Ingredients for banana bundt cake recipe with oil
Golden crunch meets silky swirls—this oil-based banana cake uses pantry staples for restaurant-quality results.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Mashed, about 1.5 cups |
| Vegetable Oil 🫒 | 1 cup | Light or canola preferred |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for best texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Brown Sugar 🍚 | ½ cup | Packed for moisture |
| Baking Powder 🧂 | 2 tsp | Fresh for best rise |
| Baking Soda 🧂 | 1 tsp | Ensures proper lift |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla preferred |
| Eggs 🥚 | 2 large | Room temperature |
| Sour Cream 🍶 | ½ cup | Full-fat for moisture |
| Walnuts 🥜 | ½ cup | Toasted, chopped optional |
| Powdered Sugar 🍚 | ½ cup | For dusting, optional |
The bananas are everything here—ripe with brown spots is key for that deep, caramelized flavor. Grab 3 medium bananas from the produce section, not the pre-sliced kind (they’re usually less ripe). For the oil, light or canola works best—it’s neutral and keeps the cake moist without adding butter’s richness. If you’re at Trader Joe’s, their organic canola oil is a great pick. The flour? King Arthur or Gold Medal are my go-tos—they bake up light and fluffy. Sift it first for that perfect texture, trust me on this.
No sour cream? Greek yogurt works in a pinch—just use the same amount. Short on walnuts? Pecans or chopped almonds add a nice crunch too. The vanilla extract matters—pure, not imitation—so if you’re splurging, grab a small bottle from Williams Sonoma. Their Madagascar Bourbon is worth it. For the sugars, white granulated gives that classic cake flavor, while light brown adds subtle depth. Don’t skip the baking powder and soda—they’re the secret to that golden crunch on the outside and tender swirls inside. If you’re worried about overmixing, this recipe is forgiving, but mix just until combined.
This cake keeps beautifully—3 days at room temperature wrapped tightly, or 5 days in the fridge for maximum freshness. For longer storage, freeze slices wrapped in plastic for up to 3 months. The walnuts stay crisp if toasted fresh, but you can add them right before serving if you’re prepping ahead. Pro tip: Brush the warm cake with a little simple syrup (equal parts sugar and water, heated) for extra moisture. Pairs perfectly with vanilla ice cream or a drizzle of caramel sauce—because why not?

Step-by-step instructions for banana Bundt cake with oil
Here's how to bake a moist, flavorful Bundt cake with that perfect golden crunch and swirled banana goodness inside.
👨🍳 Step 1: Prep the Bananas and Mix Wet Ingredients
Start by mashing the 3 medium ripe bananas until completely smooth—no lumps allowed. The riper the bananas, the sweeter and more flavorful your cake will be. In a large mixing bowl, combine the mashed bananas with the 1 cup vegetable oil, 2 cups granulated sugar, 0.5 cup packed brown sugar, and 2 tsp vanilla extract. Mix until fully incorporated, creating a thick, creamy batter base.
Here's the thing—don't skip the oil. It keeps this cake incredibly moist, even days later. I like to let this mixture sit for 5 minutes while I prepare the dry ingredients. This gives the flavors time to meld and makes the next step easier.
👨🍳 Step 2: Combine Dry Ingredients and Sour Cream
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 1 tsp baking soda, and 0.5 tsp salt. Sifting the flour first ensures no lumps in your final batter. Gently fold these dry ingredients into your wet mixture in three additions, mixing just until combined after each addition. Overmixing develops gluten, which can make your cake tough.
Now stir in the 2 large eggs and 0.5 cup sour cream. The sour cream adds that signature moistness and tender crumb. I use a spatula for this part to avoid overworking the batter. You're looking for a thick, smooth consistency—like a thick pancake batter. If it looks too stiff, don't panic; the bananas will help it come together.
🥘 Step 3: Fold in Walnuts and Prepare the Bundt Pan
Gently fold in the 0.5 cup walnuts (toasted if you prefer extra flavor). These add a delightful crunch that contrasts beautifully with the soft cake. While your batter rests for 10 minutes, preheat your oven to 350°F and generously grease your 10-cup Bundt pan with vegetable oil or baking spray. I use a mix of oil and flour for extra insurance against sticking.
Here's where it gets fun—after the 10-minute rest, pour the batter into the prepared Bundt pan. Tap the pan gently on the counter a few times to release any air bubbles. This ensures your cake rises evenly and has that perfect domed top. Don't overfill—the batter should reach about halfway up the pan's sides.
🔥 Step 4: Bake to Golden Perfection
Bake for 50-55 minutes until a toothpick inserted in the center comes out clean with just a few moist crumbs. The cake should be golden brown at the edges, with a slight pull from the pan when you gently tug. I know it's tempting to open the oven early, but resist! The first 40 minutes are critical for even baking.
If your oven runs hot, start checking at the 45-minute mark. The cake is done when it springs back when touched lightly and passes the toothpick test. Let it cool in the pan for 15 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking and helps maintain that perfect Bundt shape.
