Making

In a small bowl, stir together flour and cocoa. Set aside. 

In a large bowl, cream together butter, brown sugar, white sugar, salt, baking powder, baking soda, and vanilla, using an electric mixer on low to medium speed. 

Beat in egg, scraping down bowl, as needed. Stir in cocoa-flour mixture. 

Fold in all of the Reese’s Pieces, except for ½ cup. 

With a large cookie scoop (about 2 ½ tablespoons), drop approximately 16 scoops of dough on lightly greased baking sheet (or baking sheet lined with a silicone pad). 

Gently flatten the cookies with the bottom of a drinking glass, then decorate with reserved ½ cup of Reese’s Pieces. 

Bake at 350 degrees (F) for about 8 minutes. 

Cool in pan for about 10 minutes on a cooling rack, then loosen with a metal spatula. 

Serving

Let cool, as desired, then place on a nice plate for serving.
