  • 9 x 13" baking dish


For the Cookies:

  • 1 cup butter, softened
  • 3 oz. cream cheese, softened
  • 1/2 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 eggs, room temperature
  • 2 tsp. vanilla extract
  • 2 1/2 cups gluten-free all purpose flour, Bob's Red Mill 1 to 1
  • 1 tsp. baking powder
  • 1 tsp. salt
  • 1/2 cup sprinkles

Buttercream Frosting:

  • 1 1/2 sticks butter, softened
  • 2 1/2 cups powdered sugar
  • 1 tsp. vanilla extract
  • 1/4 tsp. salt
  • sprinkles for on top, optional


Making the Cookie Bars:

  • Start by preheating the oven to 350 degrees F.
  • In a large bowl, cream the softened butter and cream cheese together. About a minute.
  • Pour in both sugars and continue to beat on high until mixture is light and fluffy.
  • Next, add in the eggs and vanilla extract and mix well.
  • Pour in the flour, baking powder, and salt. Beat on high speed until everything is mixed well.
  • Pour sprinkles in and mix by hand.
  • Spray a 9 x 13" baking dish with cooking spray. Place cookie dough in dish and press dough to fit pan. Bake for about 20-25 minutes. Ours baked for 25 minutes and came out perfect. Keep an eye on yours so they don't overbake or burn.
  • Once cookie bars are out of the oven, let them cool completely before frosting them.

Making the Buttercream Frosting:

  • In a bowl using a hand mixer or stand mixer with the paddle attachment, cream the softened butter on high speed until it is smooth and creamy. About a minute.
  • Add to the butter the vanilla extract and salt and continue to blend on high speed until everything is blended well.
  • Add in the powdered sugar about 1/2 cup at a time so it doesn't make a huge mess. Blend on high speed until frosting is nice and smooth.
  • Frost the cookie bars with buttercream frosting and sprinkle colorful sprinkles over the top. Makes about 24 bars.
