Ingredients

Scale

For the Shortbread Cookies

  • 1 cup unsalted butter, softened
  • 0.75 cup powdered sugar
  • 2.25 cups all-purpose flour
  • 0.5 cup rainbow sprinkles

For the Frosting Filling

  • 1 cup unsalted butter, softened
  • 23 cups powdered sugar, sifted
  • 23 tablespoons milk or heavy cream
  • 1 teaspoon vanilla extract

Instructions

  1. Prepare Shortbread Dough: In a large bowl, cream together the softened butter and powdered sugar until light and fluffy. Gradually add the all-purpose flour and mix until the dough comes together. Gently fold in the rainbow sprinkles to evenly distribute them throughout the dough.
  2. Bake Cookies: Preheat your oven to 325°F (165°C). Roll the dough out on a lightly floured surface to about 1/4 inch thickness. Use a cookie cutter to cut out desired shapes and place them on a parchment-lined baking sheet. Bake for 15-18 minutes or until the edges are lightly golden. Remove from oven and allow the cookies to cool completely on a wire rack.
  3. Prepare Frosting Filling: In a medium bowl, beat softened butter until smooth and creamy. Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add milk or heavy cream a tablespoon at a time to achieve a spreadable consistency. Stir in vanilla extract and beat frosting until light and fluffy.
  4. Assemble Sandwich Cookies: Once the cookies have cooled completely, spread a generous amount of frosting on the flat side of one cookie. Sandwich with another cookie, flat side down, pressing lightly to secure. Repeat with remaining cookies.

Notes

  • Ensure the cookies are completely cool before frosting to prevent melting.
  • You can substitute rainbow sprinkles for other types of sprinkles or finely chopped nuts.
  • For a firmer frosting, refrigerate the frosting for 15 minutes before assembling.
  • Store sandwich cookies in an airtight container at room temperature for up to 5 days.
  • For crunchier cookies, bake a couple minutes longer but monitor carefully to avoid burning.
