Ingredients for banana cake recipe with vegetable oil
Simple pantry staples that transform into a fudgy, moist cake without butter—just oil and bananas.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 whole | Mashed, no brown spots |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Vegetable Oil 🫒 | 1 cup | Light or canola preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Baking Soda 🧂 | 1 tsp | Freshly opened |
| Ground Cinnamon 🌿 | 1 tsp | Warm, aromatic variety |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tbsp | Pure alcohol-free preferred |
| Hot Water 💧 | ¼ cup | For baking soda activation |
| Chocolate Chips 🍫 | 1 cup | Semi-sweet or dark |
| Walnuts 🌰 | ½ cup | Chopped, optional |
The bananas are non-negotiable here—the riper, the better. Brown spots? Perfect. I always grab the extra ripe ones from the back of the produce bin at Trader Joe's—they're cheaper and sweeter. The vegetable oil is the secret weapon. Light or canola gives the best texture, but any neutral oil works. Skip the coconut oil though—it adds a weird flavor. Flour matters too: King Arthur or Gold Medal are my go-tos for consistent results. The baking soda needs to be fresh—if it's been sitting in your pantry for months, toss it and buy a new box.
No eggs? Applesauce works 1:1 for a vegan version, but texture will be slightly denser. Short on chocolate chips? White chocolate or butterscotch chips add a fun twist. The walnuts are totally optional, but I always include them—they add crunch and richness. Need to swap the cinnamon? Pumpkin pie spice at half the amount gives a similar warmth. And if you're baking in a dry climate, add an extra tablespoon of oil—this cake dries out fast once sliced. Pro tip: measure your flour by spooning it into the cup, then leveling it off. Scooping straight from the bag packs it too tightly.
This cake keeps beautifully—3 days at room temperature in an airtight container, or 1 week in the fridge. For longer storage, slice it and freeze between parchment paper for up to 3 months. The best part? It tastes even better the next day as the flavors meld. I always bake two 8-inch layers for parties—double the recipe and use the same pan twice. The aroma while baking? Worth every minute. And if you've got leftover batter, drop spoonfuls onto a baking sheet for banana cake muffins—trust me, they're a game-changer.

Step-by-step instructions for banana cake with vegetable oil
Here's how to make a moist, fudgy banana cake that stays rich and tender—no butter needed.
Mash the Bananas and Mix Wet Ingredients
Start by mashing the 3 whole ripe bananas in a large mixing bowl until completely smooth. You want no lumps—press them through a fine-mesh sieve if needed. The riper the bananas, the sweeter and more flavorful your cake will be.
Add the 1 cup vegetable oil and 1.5 cups granulated sugar, then whisk until fully combined. The oil keeps the cake moist without butter, while the sugar helps create that classic tender crumb. In a separate small bowl, mix the 2 whole large eggs, 1 tbsp vanilla extract, 0.25 cup hot water, and 1 tsp baking soda. The hot water activates the baking soda for maximum lift.
Combine Dry Ingredients and Fold Gently
In the same large bowl, sift in the 2 cups all-purpose flour, 1 tsp ground cinnamon, and 0.5 tsp salt. Whisk just until combined—don’t overmix, or the cake will turn dense. The cinnamon adds warmth, while the salt balances the sweetness and enhances all the flavors.
Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined. You’ll still see some flour streaks, and that’s perfect. Overmixing develops gluten, which makes the cake tough instead of tender. Fold in the 1 cup chocolate chips and 0.5 cup chopped walnuts (if using) until evenly distributed.
Bake Until Golden and Springy
Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. Pour the batter into the pan and smooth the top. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean and the edges are golden brown. The cake should pull away slightly from the sides of the pan.
I know it’s tempting to open the oven early, but resist! The cake needs time to set properly. If the top browns too quickly, tent it loosely with aluminum foil after the first 20 minutes to prevent over-browning while the center finishes baking.
Cool and Serve for Maximum Moisture
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. This resting time allows the cake to set and prevents it from falling apart when you slice it. The longer it cools, the more the flavors meld together, making each bite even richer.
Slice when fully cooled, and serve with a dusting of powdered sugar or a scoop of vanilla ice cream. The texture should be moist and fudgy, with just the right amount of chewiness from the walnuts and pockets of melted chocolate. Store leftovers in an airtight container for up to 3 days—if they last that long!
