Add peanut butter, maple syrup and coconut oil to a small saucepan. Heat slowly until boiling, then simmer for 1-2 mins (stirring throughout). Allow to cool for 5 minutes before turning into a large mixing bowl.

Prepare a slice tin (approx 20cm square) with baking paper. Set aside

Add muesli to the mixing bowl, and combine well. Pour mixture into lined tin, then use a spoon to create an even slab. Set in fridge for 2+ hours, then cut into desired bar shape. Store in an air-tight container in the pantry.
