I've been trying to make ice-cream over this summer.. this is my best effort yet.. it's delicious!!

2 handfuls cashews soaked overnight
1 frozen banana
1 tablespoon raw cane sugar (not sure if this is allowed but am sure you could use date paste or similar)
1 teaspoon cocoa powder

Blend the ingredients until smooth.
Eat straightaway or freeze. If you freeze, take out of the freezer a while before you want to eat it as it's rock solid!
