Bars:
1 cup unsalted butter, room temperature
2 cups granualted sugar
4 large eggs
2 teaspoons vanilla extract
4 3/4 cups flour
1 teaspoon salt
1 teaspoon baking soda
In a large bowl, cream butter and sugar until fluffy. Add eggs one at a time, mixing after each egg. Mix in vanilla.
In a seperate bowl whisk together flour, salt and baking soda. Add to wet mixture and mix just until combined. Spread on a greased, rimmed baking sheet (13x8x1"). 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 mold the dough into the pan.
Bake at 375 degrees for 10-12 minutes, until light golden brown or until a toothpick comes out clean. Cool completely before frosting.
Frosting:
1/2 cup butter, softened
3 tablespoons milk
2 teaspoons vanilla
4 cups powdered sugar
A couple drops of food coloring
Combine all ingredients until well-blended. Spread on top of bars. Top if sprinkles if desired.
