For the Brownies

• Preheat your oven to 350°F.
• Spray a 9-inch square pan with baking spray or lightly butter and dust with cocoa powder, making sure to tap out any excess cocoa.
• In the bowl of a stand mixer fitted with the paddle attachment, combine melted butter (1/2 cup), white sugar (1/2 cup) and brown sugar (1/2 cup). This can also be done using a standard bowl and whisk.
• Once combined, add in eggs (2) and vanilla extract (1 tsp) and beat until it becomes smooth and pale yellow.
• Add in the flour (3/4 cup) and cocoa powder (1/2 cup). Mix just until no lumps of flour remain.
• Pour into greased pan and top with flake salt (1/2 tsp) and chopped penuts (1/3 cup). Bake on the center rack for 20 minutes.
• Remove the pan from the oven and top with chocolate chips (1/3 cup) and mini marshmallows (1 1/2 cups). Bake for another 10 mintes.
• Optional: Place the pan about 6 inches below the top of the oven and turn the broiler to high. Broil for 1-2 minutes or until the marshmallows are golden brown. Don't walk away-- they can burn fast!
• All the brownies to cool and set for at least 15 mintes before slicing. For clean slices, run a knife under hot water before each cut-- the marshmallows like to stick to the knife otherwise!
