Ingredients

  • ¾ cup unsalted butter 12 tablespoons or 1½ sticks, divided and browned
  • ¾ cup brown sugar
  • ½ cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla
  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup semi-sweet chocolate chips
  • ½ cup toffee bits
  • ½ cup Nutella divided

Instructions

  1. Preheat the oven to 350°F and prepare an 8” or 9” square pan with parchment paper and cooking spray.
  2. Melt one stick (½ cup) of butter in a small saucepan over medium heat and stir until it turns golden and smells nutty. Turn off the heat, then pour it into a large bowl, being sure to scrape all of the brown bits on the bottom of the pan.
    ¾ cup unsalted butter
  3. Add the remaining ¼ cup of butter and whisk until all of the butter is melted.
  4. Add the brown sugar and granulated sugar, then whisk until smooth, then add the eggs, one at a time, making sure each one is incorporated before adding in the next. Whisk in the vanilla to combine.
    ¾ cup brown sugar, ½ cup granulated sugar, 2 large eggs, 1 teaspoon vanilla
  5. In a medium bowl, whisk together the flour, baking powder and salt.
    1 ½ cups all-purpose flour, 1 teaspoon baking powder, ½ teaspoon salt
  6. Transfer the dry ingredients to the butter mixture and stir to combine. Don’t overmix.
  7. Add the chocolate chips and toffee bits and mix in evenly.
    ½ cup semi-sweet chocolate chips, ½ cup toffee bits
  8. Spread about half of the batter to the prepared pan.
  9. Place the nutella in a heat safe dish and microwave for just about 10-15 seconds just to soften. Alternatively you can warm it on the stove over low heat.
    ½ cup Nutella
  10. Pour about half of the warm nutella over the top of the batter in ribbons and mix in slightly.
  11. Top with the remaining batter and spread out evenly over the first layer.
  12. Pour the remaining Nutella over the top in a ribbon then swirl it around a little bit with a knife.
  13. Bake for about 22-25 minutes. When they’re just set and golden brown on the edges but still a little soft in the middle, your bars are done.
  14. Let them cool completely to set, then cut and enjoy!

Notes

  • Set out all your ingredients before you start. Only the eggs need to come to room temperature since the butter gets melted.
  • When browning butter, it bubbles first, then foams. Once you see golden specks rising to the surface, it’s ready.
  • Add more chocolate chips, toffee bits or a pinch of salt on top before baking if you want a little extra.
  • For clean slices, make sure the bars are cold, use a big sharp knife and wipe it between cuts.
  • For thicker bars, bake the batter in an 8 inch pan and add a few extra minutes in the oven.
  • Line the pan with parchment and let it hang over the sides so you can lift the bars out easily.
