Common Ingredients for Baked Oatmeal
The main ingredients in baked oatmeal are typically oatmeal, eggs, and milk. We’re sharing other common ingredients below for you to stock up on!
Oatmeal: we’ve made baked oatmeal with both rolled oats and quick cooking oats. You can pretty much use them interchangeably. I’d say that rolled oats give you more of a “bite” kind of texture, where quick cooking oats are more muffin-like.
Eggs: eggs or an egg replacement like a flax egg are an important component when it comes to baked oatmeal. This is what gives the oatmeal the true muffin-like texture and it’s important you don’t skip this step!
Milk: Liquid is essential in baked oatmeal and we love using almond milk. The great thing is that you can use any kind of milk 1:1 such as cows, soy, etc.
Fruit: most baked oatmeal recipes call for some kind of fruit. I love adding pureed fruit like applesauce or mashed banana so that I don’t have to add as much (if any) oil.
Sweetener: our favorite sweeteners to use in baked oatmeal are maple syrup and honey. We like to keep things refined-sugar free, which is why we don’t use white sugar or brown sugar in our oatmeal bake recipes.
Flour: some baked oatmeal recipes call for flour and some don’t. I prefer to use a little bit of flour, whether it’s oat flour or white whole wheat flour, because this also helps with that yummy, bread-like texture.
Oil: Most baked oatmeal recipes call for some kind of oil and our favorite oil to bake with is coconut oil. Don’t forget to melt it before you mix it in!
Add-In Ideas
Every baked oatmeal recipe deserves a few add-ins to really spice things up and make them unique. Here are some ideas:
- chocolate chips
- fresh or frozen fruit

I tried to half this recipe because I didn’t want a whole 8 x 8 pan since it was just for myself. I put it in a bread pan. My batter was a little “thick” so I was worried it wouldn’t come out. It did and it tasted great – I added coconut, almonds, and raspberries.
So glad this worked for you!
These were great….I added coconut and chia seeds….they were hearty and just the right amount of sweetness.
These are amazing! The perfect grab and go snack or breakfast.
