Learning how to make Gram’s sweet rice has been something my husband has talked about doing since the year we got married. After years of talking about making it, we finally sat down and hammered out our own version.

Some of the memories my husband had included stirring the rice (for hours), sprinkling copious amounts of cinnamon sugar on at the end, and popping little pats of butter into the rice just before serving. Of course he failed to recall the ingredients, steps, and quantities…

After a few failed batches we finally found our groove. We decided to keep some of these fun memories like poking butter into the rice while also ditching stirring the pot for what felt like hours.

This plant-based sweet rice recipe has all of the comfort of a traditional rice pudding without any of the dairy.

Why This Oat Milk Rice Pudding Works

After trying a variety of methods to make vegan rice pudding, we found the simplest way that resulted in thick, creamy, and flavorful sweet rice. The reason this oat milk rice pudding recipe works well includes:

1. The Rice Cooks First.

Unlike some of the methods we read about, this process for making sweet rice uses the same steps as cooking long grain rice to ensure you have chewy, not crunchy, rice in the end.

2. Oat Milk Doesn’t Curdle.

Unlike a traditional milk that needs continuous supervision so it doesn’t curdle on the sides of the pot during cooking, the oat milk can withstand the heat and needs less tending to.
