Choc-nut energy bars

Put the nuts, oats and seed and berry mix in a food processor and whizz to a chunky mixture. Add the remaining bar ingredients; whizz again until just combined. Transfer to a deep 20cm x 30cm tray lined with baking parchment and press into an even layer with the back of a spoon. Chill while you make the topping.

For the topping, break the chocolate into small pieces and melt with the coconut oil in a heatproof bowl, either in the microwave or over a pan of simmering water. Once melted, beat in the remaining ingredients until smooth.

Pour the chocolate over the nut mixture and spread with the back of a spoon until you have an even coating. Return to the fridge to set for about 1 hour, then cut into 24 squares. The bars can be stored in a sealed container in the fridge for up to 2 weeks.
