For the base, blend together all ingredients until combined (don't over blend as the base is better a bit crumbly).
Line a round springform cake tin at the bottom only with baking paper and press the base into the tin, transfer into freezer while making the filling.
Cut avocados in half, remove seeds and scoop filling out, place in blender along with all remaining filling ingredients and blend until smooth.
Pour on the base the spread evenly with the back of a dessert spoon, place back into freezer for 3-4 hours.
Take out and add optional toppings! I used lime zest, lime slices, and pistachios!
Store in fringe or store in freezer if you want it to last longer!
Best eaten in 3-4 days.
Enjoy xx
