Copycat Thin Mint Cookies
Who on earth doesn’t like Girl Scout Cookies?! My favorites were always the caramel delights and thin mints. But if I’m being honest, I don’t think that there was ever a Girl Scout flavor I didn’t like. This recipe will let you enjoy thin mints year round 🙂

Copycat Thin Mints Key Ingredients
- Cocoa Powder – Using unsweetened cocoa powder will result in that deep, intense chocolate flavor in these cookies. Its natural bitterness helps balance the sweetness of other ingredients which gives us a perfectly well-rounded end result.
- Peppermint Extract – Peppermint gives off that cool and refreshing flavor that we all know and love in thin mints. The intensity of the peppermint flavor can be adjusted by using more or less extract, depending on personal preference but for the most accurate results to resemble classic Thin Mints.
- Egg White – Classic Thin Mints are crispy and delicious. The egg white not only helps bind our ingredients but adds stability to the overall texture of the cookie leaving us with a perfectly crisp, yet melt-in-your-mouth cookie.
- Semi-sweet Chocolate – For best results to resemble Thin Mints, use semi-sweet chocolate. If you prefer dark or milk chocolate, you can absolutely substitute for that.

Copycat Thin Mint Cookies Tips & Variations
Thin Mint Cookies aren’t soft and chewy, they’re more crispy. Although standard cookies might be done after 10 or so minutes or baking, be sure to bake these for at least 12 minutes. The recommended bake time is 15. To test the doneness, tap the top of the cookie. Your finger should barely leave an indent and the cookie should feel firm to the touch.
Leaving the cookies on the pan to cool also gives them that extra chance to crisp up just enough. Don’t worry about the overall texture of the cookie if they feel firmer than regular cookies – that’s how we want them!
Just like the classic Thin Mint Cookies, these taste INSANELY delicious after being placed in the freezer. That was always a must in my house growing up with Thin Mint Cookies. The cold cookie paired with the chilled temperature just…muah. Chef’s kiss!

I guess you add the dry mix after step 3? Haha! About to make this so I’ll make the assumption.
Thank you so much for this comment! I just updated the instructions. Yes the dry ingredients are added to the wet – after all the wet ingredients are combined. I’m sorry about that! I hope that you enjoy these! 🙂
I’m a vegan. Could I substitute the egg white with aquafaba (chickpea water) and yield the same results?
Hi there! I have not tried this and do not have much experience with vegan recipe testing so I can’t guarantee that the outcome will yield the same results. Please let me know how it goes if you give it a shot – I wish you luck! 🙂
