For the cookie bars:

  • 1/2 cup unsalted butter, room temperature
  • 3/4 cup sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1/2 tsp baking powder
  • 1/2 tsp sea salt
  • 1-1/2 cups flour

For the frosting:

  • 4 TBS unsalted butter, room temperature
  • 3 oz cream cheese
  • 1/2 tsp vanilla extract
  • 2 cups powdered sugar
  • Sprinkles for decorating


To make the cookie bars:

  • Preheat oven to 350 degrees and line a 9 x 9 square pan with aluminum foil or parchment paper.
  • In a large bowl, cream butter and sugar together until smooth and light colored.
  • Add egg, vanilla extract, baking powder, and sea salt and stir to combine.
  • Add flour, half at a time, and mix until just incorporated. 
  • Using the back side of a spoon floured well, gently press the cookie down into a lined baking pan. Continue flattening until it is even and all the way across the bottom of the pan.
  • Bake for 20 minutes, rotating halfway through. The edges will be slightly brown around the edges and the center may puff up slightly. This will settle when cooling.
  • Remove from oven and allow cookie bars to cool in the pan for 10 minutes before lifting out to cool completely.

To make the frosting:

  • In a medium bowl, using a hand mixer, cream butter, cream cheese, and vanilla extract together until fluffy and smooth.
  • Add powdered sugar, half at a time and mix on medium speed for 1-2 minutes until smooth and fluffy.
  • Using a frosting spatula, spread frosting evenly over cookie bars, slice, and serve. 
  • Store cookie bars in an airtight container for 3-4 days or freeze.
