Yield: 24 bars
Cook Time: 30 minutes
ingredients:
1/2 cup butter, at room temperature
1 cup granulated sugar
3 large eggs, divided (1 egg, 2 yolks, and 2 egg whites)
1 teaspoon vanilla extract (I added this)
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
1/2 cup semi-sweet chocolate chips
1 cup mini marshmallows
1 cup chopped nuts (I left these out)
1 cup light brown sugar
directions:
1. Preheat oven to 350 degrees F. Grease a 9×13 pan and set aside.
2. In the bowl of a stand mixer, beat together butter and granulated sugar until creamy. Beat in 1 whole egg and 2 egg yolks (put aside the whites for later.) Beat in the vanilla extract.
3. In a separate medium bowl, whisk together the flour, salt, and baking powder. Add the dry ingredients to the wet ingredients. Blend until just combined. Spread mixture into 9×13″ pan. Sprinkle with marshmallows, chocolate chips, and nuts-if using.
4. Beat egg whites until stiff peaks form. Gently fold in the brown sugar. Spread mixture evenly over marshmallows and chocolate chips. Bake for about 30 minutes or until bars are a deep golden brown. Let bars cool completely. Cut into squares and serve.
