Sugar Cookie Bars

I made these for a church social this summer and they were a huge hit!   The only problem is that all of my favorite things to make don't qualify as dinner or health food.  I found this recipe on Real Mom Kitchen's blog.

1 cup butter; room temp.
2 cups sugar
4 eggs
2 tsp. vanilla
5 cups flour
1 tsp. salt
1/2 tsp. soda

Cream butter and sugar until fluffy.  Add eggs, one at a time, mixing after each egg.  Add vanilla and mix well.  In a separate bowl combine flour, salt and soda and stir with a whist to combine.  Add to wet mixture and mix until just combined.  Spread on a greased baking sheet (use a 13x18 pan). Bake at 375 degrees for 10-15 min., until light golden brown or until a toothpick comes out clean.  Cool completely and frost.

Frosting
1/2 cup butter, room temp.
1/2 cup shortening
1 tsp. vanilla
pinch of salt
4 cups powdered sugar
5 tbsp. milk
food coloring (if desired)

For frosting combine butter and shortening until smooth and creamy. Add vanilla and salt.  Add powdered sugar in 1-2 cup increments until combined, then add milk and mix until smooth.  Spread over cooled cookie.
