Apple Banana Oatmeal Walnut Breakfast Bake – No Flour, No Added Sugar
Description
This Apple Banana Oatmeal Walnut Breakfast Bake is a wholesome, naturally sweet breakfast made with simple ingredients—oatmeal, milk, fresh apple, banana, eggs, and crunchy walnuts. There is no flour and no added sugar, yet the ripe banana and apple provide plenty of natural sweetness and flavour.
The texture is soft, hearty, and satisfying, somewhere between baked oatmeal and a breakfast cake. The oats absorb the milk and eggs during baking, while the banana adds moisture and natural sweetness. Chopped walnuts provide a delicious crunch and a rich, nutty flavour.
This recipe is perfect for busy mornings because it can be prepared ahead of time and enjoyed throughout the week. It can be served warm from the oven or cold from the refrigerator.
Important note: This recipe can be part of a balanced eating pattern, but no single food guarantees weight loss. Weight change depends on overall food intake, activity, sleep, health factors, and individual needs.
Recipe Information
Recipe Name: Apple Banana Oatmeal Walnut Breakfast Bake Prep Time: 15 minutes Cook Time: 35–40 minutes Total Time: About 55 minutes Servings: 6 Difficulty: Easy
Ingredients
1 cup oatmeal (approximately 90 g)
1 glass of milk (approximately 200–250 ml)
1 medium apple, chopped
1 ripe banana, sliced
3 large eggs
60g walnuts, chopped
Optional Flavour Additions
1 teaspoon vanilla extract
1 teaspoon ground cinnamon
¼ teaspoon ground nutmeg
Pinch of salt
1 teaspoon lemon juice
These ingredients are optional but can add extra flavour without requiring added sugar.
Instructions
Step 1: Preheat the oven.
Preheat your oven to 350°F (175°C).
Lightly grease an 8-inch square baking dish, small casserole dish, or loaf pan.
You can also line the dish with parchment paper to make removing and slicing the baked oatmeal easier.
Step 2: Prepare the Oats
Place the oatmeal in a large mixing bowl.
Pour the milk over the oats and stir gently.
Allow the oats to sit for approximately 5–10 minutes.
This soaking time helps soften the oats and allows them to absorb some of the milk before baking.
Rolled oats generally provide the best texture for this recipe. Quick oats can also be used, but the finished bake may be softer.
Step 3: Prepare the Fruit
Wash the apple thoroughly.
You can peel it if preferred, although leaving the peel on adds extra texture and fibre.
Remove the core and chop the apple into small pieces.
Slice the ripe banana into thin rounds.
If you are preparing the fruit in advance, toss the chopped apple with a small amount of lemon juice to help slow browning.
Choose a ripe banana for the best natural sweetness. The riper the banana, the sweeter the finished recipe will taste.
Step 4: Prepare the Walnuts
Roughly chop the walnuts.
You can use all 60 g inside the recipe or reserve a small handful to sprinkle over the top before baking.
For an even deeper nutty flavour, lightly toast the walnuts in a dry skillet for 2–3 minutes before chopping.
Allow toasted walnuts to cool before adding them to the mixture.
Step 5: Add the Eggs
Once the oats have softened, crack the 3 eggs into the bowl.
Whisk the mixture until the eggs are fully combined with the oats and milk.
The eggs are important because they help the breakfast bake set while adding protein and creating a soft, tender texture.
Add the vanilla, cinnamon, nutmeg, and pinch of salt if using.
Mix everything together.
Step 6: Add the Apple, Banana, and Walnuts
Add the chopped apple and most of the sliced banana to the oatmeal mixture.
Reserve a few banana slices for decorating the top if desired.
Add the chopped walnuts.
Gently fold everything together until the fruit and nuts are evenly distributed.
The mixture should be moist but not extremely watery.
If your oats absorb a lot of liquid and the mixture seems very dry, add a small splash of milk.
Step 7: Transfer to the Baking Dish
Pour the oatmeal mixture into the prepared baking dish.
Use the back of a spoon to spread everything evenly.
Arrange the reserved banana slices over the top.
Sprinkle the remaining walnuts over the surface.
If desired, add a light dusting of cinnamon.
Step 8: Bake
Place the dish in the preheated oven.
Bake for approximately 35–40 minutes.
The exact baking time may vary depending on your oven and the depth of the baking dish.
The breakfast bake is ready when:
The centre is set.
The eggs are fully cooked.
The edges are lightly golden.
The top feels firm when gently pressed.
If the top begins browning too quickly, loosely cover the dish with foil during the final part of baking.
Step 9: Cool and Serve
Remove the dish from the oven.
Allow it to rest for approximately 10 minutes before slicing.
The oatmeal bake will firm up slightly as it cools.
Cut into 6 portions and serve warm.
For a more filling breakfast, enjoy it with plain Greek yoghurt or cottage cheese.

Recipe Notes

Tips for the Best Results
1. Use Rolled Oats
Rolled oats create a heartier and more satisfying texture.
Avoid steel-cut oats unless you adjust the liquid and cooking time.
2. Use a Ripe Banana
A ripe banana provides more natural sweetness and a softer texture.
Look for a banana with yellow skin and some brown spots.
3. Chop the Apple Small
Small apple pieces cook more evenly and distribute throughout the bake.
Large pieces may remain firmer.
4. Don’t Overbake
Overbaking can make baked oatmeal dry.
Start checking around the 35-minute mark.
5. Let It Rest
Allowing the recipe to rest after baking makes it easier to slice into neat portions.
Storage and Meal Prep
