This banana olive oil cake delivers moist, tender layers without a drop of butter—thanks to the secret power of heart-healthy olive oil. 💛 After years of perfecting the balance between richness and lightness, I’ve created a recipe that’s both indulgent and nutritious, with a texture so perfect it disappears on the first bite.
The olive oil does more than replace butter—it creates a velvety crumb that stays moist for days, while the ripe bananas add natural sweetness and a subtle caramelized depth when baked. This cake is foolproof for beginners but impressive enough for gatherings, requiring just 30 minutes of prep and 35-40 minutes in the oven at 350°F.

The olive oil is non-negotiable here. Look for extra-virgin—the fruity, peppery kind, not the bland refined stuff. Trader Joe's and Whole Foods carry great options, or check the international aisle at regular grocery stores. Ripe bananas are key: they should be soft enough to mash with a fork, but not mushy. Two medium bananas (about 1 cup mashed) give you that perfect sweetness without overpowering. If you're worried about texture, let them sit at room temperature for 30 minutes before mashing.
No vanilla extract? Vanilla bean paste works just as well, or even a scraped vanilla bean. Short on Greek yogurt? Plain whole-milk yogurt is fine, but it won't be as thick. The walnuts can be swapped for pecans or almonds—whatever you've got on hand. For a chocolate twist, fold in 1/2 cup chocolate chips with the dry ingredients. And if you're feeling fancy, add a swirl of lemon curd before baking. The powdered sugar and honey are totally optional, but they take this cake from 'good' to 'wow' in seconds.
This cake keeps beautifully—4-5 days in an airtight container at room temperature, or up to 1 week in the fridge. For longer storage, wrap tightly and freeze for up to 3 months. I always bake an extra layer and freeze it—perfect for last-minute gatherings. To reheat, pop a slice in the microwave for 10 seconds. The texture stays moist either way, but it's especially magical fresh out of the oven.
Why You'll Love This Recipe
- No Mash Needed: The ripe bananas mash themselves—just smash them with a fork. No blender, no strainer, no fuss. Between us, I’ve burned out blenders for less.
- Olive Oil Magic: That rich olive oil keeps it moist for days. It’s not just cake—it’s got this subtle, buttery depth that makes every slice taste like a hug from your nonna.
- Breakfast or Snack: Serve it warm with yogurt for breakfast or cut into squares for a grab-and-go treat. Honestly, I’ve eaten it straight from the pan at midnight and still begged for more.
- Fridge Hero: Leftovers? They’re not just edible—they’re better. The olive oil keeps it tender, so even day-old slices stay soft. And since it’s cheap to make, you’ll bake it twice before realizing you’re out.
Step-by-step instructions for banana olive oil cake
Here's how to bake a tender, moist cake using olive oil's natural richness.
👨🍳 Step 1: Prep Ingredients and Preheat Oven
Start by preheating your oven to 350°F. While it heats, measure out all your dry ingredients: the 2 cups all-purpose flour, 1 cup granulated sugar, 1 tablespoon baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Sift them together in a medium bowl to remove any lumps and create even texture—this prevents dense spots in your cake.
In a separate bowl, mash the 2 medium ripe bananas until completely smooth. I like to press them through a fine-mesh sieve to remove any skins or fibrous bits that could make the cake gummy. Add the 0.75 cup extra-virgin olive oil, 2 whole large eggs, 0.5 cup plain Greek yogurt, 1 teaspoon vanilla extract, and mix until fully combined. The olive oil will give your cake that signature moistness without needing extra butter.
🍳 Step 2: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, folding gently with a spatula until just combined. You'll want to stop mixing as soon as you see no more flour streaks—overmixing develops gluten and makes the cake tough. The batter should be thick but pourable, like heavy pudding. If it seems too stiff, add 1-2 tablespoons milk (though our ingredients list doesn't include it, this is a common troubleshooting step).
Here's a pro tip: Don't skip the yogurt. It adds moisture and protein that helps create that perfect tender crumb. The olive oil and yogurt combo is what makes this cake so uniquely moist compared to traditional butter cakes. Stir in the 0.25 cup toasted walnuts if using, reserving a few for topping later.
🥘 Step 3: Bake Until Golden and Springy
Grease two 8-inch round cake pans (or one 9x13-inch pan) and line the bottoms with parchment paper. Divide the batter evenly between the pans. Bake for 25-30 minutes (or 30-35 minutes for the sheet pan) until a toothpick inserted in the center comes out clean and the edges are golden brown. The top should spring back when gently pressed—this is your perfect doneness test.
I always check for doneness at the 25-minute mark because ovens vary. If the top browns too quickly, tent the pans with foil to prevent overbrowning while the center finishes cooking. The olive oil helps create a beautiful even color without needing extra browning.
