Author: Tricia


  • ½ cup unsalted butter, melted (113g or 4 ounces)
  • 1 cup light brown sugar, lightly packed (190g)
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 1 cup all-purpose flour (142g)
  • ¼ teaspoon salt
  • 1 cup chopped walnuts, divided (126g)
  • 1 cup toffee bits, divided (160g)


  • Preheat oven to 350 F degrees. Line an 8-inch square baking pan with parchment paper, or grease the pan.
  • In a large mixing bowl combine the butter and brown sugar. Mix with a wooden spoon or stiff spatula until well blended. Add the egg and vanilla. Add the flour and salt and stir well. Set aside 2 tablespoons each of the walnuts and toffee bits. Stir the remaining walnuts and toffee bits.
  • Spoon the batter into the prepared pan and spread evenly with a spatula. Sprinkle the reserved nuts and toffee bits on top.
  • Bake for 25 to 30 minutes or until a toothpick inserted comes out mostly clean with moist crumbs. Let the bars cool completely before slicing.
