Process all ingredients until well blended in a food processor. Transfer to a 5" springform pan (or a small tupperware container lined with parchment paper) and press down to flatten and compress and level out the top.
Freeze for 4-5 hours to set, then remove from pan, dust with extra lucuma powder (use a mesh sieve to sprinkle the powder evenly), cut into pieces, thaw out a bit and enjoy. Store leftovers in the fridge for a softer consistency or freeze for long term storage.
