Funfetti Blondies



  1. Preheat oven to 350 degrees and line one 9x9 inch pan with aluminum foil. Spray the foil with cooking spray.
  2. Mix together 1 tbsp of the flour with the rainbow sprinkles in a small bowl (this keeps them from bleeding too much into the batter!) Combine rest of the flour, baking powder, and salt in a bowl and whisk until well mixed.
  3. In the bowl of your stand mixer (or a large bowl with a hand mixer) beat both sugars and melted butter until smooth. Beat in eggs, one at a time, until fully incorporated, then beat in vanilla.
  4. On the slowest setting of your mixer, slowly stir the flour mixture into the butter/sugar mixture. Fold in the flour-coated rainbow sprinkles..
  5. Once the mixture is uniform, pour it into the prepared pan and bake at 350 degrees for 28-35 minutes, or until desired level of "doneness" is reached. (some people like their blondies a little undercooked, like yours truly!)
  6. Let cool in pan completely while you make the buttercream.
  7. Beat butter for a full three minutes until pale and fluffy, then beat in powdered sugar, one cup at a time, until frosting comes together. Beat in vanilla, followed by heavy cream (as needed) to adjust frosting consistency.
  8. Spread even layer of buttercream over top of cooled blondies. Top with additional lucky charms, if desired, and cut into bars.
