Step 1

Preheat thee oven to 350°F. Line 2 baking sheets with parchment paper.

Step 2

In the bowl of a stand mixer fitted with a paddle attachment, mix together the butter and sugar. Mix in eggs, and vanilla. Add cocoa powder and mix until smooth.

Step 3

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the flour mixture to the sugar mixture and mix just until combined. Refrigerate the dough for 15 to 20 minutes.

Step 4

Using a medium cookie scoop (or about 2 Tablespoons), scoop the dough onto the baking sheets. Roll the dough balls and then lightly press the tops of the dough ball flat with your palm.

Step 5

Bake 8 to 10 minutes, or until the edges are slightly crisp, yet soft in the middle. Place 1 mint on top of each cookie immediately after they come out of the oven and let sit a few minutes on the pan.

Step 6

Move the cookies to a cooling rack. Using a spoon or knife, spread the melted mint on top of the cookies.

Step 7

Sprinkle additional chopped mints on top, if desired. Add after the chocolate has set for 1-2 minutes, so they don't melt. Let cookies cool before storing.
