Ingredients

Scale

Main Ingredients

  • 1 stick + 5 tablespoons (13 tablespoons total) unsalted butter, melted
  • 1 1/2 cups dark brown sugar
  • 1 teaspoon vanilla or almond extract
  • 2 large eggs, at room temperature
  • 2 cups + 2 tablespoons all-purpose flour
  • 1/2 teaspoon salt
  • 1 teaspoon espresso powder
  • 1 cup toffee pieces (homemade or Heath Bar chips)
  • 1 cup milk chocolate or dark chocolate chips

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly grease it to prevent sticking.
  2. Cream Butter and Sugar: In a large bowl, combine the melted butter, dark brown sugar, and vanilla or almond extract. Mix until the ingredients are well blended and smooth.
  3. Add Eggs: Add the room temperature eggs to the butter and sugar mixture. Beat well until the batter is smooth and fully incorporated.
  4. Incorporate Dry Ingredients: Gently stir in the all-purpose flour, salt, and espresso powder. Mix carefully just until you see small traces of flour remaining; avoid overmixing to keep the blondies tender.
  5. Fold in Toffee and Chocolate Chips: Fold in almost all of the toffee pieces and chocolate chips, reserving about 1/4 cup of each to sprinkle on top later. This ensures even distribution throughout the batter.
  6. Pour and Sprinkle: Pour the batter evenly into the prepared pan. Sprinkle the reserved toffee pieces and chocolate chips on top for a delicious crunchy topping.
  7. Bake: Bake in the preheated oven for approximately 28 minutes, or until the top is golden brown and the center is mostly set but may have a slight wobble, if you prefer a gooey texture.
  8. Cool and Serve: Allow the blondies to cool in the pan before slicing into bars and serving to let them set perfectly.

Notes

  • Use room temperature eggs for better batter consistency and texture.
  • You can substitute Heath Bar chips for the toffee if desired.
  • The slight wobble in the center indicates a gooier blondie; bake longer if you prefer a firmer bar.
  • Line the pan with parchment paper for easier removal and cleanup.
  • Espresso powder enhances the chocolate flavor but can be omitted if preferred.