🍽️ Step 5: Dust and Serve with Confidence
Once completely cool, dust the top with 0.5 cup powdered sugar for that classic Bundt cake presentation. The contrast between the golden cake and white sugar is pure visual appeal. Slice into wedges and serve warm or at room temperature. Each bite should deliver that perfect balance of moist cake, sweet banana flavor, and subtle walnut crunch.
Pro tip: For extra drama, serve with a scoop of vanilla ice cream or a dollop of whipped cream. This cake keeps well for up to 3 days at room temperature or 3 months in the freezer—making it perfect for meal prep or special occasions. Enjoy every delicious bite!
Pro Tips For Making Banana Bundt Cake Recipe With Oil
- Mash Bananas Like You Mean It: I learned this the hard way—lumpy banana puree makes for a dense, uneven cake. Use a fork first to break them up, then press through a fine-mesh strainer or blend briefly with 1-2 tablespoons of the oil to get a smooth, thick batter. No strainer? Rub the mashed bananas through a wire whisk until silky.
- Preheat the Oven to 350°F—Then Wait: I used to rush this and end up with a cake that baked unevenly, especially in the center. Let the oven preheat for 15-20 minutes before greasing the Bundt pan. A hot pan ensures even heat distribution from the start—no more dry edges or a gummy middle.
- Skip the Overmixing: After burning three batches, I finally figured out that overmixing develops the gluten in the flour, turning your tender banana cake into a tough, chewy mess. Stir the dry ingredients into the wet just until combined—lumps are fine, but don’t drag that whisk around like you’re frosting a wedding cake.
- Grease the Pan Right: This isn’t the prettiest method, but it’s the tastiest: brush the Bundt pan with melted shortening (not oil) after greasing with vegetable oil, then dust with flour. The extra fat layer keeps the cake from sticking, especially in the tight tubes. (Yes, even if you’re impatient like me—trust the process.)
Wine and beer pairings for this dish
Sweet Wine Pairings
This banana bundt cake’s rich, caramelized banana flavor and moist texture pairs beautifully with sweet dessert wines. I love Moscato d’Asti—its light effervescence and honeyed notes complement the cake’s natural sweetness without overpowering it. For something more robust, try a late-harvest Riesling from Washington State, like Chateau Ste. Michelle. The wine’s crisp acidity balances the cake’s richness while enhancing its banana flavor. 🍷
Creamy Beer Complements
Believe it or not, cream ales work surprisingly well with banana bundt cake. A Guinness or Heineken adds a malty contrast that cuts through the sweetness, creating a perfect balance. For a lighter option, try a Belgian-style witbier like Hoegaarden—its citrusy notes and subtle spice pair wonderfully with the cake’s vanilla and walnut flavors. Serve both at room temperature for the best experience.
Coffee Liqueur Twist
If you’re serving this cake with a boozy touch, a splash of Kahlúa in your coffee or a Baileys drizzle takes it to the next level. The coffee liqueur’s deep, toasty notes enhance the banana’s caramelized sweetness, while Baileys adds a velvety creaminess that mirrors the cake’s texture. For a non-alcoholic option, vanilla syrup or caramel sauce works just as well. 💛
Spiced Rum Enhancement
For a tropical twist, serve slices with a side of spiced rum like Captain Morgan. The warm cinnamon and nutmeg notes in the rum echo the cake’s subtle spices, while the rum’s depth adds complexity. Drizzle a little over the top or serve it warm in a mug for a cozy dessert experience. This pairing works especially well during colder months when you crave something comforting.
Tea Pairings for Lighter Enjoyment
If you prefer tea, Earl Grey or Chai are fantastic choices. The bergamot in Earl Grey adds a bright, citrusy contrast to the cake’s sweetness, while Chai’s warm spices—cardamom, cinnamon, and cloves—complement the walnuts and vanilla beautifully. Brew a strong cup and serve it alongside slices for a sophisticated, caffeine-friendly pairing. ✨

Frequently asked questions
Why use oil instead of butter in banana bundt cake?
Oil creates a moist, tender crumb that stays fresh longer than butter-based cakes. It also prevents dryness, especially since bananas already add natural moisture. Plus, oil blends smoothly without risking lumps or graininess in the batter.
Can I substitute sour cream with something else?
Yes! Use Greek yogurt (same amount) or buttermilk for moisture. For a dairy-free option, try unsweetened applesauce (reduce by 2 tablespoons). The key is maintaining the cake's tender texture—these swaps work in a pinch.
What if my cake sticks to the Bundt pan?
Grease the pan thoroughly with vegetable oil and dust with flour before pouring batter. For extra insurance, use baking spray (like Pam) after greasing. Tap the pan gently on the counter before baking to release air bubbles, which helps prevent sticking.
How do I make this cake gluten-free?
Replace the 2.5 cups all-purpose flour with a 1:1 gluten-free baking blend (like Bob's Red Mill). Add 1 tsp xanthan gum to improve texture. For best results, let the batter rest 15 minutes before baking to hydrate the blend properly.
Can I bake this in a regular round pan?
Use a 9-inch round or tube pan and reduce baking time by 5-10 minutes. The cake will still be delicious, though the Bundt shape creates those stunning swirls. For even baking, rotate the pan halfway through the cooking time.
