Chocolate cookies rolled in sprinkles - basic cookie recipe for holidays (Christmas, New Year's Eve) or any special occasion (Birthdays, parties, anniversaries)
In a medium bowl, combine together flour, cocoa powder, and salt and mix.
In a separate bowl, using electric mixer, beat softened butter and granulated sugar on high speed until light in color and fluffy. Add in egg and vanilla – continue beating for a couple more minutes. Turn off the electric mixer, add flour-cocoa-salt mixture and then continue beating on low speed until well-combined but without over mixing.
Roll dough into 1-inch balls. Roll these cookie balls generously in sprinkles. Immediately arrange on parchment-lined baking sheets, spacing 2 inches apart and freeze until firm, for about 30 minutes.
Bake in the preheated oven at 350 degrees Fahrenheit for 14 minutes. Do not over-bake. Remove from the oven, and transfer to wire rack to cool completely.
