1. In a mixing bowl, beat margarine or butter and cream cheese with an electric mixer on medium to high speed about 30 seconds or until softened. Add about half of the flour, the sugar, egg, baking powder, and vanilla to the margarine mixture. Beat until thoroughly combined, scraping sides of bowl occasionally. Then beat or stir in the remaining flour.
2. Divide dough in half. Cover and chill for 3 to 24 hours or until easy to handle. On a lightly floured surface roll each portion of dough to 1/4-inch thickness. Cut into 2-1/2-to-3-1/2-inch shapes (such as tulips, flowers, or bunnies).
3. Place 1 inch apart on an ungreased cookie sheet. Tuck a wooden stick under the center of each cookie. Press dough down slightly so that the cookie bakes around the stick. Bake in a 375 degree F oven for 8 to 10 minutes or until edges are firm and bottoms are lightly browned. Carefully remove cookies and cool on wire rack. Makes about 36 cookies (fewer if larger cookie cutters are used).
Making the GlazeTo create colors, use a toothpick to transfer food coloring to the frosting. Add a tiny amount at a time until you find the color you want.
1. With a fork, beat together 2 tablespoons meringue powder, 1/4 cup warm water, and 2 cups sifted powdered sugar until smooth. Gradually stir in about 1-1/2 cups additional sifted powdered sugar to make a smooth glaze that is spreadable but not running. (It should have a flowing consistency and be too thin to hold ridges when spread.) Divide glaze; tint with paste food color as desired. Makes about 1 cup.
2. Place cookies on a cooling rack. When cool, spoon Meringue Powder Glaze over until covered.
3. Use a small food-safe brush to spread the glaze on the sides of the cookies. Allow the glaze to settle, then pick the cookies up and run a smooth knife over the back to knock off any drips before they harden. Let the cookies dry.
1. Combine meringue powder, water, powdered sugar, vanilla, and cream of tartar in a small mixer bowl. Beat with an electric mixer on low speed until combined, then on high speed for 7 to 10 minutes or until very stiff. Use at once.
2. Divide icing; tint with paste food color as desired. When not using icing, keep it covered with clear plastic wrap to prevent it from drying out. Makes 3 cups.
3. Fill a decorator tube with Royal Icing and make dots, squiggles, half circles, and stars on the cookies. Allow to dry completely.
