. Maybe it's the chocolate. Anything dipped in chocolate tastes better, right? Well, it doesn't really matter why they're addictive, just that they are. And now we can make them ourselves with barely any effort and if you close your eyes, you might just imagine you're eating the real thing! Actually, you don't even need to close your eyes. That's how much of a dead ringer they are!

Ingredients for thin mints

Kim's all purpose gluten free flour blend - a store bought blend may be substituted, but hasn't been tested.
Unsweetened cocoa powder
Kosher salt
Baking powder
Butter - you should be able to substitute with dairy-free butter if needed
Powdered sugar - powdered sugar versus granulated sugar incorporates better into this dough and makes it more of a crisp texture instead of chewy.
Egg white
Vanilla extract
Peppermint extract
Semi-sweet or dark chocolate - an alternative would be dipping or coating chocolate
Cocoa butter (affiliate link) - you can substitute this with canola oil, coconut oil, or any neutral flavored oil. See below for more details.

How to Make Thin Mints

Gluten Free Thin Mints FAQs

My Cookies Are Still Soft After Baking. Why?

Most likely you didn't roll the dough thin enough. Make sure you roll it to ⅛th of an inch thick or your cookies will take longer than 10 minutes to bake. If you'd prefer thicker cookies (although they're not called "thin" mints for nothing), just bake them a little bit longer.

How Can I Tell When the Cookies are Done Baking?

It's hard to tell when the cookies look exactly the same as when they went in the oven, but you can carefully touch your cookies with your finger to see if they're set. When they feel firm, they're done.

Do I Have to Use Cocoa Butter to Set the Chocolate?

No, you can either temper your chocolate or use melted coconut oil, canola, or vegetable oil instead of the cocoa butter.

What About Using Candy Wafers Instead of Real Chocolate?

Candy wafers are much easier to use than real chocolate, but they won't taste quite as good. They're a great option if you're a little hesitant to try working with real chocolate, however.

I guarantee that you will NOT be able to stop at just one of these Gluten Free Thin Mints.
