I usually make something like this when I know I’m going to have a busy morning. Honestly, I love that I can mix everything together, put it in the oven, and have breakfast ready without standing over a pan.
The banana and apple bring plenty of natural sweetness, while the oats make the bake hearty and filling. The walnuts add a lovely crunch, and the eggs help everything hold together into soft, sliceable squares.
And despite the popular claim that a recipe like this will automatically make you “lose weight,” it’s worth keeping expectations realistic. No single food causes weight loss on its own. This recipe can certainly fit into a balanced eating plan, but portion size and your overall diet matter too.
Ingredients
Here’s what you’ll need:
- 1 cup oatmeal (rolled oats work especially well)
- 1 glass of milk (about 240 ml)
- 1 apple, chopped
- 1 banana, sliced
- 3 eggs
- 60 g walnuts, chopped
How to Make Oatmeal Apple Banana Bake
1. Prepare the oats
Preheat your oven to 180°C / 350°F.
Place the oatmeal in a baking dish. If you prefer a softer texture, you can soak the oats in the milk for about 5–10 minutes before adding the remaining ingredients.
2. Add the fruit
Peel and chop the apple into small pieces. Slice the banana and add both fruits to the oats.
I like cutting the apple fairly small so that you get little pieces of soft, sweet apple throughout every bite.
3. Mix the eggs and milk
In a separate bowl, whisk the 3 eggs with the milk until well combined.
Pour the mixture over the oats and fruit.
4. Add the walnuts
Scatter the chopped walnuts evenly over the mixture.
Give everything a gentle stir so the ingredients are distributed throughout the dish.
5. Bake
Place the baking dish in the preheated oven and bake for approximately 30–40 minutes, or until the center is set and the top is lightly golden.
Ovens vary, so start checking around the 30-minute mark. The bake should feel firm in the middle rather than wet or jiggly.
6. Cool and serve
Let the oatmeal bake cool for 5–10 minutes before slicing.
I find it cuts much more neatly once it has had a few minutes to settle.
Cooking Tips
Use rolled oats for the best texture
Rolled oats give this breakfast bake a pleasantly chewy texture. Quick oats will work too, but the finished dish may be softer.
Choose a ripe banana
A ripe banana adds more natural sweetness and makes the bake softer and more flavorful.
Don’t chop the apple too large
Small pieces cook more evenly and distribute the apple flavor throughout the oatmeal.
Watch the baking time
You want the center cooked through without drying out the edges. If your dish is deeper or smaller than a standard baking dish, the cooking time may change.
Toast the walnuts first
This is optional, but honestly, it’s one of my favorite little upgrades. Toast the walnuts in a dry pan for a few minutes before chopping them. It brings out their nutty flavor.
Add cinnamon if you like
The original ingredient list is wonderfully simple, but ½–1 teaspoon of cinnamon would be delicious with the apple and banana.
Serving Suggestions
This oatmeal bake is tasty warm or cold.
I usually serve a square on its own, but you can also add:
- A spoonful of plain Greek yogurt
- Fresh berries
- A few slices of banana
- A sprinkle of cinnamon
- A small drizzle of nut butter
- Extra chopped walnuts
For a particularly cozy breakfast, warm a slice for a few seconds before serving and add a little yogurt on top.
Can This Oatmeal Bake Help With Weight Loss?
This recipe contains nutritious ingredients such as oats, fruit, eggs, and walnuts, and it provides a combination of carbohydrates, protein, fat, and fiber.
However, “no flour, no sugar” doesn’t automatically mean “weight-loss food.” Oats, bananas, and walnuts still contain calories, and eating more calories than your body needs over time can prevent weight loss.
If you’re trying to manage your weight, pay attention to your portion size and consider the recipe as part of your overall eating pattern rather than relying on it as a special weight-loss food.

Frequently Asked Questions
1. Can I make this oatmeal bake without sugar?
Yes. The recipe contains no added sugar. The banana and apple provide natural sweetness. If your fruit isn’t very ripe, the finished bake will naturally be less sweet.

Yes. Water can replace the milk, although milk gives the oatmeal bake a creamier texture and adds protein and other nutrients.

Absolutely. You can assemble the mixture, cover it, and refrigerate it overnight. Bake it the next morning, allowing a little extra cooking time if the ingredients are cold from the refrigerator.
4. How should I store leftovers?
Let the oatmeal bake cool, then cover it and refrigerate. It should keep well for several days. Reheat individual portions in the microwave or oven.
5. Can I freeze oatmeal bake?
Yes. Cut the cooled bake into individual portions, wrap them well, and freeze. Thaw in the refrigerator and reheat before serving.
