DIRECTIONS:
Step 1
Preheat the oven to 325F and line a large baking sheet with parchment or a silicone mat.
Step 2
In a medium bowl, whisk together the almond flour, cocoa powder, baking powder, and salt.
Step 3
In a large bowl, beat the butter with the sweetener until well combined, then beat in the egg, vanilla, and peppermint extract. Add the almond flour mixture and beat until the dough comes together.
Step 4
Roll the dough into 1 inch balls and place 2 inches apart on the prepared baking sheet. Press each ball down to about ½ inch thick, then create an indentation by pressing your thumb into the center of each cookie.
Step 5
Bake about 15 minutes, until puffed slightly and the edges are just firm to the touch. Remove from the oven and if needed, re-form the indentation by gently pressing in with the back of a wooden spoon. Let cool completely on the pan.
Step 6
In a small saucepan over low heat, melt the chocolate and butter together until smooth. Stir in the peppermint extract.
Step 7
Use a small spoon to add about ½ teaspoon of the chocolate mixture to the center of each well. Sprinkle with sugar-free sprinkles, if desired, and let set until firm, about 1 hour.
