Banana Cake is the easiest way to turn those spotty bananas on your counter into a moist, tender, lightly sweet treat, and this one bowl snack cake is the version my girls beg for on a lazy Sunday afternoon. It bakes up soft thanks to a secret scoop of vanilla yogurt and comes together in one bowl with no mixer. If you love a cozy from scratch bake, our lemon blueberry coffee cake is another easy favorite.

No frosting, no fuss, just a quick dusting of powdered sugar and a slice that tastes like banana bread in cake form.

Why This Recipe Works
Click to see the technique science
- One bowl, no mixer. Everything comes together with a whisk and a spatula, so this banana cake is genuinely beginner friendly and the cleanup is minimal.
- Vanilla yogurt keeps it moist. A full cup of vanilla yogurt adds tang and moisture, giving the cake a soft, tender crumb without any butter to cream.
- Ripe bananas do the sweetening. Mashed ripe banana brings natural sweetness and that classic banana flavor, so you need only a third cup of sugar.
- Ready in 30 minutes. With just 10 minutes of prep and about 20 in the oven, this is a from scratch cake you can pull off on a busy weeknight.
- No frosting required. A simple dusting of powdered sugar finishes it beautifully, so it feels special without the extra step of making frosting.

Key Ingredients

- All purpose flour: The structure of the cake, measured and whisked with the leaveners for an even rise.

Variations and Substitutions
This banana cake is a great base, so make it your own.
- Fold in a half cup of chocolate chips, chopped walnuts, or pecans for extra texture.
- Add a teaspoon of cinnamon or a pinch of nutmeg for a warm, spiced banana cake.
- Swap the powdered sugar topping for a swirl of cream cheese frosting to dress it up.
- Use Greek yogurt or plain yogurt in place of vanilla, and add an extra splash of vanilla extract.
How to Make Banana Cake

- Preheat the oven to 375 degrees Fahrenheit and spray a 9 inch round cake pan with baking spray. In a large bowl, whisk together the flour, sugar, baking soda, baking powder, and salt.

- In a separate bowl, whisk together the vanilla yogurt, mashed banana, oil, vanilla, and lightly beaten egg until smooth.

- Add the wet ingredients to the center of the dry ingredients and stir until just combined. There should be no dry patches, but do not overmix.

- Pour the batter into the prepared cake pan and smooth out the top with a spatula.

- Bake for 20 to 22 minutes, or until a toothpick inserted in the center comes out mostly clean with just a few crumbs.

- Let the cake cool in the pan for 10 minutes, then invert onto a wire rack to cool completely. Dust with powdered sugar, slice, and serve.
Recipe Tips & Tricks
- Use very ripe bananas with plenty of brown spots, since they are sweeter and mash more easily for the best banana flavor.
- Do not overmix the batter once the wet and dry ingredients meet, or the cake can turn dense and tough.
- Measure flour by spooning it into the cup and leveling off, so you do not pack in too much and dry out the cake.
- Check early at the 20 minute mark, since ovens vary and an overbaked snack cake loses its moist crumb.
- Cool before dusting with powdered sugar, otherwise it melts into the warm cake instead of staying pretty on top.
- Store covered at room temperature for up to 3 days, or wrap and freeze slices for a quick treat later.
Serving Ideas and Suggestions
This banana cake is wonderful all on its own, still slightly warm with a simple dusting of powdered sugar and a cup of coffee or a cold glass of milk. It is the kind of easy snack cake that disappears off the counter by the afternoon.
For dessert, add a scoop of vanilla ice cream or a dollop of whipped cream, or serve it alongside our homemade pistachio pudding for a fun spread.
It also makes a lovely addition to a brunch or potluck table next to a creamy tiramisu pie and a pot of coffee.

Looks delicious! Especially with the drizzle over the top. Pinned and following!
Gorgeous photos of this lovely snacking cake! I love yogurt and looking for ways to incorporate in it foods is high on my list. And, if it’s replacing a less healthy ingredient, all the better! Pinning…
We make banana bread all the time, but I love the idea of substituting the yogurt for the sour cream that we normally use. Hoping I have bananas in the kitchen so we can make this tonight. #client
