Thin Mint Cookies

Back in the day when I was a Girl Scout (Troop 348! Holla! Or was it 346?), we were expected to go from door-to-door peddling our thin mints and Samoas.  I would don my green skirt, green and white striped shirt and green sash with all of my badges and head to my mom’s office after school, where I would politely knock on people’s office doors and recite my speech about supporting our troop through the purchase of what amounted to a box full of sugar.  I would make chitchat while people filled in the sheet with their order and address and thank them with a toothless smile (I was 8 years old) as they dug in their wallets or pulled out their checkbooks (no CODs for this Scout!).  I would then hand deliver their cookies when they arrived.

I loved being a Girl Scout, because I’m an only child and spending an afternoon with a bunch of other girls making crafts and eating snack and learning all manner of useful things like how to start a fire with two sticks and every single verse to every song that was sure to annoy my family (remember this one The Other Day I Saw a Bear… a great big bear… oh way out there…?) was nothing short of magical for me.  I also loved that we had books on how to be a model scout and how to earn badges (be nice to the elderly! do all of your homework! learn to churn butter!) and had to wear a uniform.  That part has less to do with the only child thing and more to do with my need for order and to follow instructions.  I actually liked doing my Girl Scout homework (bet you didn’t know there was homework!)…

At any rate. Times have changed, kids.  Now, I get emails from parents asking me to purchase their daughter’s cookies or facebook updates asking for orders and even worse, it appears I can now buy my cookies online.  I realize that there are all kinds of creepy characters in the world nowadays, so going door-to-door isn’t the safest option, but I think part of the idea behind selling cookies–besides funding our weekend at Girl Scout camp–was to teach us to be independent and confident and, at the very least, how to convince people to buy stuff they didn’t actually need (a useful skill, I think).  I’m not quite sure what the lesson is when the parents are doing all the selling, money collecting and delivery.  Actually I do know, but I’d rather not think about it.

/End rant/

Where was I? Cookies! That’s how all of this started!! So Thin Mints were my–and just about everyone else’s–faves. Anything that combines mint and chocolate is going to make my top 10 list, but I also loved that there was a little bit of saltiness to the cookie, which made it different from other chocolate/mint combos.  I am under no illusion that anyone can replicate the Girl Scout Thin Mint, but someone put out a box of them at work the other day and I had this thought that until some Scout comes and asks me to purchase cookies in person, I am totally boycotting the cookie sale season and will make my own until these girls start knocking at my office door or at least write the parent sent emails themselves.  And yes, I do realize that I am depriving young girls of much needed cookie income, as well as the fact that I have also deprived myself of some happiness in a green box.  But revolutions are all about sacrifice.

I actually found a good recipe that satisfies the mint/chocolate/salt craving and is as close to a thin mint as I’m likely to get without breaking into the vault where the official recipe is likely hidden.  But, really, who am I kidding?  They are truly no substitute for the real thing.  And even though they are easy to make, they are not nearly as easy as opening a box and sitting down with a glass of milk and a good book (although I always found the wait time between cookie purchase and delivery way too long, so these will do during that lag time).  So, go buy your Thin Mints and support your local troop and send a bunch of girls off to camp for adventures and good times and memories that will last them well into their 30s.  Just maybe sneak in a little etiquette/life lesson about the merit of doing things on your own with your payment, ok?  I’m sure some girl could earn an extra badge for that…

Thin Mint Cookies via

For the cookie

  • 1 cup (4.5 ounces) all-purpose flour
  • 1/2 cup (2.25 ounces) unsweetened cocoa powder
  • 1/4 teaspoon salt
  • 1/2 cup butter, softened
  • 1 cup white sugar
  • 1 egg
  • 1/2 teaspoon mint extract

For the chocolate coating

  • 1 bag semi-sweet chocolate chips
  • 1 tablespoon vegetable shortening
  • 1 teaspoon mint extract (or more to taste)

In a large bowl, beat 1/2 cup butter or margarine until creamy (I used my KitchenAid on 4). Add the sugar, and beat until mixed well. Beat in egg and mint extract. Sift flour, cocoa, and salt together into a small bowl. Add flour mixture by halves into creamed mixture, beating well after each addition.

Divide dough in half. On lightly floured surface roll dough into two 1 1/2 inch diameter cylinders. Wrap each cylinder in waxed paper, and refrigerate 5 hours.

Preheat oven to 350 degrees F (175 degrees C). Thirty minutes prior to baking, place both cylinders in freezer. Remove one cylinder at a time, and slice 1/4 inch thick pieces with very sharp knife. Place on cookie sheets about 1 1/2 inches apart. Bake 8-10 minutes.

Melt 1/4 cup butter (or shortening) and the semisweet chocolate in a double boiler or in the microwave. Drizzle over warm cookies (I dipped my cookies completely). Place on wire racks, and let cool and harden. I recommend putting them in the freezer (as I would with the real deal).

    Hi Jen,

    I’m really sorry it didn’t work. Have you tried putting them in the refrigerator or freezer? Even without doing so, the chocolate will harden, but I do recommend chilling them a bit. You’ll be able to transport them when they harden (I put a bit of wax paper between layers). Please let me know if they turn out, and thanks for letting me know. I’ll retry the recipe.
