Rinse out the food processor and dry ready to use again to prepare your filling.
Add your DF cream cheese, condensed milk and vanilla extract to the bowl of your food processor.
The thick layer of coconut cream that sits at the top of the tin is what we're after here. So scoop this out of your tin and measure out 1/4 cup before adding it to your food processor and other ingredients. If your coconut hasn't solidified on top as it typically does, pop it in the fridge until it hardens up. You don't want the watery cream at the bottom.
Pour the melted chocolate into the food processor as well and turn onto high to combine all the ingredients.
Stop every 30 seconds or so to scrape down the sides and incorporate all the ingredients. Then continue to blitz for a good minute until your mixture resembles a beautiful, silky, chocolatey mixture.
Remove your prepared base from the fridge/freezer and pour your filling into it. Smooth out gently to the sides and pop into the freezer (not the fridge) to set. This will take approx 4 hours.
