WOAH are these babies good! When I saw this recipe it automatically went on my "To Bake" list. I won't lie it has taken me a while to come back to these as my "list" is ever-growing. I wanted to use up what I had in my baking cupboards and I happened to have all of these ingredients on hand 🙂 YAY! And I have a kids birthday party to go to and I am going to work tonight so I can hopefully get rid of the whole pan so I don't sit and eat every last bite myself! Yes, I have done that before on many occasions :/

These bars are delicious and very rich! I like to cut the bars into small squares because they are so rich but any size will do! Enjoy!

    I have been dying to find a recipe that combined these ingredients. I often throw some marshmallows, PB chips and white chocolate chips together in a bowl and just snack on them together! Will definitely try this recipe!
