My homemade thin mints have a crunchy mint cookie coated in smooth chocolate. This easy recipe tastes just like the real thing and is as easy as slicing and baking, scouts honor!

If you’re like me, a sleeve of Thin Mints disappears in hours not days! My homemade version is perfect for when you've run out of Girl Scout cookies or are craving them off season. Stash some in the freezer, and cookie season will last all year long! Try my Tagalong copycat recipe too.


Why This Recipe Works: A Sprinkle of Food Science


  1. Add Cornstarch: Cornstarch doesn't form gluten like flour and also absorbs excess liquid for a crispy crunchy cookie.
  2. Leave Out the Eggs: This also leads to a drier, crispy cookie. They won't be cakey like my Texas Sheet cake cookies.
  3. Tempered Chocolate: This make the chocolate super shiny and gives it a nice snap when you bite into it. We make this process simple with the microwave.


Ingredient Notes and Shopping Tips
ingredients including flour, cornstarch, cocoa powder, sugar, butter, milk, vanilla, peppermint extract, and a baking chocolate bar.
  • Flour: Measure this by spooning flour into your measuring up. Avoid dipping your cup into the flour or you'll get too much which won't mix in smoothly.
  • Unsweetened cocoa powder: I used Dutch process cocoa because it gives them a dark color like the original and a rich chocolate flavor that won't outshine the mint.
  • Butter: Make sure butter is softened. You should be able to leave in an indent with your finger when lightly pressing it. Avoid cold butter which will be hard to mix and melted butter which can cause the cookies to spread too much.
  • Milk: Use whole milk for the best results.
  • Peppermint Extract: Be careful with this, it is very potent. Don't be tempted to add more than called for.
  • Chocolate: Baking bars will melt smoother than chocolate chips which contain stabilizers that can interfere with melting.


Krystle's Tips: Steal My Culinary School Secrets


  1. Don't skip the chilling step: Frozen dough slices cleanly and helps the cookies keep their shape.
  2. Slice evenly: ¼-inch inch will give you even cookies like the original and help them bake at the same rate.
  3. Watch your chocolate closely: Stir frequently and cook no more than 30 seconds at a time as it can scorch quickly.
  4. Don't skip grating the chocolate: This helps temper it which makes it super shiny never dull. It also raises its melting point so they don't melt in your hand when you're eating them. Bonus: It prevents fingerprints too!
