This banana cake delivers a beautifully moist and tender crumb, bursting with natural banana sweetness. Made with ripe bananas, vegetable oil, and a hint of cinnamon, it comes together in just 20 minutes of prep.
Bake it plain, with toasted walnuts for crunch, or studded with chocolate chips for indulgence. A versatile treat that's equally at home on a dessert plate or alongside a warm cup of afternoon tea.
The smell of overripe bananas has never bothered me, mostly because it means cake is about to happen. There is something deeply satisfying about turning those speckled, neglected fruits into something golden and comforting. This banana cake is the kind of recipe that forgives your imprecise measurements and rewards your patience with a crumb so soft it practically melts. It has saved countless Tuesday afternoons from feeling ordinary.
One rainy Saturday my niece wandered into the kitchen, spotted the bowl of blackened bananas on the counter, and asked if we could bake something before lunch. We ended up eating half the cake warm from the pan, standing at the counter with forks, barely saying a word.
Ingredients
- 3 ripe bananas, mashed: The darker the peel, the sweeter and more intense the banana flavor becomes in the cake.
- 120 ml vegetable oil or melted butter: Oil keeps the crumb softer for longer, but butter adds a richer depth if you plan to serve it the same day.
- 100 g granulated sugar: The bananas contribute natural sweetness, so you do not need as much added sugar as you might expect.
- 2 large eggs: They bind everything together and give the cake its tender structure.
- 1 tsp vanilla extract: A quiet background note that rounds out the banana flavor beautifully.
- 200 g all purpose flour: Spoon it into your measuring cup rather than scooping to avoid a dense, heavy cake.
- 1 tsp baking soda: This is your primary leavening agent and it reacts with the natural acidity in bananas.
- 1/2 tsp baking powder: Works alongside the baking soda for an even, reliable rise.
- 1/4 tsp salt: Never skip this, because salt makes every sweet flavor taste more like itself.
- 1/2 tsp ground cinnamon, optional: Adds a gentle warmth that makes the cake feel like it belongs on a chilly afternoon.
- 75 g chopped walnuts, pecans, or chocolate chips, optional: Fold them in for crunch or little pockets of melted chocolate throughout.
Instructions
- Prepare your oven and pan:
- Heat the oven to 180 degrees Celsius (350 degrees Fahrenheit) and grease a 23 centimeter cake pan with oil or butter, then dust it lightly with flour so the cake releases cleanly.
- Mash and mix the wet ingredients:
- In a large bowl, mash the bananas until mostly smooth with a few small lumps remaining, then beat in the oil, sugar, eggs, and vanilla until everything looks glossy and well blended.
- Whisk the dry ingredients separately:
- Combine the flour, baking soda, baking powder, salt, and cinnamon in a second bowl, whisking them together so the leavening is evenly distributed throughout the flour.
- Bring it all together gently:
- Gradually fold the dry mixture into the wet using a spatula, stopping as soon as no dry streaks remain, because overmixing will make the cake tough and flat.
- Add your extras if using:
- Stir in chopped nuts or chocolate chips with just a few gentle folds so they spread through the batter without sinking to the bottom during baking.
- Pour and smooth the batter:
- Transfer the batter into your prepared pan and use the back of a spoon to nudge it into the corners and smooth the top so it bakes evenly.
- Bake until golden and set:
- Bake for 35 to 40 minutes, checking near the end with a toothpick inserted into the center that should come out clean or with just a few moist crumbs clinging to it.
- Cool before slicing:
- Let the cake rest in the pan for 10 minutes to firm up, then turn it out onto a wire rack to cool completely before serving or adding any frosting.
A friend once told me this cake reminded her of her grandmothers kitchen, and she sat quietly eating a second slice without offering to share.
A Note on Banana Ripeness
If your bananas are yellow but not yet spotted, you can speed things along by placing them on a baking sheet in a 150 degree Celsius oven for about 15 minutes until the skins blacken. The heat concentrates their sugars and breaks down the starches, mimicking days of natural ripening in under half an hour. Frozen bananas also work beautifully, just thaw them completely and drain off any excess liquid before mashing.
Serving Suggestions Worth Trying
A simple dusting of powdered sugar is often all this cake needs, especially when it is still slightly warm. For something more indulgent, a thin layer of cream cheese frosting spiked with lemon zest turns it into something bordering on celebratory. A handful of raisins or toasted coconut flakes folded into the batter adds texture and a unexpected sweetness that catches people off guard in the best way.
Storage and Make Ahead Advice
This cake improves overnight as the flavors settle and the crumb becomes even more tender. Wrap it tightly in cling film or store it in an airtight container at room temperature for up to three days.
- Refrigerate it if you have added cream cheese frosting, and bring it back to room temperature before serving.
- You can freeze individual slices wrapped in foil for up to two months, which makes for a dangerously convenient afternoon treat.
- Always label your frozen portions with the date so nothing gets lost in the back of the freezer.
Keep a few bananas in your freezer and you will never be more than an hour away from something warm, sweet, and entirely homemade.
Common Questions
- → How ripe should the bananas be for this banana cake?
-
Use bananas that are heavily spotted or fully brown on the outside. The riper the bananas, the sweeter and more flavorful your cake will be. Overripe bananas mash easily and blend seamlessly into the batter.
- → Can I substitute butter for vegetable oil in this banana cake?
-
Yes, melted butter works as a direct substitute for vegetable oil in equal measure. Butter adds a richer, slightly denser texture, while oil keeps the crumb more tender and moist for longer.
- → Why did my banana cake sink in the middle after baking?
-
A sunken center usually means the cake was underbaked or the oven door was opened too early. Bake until a toothpick inserted in the center comes out clean, and resist opening the oven during the first 30 minutes.
- → Can I add chocolate chips and nuts together to the batter?
-
Absolutely. Combining 75 g of chocolate chips and 75 g of chopped walnuts or pecans creates a wonderfully textured cake. Fold them in gently at the end to avoid overmixing the batter.
- → How should I store leftover banana cake?
-
Wrap the cooled cake tightly in plastic wrap or store it in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze individual slices for up to 3 months.
- → Is this banana cake suitable for vegetarians?
-
Yes, this banana cake is entirely vegetarian. It uses eggs and dairy-free vegetable oil as the primary fat. If using butter instead of oil, it remains vegetarian as well.
