50g(1.8oz) dark chocolatechopped (check it's gluten free if required)
Preheat your oven to 170c/325f
Place the banana in a medium sized bowl and mash it with a fork. Add the oats, honey and peanut butter and give everything a good stir until combined.
Add in the chopped chocolate (reserve a few pieces to sprinkle on once the cookies are cooked) and the salt. Stir to combine.
Take a tbsp. of the mixture in your hand, roll into a ball and then squash to flatten into a thick disk (approx. 1cm thick). Place on a baking tray and repeat until all your mixture is used up. You should get 6-7 cookies.
Place in the oven and cook for 15 minutes.
Take out of the oven, sprinkle with the reserved chocolate and leave to cool.
