In a mixing bowl or mason jar, combine rolled oats, milk, vanilla Greek yogurt, and maple syrup or honey. Stir well until fully incorporated.

Cover bowl or jar and refrigerate for at least 6 hours or overnight.

The next morning, stir the oats and scoop them into oven-safe ramekins.

Sprinkle a thin layer of granulated sugar on top of the oatmeal in each ramekin. Use a kitchen torch to caramelize the sugar.

Let the ramekins cool for about a minute before serving.
