Process all crust ingredients into a sticky crumble in a food processor. Transfer to a 4" springform pan (or make a few mini-cupcakes / use a lined small dish of a similar size) and press down into am even crust along the base. Place the pan in the freezer while working on the next step.
Blend all filling ingredients in a high-speed blender into a smooth consistency. Pour this mixture into the springform pan. Decorate with any toppings and freeze for 5-6 hours (or overnight) to set. Enjoy! Store leftovers in the freezer.
