I LOVED making Better Homes and Garden Painted Sugar Cookies as a child and plan on making it a tradition w/ my daughter when she is old enough. They're sugar cookies that you "paint" with an egg yolk/food coloring mixture. Here's the recipe:
Cream together:
1 1/2 cup powdered sugar
1 cup butter
Add:
1 egg
1/2 tsp vanilla
1 tsp almond extract
Then add dry ingredients:
2 1/2 cup flour
1 tsp baking soda
1 tsp cream of tartar
Refrigerate dough 2-3 hours or more.
Roll out approx 3/16" thick and cut out into shapes with cookie cutters.
Paint with egg yolk paint (1 egg yolk + 1/4 tsp water + a few drops of food coloring) - we would always use cupcake pans and divide the yolk into six to make blue, green, yellow, red, orange, and brown. We also liked to add fun things like sprinkles for "lights" on X-Mas trees and red hots for Rudolph's nose, etc.
Bake 7-8 minutes.
