What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a piece of parchment paper to press the oat mixture down firmly without sticking to your hands.
- 2For clean cuts through the chocolate layer, use a sharp chef's knife and wipe it clean between slices.
- 3Let the bars chill for the full 2 hours — rushing this step will cause them to fall apart.
- 4Store bars in an airtight container in the fridge for up to a week, or freeze for up to 3 months.
- 5If your peanut butter is thick, warm it with the honey just until pourable — boiling can make the bars dry.
- 6To speed up setting, place the pan in the freezer for 30 minutes instead of the refrigerator.
