These watermelon slice-shaped sugar cookies are a fun, easy, and colorful twist on classic sugar cookies, topped with smooth pink royal icing and a hint of citrus for brightness.
Chill dough for at least 1 hour to prevent spreading and maintain shape. Use room temperature eggs and butter for smooth texture. Adjust royal icing consistency with water carefully. Let royal icing dry fully before stacking or storing. For dairy-free, substitute butter with almond or coconut oil. For gluten-free, use a 1-to-1 gluten-free flour blend. Gel food coloring can be used instead of liquid.
