How to Make It: No Frills, Just Good

Mash and Mix

Grab a big ol’ bowl. Mash your banana right in there. Crack in the egg, pour in the milk, syrup, vanilla, cinnamon, salt, and baking powder. Whisk that all together.

Dump in your oats. Stir. Fold in whatever else you’re adding—blueberries, chocolate, chopped apples, whatever feels good today.

Bake It

Grease a small baking dish. Pour in your oatmeal mixture. Bake at 375°F for about half an hour, give or take. It should be golden at the edges and just set in the middle. Soft but not soggy.

Cool for a few. Then slice. Scoop. Or just eat it straight from the pan. No judgement.

  • Can be eaten cold, but it’s way better warmed up

FAQs: You Asked, So Here’s What’s Up

Can I use quick oats?
Not really. The texture turns out mushy. Go rolled.

Is this good for meal prep?
Heck yes. Bake it once, eat all week. You can double the recipe for a crowd.

Can I make it vegan?
Yep. Use flax egg, non-dairy milk, and maple syrup or agave.

Can I freeze baked oatmeal?
Absolutely. Slice it, wrap it, freeze it. Reheat when needed.

How long does baked oatmeal last?
About five days in the fridge. But it usually disappears way faster.

Can I skip the banana?
Sure can. Sub applesauce or just use a bit more maple and adjust the texture.
