Peanut Butter Not So Yummies

I like peanut butter ... and ... I like rice krispie squares. So I like to mix some peanut butter into the melting margarine when making rice krispie squares. Very Yummy. My sister loves these! (so does everyone I make them for) So for Easter dinner, I told her I would bring some squares for her. Made everything as per my version of the recipe. Which has ALWAYS turned out. That is, at least until this weekend. I had some extra marshmellows in the pantry. So I decided to add them to make the rice krispies extra chewy. However, the extra marshmellows were going a bit stale. I figured if I melted them, it wouldn't matter. Apparently it DOES matter. I could have sold these rice krispies as weapons! Holy hard batman! My sister still ate two of them. I'm not sure how in the world she swallowed them. Probably with a ton of saliva and a jaw of steel. Kim...remind me never to tell you to 'bite me' again.
