Measure out 1/2 cup of rolled oats and place them into a mixing bowl.
1/2 cup rolled oats
Add 1 cup of milk to the oats in the bowl, ensuring the oats are submerged.
1 cup milk
Stir in 1 teaspoon of vanilla extract and 1 tablespoon of honey or maple syrup, mixing until well combined and the oats are evenly coated.
1 teaspoon vanilla extract, 1 tablespoon honey or maple syrup
Cover the bowl with a lid or plastic wrap and place it in the refrigerator overnight, approximately 8 hours or until the oats have absorbed the liquid and become creamy.
In the morning, remove the oats from the refrigerator. The mixture should be thick, creamy, and slightly chewy, with visible flecks of vanilla on the surface.
Optionally, garnish with fresh berries, sliced bananas, or a sprinkle of cinnamon for added flavor and visual appeal before serving.
