Materials

  • ¾ cup butter
  • 1 cup light brown sugar
  • ½ cup granulated sugar
  • 2 large eggs
  • 2 large egg yolks
  • 2 tsp vanilla extract
  • 1 ½ cups all-purpose flour
  • ¼ tsp baking soda
  • ¾ tsp salt
  • ¾ cup toffee bits check notes for my personal preference

Instructions

  • In a medium saucepan over medium heat, brown the butter by stirring until golden brown and nutty smelling, about 5–7 minutes. Immediately transfer to a large mixing bowl, scraping in all browned bits.
  • Whisk brown sugar and granulated sugar into the browned butter until smooth and glossy.
  • Whisk in eggs, yolks, and vanilla until well combined and shiny.
  • In a separate bowl, whisk flour, baking soda, and salt. Stir into wet ingredients but do not overmix. Fold in toffee pieces.
  • Spread batter evenly in a parchment-lined pan and bake at 350 F:
  • 8x8 inch pan for 28–32 minutes
    9×6.5 inch pan for 30-35 minutes
    9x9 inch pan for 25-30 minutes
  • until edges are set and the center is puffed but still slightly soft/jiggly. A toothpick should come out with moist crumbs, not raw batter.
  • Let blondies cool in the pan on a wire rack. For clean fudgy squares, cool at least 2 hours or chill before slicing.

Notes

Toffee pieces- I get the Heath toffee bits with milk chocolate. They have the regular toffee pieces w/o chocolate and they honestly taste chemically/weird to me. You can also chop up health bars yourself if you can't find what you need in the baking aisle.
