Notes
Clever Tip
Use very ripe, speckled bananas. They are sweeter, mash easier, and give the baked oatmeal a richer flavor, often reducing the need for extra sweetener.Meal Prep & Freezing Tips
- Prep Ahead: You can mix the dry and wet ingredients separately and store them overnight in the fridge. Combine them just before baking in the morning.
- Storage: Slice the cooled oatmeal into squares and store them in an airtight container in the refrigerator for up to 5 days.
- Freezing: Wrap individual cooled squares tightly in plastic wrap, then place them in a freezer bag. Freeze for up to 2 months. Reheat frozen slices in the microwave for 60 to 90 seconds.
