Line the bottom of a 4-inch cake tin with parchment paper.
To make the Base
Roughly chop the pitted dates in a food processor. Then add other ingredients and continue to process until the mixture is sticky and can stick together when you press them between your fingers.
Press the mixture into the bottom of the pan. Make sure you press them firmly so they can stick together. Then place it into the freezer while we make the fillings.
To make the Avocado Lime Filling
Blend all ingredients in a food processor until smooth.
Take out the pan from the freezer. Pour the filling mixture into the pan.
Gently drop the pan on the counter a few times to remove air in the filling and smooth the top. At this point, you can grate some lime zest on top too.
Place it into the fridge for at least 5 hours or overnight until it is completely set.
Remove it from the pan. Grate more lime zest on top. Slice and enjoy.
