Turn plain cooked oatmeal into delicious baked oatmeal with this simple conversion recipe, plus 21 BONUS recipes filled with delicious flavor combinations! Also, try out my chocolate leftover oatmeal cake and blueberry baked oatmeal.

When the kids seem to tire of “regular” oatmeal, baked oatmeal comes to the rescue. I had been testing out a variation of carrot cake baked oatmeal, which the kids had devoured and asked for seconds. I wondered if I could somehow transform my bad oatmeal into a baked oatmeal dish, not having to waste the ingredients and create something edible… and dare I say, delicious.
As it turns out, regular overnight soaked oatmeal is not too far off from overnight baked oatmeal. A few of the steps are out of order, but once you figure that out along with the dry versus wet ratio, you’re good to go.
You can turn ANY regular oatmeal into a delicious baked oatmeal recipe with this method and as a bonus, not have to face the evil glare of the trash can at the end of the meal.
Here’s What You Need
- leftover soaked oatmeal, already cooked
- egg
- baking powder
- salt (if the original oatmeal wasn’t salted)
- butter or coconut oil
- banana
- vanilla extract (try my homemade recipe)
- cinnamon
- milk (optional)
- flavors (see below, for additional recipe ideas)
Psst! If you’re going to add salt, I highly recommend Ava Jane’s Kitchen. You may think all salt is created equal, but unfortunately, 90% of the salt produced around the world contains microplastics (gross, right?). Ava Jane’s Kitchen is an exception. Their salt is 100% microplastic-free, and it’s SO GOOD! Plus, you can get a bag for just 1¢!! (Get your penny bag of salt on this page.)
How to Make Easy Baked Oatmeal
Step 1. Preheat oven to 350F.
Step 2. Mash the banana in a large bowl and add cooked oatmeal.

Step 3. Add remaining ingredients and mix well. Add milk.
Step 4. Pour the oat mixture into a greased 8×8 or 9×9 baking pan and bake for 40-50 minutes, until golden brown. If desired, serve with fresh fruit and a drizzle of honey or maple syrup.
This delicious meal can last up to three days in the refrigerator in an airtight container.
Recipe Notes
- Many recipes call for sugar. I personally do not use any sugar in my regular soaked oats recipe and use maybe 2 Tbsp of sweetener per 8×8 or 9×9 square baking dish when I make this meal according to the recipe as written – even when it calls for much more. Instead, I rely on the natural sweetness of the fruit, dried and fresh, that we add to the recipe. This is an effort to keep our processed sugar intake to a minimum, but this has been a two-year journey in and of itself.
- If your family is new to real foods or isn’t too keen on oatmeal, take a cue from Mary Poppins, and don’t feel bad about using a little bit of sweetener to help the goodness go down. You can reduce the quantity you use in the recipes slowly over time, even if it’s just by 1/2 tsp with each recipe. Eventually, you’ll find the point of “just enough” sweetness and be able to balance it with the toppings your family has deemed as a favorite.
Tip: If you’re not sure if it’s “sweet enough” for your family, bake it anyway and allow a drizzle of pure maple syrup or honey to be a topping. The natural sweetness of these will be very prominent and make the recipe appear sweeter than it really is. Plus, these options are much healthier for you than the granulated sugar some recipes call for.
FAQs for Baked Oatmeal
Are baked oats good for weight loss?
Baked oats are a good source of fiber. Fiber can help you lose weight and prevent you from overeating.
Why are my baked oats soggy?
Baked oats may be soggy from not being baked long enough.
What oatmeal do you use for baking?
I use u003ca href=u0022https://dontwastethecrumbs.com/instant-pot-oatmeal/u0022u003ethis recipeu003c/au003e for oatmeal! It can be made in the Instant Pot.
Baking Options
- Most recipes call for oatmeal to be baked in square or rectangular dishes, but silicone muffin cups are a fun, single-serve option that doesn’t require greasing or buttering. You could even have a create-your-own caked oatmeal party like this family!
- Silicone muffin cups make clean-up SUPER easy. We have a set like these, which are perfect for regular-sized muffins. They also make mini-cupcake liners, bigger sizes like 3″ cups, 3.5″ cups, and even a 4″ jumbo liner. We try to use these to decrease our consumption of disposable ones, but they’re also great for other purposes too like making bars of lotion or single-servings of homemade fudge.
- Another option is to double the recipe and bake it in a 9×13 dish!
However, if you decide to make single servings, decrease the cooking time to 20-25 minutes.

