Marshmallow Crispy Squares recipe

Here's the recipe!  It's very simple -  you only need 3 ingredients:

 45g butter

 300g mini marshmallows

 180g Rice Krispies

Melt the butter in a large pan, on low heat

 Add marshmallows and stir constantly until melted

 Take pan off heat, and immediately add cereal.  Mix lightly until well coated

 Place in tin.  Let cool completely before cutting.

* Since we couldn't wait until they had completely cooled to attack, I buttered the plate before placing the squares on it so that the marshmallow doesn't stick!
