Thank you for the recipe, joann_fla. I had to research what "coconut rum" is. lol!

I've kept searching myself (for days now) and have found a recipe on cooks.com that also seems to be similar to what I remember. They call it "X-23 Pina Colada Cheesecake". :)

X - 23 PINA COLADA CHEESECAKE
1 tsp. rum extract
1 (3 oz.) can flaked coconut
4 (8 oz.) pkg. cream cheese
5 eggs
1 1/4 c. sugar
2 tbsp. cornstarch
4 tbsp. melted butter
1 tsp. vanilla extract
1 tsp. lemon juice
2 c. sour cream
1 (20 oz.) can crushed pineapple, well drained
1. Heat oven to 400 degrees.

2. Place rum extract and coconut in food processor; process until combined and finely chopped. Set aside.

3. Place cream cheese in mixer bowl; beat until softened. Beat in the next 7 ingredients in the order above, beating well after each addition. Stir in the coconut and pineapple. Pour mixture into 9 inch springform pan. Place pan in large roasting pan; transfer to oven. Fill roasting pan with 1 1/2 inches hot water. Bake 30 minutes.

I can't believe that I wrote "Cheesecase", not once but TWICE in my original post, and never noticed it until now. lol! ...work was definitely on my mind.... ;^)

I noticed that Cheesecase, ha ha.
If you make the recipe you posted let me know how it turns out. The one I found seems kinda extensive. I never noticed the coconut rum either, I would use the flavoring myself.

One thing I do remember from the first time we made the original recipe is that the pineapple had a chemical reaction with my aluminum pan and caused "blackening" of the cheesecake wherever it touched! I'm thinking that the original recipe did not have a crust, but when we made it afterwards it did! :) And I learned to get it out of the pan ASAP after setting, because if left to sit long enough the crust would begin to blacken.

That's my one worry about trying to make it again... all of my cheesecake pans are aluminum, and it would be made for a function at work.

You can line your pan with parchment paper that might help it not blacken.

I was planning to try a parchment paper liner, so thanks for suggesting it.

They will probably want it at a self-serve dessert table for this function. I'm thinking that I should pre-cut it (leaving all pieces "in place") -- does that make sense, or would you just leave a knife & server with the whole cheesecake for people to cut whatever they choose?

I'll be making it next week and sure hope it comes out good!

I would pre cut the cheesecake. So many people take a big piece then never eat it. You can cut it then place the parchment between each piece. Let me know how it turns out. Or cut then lay out on a serving platter with the parchment separating each piece so they don't stick together.

Hello. I just wanted to post back that they kept changing the date of the function until they finally landed on a date that I couldn't do it. One of these days I'll make it though. Thanks for the help! :)

Sorry you couldn't make it. Maybe another function.
