I adore sugar cookies. I love how they keep their shape and you can make anything you want out of them.
With mixer still on low, add in flour a cup at a time. Then add in cocoa powder and then sprinkle with pinch of salt. Mix until cocoa is incorporated, then turn off mixer.
Transfer dough to a piece a parchment paper. Place another piece of parchment paper on top and roll out dough to desired thickness. (Mine were about 1/2 inch thick)
Place dough (still sandwiched in parchment) in refrigerator for about an hour, or freezer for 15 minutes, until dough is firm.
When ready to bake, turn oven to 350. Remove dough and then remove one side of parchment. Using your chosen cookie cutter shape, cut out cookies and place on prepared cookie sheet.
Bake cookies for 8-11 minutes. Allow to cool to room temperature.
Cover cookies in white chocolate buttercream and enjoy!
