Dairy free rice pudding

I had another instance of leftover rice last night....so I made my dairy-free rice pudding. Which is healthier than standard rice pudding. It's hard to get a good custard with rice or soy milk without using some kind of thickener.
I came up with this recipe by accident...I was actually making some food for my sick dog last year and came up with the idea.
I think it tastes great and has more vitamins than standard rice pudding. Make it for yourself and let me know. You can substitute the soy creamer with milk, I just think it adds a little more richness to it. You can also use fresh sweet potatoes, just cook thoroughly in oven and scoop out meat of potato.

Recipe:
2 cups cooked rice (white or brown)
1 16 oz can sweet potatoes (drained and mashed)
1 cup soy or rice milk
1/2 cup vanilla soy creamer
1 tsp vanilla
1 tsp cinnamon
1/2 tsp nutmeg

Combine the mashed sweet potatoes with rice milk and soy creamer in saucepan over medium heat using electric beaters until almost smooth. (It's hard to get all the sweet potato lumps out). Heat for 10 minutes, add vanilla, cinnamon and nutmeg. Mix then add rice. Heat for another 10 minutes. If its not sweet enough you can add a splash of agave nectar.
