Ingredients for banana cake recipe with chocolate frosting
Bananas, flour, chocolate—just 14 ingredients for this crowd-pleasing dessert masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Overripe with brown spots preferred |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Vegetable Oil 🫒 | ½ cup | Light or canola preferred |
| Eggs 🥚 | 2 large | Room temperature for blending |
| Baking Soda 🧪 | ½ tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla extract |
| Dark Chocolate Chips 🍫 | ½ cup | Semi-sweet or bittersweet |
| Unsalted Butter 🧈 | ½ cup | Cold for ganache |
| Heavy Cream 🥛 | ½ cup | Cold for ganache |
| Semisweet Chocolate Chips 🍫 | ¾ cup | For ganache |
| Powdered Sugar 🍚 | 1 cup | For dusting |
| Walnuts 🌰 | ¼ cup | Chopped, optional topping |
Those brown-spotted bananas are your secret weapon. Trader Joe's or your local produce section usually has them—look for the squishiest ones. The chocolate chips? Ghirardelli or Enjoy Life brands melt beautifully. Walnuts are optional but add a lovely crunch—Costco sells them in bulk for great prices. For the butter and cream, grab Land O'Lakes or Organic Valley if you want rich flavor. Don't skip the vanilla extract—Nielsen-Massey is the gold standard, but any pure extract will work.
No ripe bananas? Overripe frozen bananas work perfectly—thaw and drain excess liquid. Swap vegetable oil for melted coconut oil if you prefer. For the ganache, dark chocolate bars (70% cocoa) make it extra decadent. The powdered sugar can be swapped for confectioners' sugar—just make sure it's lump-free. Want more chocolate flavor? Add 1 tbsp cocoa powder to the cake batter. The walnuts can be omitted if you're nut-free, but the cake will still be delicious.
Bananas keep for 3-4 days in the fridge once ripe. The cake batter can be prepped ahead and refrigerated for 24 hours—just bake straight from the fridge. Ganache sets in 30 minutes at room temperature, but it's best made fresh. Store leftovers in the fridge for 5 days—reheat slices in the microwave for 10-15 seconds to revive the chocolate. Freeze portions for up to 3 months—they thaw beautifully.

Step-by-step instructions for banana cake with chocolate frosting
Here's how to bake a perfectly moist banana cake with rich chocolate ganache—no dry crumbs in sight.
👨🍳 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 allowed. This ensures your cake stays moist and tender. Stir in the 0.5 cup vegetable oil and 1 cup granulated sugar until fully combined. The mixture should look like a thick, creamy batter.
Add the 2 large eggs one at a time, whisking vigorously after each addition until the mixture is pale and fluffy. This step incorporates air, which helps create that light, airy texture. Stir in the 1 tsp vanilla extract and set the bowl aside. Here's the thing—overripe bananas with brown spots are key for that deep banana flavor and extra moisture.
👨🍳 Step 2: Combine Dry Ingredients and Fold In
In a separate bowl, whisk together the 1.5 cups all-purpose flour, 0.5 tsp baking soda, and 0.5 tsp salt. Sift the flour first for a lighter texture—this prevents dense cake. Gently fold the dry ingredients into the wet mixture just until combined. You'll see some flour streaks, and that's perfect—overmixing develops gluten, which can make the cake tough.
Fold in the 0.5 cup dark chocolate chips by hand using a rubber spatula. Make sure they're evenly distributed throughout the batter. The chocolate chips will melt slightly during baking, creating pockets of rich flavor in every bite. Don't skip this step—it's what makes this cake special.
🔥 Step 3: 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 prepared pan and smooth the top with a spatula. Bake for 40-45 minutes until a toothpick inserted in the center comes out clean and the edges are golden brown.
I know it seems like too much time, but trust me—the cake needs that full bake to develop proper structure while staying moist. If you pull it out too early, it'll be underdone and dense. The cake should spring back slightly when pressed in the center, not leave an indentation.
🥘 Step 4: Make the Chocolate Ganache
While the cake bakes, make the ganache by combining the 0.5 cup unsalted butter and 0.5 cup heavy cream in a small saucepan. Heat over medium-low heat until the butter melts completely. Remove from heat and stir in the 0.75 cup semisweet chocolate chips until fully melted and smooth.
Let the ganache cool slightly until it's thick enough to spread but still pourable—about 10 minutes. The mixture should coat the back of a spoon but still flow easily. If it thickens too much, whisk in a teaspoon of hot water to loosen it. This ganache is what transforms a good cake into an amazing one.
🍽️ Step 5: Assemble and Decorate
Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. Once cooled, spread the ganache evenly over the top of the cake, letting it drip slightly over the edges for that professional look. Sprinkle the 0.25 cup chopped walnuts over the ganache if using, pressing them gently into the top.
