Rinse and prep your rice. Rinse under cold water until the water runs mostly clear. This helps keep your pudding from getting gluey.
Heat the milk and cream. Pour milk and cream into a medium saucepan over medium heat. Toss in the cinnamon stick and a pinch of salt. Warm until tiny bubbles form on the edges—no need to boil.
Cook the rice. Stir in the rinsed rice, reduce heat to low, and let it simmer gently. Stir frequently (or your rice might stick and sulk in the pan).
Sweeten the deal. Add sugar and vanilla extract after about 15–20 minutes, once the rice is soft. Keep stirring—it thickens gradually.
Check consistency. After 25–30 minutes, your pudding should be creamy but still spoonable. Remove the cinnamon stick.
Chill or serve warm. You can eat it hot, straight from the stove, or let it cool in the fridge for a few hours for that firmer, dessert-glow-up vibe.
