Grease an 8x8 pan or equivalent using an oil spray.
On medium low heat, add coconut cream into a shallow heavy bottom pot. Bring to a simmer and stir intermittently with a wooden spoon until oil begins to separate.
Once the cream reaches a light tan color, continue to stir until bits start forming and turns to a light golden-brown color. Remove pot off the heat and set aside. The curd/bits will continue to brown a little.
While the pot is still hot, add marshmallows and stir until melted. Then add vanilla. Return pot to heat as needed to completely melt the marshmallows.
Place pot back on the stove and turn to low heat.
Add in Rice Krispies and kaki mochi in 2 stages, stirring and folding between additions.
Scrape contents into the greased pan. Gently form with the head of a spatula. Do not press down hard as the rice krispies will become dense.
Wait until it cools. Wrap well and enjoy within 2 days.
