These funfetti sugar cookies feature a tender, buttery base with colorful sprinkles and a smooth royal icing that dries to a delicate shell, perfect for patriotic celebrations and quick holiday baking.
Use room temperature butter for best creaming results. Do not overmix dough to avoid tough cookies. Chill dough to prevent spreading. Test bake a single cookie to check oven behavior. Adjust royal icing consistency by adding powdered sugar or lemon juice/water as needed. Cover royal icing when not in use to prevent drying. Let cookies cool completely before icing to avoid melting. For gluten-free, use a 1:1 gluten-free flour blend and chill dough extra. For dairy-free, substitute vegan butter and egg replacer. Meringue powder is a safer alternative to raw egg whites in icing.
