In our opinion, there is only one thing wrong with Girl Scout Thin Mint Cookies and that is that you can only buy them one time a year.   These Chocolate Mint Cookies are our attempt to recreate the yummy chocolate and mint flavor profile found in Thin Mints.  These sweet, chocolatey cookies are covered with our deliciously creamy Mint Buttercream Frosting and drizzled with dark chocolate. Yum, yum, yum! If you are a fan of Thin Mints or a bowl of Chocolate Mint Ice Cream we think you are going to love these cookies!

Frosting the Cookies

Step 5: Gather up your cookies and your The Best Mint Buttercream Frosting.
Step 6: Use a knife to frost the Chocolate Cookies with the frosting.
Step 7: Place 10-12 Ghirardelli Chocolate Melting Wafers in a plastic bag. Melt them in the microwave. Once melted, cut the tip off the bag and drizzle the chocolate over the Mint Frosting.  (Make sure you only cut the very very tip of the bag. You only want a small hole to give yourself more control over the drizzle.)
Step 8: Allow the chocolate drizzles to harden and the frosting to set up before serving.

Expert Tips and FAQ’s

Use Room Temperature Ingredients

Both the eggs and the butter should be at room temperature which will help your cookies turn out lighter and fluffier.  For the eggs, room temperature simply means not cold out of the refrigerator. If you forget to take the eggs out before you start making cookie dough you can put the eggs in a bowl of warm water for 5-10 minutes to warm them up.  The butter also needs to be softened to room temperature which means if you touch it you should leave an indentation on the stick of butter. Do not use butter that has been over-softened or melted.  If that happens you should use a different stick of butter or put it back into the refrigerator to let it set up.  We have a whole post about How to Soften Butter, click here if you need more information on how to do that.

Do you need to use a Mixer?

Yes. In our opinion, you need some kind of a mixer to make a good cookie dough. A stand mixer, while expensive, is a great investment if you believe you have a lot of homemade baked goods in your future. An electric hand-mixer also works well and you can probably find one for around $20. You can hand mix cookie dough in a pinch (which is how we did it growing up), but you will really have to use a lot of muscle to cream the butter and sugar, and eggs properly.

Cookie Dough Mixing Tips

Creaming the butter, sugar and then mixing the eggs in is the most important part of the cookie dough mixing process. Creaming is when you fully incorporate the butter and sugar together and add some much-needed air to the dough. We recommend creaming the butter and sugar for 2 minutes at medium-high speed and then mixing the butter/sugar/eggs for another 3 minutes at the same speed. Once you add the flour, you want to mix the dough as little as possible. Mix it too much and you will get tough cookies. Mix in the flour at low speed and continue mixing ONLY until the dry ingredients are incorporated into the dough. Make sure you scrape down the sides and the bottom to make sure all the flour has gotten mixed in.

Oven Tips

Everyone’s oven is different. We recommend starting with a test bake with a single cookie to help you hone in on the exact baking time for your oven. You should set your timer for 2 minutes less than whatever the recipe recommends. Once the timer goes off, open up the oven and see how your cookie is baking. Make corrections accordingly. Our oven has a hot spot in the back so we always rotate the cookie sheet halfway through the baking time to get a more even bake. Although this may seem like an unnecessary step, it is better to do this than burn a whole tray of cookies.

Storage/Freezing Tips

Cookies should always be stored in an airtight container.  They should be completely cooled before storing them. We usually add a layer of parchment paper between each row of cookies in our plastic container.  Cookies stored at room temperature should stay fresh for 3-4 days. You can also keep them in the refrigerator and that extends their freshness for up to a week. If you need them to last longer, you can freeze them for up to 3 months. You can pull them out of the freezer and leave them on the counter for 1 hour and they will be ready to eat.
