[ ] Rolled oats
3 cups
[ ] Milk
2 cups
[ ] Eggs
2 large
[ ] Banana, mashed
1 medium
[ ] Honey or maple syrup
2–3 tablespoons
[ ] Baking powder
1 teaspoon
[ ] Vanilla extract
1 teaspoon
[ ] Ground cinnamon
1 teaspoon
[ ] Salt
¼ teaspoon
[ ] Melted butter or coconut oil
2 tablespoons

– ½ cup blueberries or diced apples
– 2 tablespoons chocolate chips
Step-by-Step Instructions
Step 1: Prepare the oven and dish
Preheat your oven to 180°C (350°F). Lightly grease an 8-inch square or similar-sized baking dish with butter or oil.
Step 2: Mix the wet ingredients
In a large bowl, whisk together the eggs, milk, mashed banana, honey, vanilla extract, and melted butter until well combined.
Step 3: Add the dry ingredients
Stir in the rolled oats, baking powder, cinnamon, and salt. Mix thoroughly so the oats are evenly coated. Fold in any optional nuts or fruit.
Step 4: Fill the baking dish
Pour the oatmeal mixture into the prepared dish. Spread it evenly with a spoon and let it stand for 5 minutes so the oats can absorb some liquid.
Step 5: Bake until golden
Bake for 35–45 minutes, or until the top is golden brown and the center is set. A knife inserted in the center should come out without wet batter. The center should reach 71°C (160°F) because the recipe contains eggs.
Step 6: Cool and serve
Let the baked oatmeal rest for 10–15 minutes before cutting it into 9 squares. Serve warm on its own or with yogurt, berries, sliced banana, or a little honey.

Frequently Asked Questions (Q&A)
Q1: Can I make baked oatmeal without a banana?
Yes. Replace the banana with about ½ cup unsweetened applesauce. The flavor and texture will be slightly different.
Q2: Can I use water instead of milk?
Yes, water works, but the cake will be less creamy and contain less protein and calcium. Unsweetened plant-based milk is another option.
Q3: Can I use quick oats instead of rolled oats?
Yes. Quick oats work, although the texture may be softer and less chewy. Avoid steel-cut oats unless you adapt the recipe because they require more liquid and a longer cooking time.
Q4: Why is my baked oatmeal too soft in the middle?
It may need more baking time, or the dish may be too deep. Bake until the center is set, and allow it to rest for 10–15 minutes before slicing.
Q5: Can I prepare it the night before?
Absolutely! Mix the ingredients, cover the dish, and refrigerate overnight. Bake the next morning. You may need a few extra minutes of baking time if the mixture is cold.
Q6: How should I store leftovers?
Store cooled portions in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until hot throughout.
Q7: Can I freeze baked oatmeal?
Yes. Cut it into individual squares, wrap or store them in a freezer-safe container, and freeze for up to 3 months for best quality. Thaw in the refrigerator and reheat thoroughly.
Q8: How can I make this recipe higher in protein?
Use dairy milk or high-protein soy milk, serve with Greek yogurt, or add a little extra egg white. Protein powder can also be added, but you may need additional liquid to keep the oatmeal moist.
Q9: Is this recipe gluten-free?
Oats are naturally gluten-free, but cross-contamination can occur during processing. Use certified gluten-free oats if needed.
Q10: Can I make it without added sweetener?
Yes. Use a ripe banana and omit the honey or maple syrup. The finished cake will be less sweet.
Serving Suggestions
– Serve with Greek yogurt and fresh berries for a balanced breakfast.
– Add chopped nuts and cinnamon for extra crunch and flavor.
– Enjoy with a cup of tea or coffee as a wholesome snack.
– For dessert, serve warm with a spoonful of yogurt and a few dark chocolate chips.
Final Tips for the Best Results
– Use old-fashioned rolled oats for a hearty texture.
– Do not skip the resting time before baking or slicing.
– For a crispier, darker top, bake for a few extra minutes while watching carefully.
– For a softer cake, add 2–3 tablespoons of extra milk.
– Let the cake cool before storing to prevent excess moisture from building up.