For extra decadence, dust the sides with the 1 cup powdered sugar using a fine-mesh sieve. Serve slices warm or at room temperature—this cake is best enjoyed the day it's made when the ganache is still smooth and the cake is perfectly moist. Each bite delivers that perfect balance of tender banana cake and rich chocolate ganache.
Pro Tips For Making Banana Cake Recipe With Chocolate Frosting
- Mash Bananas First, Then Measure: I used to dump in whole bananas and wonder why the cake turned out dense—turns out, breaking down those fibers early makes a real difference. Mash them with a fork until smooth before adding to the wet ingredients, and the texture stays tender.
- Use Warm Oil for Smooth Batter: Heat the vegetable oil to about 100°F (just warm to the touch) before mixing it with the eggs and sugar. This helps emulsify everything faster and cuts down on lumps—no one wants to scrape the bowl after.
- Don’t Overmix the Dry Ingredients: Once you add the flour to the wet mix, stir just until combined—maybe 10-12 strokes max. Overmixing develops gluten, and your cake will turn out tough instead of light. Think "just enough to disappear."
- Bake Until the Center Cracks: The cake’s done when a toothpick comes out clean and the center springs back slightly when pressed. I learned this the hard way—underbaking leaves a gummy mess, while overbaking dries it out. Pull it at 340°F for 30-35 minutes, then check.
Wine and beer pairings for this recipe
Sweet Wine Pairings
For this banana cake with its rich chocolate ganache, I recommend a Moscato d'Asti from Italy—its light sweetness and floral notes complement the banana's natural sweetness without overpowering the chocolate.
A Riesling from Germany with a touch of residual sugar also works beautifully, especially if you prefer a slightly drier profile. 🍷
If you're serving this at a celebration, a Late Harvest Gewürztraminer from Alsace adds a luxurious touch with its lychee and rose aromas that harmonize perfectly with the caramelized banana flavors. For a budget-friendly option, White Zinfandel provides enough sweetness to match the dessert while keeping costs low.
Rich Chocolate Beer Pairings
A Belgian Dubbel like Westmalle Dubbel pairs wonderfully with the chocolate ganache, as its caramel and dark fruit notes enhance the dessert's depth. The beer's slight sweetness balances the banana's natural sugars, creating a delightful contrast. 🍺
For a lighter option, try a Chocolate Stout such as Guinness—its roasted malt flavors complement the chocolate frosting while the creamy texture mirrors the ganache's smoothness.
If you prefer something more hoppy, a Honey Brown Ale with its malty sweetness can bridge the gap between the cake and frosting beautifully.
Coffee Pairing
Since this dessert feels indulgent, a dark roast coffee like a French Press brew with its bold, slightly bitter notes cuts through the richness perfectly. The coffee's depth enhances the chocolate ganache, creating a satisfying contrast.
I love serving this with a mocha latte—the espresso's intensity pairs beautifully with the banana cake's sweetness. ☕
Seasonal Variations
In summer, opt for a sparkling Moscato to keep the dessert feeling light and refreshing. The bubbles cleanse your palate between bites, making each slice feel special.
For fall, a Port wine or Tawny Port with its nutty, caramelized notes mirrors the seasonal flavors and adds warmth to the experience. 🍂
During the holidays, a Spiced Chai Tea with its cinnamon and cardamom notes complements the cake's natural sweetness and adds a festive touch. The warmth of the tea enhances the dessert's cozy appeal, making it perfect for gatherings.

Frequently asked questions
Why do the bananas need to be overripe for this cake?
Overripe bananas with brown spots contain more natural sugars and a deeper flavor, which creates that signature moist texture and rich taste. The extra moisture also helps keep the cake tender even after baking. Look for bananas that are soft to the touch with dark brown spots—they're perfect for this recipe!
Can I substitute the vegetable oil with another fat? Yes! You can use melted coconut oil or apricot jam (¼ cup) instead of vegetable oil. For extra richness, swap it for melted butter (¼ cup), though the cake will have a slightly different texture. Just
How do I fix a cake that's too dense?
If your cake turns out dense, it's likely from overmixing or underbaking. Next time, fold the dry ingredients just until combined (a few streaks are fine) and bake for the full 40-45 minutes. For a quick fix, slice the cake thinly and serve with extra ganache—it'll still taste delicious!
Can I make this cake ahead of time?
The cake batter can be mixed and refrigerated overnight, then baked straight from the fridge (add 5-10 minutes to baking time). The ganache should be made fresh, but you can assemble the cake up to 2 days ahead and store it covered at room temperature. For best results, bring it to room temperature before serving.
What's the best way to store leftovers?
Keep leftovers in an airtight container in the fridge for up to 5 days. To revive slices, warm them in the microwave for 10-15 seconds—this makes the ganache smooth again. For longer storage, freeze slices wrapped in plastic for up to 3 months. Thaw overnight in the fridge before enjoying.
