Grease and line a spring form cake tin with parchment paper.
Mix the base ingredients together until the mixture resembles breadcrumbs.
Place the mixture into the spring form tin and press down evenly, with the back of spoon.
Bake for 20 minutes.
Remove from the oven.
Blend or beat the cream cheese, eggs, cream, sugar substitute, lime juice and rind together. I use a hand whisk but a hand blender or elbow power will do nicely.
Ensure that the mixture is smooth.
Pour the mixture over the walnut base.
Bake for 30-40 minutes until firm.
Allow to cool, then place in the fridge for at least 8 hours (or overnight).
Decorate as desired, eat and enjoy!
