Some mornings just call for something you can grab straight from the fridge, eat without a fork, and actually feel good about. These healthy baked oatmeal cups with banana and blueberries tick every single one of those boxes. They are soft and lightly sweet, loaded with juicy blueberries in every bite, and they get their natural sweetness entirely from ripe banana and a small drizzle of pure maple syrup. No refined sugar, no weird ingredients, no fuss. Just real food that happens to taste like a treat.
What makes this version stand out from the crowd is the protein boost. Most baked oatmeal cup recipes lean heavily on oats alone, which gives you carbohydrates but leaves you hungry by mid-morning. Here, a generous scoop of plain Greek yogurt and two whole eggs work together to create a tender, moist texture while bumping the protein content up to around 8 grams per cup. That combination of complex carbohydrates from rolled oats, natural sugars from banana and blueberries, and satisfying protein means your blood sugar stays steady and your energy holds up all the way to lunch. The fibre content is strong too, with each cup delivering roughly 3 grams, thanks to the oats, chia seeds, and fruit.
The method is genuinely simple. You mash the bananas, whisk in the wet ingredients, fold everything together, and spoon the mixture into a lined muffin tin. The oven does the rest. One thing worth knowing is that using very ripe bananas, the ones with plenty of brown spots, makes a noticeable difference to the flavour. Ripe bananas are sweeter, softer, and they blend into the oat mixture far more smoothly than a firmer, less ripe fruit would. For the blueberries, fresh and frozen both work beautifully here. If you use frozen, do not thaw them first. Just fold them straight in from frozen so they hold their shape during baking rather than bleeding purple into the entire batter.
These cups are a meal prepper's best friend. Bake a batch on Sunday and you have breakfast sorted for the whole week. They reheat in the microwave in about 40 seconds, or you can eat them cold straight from the fridge if you are truly in a hurry. They also freeze brilliantly for up to three months, which means a little effort now translates into easy mornings for weeks ahead. Kids love them too, which makes them a genuinely useful recipe to have in your rotation. Serve them warm with a spoonful of almond butter on top, or alongside a small bowl of extra Greek yogurt and fresh fruit for a more substantial breakfast.
Ingredients
- 2 cups rolled oats (use certified gluten-free oats if needed)
- 1 tbsp chia seeds
- 1 tsp baking powder
- 1 tsp ground cinnamon
- 0.3 tsp fine sea salt
- 2 large very ripe bananas (about 200g peeled, the more brown spots the better)
- 2 large eggs
- 0.5 cup plain non-fat Greek yogurt (adds protein and keeps cups moist)
- 0.5 cup unsweetened almond milk (or any milk of choice)
- 2 tbsp pure maple syrup (adjust to taste based on banana sweetness)
- 1 tsp pure vanilla extract
- 1 cup fresh or frozen blueberries (do not thaw if using frozen)
Instructions
- 1
Preheat your oven to 190 degrees Celsius (375 degrees Fahrenheit). Line a standard 12-cup muffin tin with silicone liners or paper liners sprayed lightly with cooking spray. Silicone liners give the cleanest release.
Greasing the tin itself instead of using liners also works, but liners make removal much easier and keep the cups intact.

In a large mixing bowl, combine the rolled oats, chia seeds, baking powder, ground cinnamon, and sea salt. Stir everything together until evenly distributed.
- 3
In a separate medium bowl, mash the ripe bananas with a fork until smooth with very few lumps. Add the eggs, Greek yogurt, almond milk, maple syrup, and vanilla extract. Whisk everything together until well combined.
The smoother your banana mash, the more evenly the sweetness distributes through each cup.
- 4
Pour the wet mixture into the dry oat mixture and stir gently until everything is fully combined. Let the batter rest for 5 minutes. This gives the oats time to absorb some of the liquid so the cups hold together better.
Do not skip the resting step. It makes a real difference to the final texture.
- 5
Fold the blueberries into the batter gently using a spatula, being careful not to crush them.
If using frozen blueberries, work quickly and fold minimally to prevent the colour from bleeding too much into the batter.
- 6
Divide the batter evenly between the 12 prepared muffin cups. Each cup should be filled right to the top as these cups do not rise dramatically.
An ice cream scoop makes portioning fast and keeps the cups uniform in size.
- 7
Bake for 23 to 25 minutes, until the tops are set and lightly golden and a toothpick inserted in the centre comes out clean with no wet batter attached.
Ovens vary, so start checking at 22 minutes. The tops should feel firm to a light touch.
- 8
Remove the tin from the oven and allow the cups to cool in the tin for 10 minutes before lifting them out. This resting time helps them firm up so they come out cleanly without falling apart.

Pro Tips
- ✓
Use the ripest bananas you can find. Lots of brown spots means more natural sweetness and a softer texture in the final cups.
- ✓
Do not substitute instant oats for rolled oats. Instant oats absorb liquid differently and can result in a mushy, dense texture.
- ✓
For extra protein, stir a tablespoon of unflavoured protein powder into the dry ingredients before mixing. This adds roughly 3 to 4 extra grams of protein per cup.
- ✓
Press a few extra blueberries onto the top of each cup just before baking for a bakery-style appearance.
- ✓
Allow the cups to cool completely before stacking or storing to prevent them becoming soggy.
Frequently Asked Questions
Variations
- •
Peanut Butter Banana Blueberry Cups
Stir 2 tablespoons of natural peanut butter into the wet ingredient mixture before combining with the oats. It adds a rich, nutty flavour and an extra boost of healthy fat and protein.
- •
Lemon Blueberry Banana Cups
Add the zest of one lemon and a teaspoon of fresh lemon juice to the wet ingredients. The citrus lifts the blueberry flavour beautifully and gives the cups a brighter, fresher taste.
- •
Chocolate Chip Banana Blueberry Cups
Fold in 3 tablespoons of dark chocolate chips along with the blueberries. Use chips with at least 70 percent cacao for the most antioxidant benefit with less added sugar.
- •
Protein-Boosted Cups
Add one scoop of unflavoured or vanilla whey protein powder to the dry ingredients. This pushes each cup to around 11 to 12 grams of protein, making them a solid post-workout breakfast option.
Substitutions
- •Greek yogurt → Coconut yogurt or oat yogurt (Use the same quantity. Choose an unsweetened, thick variety for the best texture and to keep the sugar content low.)
- •Almond milk → Oat milk, soy milk, or regular low-fat cow's milk (Any milk works here in a one-to-one swap. The flavour will be very similar regardless of which you choose.)
- •Maple syrup → Raw honey or agave nectar (Use the same amount. If your bananas are very ripe and sweet, you may be able to reduce this to 1 tablespoon without noticing much difference.)
- •Rolled oats → Certified gluten-free rolled oats (A direct swap for anyone with gluten sensitivity. Do not use quick oats or steel-cut oats as the texture will not be the same.)
- •Eggs → Flax eggs (Combine 1 tablespoon ground flaxseed with 3 tablespoons water per egg. Rest for 5 minutes before using. Makes the recipe fully vegan.)
🧊 Storage
Store cooled oatmeal cups in an airtight container in the refrigerator for up to 5 days. Reheat individually in the microwave for 30 to 45 seconds. For longer storage, freeze for up to 3 months in a sealed freezer bag.
📅 Make Ahead
These cups are ideal for meal prep. Bake a full batch on the weekend and refrigerate for weekday breakfasts. You can also mix the dry ingredients and wet ingredients separately the night before, combine and bake fresh the next morning for a slightly quicker start.
