Summer of Love S'mores Brownies

Ingredients

Crust:

• 6 tablespoons unsalted butter, melted
• 1 1/2 cups crushed graham cracker crumbs
• 2 Tbsp sugar
  
• Pinch fine salt

Brownies:

• 8 Tbsp unsalted butter
• 4 ounces unsweetened chocolate, chopped
• 1 cup packed light brown sugar
• 3/4 cup white sugar
• 1 1/2 tsp pure vanilla extract (I use Madagascar vanilla)*
• 1/2 tsp fine salt
• 4 large cold eggs
• 1 cup all-purpose flour

Topping:

• 4 cups large marshmallows

Directions

Position rack in lower third of oven and heat oven to 325 degrees F.
Line 8 by-8-inch square baking pan with foil so it hangs over the edges by about 1 inch.

For crust:
Lightly butter foil with some of melted butter. Stir rest of butter together with crumbs, sugar, and salt in medium bowl. Press crumb mixture evenly over bottom of pan. Bake until golden brown, about 20 minutes.

Brownies:
Put butter and chocolate in medium microwave safe bowl. Melt in microwave on 75 percent power for 2 minutes. Stir, and microwave again until completely melted, about 2 minutes more. Alternatively, put butter and chocolate in heatproof bowl. Bring saucepan filled with 1 inch or so of water to very slow simmer; set bowl on pan without touching water. Stir occasionally until melted.
Stir light brown and white sugars, vanilla, and salt into melted chocolate. Add eggs and beat vigorously to make thick and glossy batter. Add flour and stir until just incorporated.
Pour batter into prepared pan.
Bake until top is crispy and toothpick inserted into middle comes out mostly clean, with a few crumbs, about 40 to 45 minutes.
Remove from oven and carefully position rack about 6 inches from broiler and preheat on low.
Layer marshmallows across the top and toast under broiler until golden, (keep an eye on it, it can burn quickly), about 2 minutes. Or, use a small torch to brown the marshmallows.
Cool on rack, gently removing brownies from pan using aluminum flaps. Carefully separate any marshmallow from foil and fold away.
Cut into 12 (2-inch) squares.
