Blend first 5 ingredients in a food processor (I used my Vitamix). Dump onto your pan (I used a springform pan) and press down until firm. It should be crumbly but also sticky enough to hold. Set aside on the counter.
Blend the ingredients in a blender until smooth. (Make sure there is enough liquid to have the ingredients blend completely … add coconut water if needed, 1 T at a time) Pour filling into a bowl and fold in the remaining banana slices. Pour over the crust and smooth out.
