An easy variation :)
1 cup butter, softened (use ONLY real butter)
1/2 cup powdered sugar
1/4 cup corn starch
1-1/2 cups flour
Whip butter with an electric mixer until fluffy. Stir in remaining ingredients and beat on low for one minute, then on high for 3-4 minutes. Drop by spoonfuls on ungreased cookie sheet, about 2 inches apart.
Bake at 350 for 12-15 minutes Remove as bottoms begin to brown and cool on pan for 5 minutes before removing to wire rack.
