preparation Simply combine all of the base ingredients in a food processor, adding as much water as necessary to make a gooey and sticky base mixture. Line a 8x8 inch square cake tin with kitchen wrap and press the base in firmly, then freeze. Meanwhile start to work on your filling. To make the filling, simply combine the cashews and water in the food processor until it makes a smooth paste, then add the banana until well combined. Add the coconut oil, cacao powder and agave nectar and process until it is a smooth mixture. Pour it on top of the frozen base and return to the freezer, then cut into slices and enjoy!