⏰ Step 4: Cool and Finish with Honey Glaze
Remove the cakes from the oven and let them cool in their pans for 10 minutes. Then transfer to a wire rack to cool completely. While they're still warm, brush the tops with 2 tablespoons honey diluted with 1 teaspoon warm water. This creates a beautiful glossy finish and adds subtle sweetness that complements the banana flavor perfectly.
Once completely cooled, dust the tops with 0.25 cup powdered sugar through a fine-mesh sieve for a professional finish. The contrast between the moist cake and light dusting of powdered sugar makes this cake look absolutely stunning. Serve slices at room temperature for the best texture—each bite will be tender with just the right amount of natural sweetness from the bananas.
Pro Tips For Making Banana Cake Recipe With Olive Oil
- MEASURE OIL COLD: The recipe likely calls for olive oil at room temperature—skip the microwave. Cold oil blends smoother into the batter, preventing greasy pockets that make the cake dense. I used to eyeball it warm, and the texture always suffered.
- MASH BANANAS UNTIL SILKY: No lumps. Use a fork first, then press through a fine-mesh sieve or press against the bowl’s side to strain out excess liquid. This keeps the cake tender, not soggy—trust me, I’ve drowned cakes with overripe bananas before.
- DON’T OVERMIX THE BATTER: Stop when the flour just disappears. Olive oil is liquid gold here, but overworking it turns the cake tough. Fold in dry ingredients until barely combined—think "marbled," not "homogeneous."
- BAKE UNTIL TOOTHPICK COMES OUT CLEAN: Olive oil makes this cake rich, so it’s easy to underbake. Check at 325°F (165°C) for 5 minutes early—if it springs back slowly, it’s done. A damp toothpick? Add 5–10 more minutes. I learned this after cutting into a gummy mess.
Wine and beer pairings for these flavors
Sweet Wine Pairings
For this banana olive oil cake, I reach for Moscato d'Asti—a lightly sparkling Italian wine with honeyed apple and peach notes that mirror the cake's natural sweetness. Its low alcohol content (5-6%) makes it perfect for dessert without overwhelming the delicate banana flavor. Serve chilled to enhance its effervescence and let the fruity aromas complement the cake's moist texture. 🍷
Rich Dessert Reds
If you prefer red wine, a Pinot Noir with bright cherry and vanilla undertones works beautifully. Look for one from Oregon or Burgundy—these regions produce wines with enough fruitiness to stand up to the cake's richness while avoiding heavy tannins. The 2019 Domaine Serene Pinot Noir from Oregon is my go-to for its smooth finish and subtle earthiness. 🍇
Creamy Beer Options
A Belgian-style witbier like Hoegaarden adds a refreshing contrast with its citrusy coriander notes and slight tartness. The effervescence cuts through the cake's density, while the honeyed malt enhances the banana's natural sweetness. For a bolder option, try a Belgian dubbel like Westmalle Dubbel—its caramel and raisin flavors create a stunning dessert pairing. 🍺
Coffee Liqueur Twist
For a post-dinner treat, serve slices with a drizzle of Kahlúa (coffee liqueur) and a sprinkle of dark chocolate shavings. The bitter-sweet balance elevates the cake's caramelized banana notes, while the coffee adds depth. This combo feels like a grown-up dessert without sacrificing the cake's natural simplicity. ☕
Seasonal Adaptations
In summer, swap the wine for sparkling rosé—its strawberry and citrus flavors refresh the palate. For fall, a Port-style ruby port with its dried fruit and spice notes pairs wonderfully with the cake's warm, toasted walnut topping. The 1970 Taylor Fladgate is a classic choice for special occasions. 🍂
Nutrition facts
Frequently asked questions
Why use olive oil instead of butter in banana cake?
The olive oil creates a moist, velvety texture without adding dairy, making this cake naturally lighter. It also enhances the banana's caramel notes while providing heart-healthy fats. Plus, it prevents the cake from drying out as quickly as butter-based versions!
Can I make this cake without Greek yogurt?
Yes! Substitute with 0.5 cup sour cream or 0.5 cup applesauce for moisture. The yogurt adds protein and tenderness, but these alternatives work in a pinch. Just reduce other liquids slightly if your batter seems too runny.
How do I know when the cake is fully baked?
Insert a toothpick into the center—it should come out with a few moist crumbs, not wet batter. The edges should also pull away slightly from the pan. If unsure, check at 25 minutes (for 8-inch pans) and tent with foil if browning too fast.
What if my cake is too dense?
Overmixing or underbaking usually causes density. Next time, fold dry ingredients gently until just combined, and bake until a toothpick comes out clean. For extra fluffiness, add 1 teaspoon baking powder or 1/4 teaspoon nutmeg to the dry mix.
Can I add chocolate to this recipe?
Fold in 1/2 cup chocolate chips with the dry ingredients or create a swirl with melted dark chocolate before baking. For a decadent twist, top with a honey-chocolate drizzle after cooling. The olive oil keeps the chocolate from overpowering the banana flavor.
