High Protein Baked Oats

Introducing your newest breakfast obsession! My Blueberry Almond Croissant Baked Oats will be your new favourite meal prep or weekend delight. Packed with protein, antioxidants and wholesome ingredients you most likely have in your pantry. It might be a mouthful to say but it couldn’t be easier to make or more delicious to eat.

Now, you might wonder, “What do these baked oats have to do with croissants?” You’re not alone – my inquisitive hubby asked the same thing! The inspiration comes from the classic almond croissant, which is filled with a sweet, rich Frangipane or Almond Cream. I decided to create a healthier version of that filling and swirl it into the oats, giving you all the flavours of an almond croissant without any compromise on taste. The result blew my mind and I know it will for you too!

You all know my love for Botanica Health protein powders They’re my secret weapon for boosting protein levels in recipes. And trust me, no one will even notice the extra protein in these oats! 

You can make these oats and eat straight from the oven using a big spoon to serve OR you can cut them into bars once they cool. I like to cut them into bars for quick breakfasts either on the go (we are all in a rush some days) or served with yogurt and of course my granola.

Everything You Need to Make Protein Baked Oats 

These protein baked oats are easy to make and require only a minimal amount of tools and ingredients that you most likely already have in your kitchen. You’ll need an 8×8 baking dish, some ripe bananas, and your favourite protein powder to get started!

Ingredients for Protein Baked Oats 

  • Banana: The banana serves as a natural sweetener and binder in this recipe, giving the baked oats a moist and tender texture. Packed with potassium and fibre; bananas help make this recipe nutritious and naturally sweet. If you’re not a fan of bananas, you can substitute them with applesauce or pumpkin puree, which will still provide that soft texture while adding a different flavour twist.
  • Egg or Flax Eggs: Bakers choice here, either eggs or flax eggs will work perfectly for this no fuss breakfast recipe. Eggs provide structure to the baked oats, helping them rise and stay together. Whether you use a traditional egg or a flax egg, both options ensure the oats hold their shape and have the perfect consistency.
  • Soy Milk: Going for the protein punch with soy milk as it helps provide plant based protein, a creamy texture and a slight nuttiness to the overall flavour.  Soy milk is also rich in calcium and vitamins, making it an excellent choice. Any other milk that you have on hand – plant based or cow based will work just fine in this recipe.
  • Almond Extract: Almond extract is a powerful flavour enhancer that gives the oats a sweet, nutty aroma reminiscent of almond croissants. It adds a layer of depth to the recipe, making each bite taste like a decadent treat.
  • Vanilla Extract: Perfevt in any oats recipe in my opinion; vanilla extract brings warmth and a comforting sweetness to the oats. It enhances the natural flavours of the other ingredients, making the oats taste richer and more complex. Vanilla is a classic addition that pairs perfectly with the almond butter and spices, creating a balanced and inviting flavour profile.
  • Butter: Melted butter plays a crucial role in the baked oats and the topping. It ensures a soft and flavorful texture for the baked oats. In the topping, it helps create a golden, crispy finish that contrasts beautifully with the fluffy oats. Whether you opt for dairy butter or vegan butter, this ingredient is essential for achieving that perfect bakery-style texture and buttery flavour. 
  • Almond Butter: To achieve the almond croissant flavour profile of course we need to work with some almond butter! It helps contribute a creamy, nutty richness to the baked oats that makes this dish absolutely irresistible. It’s packed with healthy fats, protein, and fibre, making the oats more filling and nutritious.
  • Gluten Free Oats: Oats are the heart of this recipe, providing a hearty, chewy texture that’s perfect for breakfast. Oats are naturally gluten free and rich in fibre, which helps keep you full and satisfied throughout the morning.
  • Ground Flax: Loaded with omega-3 fatty acids, fibre, and antioxidants; these mighty little seeds provide a subtle nutty flavour to the oats. They also help bind the ingredients together and are a great nutritional contribution to any breakfast. If you don’t have flax you can use ground chia seeds to achieve much of the same properties.
  • Baking Powder: Essential for giving the baked oats their rise, ensuring they are light and fluffy. It creates tiny air bubbles in the batter as it bakes, leading to a cake-like texture that’s both soft and satisfying. Without it, the oats would be dense and heavy, so this ingredient is key to achieving the perfect bake.
  • Nutmeg, Cinnamon & Ginger: This trio of spices add warmth and depth to the flavour. Cinnamon brings a sweet, woody note, nutmeg adds a hint of spice, and ginger gives a subtle zing. Together, they create a balanced and inviting flavour that complements the almond butter and vanilla perfectly.
  • Protein Powder: Protein powder boosts the protein content of these baked oats, making them a powerful breakfast option that keeps you full and energized. Whether you use vanilla or chocolate flavoured protein powder, it blends seamlessly into the batter, adding a rich, creamy texture without altering the taste. If you don’t have protein powder on hand, you can increase the almond butter or add Greek yogurt for an extra protein boost.
  • Salt: Brings out the natural flavours of the oats, almond butter, and spices, making each bite more flavorful and satisfying. Just a pinch goes a long way, so don’t skip this crucial ingredient.
  • Blueberries: Adding a burst of freshness and sweetness to the baked oats, making each bite delightful. They are packed with antioxidants, fibre, and vitamins, making them a healthy and delicious addition. As they bake, the blueberries burst, creating juicy pockets of flavour throughout the oats. If fresh blueberries aren’t in season, frozen ones work just as well, or you could substitute with raspberries or chopped strawberries.
  • Almond Flour: Keeping things gluten free; almond flour adds a subtle nutty flavour and a moist, tender texture to the baked oats. Almond flour helps to create a slightly denser, more satisfying bite, making these oats feel more like a decadent treat. You can substitute it with coconut flour, but keep in mind that coconut flour is more absorbent, so you may need to adjust the liquid content.
  • Maple Syrup: Maple syrup is a natural sweetener that adds a rich, caramel-like flavour to the recipe. It perfectly complements the almond butter and spices, creating a harmonious balance of sweet and nutty. Unlike refined sugar, maple syrup adds depth and complexity. If you’re looking to switch things up, honey or agave syrup are great alternatives that will still keep the oats perfectly sweetened.
  • Slivered Almonds: The essential addition to really bring the almond croissant vibes to life! Almond slices toast beautifully in the oven, adding a golden, slightly buttery taste that complements the creamy oats below. If you’re looking for a nut-free option, sunflower seeds or pumpkin seeds would also work well, providing a similar crunch.
  • Powdered Sugar (Optional): A dusting of powdered sugar is the finishing touch that makes these baked oats feel like a special treat. It adds a touch of sweetness without overpowering the other flavours, making the oats feel more like a dessert than a breakfast. While it’s optional, it’s a lovely way to add a bit of elegance and indulgence to the dish.

