Here’s a list of everything you’ll need to make this Blueberry Almond Croissant Baked Oats recipe:
- 2 ripe bananas
- 1 & 1/2 cups oats
- 1/4 cup protein powder

Versatile Ingredients for Any Taste
One of the best things about this recipe is its flexibility; it’s easy to customise based on your preferences or what you have on hand.
For example, you could substitute the blueberries with raspberries or blackberries for a slightly different flavour profile.
You might also try adding a handful of dark chocolate chips for a richer, dessert-like variation.
The oats, bananas, and protein powder make this dish wonderfully filling, while the almonds and optional toppings allow you to add or adjust textures and flavours to suit your taste.

Why Frozen Blueberries Are Ideal for Baking
Frozen blueberries are an excellent choice in this recipe because they hold their shape better during baking and release their juices more gradually, infusing the oats with subtle tartness.
Using frozen berries also makes this recipe convenient for any time of the year, as they’re readily available and retain their nutrients beautifully.
When heated, they soften and add bursts of berry flavour throughout the dish, making each bite refreshing and delicious.
Plus, frozen berries are often more budget-friendly and can be stored for longer, making them a convenient and economical option for weekly meal preps.
The Role of Protein Powder in Baking
Adding protein powder to baked oats is a clever way to make this breakfast even more nutritious.
Protein powder doesn’t just provide essential amino acids; it also helps the dish to be more filling.
This is especially valuable for those with active lifestyles or anyone looking to stay energised through a busy morning.
The protein powder blends seamlessly with the flour and oats, enhancing the overall texture of the baked oats without overwhelming the flavour.
If you’re not a fan of protein powder, you could substitute it with additional oats or almond flour.

Perfecting Your Baking Texture
The texture of baked oats can vary based on factors like mixing time and ingredient consistency.
Mashing the bananas well and ensuring an even mix of dry and wet ingredients are key steps to achieving a balanced texture.
Additionally, overmixing can break down the oats too much, creating a mushy consistency.
For the perfect texture, stir just until everything is combined, allowing the oats to remain intact.
This technique results in a hearty and satisfying bite with every spoonful, where the oats and nuts retain their structure, making the dish both nourishing and texturally enjoyable.
How to Make This Recipe
Step 1: Mash the Bananas
Start by preheating your oven to 180 degrees Celsius.
In a baking dish, mash the two ripe bananas until they are smooth and free of lumps.
I really love using bananas in my baked oats whenever I can, because they not only add a natural sweetness to the dish but they also help to keep the baked oats moist and flavorful.
Additionally, they help keep the baked oats moist and soft, creating the perfect texture for a comforting breakfast dish.
Make sure to mash them thoroughly without leaving any large chunks so that they mix nicely into your base and build a nice solid foundation for your baked oats.

Step 2: Mix Dry Ingredients
Next, we’re going to mix together all of the dry ingredients, so go ahead and add 1 & 1/2 cups of oats, 1/4 cup of protein powder, 1/4 cup of plain flour, and 1 tsp of baking powder to the mashed bananas.
Mix these ingredients really well to ensure that the baking powder is evenly distributed, which will help our baked oats rise slightly in the oven and stop it from being too dense.
The protein powder adds fantastic nutritional boost, turning this hearty breakfast treat into a much more well rounded meal that will keep you fuller for longer.
Step 3: Combine with Wet Ingredients
The next step is to add all of our wet ingredients into the mixture.
Add 1 tbsp of maple syrup and 2 cups of oat milk to the dry ingredients and stir everything together until you get a well-combined batter.
The maple syrup adds a subtle sweetness that complements the ripe bananas, while the oat milk creates a creamy consistency.
Be sure not to overmix to maintain the structure of the oats and prevent them from becoming too mushy.

Step 4: Add Blueberries and Almonds
Gently fold in 1 cup of frozen blueberries into the batter, making sure they are covered by the mix. It’s important not to overmix at this stage to prevent the batter from turning purple.
The frozen blueberries will release their juices during baking, infusing the oats with a delicious tartness that will complement the sugary sweetness of the syrup perfectly.
Sprinkle a generous amount of flaked almonds on top. The almonds will toast beautifully in the oven, adding a delightful crunch to the dish.
Step 5: Bake and Serve
Place the baking dish in the preheated oven and bake for about 35 minutes, or until the top is golden and the oats are set.
Once baked, remove from the oven and let it cool slightly.
Top with a dusting of icing sugar, a dollop of vanilla yogurt, and an extra drizzle of maple syrup for added sweetness. Feel free to experiment with your favourite toppings to add your own twist to the dish!
These toppings add an extra layer of flavor and make the dish even more indulgent. Slice into portions and enjoy this warm, comforting, and nutritious breakfast treat.
