Place base ingredients into a food processor and pulse until crumbled and holding together.
Press this mixture firmly into a baking paper lined loaf pan (10cm x 20cm) and place into the freezer to set.
Then add all filling ingredients into a high speed blender or food processor and blend until completely smooth.
Take the loaf pan from the freezer and pour the filling into the pan. Place this back into the freezer, making sure it’s sitting flat on the shelf.
Freeze overnight.
Remove from pan and slice with a hot wet knife, store the slices in a container in the freezer. Take the slices out from the freezer 10 minutes prior to eating to come to room temperature.
