Ingredients for banana cake recipe with oil and baking powder
Just 12 ingredients create this light-as-air banana cake with crisp edges—no butter needed!
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Mashed thoroughly for smooth batter |
| All-Purpose Flour 🌾 | 2 ½ 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 mixing |
| Baking Powder 🍞 | 2 tsp | Double-acting for crispness |
| Baking Soda 🧂 | ½ tsp | Freshly measured |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground for warmth |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
| Warm Water 💧 | ¼ cup | For baking soda activation |
| Powdered Sugar 🍚 | ½ cup | For dusting top |
The bananas are everything here—overripe with brown spots gives the deepest flavor. I always grab 3-4 extra from the grocery store's discount bin (they're cheaper and sweeter!). For the flour, King Arthur or Gold Medal brands work best—they're sifted for you, saving time. The vegetable oil keeps this cake moist for days, unlike butter cakes that dry out. Pro tip: measure your oil by weight (about 8 oz) for consistency if you're feeling fancy.
No vanilla extract? 1 tsp vanilla sugar (like McCormick) works in a pinch. Short on baking powder? Mix 1 tsp cream of tartar + 1 tsp cornstarch as a substitute. The cinnamon can be swapped for 1/2 tsp pumpkin pie spice if that's what you've got. For the water, room temperature is key—cold water slows the baking soda reaction. And yes, you can use melted coconut oil if you're making this vegan, but the flavor shifts slightly.
This cake stays fresh for 5 days covered at room temp, or 1 week in the fridge. For longer storage, freeze slices wrapped in parchment—they thaw in 10 minutes. The powdered sugar topping? Only sprinkle it after baking—it burns if added to raw batter. I always make a double batch because this disappears faster than you can say 'second slice.'
Why You'll Love This Recipe
- No Overmixing Needed: I swear by this recipe because the oil and baking powder combo keeps things light—no tough, dense cake here. Mash those bananas, toss in the dry ingredients, stir until just combined, and you’re done. No stand mixer, no stress.
- Sweet Without Syrup: That natural banana sweetness cuts the sugar load, but don’t worry—it’s still rich and satisfying. The oil keeps it moist for days, so you won’t miss a drop of butter or syrup. Honestly, my kids ask for seconds before the plate’s even empty.
- Breakfast or Dessert: Serve it warm with a drizzle of honey for a lazy Sunday morning, or pack slices for lunch—it’s that versatile. Even my picky husband grabs a piece after dinner. (Yes, even on a Tuesday night.)

Step-by-step instructions for banana cake with oil and baking powder
This method delivers a tender, moist cake with perfect crispness—no butter needed!
👨🍳 Step 1: Mash the Bananas and Mix Wet Ingredients
Start by mashing the 3 medium ripe bananas in a large mixing bowl until completely smooth—no lumps! I like to use a fork first, then press through a fine-mesh sieve if needed for extra smoothness. This ensures a tender crumb later.
Add the 1 cup vegetable oil and 1.5 cups granulated sugar, then whisk until fully combined. The mixture should look like a thick, creamy paste. Next, beat in the 2 whole large eggs one at a time, mixing well after each addition. Stir in the 1 tsp vanilla extract and set aside.
👨🍳 Step 2: Combine Dry Ingredients and Create the Batter
In a separate bowl, sift together the 2.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp baking soda, 0.5 tsp salt, and 1.5 tsp ground cinnamon. This step is crucial for a light, airy texture—don't skip sifting!
Gradually add the dry ingredients to the wet mixture, mixing on low speed with an electric mixer or by hand until just combined. Be careful not to overmix—stop as soon as the flour disappears. In a small cup, mix the 0.25 cup warm water with the remaining 0.5 tsp baking soda, then stir this into the batter. The batter should be thick but pourable.
🔥 Step 3: Bake to Golden Perfection
Preheat your oven to 350°F and grease two 9-inch round cake pans or one 9x13-inch baking pan. Pour the batter evenly into the prepared pan(s). For even baking, tap the pan gently on the counter to release any air bubbles.
Bake for 30-35 minutes (or 40-45 minutes for the 9x13-inch pan) until a toothpick inserted in the center comes out clean and the edges are golden brown. The top should spring back when gently touched. Real talk: your oven might run hot, so start checking at the 25-minute mark for 9-inch pans.
⏰ Step 4: Cool and Dust with Powdered Sugar
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely. This resting period prevents the cake from sinking in the center as it cools.
Once fully cooled, dust the top generously with 0.5 cup powdered sugar using a fine-mesh sieve. This adds that classic banana cake finish and balances the warm cinnamon notes. Slice and serve warm for the best texture—each bite will be moist, tender, and perfectly sweet!
