No, you can't have just one. Or two for that matter...

Ingredients:

3/4 cup all-purpose flour
1 cup granulated sugar
3/4 cup unsweetened cocoa
1/2 cup packed brown sugar
1/2 teaspoon baking powder
1/4 teaspoon salt
1 cup bittersweet chocolate chunks, divided
1/3 cup milk
6 tablespoons butter, melted
1 teaspoon vanilla extract
2 large eggs, lightly beaten
1 16 oz package of marshmallows
1/2 cup chopped walnuts, divided

Cooking spray (used freely - or the brownies will stick horribly)

Directions:

Preheat oven to 350 degrees Fahrenheit. Lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 5 ingredients (through salt) in a large bowl. Combine 1/2 cup chocolate and milk in a microwave-safe bowl and microwave on HIGH for 1 minute, stirring after 30 seconds. Stir in butter, vanilla, and eggs. Add milk mixture, 1/2 package of marshmallows, 1/2 cup chocolate, and 1/4 cup nuts to flour mixture; stir to combine.

Pour the batter into a 9-inch square metal baking pan heavily coated with cooking spray; sprinkle with remaining 1/4 cup nuts. Bake for 45 minutes or until a wooden pick inserted in center comes out with moist crumbs clinging. Note: Brownies never seem done until they are cool. Don't be tempted to continue cooking if they seem too soft - these will be a little extra soft when first pulled out of the oven due to the marshmallows. Cool in pan on a wire rack. Only when fully cool, cut into small or large sized pieces. Large is obviously best, because small doesn't mean you eat less.
