Double Chocolate Marshmallow Brownies - cooking recipe

Ingredients

4 ounces unsweetened chocolate
1 cup butter
1 cup granulated sugar
1 cup light brown sugar
4 eggs
2 teaspoons vanilla
1/8 teaspoon salt
1 cup all-purpose flour, plus 1 tbsp if over 3000 feet
12 ounces semi-sweet chocolate chips
2 cups miniature marshmallows

Preparation

Melt the chocolate and butter together over double boiler (I just use a metal bowl over a pot of water).
Once melted, add both sugars and mix in until well blended. The sugars will not melt all the way, it will look gritty.
Take off double boiler and let cool about 15 minutes or until room temperature (you will scramble the eggs if you don't let it cool).
Using wire whisk, mix in eggs, one at a time, until well blended.
Add the vanilla, salt, and flour, and whisk until completely free of lumps.
With a rubber spatula, fold in chocolate chips and marshmallows, and pour into greased 9 x 13 pan.
Bake at 350 F for 35 to 38 minutes. Do not test for doneness, as the marshmallows will be melted at the top.
Dust with powdered sugar if desired.
