There is something almost magical about the aroma of ripe bananas turning into a golden cake in the oven. From the very first bite, this Banana Oat Cake seduces you with its natural sweetness, soft texture, and wholesome charm. It’s a cake that manages to be both indulgent and guilt-free, making it a rare treasure in the world of homemade bakes. You don’t need fancy ingredients or complicated steps – just a few kitchen staples and ripe bananas that are probably already sitting on your counter. That’s part of the magic: it transforms everyday fruit into something that feels like a celebration.
This cake is flourless, relying instead on fine rolled oats to bring structure and heartiness, giving it a rustic yet elegant quality. The bananas bring not only natural sweetness but also moisture, ensuring each slice is tender and soft. A gentle touch of cinnamon adds warmth, while banana slices on top caramelise in the oven, creating a beautiful golden finish that is as stunning as it is delicious. It’s the kind of cake you’ll want to serve warm on a weekend morning, with coffee steaming beside you, or later in the evening with a dollop of yoghurt or a spoonful of nut butter. You’ll love how versatile it is: equally welcome at breakfast, teatime, or even as a light dessert. The simplicity makes it ideal for novice bakers, while the taste makes it a favourite among experienced ones too.
Unlike heavy, overly sweet cakes, this recipe balances indulgence with nourishment. Each slice feels satisfying yet light, never leaving you sluggish. It’s also perfect for sharing – something about the homely banana aroma draws people into the kitchen, ready to gather around the table. There’s comfort baked into every crumb, but also a spark of excitement. You never quite expect oats to become so tender, bananas to become so fragrant, and a handful of ingredients to deliver such joy. And once you’ve tried it, you’ll want to bake it again and again – because it’s not just a cake, it’s a little ritual of happiness.

👨🍳 How to Make It (Step-by-step)
✔️ Step 1: Preheat the oven
Preheat your oven to 180°C (350°F) and lightly grease a baking dish with butter.
💡 Tip: Greasing with butter adds flavour, but you can also line with parchment for easy removal.
✔️ Step 2: Mash the bananas
In a large bowl, mash 4 ripe bananas until smooth and creamy.
💡 Secret: Overripe bananas with dark spots are best – they’re sweeter and mash more easily.
✔️ Step 3: Add the eggs
Whisk in 2 eggs until the mixture is light and well combined.
💡 Tip: Room temperature eggs blend better and create a fluffier cake.
✔️ Step 4: Stir in dry ingredients
Add 1 cup of oats, 1 tbsp of baking powder, and a pinch of cinnamon. Stir until just combined.
💡 Secret: Don’t overmix – gentle folding keeps the texture soft and airy.
✔️ Step 5: Prepare the batter
Pour the smooth batter into the greased baking dish.
💡 Tip: Tap the dish gently on the counter to remove air bubbles for an even rise.
✔️ Step 6: Add toppings
Arrange banana slices on top for decoration and extra sweetness.
💡 Secret: A sprinkle of cinnamon sugar creates a caramelised finish.
✔️ Step 7: Bake
Place the dish in the oven and bake for 30 minutes, or until golden and set.
💡 Tip: Insert a toothpick – if it comes out clean, it’s ready.
✔️ Step 8: Cool slightly
Remove from the oven and let the cake cool for 10 minutes before slicing.
💡 Secret: Cooling slightly helps the cake firm up while staying moist inside.
✔️ Step 9: Slice and serve
Cut into squares or slices and serve warm or at room temperature.
💡 Tip: Warm slices taste divine with yoghurt, nut butter, or a drizzle of honey.
✔️ Step 10: Store leftovers
Transfer cooled cake into an airtight container for later enjoyment.
💡 Secret: This cake often tastes even better the next day as flavours deepen.
