Preheat the oven to 180 °C and lightly grease an 18 x 30 cm baking tin.
Place all the ingredients in a mixing bowl and mix until well combined.
Press mixture into the baking tin in an even layer and bake for 10-15 minutes or until golden brown and crispy.
Cut into 20 slices while they are still slightly warm. Allow to cool on a cooling rack and remove from the tin. Store in an airtight container for 3-4 days.
Serve 2 slices per person as a snack.
If pitted dates aren’t available, you can use raisins or dried cranberries.
Make sure you choose a good quality peanut butter that is lower in salt and sugar. Check the food labels and see page 12 for more detail on reading food labels.
