Lucky Charms Marshmallow Crispy Treats

When I was a kid, there was one treat that always made its way into my lunch… Rice Crispy Treats.

Ingredients for Lucky Charms Marshmallow Crispy Treats spread out on table

You know the ones I’m talking about… they are wrapped in foil and taste like artificial chemicals. Still, as I kid I would eagerly gobble them up before forcing down the bologna + single-slice sandwich (kids of the early 90s, who can relate?).

Yesterday was one of those days where I craved the simplicity of being a kid again. Totally overwhelmed by my grown-up to-do list, I found myself dreaming about Rice Crispy Squares. Alas, the only cereal I had in my cupboard was Lucky Charms (thanks RCSS for the bonus cereal box!). It only made sense, with St Patrick’s Day coming up, that I would make a magically delicious version of the classic crispy treat.

Is there anything more magical and colourful than these? I don’t think so! So if you have any St Patrick’s Day plans for next week, it better include these treats!
