Ingredients:

  • 1 cup unsalted butter, cubed (plus extra for greasing)
  • 8 oz good quality dark chocolate (60-70% cocoa solids), chopped
  • 1 ½ cups granulated sugar
  • ½ cup light brown sugar, packed
  • 3 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup all-purpose flour, spooned and leveled
  • ¼ cup unsweetened cocoa powder (Dutch-process preferred)
  • ½ teaspoon fine sea salt
  • 1 ½ cups graham cracker crumbs (or digestive biscuits)
  • 6 tablespoons unsalted butter, melted
  • 2 tablespoons granulated sugar (for crust)
  • Approx. 4 cups large marshmallows (or 1 bag 10 oz)

Instructions:

  1. Preheat oven to 350°F (175°C). Lightly grease a 9-inch pie dish.
  2. For the crust: Combine graham cracker crumbs, 6 tablespoons of melted butter, and 2 tablespoons of sugar in a bowl. Press the mixture evenly across the bottom and slightly up the sides of the prepared pie dish. Bake for 8 minutes. Set aside.
  3. Gently melt the cubed butter and chopped dark chocolate together over low heat or in a double boiler until smooth. Stir well and allow to cool slightly.
  4. In a separate large bowl, whisk the granulated and brown sugars with the eggs until pale and slightly thickened (about 1 minute). Stir in the vanilla extract.
  5. Slowly whisk the slightly cooled chocolate mixture into the egg mixture until just combined.
  6. Gently fold in the flour, cocoa powder, and salt using a rubber spatula until just combined. Do not overmix.
  7. Pour the brownie batter evenly over the prepared graham cracker crust.
  8. Bake for 30–35 minutes. The edges should look set, and a toothpick inserted near the centre should come out with moist, fudgy crumbs clinging to it. Remove and allow to cool on a wire rack for at least 30 minutes.
  9. Arrange the marshmallows closely over the top of the cooled brownie layer, covering the entire surface.
  10. Place the pie under a preheated broiler (grill) set to medium-high. Watch constantly and toast for 1–3 minutes until the marshmallows are puffed and golden brown. Remove immediately.
  11. Let the S’mores Brownie Pie cool for 10 minutes before slicing and serving warm.
