Double-Crunch Brownies

In a large bowl, stir butter, sugar and eggs.  Stir in cocoa, flour, vanilla and salt. 

Pour mixture into a greased 9-by-13-inch baking pan.  Bake for 25 minutes; remove from oven.

Carefully drop spoonfuls of marshmallow crème evenly over top of baked brownies. 

Return to oven 3 to 5 minutes to warm and then spread marshmallow cream evenly; set aside.

Melt peanut butter and chocolate chips in a medium saucepan over medium heat until smooth.  Stir in cereal until evenly coated.  Gently spread mixture over marshmallow crème.  Refrigerate before serving.