Are Oats Gluten Free? 

Oats are naturally gluten free, but they can often be cross-contaminated with gluten during processing. To ensure your baked oats are truly gluten free, opt for certified gluten free option – this should be clearly labelled on the packaging from a brand that you trust. This is particularly important for those with celiac disease or gluten sensitivities.

How to Make This Easy High Protein Baked Oats 

Start by preheating your oven to 350°F (175°C). While the oven is warming up, grease an 8×8-inch baking pan thoroughly with butter or non-stick spray. This step ensures that your baked oats won’t stick to the pan, making for easy removal and cleanup later on.

Mash the Banana and Mix the Wet Ingredients 

In a large mixing bowl, break up your ripe banana and use some good old elbow grease or an electric hand mixer to mash it until it’s relatively smooth with no large lumps. This gives the oats a naturally sweet base and a moist texture. Once the banana is mashed, add in the egg (or flax eggs for a vegan option), almond extract, vanilla extract, melted butter, and almond butter. Beat the mixture again until all the wet ingredients are fully incorporated and creamy. This blend of wet ingredients is key to achieving the perfect texture and flavour for your baked oats.

Combine the Dry Ingredients 

Next, it’s time to add your dry ingredients. Slowly mix in the gluten-free oats, ground flax seeds, protein powder, baking powder, and spices (cinnamon, nutmeg, and ginger). Gradually pour in your choice of milk (soy, almond, etc.) while mixing, ensuring that everything combines smoothly. The ground flax and protein powder help to bind the ingredients together while also boosting the nutritional content, making these baked oats both satisfying and wholesome.

Fold in the Blueberries 

Once your batter is well-mixed, gently fold in the blueberries using a spatula. The blueberries will add bursts of sweetness and juiciness throughout the oats as they bake. Be sure to distribute them evenly to ensure every bite is filled with that delicious blueberry flavour.

Prepare and Add the Topping 

In a small bowl, prepare the topping by mixing together almond flour, maple syrup, and almond butter until it forms a thick, crumbly mixture. Using two spoons, scatter this topping over the surface of your oats, making sure to cover it evenly. Finally, sprinkle sliced almonds on top to add a crunchy texture that will contrast beautifully with the soft, baked oats.

Bake and Cool 

Place your prepared pan in the preheated oven and bake for 40-45 minutes, or until the oats are set and no longer jiggly in the center. The topping should be golden brown, indicating that it’s perfectly baked. Once done, remove the pan from the oven and allow it to cool for about 10 minutes. This cooling period helps the oats to set further, making them easier to cut into squares or bars.

Serve and Enjoy 

Once cooled, cut the baked oats into squares and serve. These oats are delicious on their own but can be elevated further when served with a dollop of yogurt, a handful of fresh berries, and a sprinkle of your favourite granola. Enjoy them warm from the oven, or let them cool completely for a convenient grab-and-go breakfast or snack.

How to Store & Reheat Baked Oats 

Once baked, let the oats cool completely before cutting them into squares. Store them in an airtight container in the fridge for up to five days. To reheat, simply pop a square in the microwave for 20-30 seconds, or enjoy them cold – they’re just as delicious!

Making these baked oats ahead of time makes mornings so much easier, snack time delicious and answers the question of “What for breakfast?” in a flash! These protein baked oats are perfect for meal prep and you can bake them ahead of time and store them in the fridge for up to five days.

What to Serve With Baked Oats 

These baked oats are delicious on their own, but you can also pair them with a dollop of yogurt, a handful of fresh berries, or a drizzle of maple syrup. For an extra crunch, sprinkle some of your favourite granola on top.

    Your Blueberry Protein Croissant Oat recipe is absolutely delicious 😋 💯
    My whole family love it, and it will now be a regular breakfast option in my kitchen.
    Thank you, Teri-Anne for all your incredibly scrumptious recipes!! ❤️❤️

    1. Hey E, this is correct, this is for one serving however the macros really do depend on the specific products that you are using. This is just a slight generalization and if your nut butters, protein powders or any other products are lower in calories this will greatly change your macros. Please just consider these a generalization and not specific! You could always split the serving into smaller portions like I do!
