Beat butter and sugar with an electric mixer until light and fluffy
Add in egg and beat until blended
In a separate bowl, combine flour, cocoa, baking powder and baking soda
Beat in the flour mixture until blended and chill dough covered for at least 1 hour. Dough will be very thick!
Preheat oven to 350 F and line baking sheet with parchment paper
Roll dough into ping-pong sized balls using your hands, and lightly press them into a thick patty shape
Place about an inch apart on cookie sheet and bake for 12 minutes
Remove from oven and immediately press chocolate covered cherries into center, being careful to keep cookie shape intact
Allow to cool briefly, then transfer to a wire rack to cool
Once cookies are cooled completely melt white chocolate in a bowl and spoon into a Ziploc bag. Snip the end off a corner and drizzle onto cookies
Enjoy!
