Sugar Cookie Cake

  • 1 1/3 cups all-purpose flour
  • 1 teaspoon cornstarch
  • 3/4 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon kosher salt
  • 1/2 cup unsalted butter softened to room temperature
  • 1/2 cup granulated sugar
  • 1/4 cup light brown sugar
  • 1 large egg room temperature
  • 1 tablespoon milk
  • 1 tablespoon vanilla extract
  • 1/2 cup white chocolate chips
  • sprinkles optional


  • 1/2 cup unsalted butter softened to room temperature
  • 2 cups confectioner's sugar
  • 3 tablespoons milk
  • 1 teaspoon vanilla extract
  • 1/8 teaspoon kosher salt


  • Preheat your oven to 350 degrees F and spray a 9-inch pie dish with a non-stick spray. Set aside.
  • In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt. Set aside.
  • In the bowl of your stand mixer, with paddle attachment fixed (or with a hand held electric mixer), cream together the butter and sugars until smooth, creamy and fully combined, about 1 minute. Add the egg, milk and vanilla extract. Beat again, until incorporated.
  • With the mixer set on low speed, gradually add the dry ingredients to the wet. Mix until fully incorporated, about 1 minute. Fold in the white chocolate chips until evenly dispersed.
  • Pour the cookie dough into the prepared pan. Smooth over so that it is even. Bake at 350 degrees F for 25 minutes or until the top is lightly browned. The center should still be soft to the touch.
  • Remove from heat and transfer to a wire rack to cool completely before you frost the cookie.
  • Prepare your frosting by creaming together the butter and confectioner's sugar in the bowl of your stand mixer until fully combined, about 1-2 minutes. Add the milk, vanilla extract and salt and mix again for 1-2 minutes.
  • Frost the cookie cake once cool, sprinkle with sprinkles, cut into slices and serve!
  • The sugar cookie cake will store at room temperature in an airtight container for 3-4 days.
  • Enjoy!
