Feel free to add any additional extras (e.g. raisins, chocolate, peanut butter, marshmallows) in step two. These extras are really just limited by your imagination. In the past, I’ve found chocolate to be a real winner. It melts in the oven and oozes all over the place. Drizzle some over the top before putting it in the oven if you fancy, or cover them with a sprinkle of sugar. Just be creative with this recipe!
