If your mornings feel like a race you are always losing, this recipe is about to become your best friend. High protein baked oats with Greek yogurt give you everything you need from a breakfast: real staying power, genuinely good flavour, and the kind of macro balance that keeps energy steady right through to lunch. One bake on Sunday and you have breakfast sorted for five days. No stirring over a stove, no complicated steps, no fancy equipment.
What makes this version stand apart from the usual baked oatmeal is the layered protein strategy. Greek yogurt goes directly into the batter, adding creaminess and a gentle tang while contributing a serious protein hit. Two whole eggs bind everything together and add even more. Chia seeds bring fibre, omega-3 fatty acids and a slight gel that helps the oats hold their shape once sliced. The result is a bake that is soft in the centre, lightly golden on top, and firm enough to slice into neat bars you can grab from the fridge. No protein powder needed here, because the protein comes from real whole foods that your body recognises and uses efficiently.
The sweetness is deliberately restrained. A single tablespoon of pure maple syrup and one ripe mashed banana provide all the sweetness this bake needs. The banana also adds potassium, natural moisture and a warmth that pairs beautifully with cinnamon and vanilla. Blueberries dot the top, bursting as they bake and creating little pockets of jammy fruit. You can absolutely swap them out for raspberries, diced apple or sliced strawberries depending on what is in season, but blueberries are particularly good here because their natural tartness cuts through the richness of the yogurt. Every slice comes in at around 210 calories with 22 grams of protein, 5 grams of fibre and only 6 grams of sugar, which puts it firmly in the category of genuinely healthy rather than healthy-ish.
Serving suggestions are where you can have a little fun. Cold from the fridge with a spoonful of almond butter and a scattering of extra blueberries is the classic move. Warmed for 60 seconds in the microwave with a dollop of extra Greek yogurt on top is equally wonderful on a slower morning. You could also crumble a slice into a bowl with some fresh fruit and a splash of oat milk if you fancy something closer to a granola bowl experience. However you eat it, this bake delivers the kind of breakfast that makes you feel like you actually have your life together, and sometimes that is exactly the energy you need to start the day right.
Ingredients
- 2 cups rolled oats (old-fashioned oats work best, not instant)
- 1 cup plain non-fat Greek yogurt (plus extra to serve if desired)
- 2 large eggs (room temperature)
- 1 medium ripe banana (mashed, about half a cup)
- 1 cup unsweetened almond milk (or any milk of choice)
- 1 tablespoon pure maple syrup (or raw honey)
- 2 tablespoons chia seeds (whole seeds)
- 1 teaspoon ground cinnamon
- 1 teaspoon pure vanilla extract
- 1 teaspoon baking powder
- 0.3 teaspoon fine sea salt
- 1 cup fresh blueberries (or frozen, not thawed)
- 2 tablespoons natural almond butter (optional, for topping when serving)
Instructions
- 1
Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit). Lightly spray or wipe an 8x8 inch baking dish with a little coconut oil or line it with parchment paper for easy removal.
Parchment paper makes slicing and lifting the bake much cleaner, especially for meal prep slices.

In a large mixing bowl, mash the banana thoroughly with a fork until almost no lumps remain. Add the Greek yogurt, eggs, almond milk, maple syrup and vanilla extract. Whisk everything together until smooth and well combined.
The more thoroughly you mash the banana, the more evenly the sweetness distributes through the bake.
- 3
Add the rolled oats, chia seeds, ground cinnamon, baking powder and sea salt to the wet mixture. Stir well with a spatula or wooden spoon until everything is evenly coated and no dry pockets remain. Let the mixture sit for 5 minutes so the oats and chia seeds begin to absorb the liquid.
This short rest helps the batter thicken slightly and ensures the bake holds together well after cooking.

