Thin Mint Cookies

We all know thin mint cookies from the Girl Scouts. Who knew you could duplicate them in your own kitchen?

I found this recipe and thought I would give it a shot. Never thought a homemade version could be as good, if not better.

My sister claims these were better than the Girl Scouts version. I’ll take that as a win.

How to Make Homemade Thin Mint Cookies

Whisk together flour, cocoa powder, baking powder, and salt in a large bowl.

Beat the butter and sugar together with a mixer on medium-high speed until pale and fluffy.

Beat in egg and peppermint extract until combined.

Reduce speed to low and gradually add flour mixture; beat just until incorporated.

Divide dough in half and use damp hands to shape each portion into a 10-inch log.

Wrap in plastic and refrigerate until very firm, about 2 hours (rotate dough occasionally while chilling to prevent flat sides).

Bag of semisweet chocolate chips and peppermint extract.

Preheat the oven to 350°F and line two baking sheets with parchment paper.

Use a sharp knife to cut logs into slices (just shy of 1/4-inch thick), rotating rolls to keep them from flattening.

Bake for 9 minutes, until edges are set. (bake time may vary)

While cookies cool, place chopped semi-sweet chocolate in a double boiler, or in a heat-proof bowl over a saucepan of gently simmering water. Slowly melt the chocolate, stirring occasionally until glossy and smooth.

Stir in mint extract and reduce heat to low so that coating will retain its consistency.

Line two baking sheets with parchment paper.

Don’t judge these cookies by my not-so-perfect semi-round shapes. I’m terrible at this sort of thing.

Drop cookies into the melted chocolate mixture one at a time to fully coat.

Lift the coated cookies out of the chocolate with a fork, tapping the fork gently against the bowl to allow excess chocolate to drain off.

Place coated cookies on prepared baking sheets and freeze or refrigerate until the chocolate coating is set (about 15 to 20 minutes).

Tips

Always measure your flour properly. Aerate, spoon, and swoop level.
Use room temperature unsalted butter. Using salted butter varies in salt level so you’re never sure how salty the cookies will turn out.
Double check and be sure you are using peppermint extract not mint extract. Mint extract is a combination of spearmint and peppermint. The mint extract gives a sort of toothpaste flavor.
Be sure to chill the dough. Chilling the dough allows the butter to solidify and helps keep the cookies from spreading.
You can use semi-sweet chocolate chips instead of block chocolate.
You can add 1 teaspoon of coconut oil or vegetable oil to the chocolate to make it thinner and easier to dip.
Use a fork to lift the cookies out of the melted chocolate.
