Sandwich Star Sugar Cookies

In a large mixing bowl beat butter with an electric mixer on medium to high speed for 30 seconds. Add granulated sugar, baking powder, and salt. Beat until combined, scraping sides of bowl occasionally. Beat in egg, milk, and vanilla until combined. Beat in as much of the flour as you can with the mixer. Using a wooden spoon, stir in any remaining flour. Divide dough in half. Cover and chill about 2 hours or until dough is easy to handle.

Preheat oven to 375°F. On a lightly floured surface, roll one dough portion at a time to 1/8 to 1/4 inch thick. Using a 2-1/2- to 3-inch star-shape cookie cutter, cut out dough. Using a 1-1/2- to 2-inch star-shape cookie cutter, cut a star shape from the center of half of the cookies. Place cutouts 1 inch apart on an ungreased cookie sheet.

Bake for 7 to 10 minutes or until edges are very light brown. Transfer cookies to a wire rack; cool.

Outline and flood the cookies with cutouts with glaze-consistency white Royal Icing; sprinkle icing evenly with white nonpareils. Set cookies aside. Spread 1 teaspoon lemon curd on bottom of each cookie without a cutout. Top with a glazed cookie, bottom side down, to make a sandwich.
