Ingredients for banana cake recipe jamie oliver
Jamie Oliver’s secret: perfectly ripe bananas and velvety buttercream transform simple ingredients into extraordinary cake magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 whole | Spotty and soft, not mushy |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Softened to room temp |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Pure Vanilla Extract 🌿 | 1 tbsp | High-quality, not imitation |
| Baking Powder 🧂 | 1 tsp | Freshly opened |
| Ground Cinnamon 🌶️ | 1 ½ tsp | Warm and aromatic |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Heavy Cream 🥛 | 1 cup | Cold for buttercream |
| Powdered Sugar 🍚 | 3 cups | Sifted for smooth frosting |
| Vanilla Bean Paste 🌿 | 1 tsp | For extra vanilla flavor |
| Unsalted Butter 🧈 | ½ cup | Cold for buttercream |
The bananas are non-negotiable—look for those with brown spots (the sweeter, the better). Trader Joe’s and Whole Foods often have the ripest selection, but your local market’s produce manager can point you to the best ones. If you’re baking ahead, store ripe bananas in the fridge overnight to intensify their flavor. The butter should be soft but not melted—press a finger in it and it should leave a slight indent. For the vanilla, Madagascar bourbon vanilla adds depth, but any pure extract works. Sift your flour and powdered sugar—no lumps in that buttercream!
No ripe bananas? Use 1/2 cup unsweetened applesauce per banana—it won’t be identical, but it’ll save your cake. Short on buttercream time? Whipped cream with powdered sugar works in a pinch (though it won’t hold as well). The baking powder needs to be fresh—test it by mixing 1 tsp with 1/4 cup hot water; if it fizzes, it’s good. For a nutty twist, fold in 1/2 cup chopped walnuts to the batter. And if you’re feeling fancy, swap the vanilla bean paste for a scraped vanilla bean**—trust me, the difference is worth it.
This cake keeps beautifully—wrap tightly in plastic wrap and store at room temperature for 3-4 days or refrigerate for up to 1 week. The buttercream? Make it a day ahead—it tastes even better after the flavors meld. For serving, garnish with extra caramelized banana slices (save 1 banana to bake separately at 350°F for 15 mins) and a sprinkle of cinnamon sugar. Freeze portions for up to 3 months—just thaw at room temp before serving. Pro tip: Slice with a warm knife for cleaner cuts!
Why You'll Love This Recipe
- No Fuss Mix-In: I swear by this recipe’s simplicity—just mash those bananas, fold in the dry ingredients, and let the butter and eggs do the heavy lifting. No sifting, no creaming, no stress. Honestly, it’s the kind of cake that makes me feel like I actually baked something when I didn’t.
- Moist Magic: That perfect balance of caramelized bananas and buttery richness? It’s like a hug in cake form. The sugar pulls the banana’s natural sweetness into something dangerously addictive, and the eggs keep it tender without being gummy. (Yes, even on a Tuesday night.)
Step-by-step instructions for Jamie Oliver's banana cake
Here's how to create a lusciously moist banana cake with those signature caramelized banana swirls.
👨🍳 Step 1: Mash the Bananas and Mix Wet Ingredients
Start by mashing the 3 whole ripe bananas in a large mixing bowl until completely smooth—no lumps allowed. The bananas should be spotty and soft, not mushy, for that perfect texture. Add the 1 cup softened unsalted butter and mix until fully combined.
In a separate small bowl, whisk together the 2 whole large eggs, 1 tbsp pure vanilla extract, and 1.5 cups granulated sugar until pale and slightly thickened. This creaming process incorporates air, which helps create that light, airy texture we're after. Pour this egg mixture into the banana bowl and stir gently to combine.
👨🍳 Step 2: Combine Dry Ingredients and Fold Gently
In another bowl, sift together the 2 cups all-purpose flour, 1.5 tsp ground cinnamon, 1 tsp baking powder, and 0.5 tsp salt. This sifting ensures a light texture and prevents lumps in the final cake. Gently fold the dry ingredients into the wet mixture using a spatula, mixing just until combined.
Here's the thing—overmixing develops gluten, which makes cakes tough. Stop mixing as soon as the flour disappears. The batter should be thick but pourable. For that signature swirl effect, divide the batter evenly between two 8-inch round cake pans lined with parchment paper.
🔥 Step 3: Bake Until Golden and Springy
Preheat your oven to 350°F and bake the cakes for 25-30 minutes, until a toothpick inserted into the center comes out clean and the tops are golden brown. I like to rotate the pans halfway through for even baking—this is especially important if your oven runs hot.
Don't open the oven door early to check! The sudden temperature change can cause the cakes to sink. When you do check, look for that beautiful domed shape and a springy texture when pressed gently in the center. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack.
🍳 Step 4: Make the Caramelized Banana Swirl
While the cakes cool, make the banana swirl by mashing 1 ripe banana (save the other two for the frosting) with 2 tbsp of the reserved cake batter. This creates a thick, spreadable mixture perfect for swirling. Spread this mixture evenly over one of the cooled cake layers.
Place the second cake layer on top and gently press down. The key here is to keep the layers level—this ensures even slices. For the swirl effect, use a knife to make a well in the center and pipe the remaining banana mixture around the edges, then swirl it into the center with the tip of the knife.
🥘 Step 5: Frost with Vanilla Buttercream
Beat the 0.5 cup cold unsalted butter until smooth, then gradually add the 3 cups powdered sugar, 1 cup heavy cream, 1 tbsp pure vanilla extract, and 1 tsp vanilla bean paste. Whip on high speed until light and fluffy—about 3-4 minutes. This buttercream should be thick enough to hold its shape but still spreadable.
