4 oz (120 g) dark couverture/baking chocolate, chopped
1 cup (200 g) granulated sugar
2 large eggs, room temperature
1 tsp vanilla extract
⅓ cup (50 g) all-purpose flour
¼ cup (30 g) cocoa powder
½ tsp fine salt
¼ tsp baking powder
1½ cups (375 mL) coarsely chopped sweet treats, such as cookies, candies, chocolate bars, chocolate chips, etc.
10 to 12 large marshmallows, cut in half
Warm chocolate fudge sauce and/or butterscotch sauce, for serving
Directions
Preheat the oven to 350°F (180°C). Grease a 9-inch (23 cm) skillet or round baking pan well.
Melt the butter and chocolate together in a medium saucepan over low heat, stirring constantly until smooth and remove from the heat
Whisk the sugar into the pot followed by the eggs one at a time, and the vanilla. Sift in the flour, cocoa powder, salt and baking powder and add all at once, stirring until blended. Stir in 1 cup (250 mL) of the sweet treats and then scrape into the skillet or pan, spreading to level it.
Bake the brownie for 20 to 25 minutes, until the edges lift up and the top of the brownie loses its shine. Remove the brownie from the oven and increase the heat to 400°F (200°C). Arrange the marshmallows and remaining ½ cup (125 mL) of sweet treats on top of the brownie and return to the oven for about 5 minutes to brown the marshmallows.
Let the brownie cool in the pan on a rack for 15 minutes before drizzling with warm fudge and/or butterscotch sauce and spooning into bowls to serve. While best served warm, these brownies can be cooled in the pan (do not top with sauce), cut into squares and stored in an airtight container at room temperature for up to 3 days.
