Seashell Sweets Sugar Cookies

Featured in: Sweet Seasonal Treats

Create charming seashell-shaped sugar cookies using a buttery dough blended with vanilla and baking powder for balanced texture. The dough is chilled before being rolled out and cut with a seashell cutter, then baked until just golden at the edges. A smooth royal icing colored in pastel pinks, lavenders, and turquoise decorates the cookies, enhanced by edible pearl sprinkles and shimmer dust to add a magical touch. This medium-difficulty dessert yields 24 cookies and suits vegetarian diets.

Chilling the dough aids in clean cutting and prevents spreading during baking. Using meringue powder ensures a firm icing ideal for detailed pastel decorations. For added flavor, almond extract can replace half the vanilla. Store these sweet treats in an airtight container to maintain freshness for up to a week.
