Preheat the oven to 180C and line a baking tray with parchment paper.
Place 125g of granola into a blender. Blend for a few seconds until it becomes flour like.
Add in 250g of peanut butter and 1 very large egg (or two small ones!). Mix together either with an electric hand mixer or with a wooden spoon.
Pour in your extra 55g of granola and mix thoroughly.
You should have a crumbly dough now. Using your hands grab a handful of the mix and mould it together into a flattened circle/oval. (Size wise, however big/thick you like your cookies - they won't change shape in the oven)
Place the cookies onto your baking tray and cook in the oven for around 15 minutes or until they are going slightly more golden.
Remove from the oven and allow to cool mainly on the baking tray before moving them onto a cooling wrack.
To make your peanut butter cookies PB&J cookies, heat up a little strawberry jam and place a dollop in the centre of each cookie.
