In to a food processor place ground almonds, dried coconut, cashew butter, sweetener and salt and blend until a bound consistency has formed (about 1-2 mins)
In to a silicon mould or a greased dish press down the mixture to form a flat base. I like to keep mine about ½-3/4 an inch thick, but you can have it as thin / thick as you want!
Place in the freezer for about 30 minutes until solid
In to a glass bowl over a pan of boiling water melt your chocolate and coconut oil together, then add in your sweetener and stir in until fully dissolved (you can taste test to see if you're happy with the sweetness)
Now pour directly on to the shortbread base and place in freezer for about an hour until set
Remove from the freezer and allow to stand for about 15-20 minutes before using a sharp knife to cut squares