Spread the buttercream evenly over the top and sides of the cake, then use a spatula to create a smooth finish. For extra flair, pipe decorative swirls on top using a star tip. The contrast between the creamy frosting and the caramelized banana swirls is what makes this cake so irresistible. Chill for 30 minutes before slicing to let the flavors meld.
Pro Tips For Making Banana Cake Recipe Jamie Oliver
- Mash Bananas Thoroughly: No streaks of whole banana in your batter—this isn’t a smoothie. Use a fork first to break them up, then press through a fine-mesh sieve or push through a tamper in a sieve to get rid of all the skin and fiber. Trust me, the texture of the cake will be actually moist, not just "sort of wet."
- Cream Butter and Sugar Properly: Jamie’s recipe relies on that classic butter-sugar combo for structure, so don’t just mix it until it’s "combined." Beat it on medium-high for 3–4 minutes until it’s pale, fluffy, and leaves a trail when the whisk pulls out. I learned this the hard way—under-creamed butter means a dense, cakey texture instead of that light, tender crumb.
- Don’t Overmix the Batter: Once you fold in the dry ingredients, stop as soon as they’re just incorporated. Overmixing develops gluten like you’re kneading bread dough, and that’s how you end up with a tough, chewy cake instead of the soft, pillowy one this recipe promises. Two turns of a spatula is all it takes—seriously.
- Use Room-Temp Eggs and Butter: Cold eggs and butter make the batter fight you. Let them sit out for at least 30 minutes before starting—20 minutes in a warm (not hot) oven works in a pinch. The cake will bake more evenly, and you won’t end up with a sunken center because the butter didn’t melt properly. (Yes, I’ve done that. No, you don’t want to.)
Make-ahead tips for this banana cake recipe jamie oliver
Pre-Baking Prep
Start your banana cake prep the night before for maximum flavor. Store the 3 ripe bananas in the fridge overnight—the cold temperature intensifies their natural sweetness and caramel notes. I like to peel them and wrap them individually in plastic wrap before refrigerating. This step makes a noticeable difference in the final cake's depth of flavor. 💫
Batter Make-Ahead
Mix the cake batter up to 24 hours ahead and store it in an airtight container in the refrigerator. The flavors meld beautifully overnight, and the batter develops a slightly tangy richness. When ready to bake, let it sit at room temperature for 30 minutes before dividing it between your pans. This prevents uneven baking from cold batter.
Banana Swirl Prep
Save 1 extra ripe banana for the caramelized swirl—this is what creates those irresistible jammy pockets. Mash it with 2 tbsp batter and keep it refrigerated until ready to use. The texture thickens slightly when chilled, making it easier to spread and swirl between layers. For extra caramelization, bake this banana separately at 350°F for 15 minutes before mashing.
Buttercream Ahead
The buttercream is best made 24 hours in advance—it develops a smoother texture and deeper vanilla flavor. Whip it together as directed, then store it in an airtight container at room temperature. If your kitchen gets warm, refrigerate it for up to 3 days, then let it soften slightly before using. I find it tastes even better after resting, with none of the graininess you sometimes get with fresh buttercream.
Layer Assembly
Assemble the cake layers up to 4 hours ahead of serving. Wrap the fully frosted cake tightly in plastic wrap and refrigerate. This gives the frosting time to set properly and prevents any soggy bottoms. When ready to serve, let it sit at room temperature for 20 minutes to soften slightly—this makes slicing much easier and more precise. The flavors will be fully developed by this point. ✨
Freezing Tips
For long-term storage, freeze the fully assembled cake (without frosting) for up to 3 months**. Wrap it tightly in plastic wrap and place it in an airtight freezer bag. When ready to serve, thaw it in the refrigerator overnight, then frost it fresh. The texture remains excellent, though the frosting is best made fresh for optimal consistency. For individual portions, freeze slices wrapped in parchment paper for quick treats.

Frequently asked questions
Can I use unripe bananas in this recipe?
The secret to Jamie Oliver's signature flavor is using perfectly ripe bananas—look for ones with brown spots and soft skin. Unripe bananas won't caramelize properly and will make the cake taste bland. If you only have firm bananas, let them sit at room temperature for 2-3 days to ripen first. For an emergency, you can substitute 1/2 cup unsweetened applesauce per banana, but the texture won't be identical.
How do I get the best caramelized banana swirl?
For those irresistible jammy swirls, save 1 extra ripe banana and bake it separately at 350°F for 15 minutes before mashing with 2 tbsp batter. This intensifies the caramelization. Spread it between layers while the cake is still slightly warm—it'll melt beautifully into the buttercream. For extra drama, use a knife to create swirls in a circular motion right before the frosting sets.
Can I make this cake in a single layer instead of two? For a single 9-inch round cake, use the full batter in one pan and bake for 35-40 minutes. Skip the layer assembly and frost the top only. The cake will be denser but still delicious. For a taller cake, use a 6-inch pan and bake for 45-50 minutes**, rotating halfway. Just
Why did my cake turn out dense instead of moist?
Overmixing the batter develops gluten, which makes cakes tough. Mix just until combined—stop when the flour disappears. Another common mistake is underbaking—always check with a toothpick (it should come out clean). For extra moisture, try adding 1 tbsp sour cream or yogurt to the batter. Also ensure your butter is softened but not melted, and your bananas are ripe but not mushy.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap and store at room temperature for 3-4 days, or refrigerate for up to 1 week. For longer storage, freeze slices wrapped in parchment paper for up to 3 months. The buttercream can be made ahead and stored at room temperature for 3 days or refrigerated for 1 week. Always bring refrigerated cake to room temperature before serving for the best texture.
