Pool Party Sugar Cookies: Party-Ready

Instructions:

1. Beat softened butter and granulated sugar on medium-high until light and fluffy (about 3 minutes).
2. Mix in the egg and vanilla extract until fully emulsified.
3. Whisk flour, baking powder, and salt in a separate bowl, then gradually add to the wet ingredients on low speed until a soft dough forms.
4. Wrap dough in plastic wrap and refrigerate for 1 hour to prevent spreading during baking.
5. Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
6. Roll chilled dough on a floured surface to 1/4 inch thickness and cut out rounds using a 2-inch cookie cutter.
7. Bake cookies 2 inches apart for 7-9 minutes until edges are just set but still pale.
8. Cool cookies completely on a wire rack.
9. Whisk powdered sugar, milk, corn syrup, and vanilla; stir in turquoise gel food coloring.
10. Spoon glaze into the center of each cookie and spread to the edges with a toothpick, leaving a small gap for the 'pool deck'.
11. Decorate with sanding sugar bubbles, gummy fish, and almond slivers as pool loungers.
