Berry baked oatmeal [refined sugar free]

This baked oatmeal is my go to breakfast when we, as a family, have an early start and I want something nutritious which is ready to go pretty much as soon as we come downstairs. And you know me, I just LOVE my breakfast!
Baked oatmeal is quick and versatile
I feel like I talk about this in nearly every post but what can I say? This girl loves quick and healthy recipes that allow for some wiggle room, creativity and can be changed based on what you have in your fridge or your pantry.
This baked oatmeal is definitely one of those dishes. Not only you will probably have all the ingredients at home already, the fruit you can use can include any berries, but also other soft fruits like plums, apricots or pears. Next time I am thinking of using rhubarb with some strawberries and I bet it will work beautifully.
I have made this lovely baked oatmeal with blueberries (the first and last photos) and strawberries (below) and they were both beyond delicious.
Plus, it’s a one bowl recipe. What’s not to love? Mix it all together, put it in the oven and wait for that delicious smell to spread through your house. What a fine breakfast dish for the weekend or, if you’re lucky enough, a weekday!

Breakfast oatmeal – a breakfast or a snack?
Another way in which this oatmeal is versatile relates to when and how you eat it – not only what you actually put in it. In other words, you might make it for Saturday breakfast and only eat half. The second half, cut into thick slices, will be a perfect snack for that Sunday hike, picnic, or a trip to the beach.
Feel free to share this lovely baked oatmeal with your family, including kids as young as toddlers. There is nothing hard in here for them to chew through, it’s a lovely soft slice full of gorgeous nutritious ingredients. And yes, no refined sugar, which is always fabulous for little growing bodies!
I even pack lovely fat squares of this in my kids’ lunch boxes on Mondays. For nut-free baked oatmeal, omit the flaked almonds on the top or use seeds instead (sunflower or pumpkin would be great).
Berry baked oatmeal [refined sugar free]
Ingredients
- 210 ml milk (dairy or plant-based)
- 2 small eggs
- 1/4 cup maple syrup or rice malt syrup
- 30 g unsalted butter, melted and cooled
- 1 medium to large banana (about 100g), mashed
- 1.5 cups whole oats (not quick cook oats)
- 1/2 tsp baking powder
- 1/2 tsp ground cinnamon (or speculaas spice mix)
- 1 tsp vanilla extract or vanilla paste
- 3/4 cup berries (blueberries, raspberries, blackberries, chopped strawberries etc)
- handful of flaked almonds (optional), for nut free omit or replace with seeds (pepitas or sunflower seeds)
Instructions
- Pre-heat the oven to 180C.
- Spray a square 20cm pan with coconut oil. You can line it with baking paper (optional).
- Mix all ingredients (except the flaked almonds) together in a large bowl, leaving the berries till last – stir them in gently when all the other ingredients had been mixed together well. You can also artistically strew the berries on the top over the mixture if you like, once it is in the pan.
- Pour the mixture into the prepared pan and top with berries (if not already mixed in) and flaked almonds or seeds, if using.
- Bake for about 35 minutes until golden and your house smells divine.
- Cool for 5 minutes before serving and then dig in!
Notes

Recipe notes and tips
While this is definitely a quick recipe to make, it is best not to make the mixture the night before and leave it in the fridge overnight. If you want to speed up the process in the morning, feel free to separately mix the dry ingredients and the wet ingredients, and all you will have to do in the morning is to mix those two together.
The cinnamon can be replaced with a speculaas spice mix for that extra delicious smell and taste and you’ll find the recipe here.
This recipe is based on a fabulous recipe from Sally’s Baking Addiction blog, which you can find here. I have halved my recipe as it suites our little family better and added the flaked almonds, otherwise I have followed her recipe very closely – no need to change what’s already fantastic!

I love the simplicity of this recipe, Katerina! I can already see myself saving the leftover for bar-shaped snacks! Great idea!
Katerina
Haha.. That’s what I do! Thanks so much, Laura!
Jeff the Chef
I’m glad I read your note about not mixing it up the night before, because that’s what I was thinking of doing as I was reading the earlier parts of your post. I love oatmeal. And I love that this one sounds so simple and straightforward. I love hot breakfast on a weekday and that’s what I was hoping I could do with this recipe. I also really like how versatile it is … how you were saying that you could take the leftovers for lunch with you. That sounds great.
Katerina
Thanks Jeff for reading my post so thoroughly! I really hope you enjoy this baked oatmeal!
Neil
I love a baked oatmeal breakfast. Most of mine are apple based so this version with all those yummy berries in is a delicious change. Thanks for sharing!
Katerina
Thanks Neil! I’d love to try an apple baked oatmeal, that sounds so delicious.
Shea
This looks really good! I don’t love the texture of regular oatmeal, but I tried it baked recently and I love it.
Katerina
It’s such an eye opener, isn’t it? Thanks Shea!
Marcie
Baked oatmeal is one of our favorite breakfasts, and blueberry is the best flavor in my book. I can’t wait till blueberries are back in season again!
Katerina
Isn’t it a wonderful combo? Thanks Marcie!
Ron
Wow, you may have just given me the recipe to get my wife to eat oats, she hates porridge (too many bowls as a child). I also love that you gave us a nut-free option as we’re a nut-free house. Oh, I think rubard and strawberry would be mighty tasty. Thanks for sharing and breakfast is also a favorite of mine so keep’m coming.
Katerina
If that works, Ron, I’ll be so happy for you! Oatmeal can be so wonderful but I hear you, negative food associations from childhood can also be very hard to overcome. Thanks so much, there are definitely more breakfast meals in the pipeline!
Laura Bambrick

I used to make baked oatmeal all the time for breakfast. In little ramekins, it’s great for meal prep. Your recipe has reminded me I need to revisit it for breakfast!
Katerina
What a great idea to make them in individual portions! I’ll have to give them a go, thanks Leanne!

Thanks for recommending not to make it ahead of time. That’s something I would do, but a great idea to mix up the ingredients before and just combine them in the morning. I love this kind of breakfast…easy and healthy.

Katerina
Thank you Jodie! Yes I don’t think it would come out terribly well, you’d basically have Bircher muesli 😊 Hope you get to make and enjoy it soon!
