Notes

Make Ahead and Leftovers: Baked peanut butter oatmeal can be stored at room temperature for up to 1 day, in the refrigerator for up to 4 days or frozen for up to 3 months.

Enjoy cold or reheat in the microwave or oven at 350 F for 5-10 minutes.

*Oats: I prefer the texture with large flake (old fashioned) rolled oats but instant or quick oats should both work as well.

**Protein Powder: I have tested this recipe with pea and rice proteins but suspect that it should work fine with most plain proteins. If you choose a sweetened/flavored powder, you will likely need to adjust the sweetener and I haven't tested that.

If you prefer to make it without protein powder, you can use oat flour instead. Simply pulse ⅔ cup of rolled oats in a blender until powdery.

***Sweetener: The honey can be increased to ½ cup for a sweeter baked oatmeal or decreased to ¼ cup for a less sweet option.
