Chocolate Peanut Butter Kit Kat Crunch Bars

"A soft, yet very chewy, rich, dense, peanut buttery base is topped with a crunchy chocolate topping that reminds me of a Nestle Crunch bar. There's Kit Kat candy bar pieces embedded, for extra crunch, texture, and flavor. Despite tasting extra buttery, there's no butter used. If you swap out the Kit Kats for peanut butter cups, the bars are vegan and gluten-free (since the Kit Kats are the only thing that's not vegan/GF in the recipe). If you need a fast and easy dessert that's sure to be a huge hit, I highly recommend these. They keep extremely well and can be made in advance, but I know leftovers will not linger. Quite possibly my favorite cereal bar of all time...."
