Walnut and cacao bars

This is a rich but filling dessert, so a little piece goes a long way towards satisfying a craving.

3 cups walnuts
5 tablespoons cacao (or cocoa) powder
1 tablespoon chia seeds
10 fresh medjool dates, pitted and halved
1 tablespoon vanilla essence
Approximately 3 tablespoons coconut milk

Place the walnuts and cacao powder in a food processor and process until ground. Add the dates and vanilla essence and process. Add coconut milk slowly, until a sticky dough forms.

Remove the dough from the processor and mix in chia seeds.

Form the mixture into bars, place in an airtight container and store in the fridge.
