Ingredients for banana fudge cake recipe jamie oliver
Simple pantry staples transform into Jamie Oliver's legendary banana fudge cake—rich chocolate meets caramelized banana magic.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for lighter texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Ripe Bananas 🍌 | 3 medium | Slightly overripe, mashed |
| Large Eggs 🥚 | 2 whole | Room temperature for even baking |
| Vanilla Extract 🌸 | 2 tsp | Pure extract, not imitation |
| Baking Powder 🍞 | 1 ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cocoa or higher |
| Whole Milk 🥛 | ½ cup | Room temperature |
| Heavy Whipping Cream 🥛 | 1 cup | Chilled for whipping |
| Powdered Sugar 🍚 | 1 cup | For dusting |
| Chopped Walnuts 🌰 | ½ cup | Optional garnish |
The bananas are everything here—ripened until just soft (black spots on the peel, no mush). Grab 3 medium from the produce section, or if they're still firm, pop them in a paper bag with an apple overnight. For the chocolate, 70% cocoa or higher makes those swirls truly decadent—Ghirardelli or Lindt are my go-tos, but any good-quality chips work. The butter? Full-fat only—this isn't the time for low-fat shortcuts. Room temperature is key for both butter and eggs, so take them out 30 minutes before baking.
No ripe bananas? 2 medium bananas + 1 tbsp brown sugar in a warm pan for 5 minutes mimics caramelization. Swap dark chocolate for semi-sweet chips if that's what you've got, but the cocoa percentage drops the richness. Out of baking powder? 1.5 tsp baking soda + 1 tbsp cream of tartar works in a pinch. The walnuts are totally optional but add crunch—Trader Joe's pre-chopped saves time if you're in a hurry. For the cream, whipped to soft peaks is ideal, but don't overbeat it or you'll get butter.
This cake stays moist for 4-5 days wrapped at room temperature, but honestly? Day 2 is peak flavor—the fudge swirls soften beautifully. For gifting, slice and wrap individually with parchment. Freezes up to 3 months (wrap tightly in foil first). Pro tip: Sprinkle powdered sugar right after serving—it catches the cream's drips like magic. Leftovers? Toasted walnuts on top turn them into breakfast cake the next morning.

Step-by-step instructions for Jamie Oliver's banana fudge cake
Watch this decadent cake transform from batter to rich, moist perfection with chocolate swirls and caramelized banana.
👨🍳 Step 1: Prepare the Banana Fudge Batter
Preheat your oven to 350°F and grease a 9-inch round cake pan generously with butter, then line the bottom with parchment paper. In a large mixing bowl, combine the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 1.5 tsp baking powder, and 0.5 tsp salt. Whisk until evenly distributed—this ensures a light, airy texture.
In a separate bowl, mash the 3 medium ripe bananas until completely smooth, with no lumps remaining. This step is crucial for that signature moistness. Add the mashed bananas to the dry ingredients along with the 1 cup room-temperature unsalted butter, 2 whole large eggs, 2 tsp vanilla extract, and 0.5 cup whole milk. Mix on medium speed until just combined—you should still see small flour streaks. Overmixing develops gluten, which can make your cake dense.
🍳 Step 2: Create the Chocolate Swirl Layer
In a microwave-safe bowl, melt the 1.5 cups dark chocolate chips in 30-second intervals, stirring between each interval until completely smooth. Let it cool slightly—it should be warm but not hot to the touch. This prevents the chocolate from cooking the batter and creating a bitter taste.
Pour half of the banana batter into your prepared cake pan and spread it evenly. Spoon the melted chocolate over the batter, then carefully swirl it with a knife in a circular motion. This creates those beautiful marbled chocolate swirls throughout the cake. Pour the remaining banana batter over the chocolate and gently swirl again to blend the layers. The contrast between the rich chocolate and sweet banana will be incredible!
🔥 Step 3: Bake to Golden Perfection
Bake the cake for 45-50 minutes until a toothpick inserted into the center comes out clean with just a few moist crumbs. The edges should be golden brown while the top still looks slightly underbaked—this ensures a moist interior. I know it's tempting to open the oven early, but resist! The cake needs that full baking time to develop its structure.
Once baked, let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This gradual cooling prevents cracking and allows the flavors to meld together beautifully. The cake should have a slightly domed top with those gorgeous chocolate swirls visible throughout.
🥘 Step 4: Prepare the Cream Cheese Frosting
While the cake cools, whip the 1 cup heavy whipping cream in a chilled bowl until soft peaks form. In a separate bowl, beat the 1 cup powdered sugar until smooth, then gradually add it to the whipped cream. This creates a light, airy base for our frosting. Add the 2 tsp vanilla extract and mix until fully incorporated.
Gently fold in the cooled melted chocolate from earlier (about ½ cup of the reserved chocolate) to create a marbled effect in the frosting. This adds depth of flavor and ties the cake together beautifully. The frosting should be thick enough to hold its shape but still spreadable.
🍽️ Step 5: Assemble and Garnish
Once the cake is completely cool, spread the cream cheese frosting evenly over the top and sides. I like to use an offset spatula for smooth, even coverage. Sprinkle the 0.5 cup chopped walnuts over the top just before serving—they add a delightful crunch that contrasts perfectly with the soft cake.
