Preheat the oven to 325 degrees and grease a 9 inch springform pan. You will need a large roasting pan that’s bigger and longer than the springform pan. (I use the aluminum foil disposable ones). If you are not sure about your springform holding up in water, you can wrap the outside of the springform pan in heavy duty aluminum foil from bottom up to the sides. I recommend wrapping the outside of the springform in foil before adding the crust and cheesecake batter.)
Crust:
Pulse cookies in the blender or food processor until it's all turned to crumbles.
Mix cookie crumbs with melted butter.
Spread crumb mixture in the bottom of the springform pan, evenly, pressing it over the bottom and a little up the sides.
Spread pulsed coconut flakes over the crust, loosely. Don't press.
Cheesecake:
In a bowl of an electric mixer, beat cream cheese on medium-high speed until smooth and fluffy, 2-3 minutes. Scrape sides and bottom of the bowl and beat for another minute.
Add corn starch and sugar and mix until combined.
Beat in eggs, one at a time, until well incorporated. Scrape sides and bottom of the bowl.
Add sour cream and cream of coconut and beat until all mixed very well.
Transfer the batter into the spring form and spread it evenly.
Place roasting pan into the oven and place cheesecake springform pan inside the roasting pan. Carefully add water to the roasting pan, about half way up the side of the springform.
Bake for 80-85 minutes. Turn off the oven and open the oven door half way. Let cheesecake rest for about 10 minutes and take it out of the oven (out of the roasting pan and carefully take off the foil).
Let it rest for 10 minutes on the counter and then gently run a greased butter knife between sides of the cheesecakes and the springform to carefully separate it. (You don't actually have to take the cheesecake out of the pan until ready to frost.)
Cool cheesecake for an hour and then place it in the refrigerator. Refrigerate for at least 4 hours before adding the frosting.
Frosting:
Beat cream cheese with an electric mixer for a couple of minutes.
Add sugar and cream of coconut. Scrape sides and bottom of the bowl and beat for about a minute.
Fold in whipped topping gently until all combined.
Spread a thin layer of frosting on the sides of the cheesecake so that the coconut flakes stick well.
Gently press pulsed coconut flakes onto the sides of the cheesecake.
Place the rest of the frosting into a piping bag and decorate the cheesecake as you wish. I used 1M attachment to make rosettes.
