Healthy rice pudding

So i came across this recipe on pinterest and really wanted to try it. Its healthier than regular rice pudding and also looked really easy. i was really drawn to the fact that you didn't have to stand at the stove for hours stirring and stirring and stirring and waiting. So the recipe says to put everything together and put in the oven....well i have to admit that i don't like soy milk so much, so i used vanilla almond milk instead. so maybe thats what did it. But after i left it in the oven for the allotted time it was super liquidy still. so i sat it on the counter to gelatinize. well nothing happened. So i put it in a pot and proceeded to stir. after a while of stirring it finally gelatinized. So.  next time i will skip the oven all together and just use the stove.
