Place the crust ingredients in a food processor and pulse until you have sticky crumbles.
Divide the crumble amongst 6 muffin/tart tins and press down evenly (with the bottom of a glass). Place in the freezer.
Place all filling ingredients in a high-speed blender and blend for 1 minute until completely smooth.
Divide the filling among the 6 tins and even out the top, then place in the freezer for min. 4 hours to firm up.
