Dark Chocolate Thin Mint Cookies

Dark Chocolate Thin Mint Cookies

These rich, dark chocolate, thin mint cookies are not as heavy and filling as other holiday cookies. They serve as the perfect slice of holiday goodness for otherwise “average” December days. Each of which can, and should, be celebrated in their own little way.


For the cookies:

2 C. flour

½ C. cocoa powder

½ tsp. salt

Related Items

1 tsp. baking powder

1 C. butter

1 large egg

¾ C. sugar

1tsp. vanilla extract 

1 tsp. peppermint extract

For the coating:

2 x 4 oz. package baking chocolate (I use one 56% cacao and one sweet german’s 48% cacao)

1 tsp. vegetable oil

1tsp. peppermint extract

1 tsp. vanilla extract


  1. Preheat the oven to 375 degrees
  2. In a mixing bowl, combine flour, cocoa powder, salt and baking powder
  3. In a separate bowl, beat together butter and sugar until creamy. Add in egg, vanilla extract and peppermint extract until well combined
  4. Add the dry ingredients to the butter mixture, bits at a time until well combined. The dough should be thick
  5. Chill the dough until hard
  6. Roll dough out to ½ or ¼ inch sheets and cut into desired shape
  7. Bake in the oven for 8-10 minutes. *Don’t walk away from the kitchen during this step! The cookies may take less time depending on cookie thickness and oven temp. These cook very fast!
  8. Let cookies cool completely before coating

For the coating, melt baking chocolate, extracts and oil in a saucepan, over low heat, until well combined. Dip cooled cookies into chocolate mixture with a fork.
