What oats are best for baking?
I used rolled oats in this baked oatmeal, and I find them the best for baking. They are whole, flatten oats that have a nice chewy texture. Quick oats are are similar, but they are cut into smaller pieces, so their texture is more delicate when baked. Old fashioned oats will result in a heartier texture.

Just a quick question for clarification purposes. The first part of your article mentions using brown sugar in your baked oatmeal recipe but the recipe doesn’t list brown sugar. Do you use the maple syrup instead of the brown sugar?
You’re so right – that’s an error. There is no brown sugar, just maple syrup. The recipe has been updated. Thank you for noticing that!
Whoops! Brown sugar is *still* listed in the “how to make…step-by-step section.
Ah, thank you for that catch! Awesome eye 🙂
Hi can I use honey instead of Maple syrup? 🙂
Absolutely!
Could you use frozen blueberries if thawed?
Yes. 🙂
I made this last night for this morning. I used 1/4cup of applesauce instead of butter and its delicious. A little crumbly but still taste great! Love this recipe
Delicious! I used flax in place of egg, as you suggested, with great results. I also substituted fresh raspberries in place of blueberries.
I’m so glad you loved it!
I used bananas instead of eggs, and also used fresh raspberries. To top it off I added a lemon drizzle. I DO NOT REGRET IT! So good!
This is so delicious and easy to make. Thank you for sharing with us all!
The taste is wonderful, I did think it spread a little thin. Did I do something wrong?
You could always try beating the egg a little more, so it rises higher. It’s not supposed to be super thick, so you could have done it perfectly!
This is really good! But mine came out very crumbly, any idea how to avoid this for next time? I followed the recipe exact, used butter instead of coconut oil. Thanks!
The coconut oil is a little bit of a better binder than butter, that could definitely be your issue!
Each helping is over 350 calories?
It is, which is definitely okay for a meal!
Would this work with just one egg?
One egg won’t hold it together as well, you could use just one egg but it will end up being more like granola then a solid sheet!
Of course I can’t find my 9×13 pan, and I had a bad mishap with a different recipe lately when I used the wrong size and ruined my meatloaf :(. Do you know if I make these in a muffin pan or something what the bake time would be? Sorry, I’m a novice but these look great.
I can’t say for sure what the timing would be, but you could always try it at 350 degrees for 20 minutes and then 5 minute increments after that! Let me know how it goes if you do it!
I tried them in a muffin tin (with paper wrappers). They were a bit greasy on the bottom from the coconut oil, but overall they held up well. I also put them in the freezer and pulled out a few every morning. It worked, but I think next time I’d rather just cut the big bake into sections.
I would definitely try that! That’s how we tested them so we can never say for sure if they’ll work in a different baking container 🙂
Hi, can you use instant oats instead of rolled oats?
Hi! We haven’t tested it with instant oats, but let us know if you try it!
