For the bars:

  • 1 cup unsalted butter (226 grams), at room temperature
  • 2 cups granulated sugar (400 grams)
  • 4 large eggs
  • 2 teaspoons vanilla extract
  • 5 cups all-purpose flour (625 grams)
  • 1 teaspoon salt
  • 1/2 teaspoon baking soda

For the buttercream frosting:

  • 1 cup unsalted butter (226 grams), at room temperature
  • 4 cups confectioners sugar (455 grams)
  • 1 tablespoon vanilla extract
  • 1/4 cup heavy whipping cream
  • Pinch of salt
  • Gel food coloring and sprinkles , optional


To make the bars:

  • Preheat oven to 375°F. Grease a 13 x 18-inch sheet pan (also known as a half sheet pan) and line with parchment paper.
  • With an electric mixture, beat together the butter and sugar until light and fluffy, about 3 minutes on medium high.
  • Add the eggs one at a time, mixing and scraping down the bowl after each. Add the vanilla.
  • In a medium bowl, combine the flour, salt and baking soda and set aside. Add to the rest of the ingredients in 2 additions, mixing until just combined.
  • Press the cookie dough into the sheet pan, using a greased spatula or parchment paper to spread it evenly. Bake for 14-17 minutes until lightly golden and a toothpick inserted into the middle comes out clean. Cool completely before frosting.

To make the frosting:

  • In the bowl of a stand mixer fitted with a paddle attachment, or in a large bowl with a hand-held mixer, mix all of the ingredients on low speed until it starts to come together.
  • Increase speed to high and beat for 4-5 minutes until frosting is fluffy, pausing once or twice to scrape the bowl down.
  • Add food coloring if using and mix until color is uniform.
  • Spread frosting over sugar cookie bars and cover with sprinkles, if desired. Cut and serve.
