Place the coconut cream, ube ice cream and sugar in a sauce pan. Mix well then add in the cornstarch. Mix well again until the cornstarch has been fully mixed in and there are no lumps. Now turn on the heat to medium and cook for 5-7 minutes until the mixture starts to thicken and have a pudding like texture. It will look glossy and feel thick. Your whisk will also start to leave thin lines through it. Turn off the heat so it stops thickening.
Add in the Ube Halaya. Mix well. Add in ⅛ of a teaspoon of Ube Flavoring. Mix well. Transfer the Ube Pudding into a bowl. Then cover with plastic wrap making sure that the top of the pudding actually touches the plastic. This is so you don't get that weird rubbery film. Place in the refrigerator to cool down fully.
Make the whipped cream. Pour the cream into a bowl and add in ⅛ teaspoon of Ube Flavoring. We just want it slightly lavender so that when we add it to the pudding the color is not so diluted. Mix well. Then whip until the cream holds its shape. You can use a hand held mixer or just your arms. It's not much cream so it will whip pretty fast. Transfer to a bowl and cover and leave to chill until it's time to build.
Once everything is the cool, combine the Ube Pudding and whipped cream into a large bowl. Use a large spatula to fold it into each other. What you do is scoop from the top to the bottom in a flowing motion. This is to keep the air in the whipped cream so that your pudding is nice and light. Keep folding lightly until it is all combined.
Now it's time to build your Ube Banana Pudding! I decided to go with individual servings, but you can can use a 8x8 tray to make the pudding or a large truffle bowl. Start by lining the bottom with a Marie Biscuit. Then add on the sliced bananas. Be creative as you like with the placement. Next scoop in the first layer of Ube Pudding. I would say about 2 heaping tablespoons is good. Start your second layer with the Marie Biscuits. Layer the bananas on top and then more pudding.
Depending on the size of your serving container you can keep layering or stop. Smooth out the top or make a swirl. Then put in the refrigerator to chill until serving time.
