Kitchen Sink Cookie Bars

recipesfromfrenchcreek
everything but the kitchen sink chocolate chip cookie bars with a salty crunch of pretzels, m&m's, white chocolate, caramel bits and more. Like a traditional cookie bar, but better! These take no time to whip up and put in the oven. A fun dessert loved by many.