The Healthy Breakfast Book by Katie Kimball is full of great breakfast ideas that DON’T include cereal, and she specifically highlights oatmeal in more ways than I have fingers. Plus the purchase comes with a few printables, one to note is the “10 Ways to Zoop Up Your Oatmeal.” VERY relative to today’s post, don’t you think?

So…I doubled this recipe, using chia seed egg instead of real eggs, but no other changes. I ended up with goo topped with a pool of coconut oil. What do you think happened?
It’s hard to say Brooke. I haven’t tested this recipe doubled, and I haven’t tested it with chia seeds instead of eggs as directed. How much milk did you add?
I can’t stand regular oatmeal, but I like baked oatmeal because the texture is different. Recently I made what I thought the kids would like – creamy buckwheat cereal. They HATED it, so little by little, I put it in pancake and baked oatmeal recipes. 🙂
That’s BRILLIANT Karla! I did something similar with a hot cereal that my kids didn’t like either too, but I just stuck it in plain oatmeal, lol. Baked oatmeal is much less conspicuous. 😉
These are incredible! Thank you for sharing! One quick question regarding soaking prior to cooking the oatmeal; if you use yogurt, can you leave it in a warm place for 7-24 hours? Should it be Greek yogurt or regular yogurt? I’ve been trying to make oatmeal that our family loves as much as instant (I know, silly, huh?), but I’ve been unable to do so. I want to try the soaking of the oats to see if that’ll improve the consistency I get when I regularly cook oats.
Thank you again for the blog and the incredible recipes!!
Holly
Yes! You can leave the yogurt in a warm place, and you can use whichever yogurt you happen to have. You’re most welcome Holly, and I’m glad you enjoy the recipes! 🙂
What a great idea. Will definitely share this! (As you can tell, I’m catching up on your posts I’ve missed while on vacation!) xo

Could I substitute the banana for something else? We are banana haters in our family. Maybe applesauce for sweetness? Or nut butter for thickening? Or a little bit of both?
I think a 1/2 cup of applesauce + 1 Tbsp of nut butter might do the trick. It’s mainly for sweetness and binding, so a combination would be best. Of course, feel free to experiment!!
This looks fantastic! Woud these freeze ok? I’m the only oatmeal eater in my family, so I like the idea of baking some in muffin tins and freezing, and also so I can have some cold with yoghurt over summer 🙂 thanks!
I bet it would! I’ve read others who make this and freeze it and re-heat for breakfast. Cold with yogurt or milk sounds YUM!
You’re most welcome Abi!!
I’m excited to try all these new recipes. I have a few that I usually make and my kids love them.
Great Shonda! Let us know which get two thumbs up!
Any thoughts on omitting the butter/oil? How would it impact the end result (besides reducing the fat content)?
Hmmm… personally, I wouldn’t do it for a few reasons. 1) Both butter and coconut oil are the good fats you want more of. 2) Butter adds a tenderness to the baked oatmeal. I think without it, the baked oatmeal would be a lot like a brick. 3) It tastes good. 🙂
Thanks for the response 🙂 Tenderness, huh…interesting. I know that when you omit fats from some baked goods, like muffins, they can get tough because gluten develops more freely. In something like baked oatmeal, where there are ostensibly no glutens to form, this wouldn’t be an issue, would it? Or maybe it has something to do with moisture and leavening. Hmmm…
As to whether butter and other refined fats are good for us and whether we should be incorporating more of them in our diets, I can happily agree that if eating them works for someone, then that’s great. It doesn’t work for my body, so I avoid them when possible.
It’s not a gluten issue, as you mention with oats not having any in the first place, but with the water/solid ratio in the fat. Butter (and coconut oil) are mostly water, which evaporates when baked and leaves behind little air pockets in the baked item – that’s what gives it the tenderness. The air replaces the leavening agent, giving it lift and separation. Think of when you bake a cookie – you cream the fat and sugar, adding air to give lift. When there’s no air, they turn out runny. Does that help with a visual?
Yes! Cooking science is so cool!
I have heard of using (unsweetened) applesauce to replace oils in baking. It is supposed to result in the same tender texture.
Sorry but I am a little confused about how much cooked oatmeal is in the baked oatmeal recipe.
So if I am using leftover cooked oatmeal ……. Is it 1 1/2 cups or 3 cups.
Cheers Marthea
Sorry Marthea! The conversion recipe written calls for 1 1/2 cups COOKED oatmeal. I’ll update the recipe to make it a bit clearer 🙂