Pour the oat mixture into your prepared baking dish and spread it into an even layer. Scatter the blueberries evenly across the top, pressing them in very gently so they sit just at the surface rather than sinking completely.
If using frozen blueberries, toss them in a teaspoon of oat flour first to prevent them from bleeding too much colour into the batter.
- 5
Bake in the preheated oven for 33 to 35 minutes, until the top is lightly golden, the edges are set and the centre no longer wobbles when you gently shake the dish. A toothpick inserted into the centre should come out mostly clean with just a few moist crumbs.
Every oven is slightly different, so start checking at the 30-minute mark to avoid over-baking and drying it out.
- 6
Remove from the oven and allow the bake to cool in the dish for at least 15 minutes before slicing. This resting time is important as it allows the structure to firm up so you get clean slices rather than crumbles.
For the cleanest slices and the best texture, cool completely and refrigerate for one hour before cutting. It is genuinely worth the wait.

Slice into 6 portions. Serve warm or cold, topped with a spoonful of extra Greek yogurt and a drizzle of almond butter if desired.

Pro Tips
- ✓
Use old-fashioned rolled oats rather than quick oats. Quick oats absorb liquid too fast and make the texture mushy rather than chewy.
- ✓
Full-fat Greek yogurt works if you prefer a richer result, though it will increase the calorie count slightly. Non-fat Greek yogurt keeps the protein-to-calorie ratio optimal.
- ✓
The riper your banana, the sweeter your bake will be without any added sweetener. Overripe bananas with lots of brown spots are ideal here.
- ✓
If you prefer a thicker, denser slice, reduce the almond milk to three-quarters of a cup. For a softer, more custardy texture, keep the full cup.
- ✓
This bake freezes exceptionally well. Wrap individual slices in parchment and freeze for up to two months for grab-and-go breakfasts.
Frequently Asked Questions
Variations
- •
Berry and Vanilla
Replace blueberries with a mix of raspberries and sliced strawberries. Add an extra half teaspoon of vanilla extract and a tablespoon of desiccated coconut stirred into the batter.
- •
Apple and Cinnamon
Replace blueberries with one small apple, peeled and finely diced. Increase cinnamon to one and a half teaspoons and add a pinch of ground nutmeg for a warming autumn flavour.
- •
Chocolate Cherry
Replace blueberries with fresh or frozen pitted cherries, halved. Add one tablespoon of unsweetened cocoa powder to the dry ingredients for a rich, brownie-adjacent baked oat experience.
- •
Banana Peanut Butter
Use two bananas instead of one and swirl two tablespoons of natural peanut butter through the batter just before baking. Top with a few banana slices and a light sprinkle of cacao nibs.
Substitutions
- •Greek yogurt → Thick coconut yogurt or high-protein soy yogurt (Use an unsweetened variety. The protein content will be lower with coconut yogurt, so check your label if macros matter to you.)
- •Almond milk → Oat milk, soy milk or regular dairy milk (Any milk works here. Soy milk will add a small protein boost. Dairy whole milk will increase fat and calories slightly.)
- •Maple syrup → Raw honey or a few drops of liquid stevia (If using stevia, reduce to just two or three drops and taste the batter before baking as stevia is significantly sweeter than maple syrup.)
- •Eggs → Two flax eggs (one tablespoon ground flaxseed plus three tablespoons water, rested for five minutes, per egg) (Flax eggs will make this vegan but the texture will be slightly less firm. The protein content will drop accordingly.)
- •Blueberries → Raspberries, diced strawberries, blackberries or chopped peaches (Frozen fruit works well. For very juicy fruits like peaches, pat them dry before adding to avoid excess moisture.)
- •Almond butter → Natural peanut butter, sunflower seed butter or tahini (Sunflower seed butter or tahini makes this nut-free while keeping the healthy fat content.)
🧊 Storage
Allow the bake to cool completely before storing. Slice into portions and layer between pieces of parchment paper in an airtight container. Refrigerate for up to 5 days. To reheat, microwave individual slices for 45 to 60 seconds. To freeze, wrap each slice individually in parchment paper and place in a freezer-safe bag or container for up to 2 months. Thaw overnight in the fridge or microwave from frozen for 90 seconds.
📅 Make Ahead
This bake is designed for meal prep. Make the full batch on Sunday and store slices in the fridge ready to grab each morning. It tastes just as good cold straight from the fridge as it does warm, which makes it genuinely convenient on busy mornings.
