Place prunes in a food processor or high speed blender and pulse until smooth. If your prunes are hard, you may need to soak them for 1-2 hours in water and heat them just a bit until soft.
In a double boiler melt the cacao paste.
Add the cacao paste and vanilla extract to the prunes and pulse to combine ingredients.
Roll the mixture into 1" balls then chill in the freezer for about 10 minutes.
To make the chocolate shell, melt the cacao butter and chocolate chips in a double boiler until smooth.
Remore truffles from the freezer and dip each one, one at the time in the melted chocolate and place them in a pan lined with parchment paper.
Place truffles in the fridge for just 10 minutes so the chocolate hardens and then store at room temperature.
Notes
Recipe makes 13 Chocolate Prune Truffles. I coated my truffles also with almond flour. If you do this, there is no need to place them in the fridge.
