Naturally Sweetened Banana Cake With Oats
Moist, flavorful, and naturally sweetened, this banana cake with oats and dark chocolate is a wholesome twist on a classic favorite — made without flour, butter, and white sugar.
Perfect as a light breakfast, afternoon snack, or something cozy to share over coffee.
Welcome to Mikki’s Kitchen, my fellow cake lovers!
Today I’m sharing a lovely and healthy-ish treat: a banana cake with oats and dark chocolate.
If you’re looking for a cozy bake that feels indulgent but still brings some nourishing balance, you’re in the right place.
This banana cake with oats is the kind of recipe that makes use of those overripe bananas we often forget about. The spottier, the better! And trust me, once you try this, you’ll never toss a brown banana again.
I love baking this cake as a light afternoon treat, a breakfast on the go, or something sweet to share with friends over coffee. It’s naturally sweetened with ripe bananas, filled with hearty oats, and made extra delicious with melty dark chocolate chunks.
Simple and no-fuss, this bake still brings wholesome energy to the table. The oats add fiber, the eggs give a bit of protein, and the bananas do most of the sweetening — no need for refined sugar.
Altogether, a feel-good favorite if you ask me!
And the best part? This banana cake comes together with just a few pantry staples. A quick blend with a stick blender or food processor is all it takes to turn it into a smooth, dreamy batter. Then, fold in the chocolate chunks, and you’re ready to bake.
How Many People Does This Banana Cake With Oats Serve?
This banana cake recipe makes a good mid-sized cake that serves around four to six people.
I usually bake it in a 15 cm mould (or a similar springform pan/tray). Of course, you can double the recipe if you have a larger mold — just be aware that the baking time may need to be adjusted.

Banana Cake With Oats
Equipment
- 1 stick blender or food processor
- 1 cake mould (about 15 cm in diameter)
Ingredients
- 3 ripe bananas
- 3 large eggs
- 2 dl rolled oats about 1 cup
- 1 tsp vanilla sugar or 1 tsp vanilla extract
- 0.5 tsp salt
- 60 g dark chocolate, chopped about ⅓ cup
- Walnuts optional
Instructions
- Preheat the OvenStart by setting your oven to 180°C (fan) and let it fully heat while you prepare the batter.
- Make the BatterAdd all the ingredients — except the chocolate — to a mixing bowl. Use a stick blender to blend everything into a smooth, even batter.
- Add the ChocolateRoughly chop the dark chocolate and fold it gently into the batter.
- Bake the CakePour the batter into a lined or greased baking tin. Bake for about 35 minutes. To check if it’s done, insert a skewer or toothpick into the center — if it comes out clean, your cake is ready.
- Let It CoolRemove the cake from the oven and allow it to cool before serving. This helps the texture set and makes it easier to slice.Not eating it right away? Once fully cooled, transfer the cake to an airtight container. Keep it out of direct sunlight, and store it at room temperature for up to 3 days.
Delicious Variations for Your Banana Cake with Oats
Want to make it your own? Try adding a handful of chopped walnuts or pecans alongside the dark chocolate — it gives the cake a slightly crunchier texture and a nutty twist that complements the bananas perfectly.
Looking for something extra cozy? A touch of cinnamon or cardamom in the batter adds just the right warmth and spice.
And if you’re feeling indulgent, a light cream cheese or vanilla frosting can turn this into a proper dessert — perfect for those moments when you’re not counting calories and simply craving something cozy and sweet.
In short, this recipe is super flexible, so don’t be afraid to experiment. After all, it’s hard to go wrong when you’re working with bananas, oats, and chocolate.
Storage and Serving Tips
This cake keeps well for three days when stored in an airtight container at room temperature, away from direct sunlight. That said, there’s no need to refrigerate it unless you live in a particularly warm climate.
The texture often becomes even softer by the second day, and the banana flavor deepens in the best way.
For an extra comforting treat, try warming up a slice in the microwave for 15 to 20 seconds to soften the cake slightly and remelt the chocolate chunks. Just like that, it becomes even more satisfying.
