  • 1/2 cup (115 gm) unsalted butter
  • 1 cup (210 gm) dark muscovado sugar, packed
  • 1/2 cup (96 gm) sugar
  • 1/3 cup (80 mL) sunflower seed oil or other neutral oil
  • 2 large eggs, room temperature
  • 1 egg yolk, room temperature
  • 2 tablespoons milk, room temperature
  • 1 tablespoon vanilla extract
  • 11/2 cups (205 gm) bread flour
  • 11/2 cups (205 gm) all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 11/2 cups (180 gm) dark chocolate, chopped
  • Sea salt flakes for dusting on top, optional


  1. Preheat your oven to 375 degrees. Grease an 8×11″ casserole dish and line with parchment paper, letting the excess fall over the sides.
  2. Put the butter in a medium saucepan and melt over medium heat. Once melted, crack up the heat to medium high. Continue stirring and look for small golden bits that will start to settle on the bottom of the pan. It will smell deliciously nutty and caramel-y. This should take around 3-5 minutes. Once this happens, take it of the heat and pour into a medium, heat-safe bowl to cool a bit.
  3. When cooled slightly, whisk in the muscovado, granulated sugar, oil, eggs, egg yolk, milk, and vanilla until thoroughly blended.
  4. In another medium bowl, whisk together the bread flour, all-purpose flour, baking powder, baking soda and sea salt. Add this to the butter mixture and stir until barely blended. Add in the chocolate chunks and continue to blend until just combined and the chocolate is evenly distributed.
  5. Pour the mixture into the prepared baking dish. Dampen your hands and gently press down so that is covers the bottom of the dish. Bake in the center of the oven for 25 minutes. (Note: bake time is dependent on pan type and oven temp. If they look significantly gooey at 25 minutes, feel free to leave in an additional 5-10. Bars will continue to cook and firm up some once removed from the oven.) Sprinkle with sea salt flakes, if desired. Let cool completely before cutting. These are great the same day as they’re made and equally dazzling the next.


  • If you use a larger or smaller pan be sure to adjust your bake time accordingly. Additionally, these were tested in ceramic pans. Note, if you use a metal pan check earlier for doneness as it could affect the bake time.
