  • Mixing Bowl
  • 8 x 8 pan


  • ½ cup salted butter room temp
  • ¾ cup brown sugar
  • 1 egg
  • 2 teaspoons vanilla
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 ¼ cups flour
  • 1 ½ cups white chocolate chips
  • ½ cup rainbow sprinkles
  • 2 Tablespoons rainbow sprinkles optional garnish


  • Preheat oven to 350 degrees F. Line an 8x8" baking pan with foil and spray with non-stick cooking spray.
  • In the bowl of a stand mixer fitted with the paddle attachment, mix the butter and brown sugar on medium speed for 2 minutes. Add the egg, vanilla, baking powder, and salt and continue mixing for 1 minute, scraping the sides of the bowl as necessary.
  • Turn the speed to low and add the flour, mixing until just combined. Stir in the white chocolate chips and 1/2 cup sprinkles until evenly incorporated.
  • Press the dough into the prepared pan, top with the additional 2 tablespoons of sprinkles, and bake for 20-25 minutes, until the edges are lightly golden brown.
  • Allow to cool in the pan on a wire rack.
  • Cut into bars when you're ready to serve.
  • Store airtight at room temperature for up to 3 days.
