On top of stove combine the bag of marshmallows and peanut butter and warm up for less than five minutes on low temperature. You don't want the marshmallows all to melt. You just need them pliable and a bit sticky. You want the colour still to show through in the squares.

Remove sticky mixture from the heat and add all the granola in while stirring.

Add cranberries.

Scoop into a rectangular baking pan and pat down then let cool.

Cut into squares.

Enjoy!
