Ingredients

  • 3/4 cup unsalted butter
  • 1 cup brown sugar packed
  • 1/3 cup granulated sugar
  • 1 large egg + 1 egg yolk room temperature
  • 1 1/2 teaspoon vanilla extract
  • 1 1/4 cup all-purpose flour
  • 3/4 teaspoon salt
  • 1/3 cup chopped walnuts
  • 1/2 cup Toffee bits

Instructions

    Cup of Yum
  1. Preheat oven to 350 degrees Fahrenheit. Line a 9x9 metal baking pan with parchment paper or lightly grease and set aside.
  2. Place butter in a medium-sized saucepan and cook over medium heat until melted. Once melted, turn up heat just a notch above medium and continue to cook, stirring constantly as it pops and sizzles. Once the popping slows and the butter begins to turn brown and fragrant, remove from heat and pour into a large heatproof bowl.
  3. Allow browned butter to cool for at least 20 minutes before proceeding.
  4. Once butter has cooled, add both sugars and mix to combine. Whisk in the egg and egg yolk, and vanilla extract. Mix to combine.
  5. Add the flour and salt and mix until combined. Fold in the chopped walnuts and toffee bits. Add to the prepared pan.
  6. Bake for 20-25 minutes, until the edges are golden brown and a toothpick comes out clean from the center. Let cool completely before serving.
