Allergens

  • Gluten
  • Peanuts
  • Soya
  • Oats count as a gluten cereal under UK labelling and ordinary oats are milled alongside wheat. Certified gluten-free oats are a separate ingredient here.
  • Flagged for the soya lecithin most bars use. Most also say they may contain milk and nuts.

Flags follow UK labelling rules and come from the ingredients as listed, not from any particular brand. Check the packet before cooking for somebody with an allergy.

Ingredients

  • Peanut butter40 g (a scant 3 tbsp)

Method

  1. Heat the oven to 180°C and line a tray with baking paper.

  2. Mash the banana and beat in the peanut butter until smooth, then stir in the oats, chopped chocolate and salt.

  3. Shape into six flattened rounds on the tray and bake for fourteen minutes until golden at the edges.

  4. Leave on the tray for five minutes before moving. They are soft when they come out and set as they cool.

Worth knowing

  • The peanut butter is most of the fat and the reason these hold together better than the banana-only cookie. Chocolate is a small share of the total; the oats and banana are the bulk.
  • Crunchy peanut butter gives a better texture here than smooth. The numbers are the same either way.
