Sugar Cookie Bars

Cookie Bars
1 c butter, softened
2 c sugar
4 eggs
2 t vanilla
5 c flour
1/2 t baking soda

Preheat oven to 375°. In standing mixer fitted with paddle attachment, cream butter and sugar on medium high speed until fluffy. Add eggs, one at a time, mixing well after each addition. Mix dry ingredients together in a separate bowl. Add vanilla to the creamed mixture, then slowly add dry ingredients.

Press into a greased 13 x 18 inch pan and bake 20 to 25 minutes. Cool completely in pan before frosting.

Frosting
1/2 c butter, softened
1/2 c shortening
3 c powdered sugar
2 T milk
1 t vanilla

Cream all ingredients until well blended. Frost cookie bars and cut into squares. I used a pizza cutter with great success. Decorate with sprinkles, if desired.
