Servings 16

Ingredients

  • 3 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup salted butter softened
  • 1 ½ cups granulated sugar
  • 3 large eggs
  • 1 heaping Tablespoon sour cream
  • 1 teaspoon birthday cake extract (or vanilla) (I prefer this birthday cake extract)

FROSTING

  • 3/4 cup salted butter softened
  • 4 cups powdered sugar
  • 1/4 cup milk
  • 1 teaspoon birthday cake extract (or vanilla)
  • 1/4 teaspoon salt
  • Food coloring (optional)
  • Sprinkles

Instructions

Cookie Bars

  • Preheat oven to 350 degrees F. Line a 9×13 inch baking pan with parchment paper. Set aside.
  • Whisk the flour, baking powder, baking soda and salt together in a medium bowl. Set aside.
  • In a large bowl, or stand mixer, cream together the butter and sugar until light and fluffy; about 2 minutes. Add the eggs and combine well. Add the sour cream and birthday cake (or vanilla) extract; beat until combined. Gradually blend in the flour mixture just until combined.
  • Press dough evenly into the bottom of the greased pan with your hands. You can spray a little cooking spray on your hands so the batter doesn’t stick to them. Bake for 18 to 19 minutes only. Remove from oven and let cool completely before frosting.

Frosting

  • In a medium bowl, beat together the butter, 2 cups powdered sugar, and milk until combined. Slowly add in the remaining two cups of powdered sugar until combined. Add the birthday cake extract and salt.
  • *If you want color, add drops of desired color of food dye into the frosting and mix until fully blended and has reached desired color.
  • Frost with frosting and sprinkle with lots of sprinkles! Cut into bars and serve!
