Set up a rolling station with the cookie dough, sprinkles, and a lined cookie sheet. For each cookies, scoop out about 1.5 tablesspoons of cookie dough and roll between your bowls to create a golf-ball-sized dough ball.
Lightly roll the dough ball in the sprinkles until fully coated. Place the dough ball on a lined cookie sheet. Repeat until there are about 12 cookies on the cookie sheet.
