Finely chop all the ingredients for the base together with the water in a food processor. Pour the mixture into a shallow dish lined with baking paper measuring approx. 24 x 18 cm and smooth out. Chill in the fridge until ready to use.
For the caramel layer, soak the dates in warm water for 10 minutes. Then drain and blend finely in a food processor together with peanut butter and a pinch of salt. Roughly chop the almonds and fold into the date and peanut mixture. Spread evenly over the chilled base layer and chill for at least 2 hours. Then divide into approximately 9 x 2 ½ cm bars. Melt the chocolate in a bain-marie at a maximum of 45 °C to preserve the raw food quality. Dip the bars into the chocolate, allow to drip off briefly and then leave to harden completely in the fridge for 2 hours.
The bars will keep in an airtight box in the fridge for up to 14 days.
