Graduation Sugar Cookies: Party-Ready

Instructions:

1. Beat the softened butter and sugar together until the mixture is pale and fluffy (about 3 minutes).
2. Mix in the egg and vanilla extract until fully incorporated and smooth.
3. Slowly add the flour, baking powder, and salt, mixing on low until a soft dough forms and no white streaks remain.
4. Divide the dough into two discs, wrap tightly in plastic wrap, and refrigerate for at least 2 hours.
5. Preheat oven to 350°F (175°C). Roll the chilled dough between two sheets of parchment paper to a thickness of 1/4 inch (6mm).
6. Use graduation cookie cutters to press firmly into the dough and cut shapes.
7. Place cookies on a lined sheet and bake for 8-10 minutes until edges are barely golden.
8. Let cookies sit on the pan for 5 minutes before transferring to a wire rack to cool completely.
9. Combine powdered sugar, meringue powder, and water, beating on high for 5-7 minutes until stiff, glossy peaks form.
10. Split the icing into small bowls and stir in chosen gel food colors.
11. Using a piping bag, trace the edge of the cookie to create a dam.
12. Fill in the center of the outline with icing to flood the cookie.
