Easy One-Bowl Strawberry Banana Cake
This strawberry banana cake is a soft, buttery loaf loaded with fresh berries and ripe bananas. It comes together in one bowl and takes about 15 minutes of hands-on time.
The banana keeps it tender while strawberries melt into jammy pockets. No mixer, no fuss, just a really good cake.
What Makes This Cake So Good
Ripe bananas and fresh strawberries do all the heavy lifting here. The banana adds moisture without needing extra butter or oil, so the crumb stays soft for days.
Every slice is speckled with berries that taste like little pockets of jam. They sink just enough to create a pretty top without stirring extra.
It’s the kind of cake you can mix by hand in under 10 minutes and still feel proud to share. I make it whenever the fruit bowl gets ahead of me.
Ingredients
- 1 1/2 cups (190g) all-purpose flour: spoon and level it for an accurate measure
- 1 tsp baking powder: gives the cake its lift
- 1/2 tsp baking soda: helps with browning
- 1/4 tsp fine sea salt: balances the sweetness
- 1/2 cup (113g) unsalted butter, softened: leave it out for 30 minutes so it creams easily
- 3/4 cup (150g) granulated sugar: the bananas bring some sweetness too
- 2 large eggs: room temperature is best
- 2 medium ripe bananas, mashed (about 1 cup): the spottier the skin, the sweeter the fruit
- 1 tsp vanilla extract: rounds out the fruit flavors
- 1 cup (150g) chopped fresh strawberries: about 6–8 medium berries
- 1 tbsp all-purpose flour, for dusting the strawberries: keeps the berries from sinking
Variations / Substitutions
- Swap the butter: use an equal amount of vegetable oil or melted coconut oil for a slightly denser crumb
- Different berries: chopped blueberries, raspberries, or diced peach work the same way, no other changes needed
- Brown sugar: replace half the granulated sugar with light brown sugar for a deeper, molasses-like note
- Gluten-free: use a 1:1 gluten-free flour blend and add 1/4 tsp xanthan gum if the blend does not already include it
- Dairy-free: use a plant-based butter stick and replace each egg with a flax egg (1 tbsp ground flax + 3 tbsp water, left to gel)
If you enjoy fruit-packed loaves, my banana blueberry bread is another one to keep in your back pocket.
How to Make Strawberry Banana Cake
Step 1: Mix the Wet Batter
Preheat the oven to 350°F (175°C) and lightly grease a 9×5-inch loaf pan with butter or nonstick spray. Mash the 2 bananas in a large bowl with a fork until mostly smooth, then add the softened butter, sugar, eggs, and vanilla. Beat with a whisk for about 1 minute until the mixture is creamy and no streaks of egg remain.
The batter will look slightly lumpy from the banana but should be cohesive and pale. A few tiny banana chunks are fine; they disappear as it bakes.
Step 2: Fold in the Dry Ingredients
Add the 1 1/2 cups flour, baking powder, baking soda, and salt directly into the wet mixture. Use a rubber spatula to fold everything together just until you no longer see dry streaks. This should take no more than 30 seconds.
The batter will be thick and a bit shaggy. Stop as soon as the flour disappears — overmixing here makes a tough cake, so a few faint streaks are better than a perfectly smooth batter.
Step 3: Add the Strawberries
Toss the chopped strawberries with the 1 tbsp flour in a small bowl until they are lightly coated. Gently fold them into the batter with just 4 or 5 strokes, leaving the berries unevenly distributed.
Some strawberries will peek out on top, and that is exactly what you want. They will sink a little as the cake bakes, creating a pretty top without any extra work.
Step 4: Bake until Golden
Scrape the batter into the prepared loaf pan and smooth the top with your spatula. If you have a few extra chopped strawberries, press them lightly onto the surface for a nice finish. Bake on the middle rack for 50–60 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
The kitchen will smell like banana bread with a bright strawberry undertone. Check the loaf around the 45-minute mark and tent it loosely with foil if the top is browning too fast.
Step 5: Cool and Slice the Cake
Let the cake cool in the pan on a wire rack for 10 minutes. Run a knife around the edges, then gently turn it out onto the rack to cool completely before slicing, about 1 hour.
Slice with a serrated knife so you do not tear the jammy berries. Every cut reveals a soft, golden crumb dotted with deep red streaks.
Tips for a Perfect Loaf Cake
- If your bananas are only yellow and green, speed-ripen them by baking them unpeeled at 300°F for 15–20 minutes until the skins turn black. Let them cool, then mash.
- For the cleanest slices, cool the loaf completely and then pop it in the fridge for 20 minutes. The cake firms up just enough to cut neatly without squishing the fruit.
- An 8×4-inch pan makes a thicker loaf and needs an extra 10–15 minutes in the oven; start checking at 60 minutes.
- This cake is even better the next day. Wrap it tightly overnight and the flavors mellow together into an even softer crumb.
Bake times by pan size:
| Pan Size | Estimated Bake Time |
|---|---|
| 9×5-inch | 50–60 minutes |
| 8×4-inch | 60–75 minutes |
Storing Leftover Cake
- Refrigerate: Keep the cake tightly wrapped at room temperature for up to 3 days. In warm weather, refrigerate it for up to a week; bring it back to room temperature before serving for the best texture.
- Reheating: A 10-second zap in the microwave revives a slice, softening the butter and making the strawberries even jammier.
What Goes Well With Strawberry Banana Cake
This cake is perfect with a cup of black coffee or a pot of Earl Grey tea; the slight bitterness cuts through the sweetness. For an afternoon snack, spread a slice with salted butter and let it melt into the warm crumb. A scoop of vanilla ice cream and a spoonful of the juicy berries from the pan makes an easy dessert.
Frequently Asked Questions
Can I freeze this cake?
Yes, wrap the completely cooled loaf tightly in plastic wrap, then a layer of foil, and freeze for up to 3 months. Thaw at room temperature before slicing.
Can I make these as muffins instead?
Absolutely. Divide the batter evenly into 12 lined muffin cups and bake at 350°F for 20–22 minutes, or until a toothpick comes out clean.
What if I don’t have a loaf pan?
A 9-inch round cake pan works nicely. The bake time will be shorter, around 30–35 minutes; check with a toothpick and pull it when only a few crumbs stick.
