Celebrate graduation with these soft, buttery sugar cookies shaped like caps and diplomas, decorated with smooth royal icing for a festive and personal touch.
Chill dough for at least 1 hour for clean shapes and less spreading. Use two consistencies of royal icing: thicker for outlines and thinner for flooding. Let each icing layer dry fully before adding the next to prevent bleeding. Add a drop of water if icing thickens while decorating. Use a fan on low to speed drying but avoid cracking. Dough can be made ahead and refrigerated or frozen. Freeze undecorated cookies flat with parchment between layers.