Slice and serve immediately for the ultimate experience. Each bite should deliver a perfect balance of moist banana cake, rich chocolate swirls, and creamy frosting. This cake is especially magical when served with a dollop of whipped cream or a scoop of vanilla ice cream—trust me, it's a match made in dessert heaven!
Pro Tips For Making Banana Fudge Cake Recipe Jamie Oliver
- 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 press through a fine-mesh sieve or blend briefly with 1 tablespoon of the flour to get silky smoothness. No one wants to bite into a surprise banana chunk.
- Cream Butter and Sugar Slowly: Jamie’s recipe relies on that classic butter-sugar foam, but rushing it means air gets trapped unevenly. Beat the butter and sugar on medium speed for at least 3–4 minutes until it’s pale and fluffy—not just combined. This isn’t the time to speed through; it’s the foundation for a light, tender crumb.
- Don’t Overmix the Batter: After folding in the eggs and dry ingredients, stop mixing the second everything’s just combined. Overmixing develops gluten, which turns this cake into a chewy brick instead of its signature moist, fudgy texture. Two turns with a spatula is all it takes—yes, even if you’re impatient like me.
- Use Room-Temp Eggs and Butter: Cold eggs and butter create pockets of resistance in the batter, leading to uneven baking. Let both sit out for 30–45 minutes before starting—just until they’re soft to the touch but not warm. This ensures the cake rises evenly and has that signature jammy richness throughout, not just at the edges.
Dietary considerations for these flavors
Gluten-Free Adaptation
For a gluten-free version, swap the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. Use 2.5 cups of the blend, but add 1 extra tablespoon of xanthan gum to mimic gluten's structure. I've tested this with 3 extra minutes in the oven—gluten-free cakes often need that extra time to set properly. 💫
Dairy-Free Options
Replace the 1 cup unsalted butter with 1 cup dairy-free butter (like Miyoko's or Earth Balance) and use 1 cup full-fat coconut milk instead of whole milk. For the frosting, substitute 1 cup heavy whipping cream with 1 cup coconut whipped cream (chill a can of full-fat coconut milk overnight, scoop out the thick cream, and whip it). The texture stays light, but the flavor gains a subtle tropical note.
Lower Sugar Version
Reduce the 1.5 cups granulated sugar to 1 cup and replace the remaining ½ cup with ½ cup pure maple syrup or ½ cup unsweetened applesauce. The cake will still be moist but with a deeper caramel flavor from the bananas. I've found that using 1 extra ripe banana (4 total) helps maintain sweetness without extra sugar. The chocolate swirls stay rich because they're not competing with as much sweetness.
Vegan Considerations
For a fully vegan cake, use flax eggs (replace 2 eggs with 2 tbsp ground flaxseed + 6 tbsp water, mixed and rested for 5 minutes). Swap the dark chocolate chips for vegan chocolate (Enjoy Life brand works perfectly). The frosting becomes vegan whipped coconut cream (as mentioned above) with 1 tbsp lemon juice to stabilize it. The texture remains light, though slightly denser than the original.
Nut-Free Garnish
Skip the walnuts entirely or replace them with toasted coconut flakes (½ cup, lightly toasted in a dry pan for 3 minutes). For extra crunch without nuts, try crushed freeze-dried raspberries—they add a tart contrast that balances the richness. I've also used sea salt flakes (just a pinch) on top for a sophisticated finish that pairs beautifully with the chocolate.

Frequently asked questions about Jamie Oliver's banana fudge cake
Why does this cake need ripe bananas?
Ripe bananas with black spots on the peel are essential—they're sweeter and mash into a smoother, more flavorful puree. This creates the signature moist texture and caramelized sweetness that balances the rich chocolate. Overripe bananas (too mushy) can make the cake dense, while underripe ones won't be sweet enough to complement the fudge.
Can I make this cake in a different pan size?
Yes, but adjust the baking time. For an 8-inch pan, bake 35-40 minutes—the cake will be thicker and may need 5 extra minutes. For a 10-inch pan, bake 40-45 minutes—the wider surface area requires less time. Always check with a toothpick when in doubt!
What if my chocolate swirls don't look pretty?
Don't stress! Use a butter knife to gently drag lines through the batter before adding the second layer—this creates natural marbling. If the chocolate sinks too much, chill the batter for 15 minutes before baking. The contrast between the warm batter and cold chocolate helps it stay suspended.
How do I store leftovers without drying them out?
Wrap the cake tightly in plastic wrap, then place it in an airtight container. Store at room temperature for up to 3 days—the flavors actually improve! For longer storage, freeze slices individually wrapped in parchment for up to 3 months. Thaw at room temperature before serving.
Can I use fresh bananas instead of ripe ones?
Fresh bananas work, but they'll be less sweet and more watery. For best results, warm 2 medium fresh bananas in a dry pan for 5 minutes until soft, then mash. Add 1 tablespoon brown sugar to compensate for the lack of natural sweetness. The texture will be slightly less moist but still delicious!