Pro Tips For Making Banana Cake Recipe With Oil And Baking Powder
- Mash Bananas Thoroughly: Don’t just smash them with a fork—use a potato masher or fork in a bowl to break up every last speck of banana, including the skins. I learned this the hard way when my cake turned out dense because I missed those stubborn bits clinging to the sides.
- Use Room-Temperature Eggs: Crack those eggs straight from the fridge, but let them sit in a bowl for 10 minutes before mixing. Cold eggs make the batter thicker and can cause uneven baking—your cake will rise better and have a lighter texture if you skip this step.
- Grease the Pan Well: This isn’t just about preventing sticking—it’s about keeping the cake from tearing when you pull it out. Use a paper towel to wipe down the pan with oil after greasing, especially if you’re using a nonstick one. (Yes, even if it looks clean.)
- Check Doneness with a Toothpick: The cake’s done when the toothpick comes out with a few moist crumbs, not wet batter. Overbaking dries it out, and underbaking leaves it gummy—both ruin the texture. If yours tests clean too early, tent it with foil and give it 5 more minutes.
Perfect pairings for this recipe
Creamy Ice Cream
This banana cake pairs beautifully with homemade vanilla bean ice cream—the cool creaminess contrasts perfectly with the warm, spiced cake. I always make a batch of Blue Bell Homemade Vanilla or Ben & Jerry's Phish Food (yes, I'm a little biased) for that nostalgic flavor. The vanilla notes in the ice cream complement the cake's cinnamon warmth without overpowering it. Serve a slice warm with a scoop for the ultimate dessert experience. 🍦
Spiced Coffee
A cup of spiced coffee elevates this cake to restaurant-level quality. Try a cinnamon-dusted chai latte or a dark roast with a pinch of cardamom—both enhance the cake's warm spices. I love brewing Death Wish Coffee with a splash of vanilla syrup and a dash of cinnamon for extra coziness. The caffeine helps cut through the cake's richness while highlighting its natural sweetness. ☕
Fresh Berries
For a lighter pairing, top your cake slice with fresh strawberries or raspberries—their tartness balances the cake's sweetness beautifully. I always buy local Texas strawberries from Central Market when they're in season, or organic raspberries from Austin farmers markets. A drizzle of honey adds extra depth. This combo works especially well for brunch or afternoon tea. 🍓
Whipped Cream
No dessert is complete without homemade whipped cream! Whip 1 cup heavy whipping cream with 1 tablespoon powdered sugar and ½ teaspoon vanilla extract until soft peaks form. The light, airy texture contrasts perfectly with the cake's dense crumb. I sometimes add a pinch of ground cinnamon to the whipped cream for an extra flavor boost that ties back to the cake. 🥛
Chocolate Ganache
For chocolate lovers, a dark chocolate ganache drizzle adds luxurious depth. Melt ½ cup dark chocolate chips with ¼ cup heavy cream and let it cool slightly before drizzling over cake slices. The bitterness of the chocolate contrasts wonderfully with the cake's sweetness. I use Ghirardelli 70% dark chocolate for the best balance of richness and flavor. 🍫
Citrus Zest
Brighten up your banana cake with a sprinkle of lemon or orange zest—just ½ teaspoon adds a refreshing citrus note that cuts through the sweetness. I often zest organic Meyer lemons from my Austin garden or navel oranges from Central Market. The zest pairs especially well with the whipped cream option for a springtime dessert. 🍋

Frequently asked questions
Why does this recipe use oil instead of butter?
Oil creates a moist, tender crumb that stays fresh longer than butter-based cakes. The vegetable oil also helps develop that signature crisp exterior while keeping the interior soft. Plus, it's easier to measure and mix—no risk of over-creaming like with butter!
Can I substitute baking powder with baking soda?
No, they're not interchangeable! This recipe needs both baking powder (2 tsp) and baking soda (0.5 tsp) for proper rise and texture. If you must substitute, use 1.5 tsp baking powder and add 1 tsp cream of tartar to the dry ingredients for similar leavening power. Never use baking soda alone—it'll make your cake dense and bitter.
How do I know when my cake is fully baked?
Use the toothpick test: insert it in the center—it should come out clean with just a few moist crumbs. The edges should be golden brown, and the top should spring back when gently touched. For 9-inch pans, start checking at 25 minutes since ovens vary. Underbaking is worse than overbaking!
What's the best way to store banana cake?
Keep it covered at room temperature for 3-4 days in an airtight container. For longer storage, slice and freeze portions wrapped in plastic for up to 3 months. Reheat individual slices in the microwave for 10-15 seconds to restore freshness. The powdered sugar topping should be added fresh before serving.
Can I make this cake gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add ½ tsp xanthan gum to the dry ingredients for proper structure. You may need to reduce the warm water by 1 tablespoon since GF flours absorb differently. Expect a slightly denser texture but still delicious!