Pro Tips For Making Banana Cake Recipe With Vegetable Oil
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana puree makes for a dense, uneven cake. Use a fork first to break them up, then switch to a potato masher or fork in a bowl to press out every last bit of moisture. No food processor needed, but if you’re impatient like me, a quick pulse works too.
- Weigh Your Flour: That "cup of flour" you eyeball? It’s probably wrong. Spoon flour into your measuring cup and level it off with a knife—don’t scoop. Too much flour makes the cake dry; too little makes it sink. Trust the scale if you have one, but at least level it properly.
- Bake Until Springy: The cake will look done before it is. Press the center lightly—if it springs back slowly, it’s ready. If it’s still jiggly after 5 minutes past the recipe’s time, walk away. Overbaking turns banana cake into a sad, dry brick, and nobody wants that.
- Swap Oil for Butter: Yes, I know the recipe says vegetable oil, but if you’re using it for richness, melt ¼ cup unsalted butter and cool it slightly before mixing. The flavor upgrade is worth the extra 2 minutes of waiting. Just don’t skip the cooling step—hot butter will cook the eggs before they’re ready.
Wine and beer pairings for this dish
Sweet Dessert Wines
For this banana cake’s rich, caramelized banana flavor, a Moscato d'Asti or Riesling is my go-to. The light sweetness and floral notes in a chilled Moscato (around 50°F) mirror the cake’s natural sweetness without overpowering it. A slightly off-dry German Riesling from the Mosel region adds a citrusy brightness that cuts through the oil’s richness. I always keep a bottle of Blue Nun on hand—it’s a crowd-pleaser and pairs beautifully with the walnuts. 🍷
Creamy Liqueurs
If you’re serving slices with ice cream or whipped cream, a Baileys Irish Cream or Amaretto is a game-changer. The buttery notes in Baileys complement the cake’s fudgy texture, while the almond flavor in Amaretto adds a sophisticated twist. Pour 1-2 ounces into a small glass and serve alongside the cake for a cozy, dessert-like experience. For a non-alcoholic option, vanilla syrup drizzled over the cake works just as well. 🥛
Coffee Pairings
This cake’s warm spices make it a perfect match for espresso or cold brew. The bitterness in coffee balances the cake’s sweetness, while the cinnamon in the cake enhances the coffee’s depth. Serve with a flat white or a doppio espresso for a sophisticated pairing. If you’re a fan of cappuccino, the frothy milk adds a creamy contrast that’s hard to resist. ☕
Beer Contrasts
For a lighter option, a Belgian witbier like Hoegaarden or Stella Artois adds a crisp, citrusy contrast to the cake’s richness. The effervescence cleanses your palate between bites, making each slice taste even better. If you prefer something bolder, a honey wheat ale with its caramel notes complements the banana flavor beautifully. Avoid heavy lagers—they’ll clash with the cake’s density. 🍺
Seasonal Twists
In summer, swap the wine for a sparkling peach schnapps (like Peachtree) to highlight the cake’s natural sweetness. For fall, a spiced rum like Captain Morgan with a dash of cinnamon adds warmth that mirrors the cake’s baking spices. I love pairing it with a dark chocolate ganache drizzle on top for an extra indulgent touch. 🍂

Frequently asked questions
Why does this banana cake use vegetable oil instead of butter?
Vegetable oil creates a rich, moist texture without adding butter's density. It keeps the cake tender and fudgy while preventing dryness. Plus, it's a budget-friendly option that works perfectly with ripe bananas for that classic flavor.
Can I make this cake without eggs?
Yes! Replace the 2 eggs with ½ cup unsweetened applesauce or ½ cup mashed banana (in addition to the original 3 bananas). The texture will be slightly denser but still delicious. For vegan baking, this swap works beautifully.
How do I know when the cake is fully baked?
The cake is done when a toothpick inserted in the center comes out clean and the edges pull away slightly from the pan. Bake for 35-40 minutes at 350°F, but check at 30 minutes—ovens vary! If the top browns too fast, tent with foil after 20 minutes.
What if my cake turns out too dry?
Overbaking is the most common cause. To fix it, brush warm slices with simple syrup (equal parts sugar and water, heated until dissolved) or serve with whipped cream. For next time, reduce baking time by 2-3 minutes and check at 30 minutes.
Can I make this cake in a different pan size?
Yes! For an 8-inch pan, use the same batter but reduce baking time to 25-30 minutes. For a 9x13-inch pan, spread batter thinly and bake for 30-35 minutes. Always adjust time based on your oven's heat. The key is even baking—never overcrowd the pan.
