  • 1/2 cup (1 stick) unsalted butter, softened
  • 1/2 cup brown sugar packed
  • 1/2 cup granulated sugar
  • 1 egg
  • 2 teaspoons vanilla extract
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 and 1/2 cups all-purpose flour
  • 1/2 cup sprinkles


  • 1/2 cup (1 stick) 1 stick unsalted butter, softened
  • 2 teaspoons vanilla extract
  • 1/2 teaspoon salt
  • 3 and 1/2 cups powdered sugar
  • 1/4 cup milk of choice
  • sprinkles


  • Preheat your oven to 375 degrees F. Generously butter or grease a standard 9"x13" pan and set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl if using a handheld mixer, cream the butter and sugars together on medium speed until light and fluffy, about 2-3 minutes. Add the egg and vanilla and mix well.
  • Add in the baking powder and salt until well mixed. Turn the mixer to low and slowly add in the flour until no dry streaks remain. Add in the sprinkles.
  • Transfer the batter to your prepared pan and spread it out evenly, making sure you cover all the corners. Smooth out the top. Bake in your preheated oven for 15 minutes or until the tops and sides are golden brown. Allow the bars to cool completely.
  • While the bars are cooling, make the frosting. In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl if using a handheld mixer, beat the butter on medium speed. Add in the vanilla and salt. Turn the mixer down to low and slowly add in the powdered sugar about 1/2 cup at a time. Slowly stream in the milk and beat until smooth and creamy. Fold in the sprinkles last.
  • Once the bars have fully cooled, spread the frosting on top.


Bars should be stored in an airtight container at room temperature or in the refrigerator and will keep for several days.
