Sweetheart Sugar Cookies Recipe | MyRecipes

Preheat oven to 350 °. Beat butter, granulated sugar, and vanilla at medium speed with an electric mixer until fluffy. Add egg, beating until blended. Combine flour and salt; gradually add to butter mixture, beating just until blended. Divide dough into 2 equal portions; flatten each portion into a disk. Cover and chill 10 minutes. Place 1 dough disk on a heavily floured surface, and roll to 1/8-inch thickness. Cut with a 3-inch heart-shaped cutter. Place 2 inches apart on lightly greased baking sheets. Repeat procedure with remaining dough disk. Bake at 350 ° for 10 to 12 minutes or until edges are lightly browned. Let cool on baking sheets 5 minutes; transfer to wire racks, and let cool completely (about 30 minutes). Whisk together meringue powder and 2 Tbsp. water. Brush cookies with mixture, or dip cookies in mixture, and sprinkle with sanding sugar. For jumbo cookies: Cut rolled-out dough with a 4 1/2-inch heart-shaped cutter.
