These Funfetti School Bus Cookies are a nostalgic, colorful treat featuring a tender sugar cookie base with rainbow sprinkles and a smooth vanilla royal icing perfect for school events and celebrations.
If dough is too sticky while rolling, chill for 10-15 minutes. Sift powdered sugar and flour to avoid lumps. Chill dough for at least 1 hour to prevent spreading. For royal icing, start with thicker consistency for outlines and thin slightly for flooding. Bake one sheet at a time and rotate halfway if oven has hotspots. Let icing dry completely before storing to avoid smudging.
