Cookie Bars

  • 1 cup unsalted butter, softened to room temperature 226g
  • 2 oz cream cheese softened 57g
  • 1 3/4 cup sugar 350g
  • 2 large eggs + 1 egg yolk
  • 1 teaspoon vanilla extract
  • 2 1/2 cups all purpose flour 285g
  • 1 /2 teaspoon baking powder
  • 1 teaspoon salt


  • 3/4 cup unsalted butter, softened to room temperature 170g
  • 1 1/2 cups powdered sugar 200g
  • 1/2 teaspoon vanilla extract

  • colored sprinkles for decorating (optional)


  1. Preheat oven to 350F (175C) and prepare a 13x9 pan by lining with parchment paper (or lightly grease and flour the pan). Set aside.

  2. Combine butter and cream cheese in the bowl of a stand mixer (or use a large bowl and an electric mixer). Beat together on medium-speed until well creamed (about 1 minute).
  3. Add sugar and gradually increase mixer speed to high, beating until well-combined and fluffy (about 1 minute).
  4. Add eggs and egg yolk, one at a time, stirring well between each addition. Scrape down the sides and bottom of the bowl as needed to ensure ingredients are well-combined.
  5. Stir in vanilla extract.

  6. In a separate, medium-sized bowl, whisk together flour, baking powder, and salt.
  7. Gradually add dry ingredients to wet, stirring on medium-low speed until completely combined.
  8. Spread batter evenly into prepared pan and bake on 350F (175C) for 25-30 minutes or until center is set and edges are beginning to turn light golden brown.. Allow cookie bars to cool completely in pan before covering with frosting.
