  • Preheat oven to 350F. Generously butter the sides and bottom of a 10" cast iron skillet and set aside.
  • In a KitchenAid or using a handmixer, beat butter until creamy.
  • Add in sugars and beat until light and fluffy.
  • Stir in eggs, one at a time, and then vanilla extract. Make sure to scrape the sides and bottom of the bowl periodically so the ingredients are mixed well.
  • In a separate bowl, whisk together flour, cornstarch, baking powder, and salt.
  • Gradually stir flour mixture into the butter mixture, until the ingredients are completely combined.
  • With your mixer on low-speed, stir in the sprinkles.
  • Pour out into 10" skillet and bake on 350F for 30-35 minutes (the edges should just be turning golden brown).
  • Allow to cool for 10 minutes or so. Top with ice cream, chocolate sauce, and sprinkles (if desired) and dig in! Be careful, though, the skillet will be very hot!
  • You may also allow the blondie to cool completely, and then slice into wedges and enjoy as is.
