  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup unsalted butter see notes below room temperature
  • ½ cup firmly packed light brown sugar
  • 6 tablespoons granulated sugar I used Zulka® Morena® Pure Cane Sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup semisweet chocolate chips
  • 1 cup vanilla chocolate chips
  • ½ cup sprinkles plus extra


  • Preheat the oven to 350°F and line z 9x13 pan with parchment paper or tinfoil and spray with non-stick spray.
  • In another large bowl, using an electric mixer at medium speed, beat together the butter, and sugars about 2 minutes and is smooth.
  • Add the eggs and vanilla and mix on low speed until mixed in.
  • Sift the flour, baking soda and salt over the wet mixture and mix together until just incorporated. Do not keep mixing - do not overmix.
  • Add chocolate chips, vanilla chips and sprinkles in, stirring with a wooden spoon, again no overmixing, just until incorporated. Dough will be very thick.
  • Spread thick cookie dough out evenly by dropping spoonfuls onto the baking sheet and spread out with fingers or it helps to spray a rubber spatula with non-stick spray. Dough will spread out while baking, so you don't have to get the corners and edges perfect. 
  • Sprinkle some extra chocolate chips and sprinkles to the top of the blondies. 
  • Bake for 20 to 25 minutes or until golden brown. Cool in pan on wire rack. 
  • After bars have cooled, lift the parchment paper out and cut the bars.Makes 12-15 dozen bars depending how big you make them.  Enjoy the party!
