From Nestle Toll House, a yummy dessert with a twist inspired by the popular ice cream:
2 cups (12 oz package) Nestle Toll House semi-sweet chocolate morsels, divided
1 1/2 cups all-purpose flour
1 1/2 tsp baking powder
1 cup granulate sugar
6 tbsp (3/4 stick) butter, softened
1 1/2 tsp vanilla extract
2 large eggs
2 cups miniature marshmallows
1 1/2 cups coarsely chopped walnuts
Preheat oven to 375F and grease a 13×9 inch baking pan.
Microwave 1 cup of the morsels in a medium, uncovered, microwave-safe bowl on HIGH (100%) power for 1 minute. Stir. Microwave in 10- to 15-second intervals if morsels are not completely melted. Cool to room temperature. Combine flour and baking powder in a small bowl.
Beat sugar, butter and vanilla in a large mixer bowl until crumbly. Beat in eggs. Add melted chocolate and beat until smooth. Gradually beat in flour mixture. Spread batter into prepared baking pan.
Bake 16 to 20 minutes or until wooden pick inserted in center comes out slightly sticky. While batter is baking, mix remaining 1 cup morsels, miniature marshmallows and walnuts in a bowl.
Remove baking pan from oven and sprinkle with morsels mixture. Return to oven for 2 minutes or until marshmallows being to puff and melt. Cool in pan on wire rack for 20 to 30 minutes. Cut into bars with a wet knife. Serve warm.
Serving suggestion: serve with plain vanilla ice cream on the side, or go fancy and add hot fudge or caramel sauce on top.
