Ingredients

For the Brownie Layer

1 cup sugar granulated
1/3 cup unsweetened cocoa powder measured and sifted
1/2 cup butter unsalted, melted
2 large eggs
2 teaspoons vanilla extract
3/4 cup all purpose flour spoon and level technique
1/4 tsp salt
1/3 cup dark chocolate chips

Marshmallow Topping

2 1/2 cups mini marshmallows
1/2 cup peanuts
1/4 cup semi-sweet chocolate chips

Chocolate Drizzle

1/4 cup butter melted, slightly cooled
3/4 cup powdered sugar sifted
1 tablespoon unsweetened cocoa powder
1 tablespoon whipping cream half and half or milk can be substituted

Instructions

Preheat the oven to 350°F. Line an 8×8 baking dish with parchment paper. Spray the parchment with non-stick cooking spray.
In a large bowl mix together flour, sugar, cocoa powder, and salt.
Mix in melted butter, eggs, and vanilla, combining until smooth.
Gently fold in chocolate chips and pour into the prepared 8×8 pan.
Bake for 30 minutes. Then remove from oven and top with the mini marshmallows, nuts, and chocolate chips.
Bake 4 to 6 minutes just to melt the marshmallows.
In a small bowl mix together the butter, powdered sugar, cocoa, and whipping cream. Add it to a zip bag and cut a tiny bit off the corner or piping bag with a little cut off the tip. Drizzle over warm brownies. Let cool before cutting.

Notes

Always hand mix the brownie batter. After combining the dry ingredients with a whisk, switch to a wooden spoon to mix the wet ingredients into the dry.
Don't over mix ingredients. Only mix until the flour disappears. This will ensure that the batter doesn't get over mixed.
Good quality ingredients. Using good quality ingredients will ensure you get the best brownies.
Use boxed brownies. If you are in a hurry, you can use a box mix to make the brownies. I included the directions above.
These brownies are RICH. A small square might not look like that much, but they are quite rich.
Make a double batch. Easily double the ingredients to make a double batch of this brownie recipe. Bake in a 9x13 pan.
Eat them warm. Reheat brownies in microwave for a few seconds for a warm treat.
