Here is my recipe for sugar cookies and icing. This is the least fussy recipe I know for sugar cookies. You don't even need to chill the dough so it is easy to work with.
Roll Out Cookies
1 c. butter
1 c. sugar
1 large egg
1 tsp vanilla extract
2 tsps baking powder
3 c flour
Preheat oven to 400 degrees. In a large bowl, cream butter and sugar with an electric mixer. Beat in egg and vanilla. Mix baking powder and flour, one cup at a time, mixing after each addition. The dough will be very stiff; blend last flour in by hand (if dough becomes too stiff, add water a teaspoon at a time.) Do not chill dough. Divide dough into 2 balls. On a floured surface, roll each ball into a circle, approximately 12 inches in diameter. Dip cutters in flour before each use. Bake cookies on an ungreased cookie sheet on top rack of oven for 6-7 minutes, or until cookies are lightly browned. Makes 20-24 average size cookies.
Poured Cookie Icing Recipe
This icing dries to a shiny, hard finish and tastes good too. It can be used for icing or to outline and fill in with a #2 or #3 tip.
1 c. sifted confectioner’s sugar
2 tsp. milk
2 tsp. light corn syrup
Place sugar and milk in a bowl. Stir until mixed thoroughly. Add corn syrup and mix well. For filling in areas, use thinned icing (add small amounts of light corn syrup until desired consistency is reached).
I tint the icing to the desired color with Wilton color paste.
