What is Overnight Baked Oatmeal?
If you’re used to stovetop oatmeal, you’re in for a treat. Overnight baked oatmeal is a heartier, more satisfying version of traditional oatmeal. Instead of cooking oats in a pot, they’re mixed with milk, eggs, sweeteners, and mix-ins, then left to soak before baking into a soft, cake-like texture.
Traditional Oatmeal vs. Baked Oatmeal
- Texture: Traditional oatmeal is creamy, while baked oatmeal is firmer, almost like bread pudding.
- Preparation: Regular oatmeal requires cooking on the stove, whereas baked oatmeal can be prepped the night before and baked in the morning.
- Convenience: Baked oatmeal is great for meal prep and reheats well.
