Cookie Bars:
1 c. unsalted butter, room temperature
2 c. sugar
4 large eggs
2 tsp. vanilla
5 c. flour
1 tsp. salt
1/2 tsp. baking soda
Frosting:
1/2 c. unsalted butter, room temperature
1/2 c. shortening
1 tsp. vanilla
pinch of salt
4 c. powdered sugar (sift after measuring)
5 Tbsp. milk
food coloring, if desired
Preheat oven to 375 degrees. Spray a 13x18" jelly roll pan with cooking spray and set aside.
To prepare the bars: In a large bowl with an electric mixer, cream butter and sugar until fluffy. Add eggs, one at a time, mixing after each egg. Mix in vanilla.
In a separate bowl whisk together flour, salt, and baking soda. Add to wet mixture and mix just until combined.
Spread on the prepared baking sheet. The dough will be just like cookie dough - heavy and sticky - so it’s best to spray your hands with a little nonstick spray and use them to help mold the dough into the pan.
Bake for 10-15 min, until light golden brown or until a toothpick comes out clean. Cool completely before frosting.
To prepare the frosting: In a large bowl, beat butter and shortening together until smooth and creamy. Mix in vanilla and salt. Add powdered sugar, 1 cup at a time, until combined, then add milk & mix until smooth and of spreading consistency. Add a few drops of color, if desired. Spread over cooled cookie, then cut into bars.
Makes 32 bars.
