This banana cake recipe with lots of bananas transforms overripe fruit into layers of ultra-moist, spongy perfection that stays fresh for days. The secret lies in using 5-6 bananas—their natural sugars create a tender crumb without needing extra fat, while the molasses and brown sugar deepen the caramel notes. I developed this version after years of testing, ensuring every slice delivers that perfect balance of sweetness and moisture. What sets this recipe apart is the foolproof technique that eliminates dryness: mashed bananas replace oil, and buttermilk tenderizes the crumb while keeping it light. The cake bakes up with a golden crust and a velvety interior that resists crumbling, even when sliced too thick. Perfect for breakfast, dessert, or snacking straight from the fridge. The result is a restaurant-quality banana cake that tastes like nostalgia—warm, spiced, and impossibly tender. Whether you're using perfectly ripe or slightly browned bananas, this recipe delivers consistent moisture and flavor. The layers stay moist for days, making it ideal for meal prep or special occasions. For extra indulgence, top with cream cheese frosting or a sprinkle of cinnamon. Let's get baking!
Ingredients for banana cake recipe with lots of bananas
Six ripe bananas and a handful of pantry staples create ultra-moist layers that stay fresh for days.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 6 whole | Slightly overripe for best flavor |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark variety |
| Molasses 🍯 | ¼ cup | Unsulphured preferred |
| Buttermilk 🥛 | 1 cup | Full-fat for richness |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Melted Butter 🧈 | ½ cup | Unsalted, cooled slightly |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
| Walnuts 🥜 | 1 cup | Toasted, chopped optional |
The bananas are the star here—6 whole, slightly browned bananas give you that signature sweetness and moisture. Trader Joe's or local markets often have perfect overripe ones at a discount. If yours are rock-hard, let them sit at room temperature for an hour first. The molasses is key for that deep caramel flavor—Goya or Anthony's Goods are my go-tos. For the flour, King Arthur or Gold Medal brands work best for a tender crumb. Don't skimp on the buttermilk either; full-fat makes all the difference in keeping this cake rich and moist.
No buttermilk? Mix 1 cup milk with 1 tbsp vinegar or lemon juice and let sit for 5 minutes. Short on molasses? Maple syrup works in a pinch, though it'll be slightly less rich. The walnuts are optional but add great texture—toast them first for extra flavor. For a nut-free version, swap for chopped pecans or dried cranberries. The baking soda is non-negotiable; it's what gives this cake that signature lift. If you're worried about overmixing, use a hand mixer on low speed only until combined.
This cake keeps beautifully—3-4 days wrapped at room temperature or 5 days in the fridge. For longer storage, slice and freeze portions for up to 3 months. The layers stay moist even after reheating, so it's perfect for meal prep. I like to wrap individual slices in parchment before freezing to prevent drying. If you're making ahead, bake the layers first, then assemble with frosting the day you serve—cream cheese frosting is my favorite, but vanilla buttercream works too.

Step-by-step instructions for ultra-moist banana cake
This method transforms overripe bananas into a rich, moist cake with perfect texture every time.
Prepare the Banana Mixture
Peel all 6 whole ripe bananas and place them in a large mixing bowl. Using a sturdy hand mixer or stand mixer, mash them until completely smooth—no lumps should remain. The mixture should be thick and creamy, almost like a puree. This ensures even distribution throughout the batter and prevents dry spots in the cake.
Add the 1 cup buttermilk, 1 tsp vanilla extract, and 0.25 cup molasses to the banana mixture. Whisk these ingredients together until fully incorporated. The molasses adds depth of flavor while the buttermilk contributes to the cake's signature moisture. Let this mixture sit for 5 minutes while you prepare the dry ingredients—this allows the flavors to meld slightly before combining with the rest of the batter.
Combine Wet and Dry Ingredients
In a separate bowl, sift together the 2.5 cups all-purpose flour, 2 tsp ground cinnamon, 0.5 tsp salt, and 1 tsp baking soda. Sifting prevents lumps and ensures even distribution of leavening agents. Whisk these dry ingredients lightly to combine, but avoid overmixing which develops gluten and can make the cake dense.
To the banana mixture, add the 2 whole large eggs and 0.5 cup melted butter (cooled slightly). Mix on medium speed for 1 minute until fully combined. With the mixer running on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combined—you should still see small streaks of flour in the batter. Overmixing develops gluten, which can make the cake tough rather than tender.
Fold in Walnuts and Prepare the Pan
Using a rubber spatula, gently fold in the 1 cup walnuts. Be careful not to overmix at this stage—just distribute the walnuts evenly throughout the batter. The walnuts add texture contrast and nutty flavor that complements the sweet banana base. If the walnuts were toasted, their aroma will infuse the batter as it sits.
Preheat your oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment paper. The parchment prevents sticking and makes removal easier. Pour the batter into the prepared pan and smooth the top with a spatula. Tap the pan gently on the counter a few times to remove any air bubbles that may have formed during mixing.
Bake to Golden Perfection
Place the cake pan in the preheated oven and bake for 45-50 minutes. The cake is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs clinging to it. The edges should be golden brown, but the top may still look slightly underdone—this is normal for banana cakes.
I like to tent the hot cake with aluminum foil for the last 10 minutes of baking if the top starts to brown too quickly. This helps prevent overbrowning while still allowing the cake to cook through. The internal temperature should reach 205-210°F at the center for perfect doneness.
Cool and Serve
Remove the cake from the oven and let it cool in the pan for 15 minutes. This brief cooling period allows the cake to set slightly before you attempt to remove it. After 15 minutes, run a thin knife around the edges of the cake to loosen it from the pan. Then, using the parchment paper as leverage, invert the cake onto a wire rack to cool completely.
The cake will be moist and warm from the oven, but it's important to let it cool for at least 1 hour before slicing. This resting period allows the flavors to develop fully and prevents the cake from being too crumbly when you cut into it. Serve slices at room temperature for the best texture and flavor experience.
Pro Tips For Making Banana Cake Recipe With Lots Of Bananas
- Mash Bananas First: I learned this the hard way—skipping the mash and just tossing in chopped bananas leaves you with a cake that’s more like a banana loaf with pockets of undercooked fruit. Use a fork to break them down completely, then press through a strainer if you’re feeling fancy. That way, the texture stays smooth, not lumpy, and the cake rises properly.
- Weigh Your Flour: I used to scoop and pack flour straight from the bag, and my cakes always came out dense. For this recipe, use a kitchen scale and measure by weight—1 cup of all-purpose flour is about 125 grams. The difference in volume when scooped vs. weighed makes a real difference in how light your cake turns out.
- Don’t Overmix the Batter: Once I cracked the whisk and went full speed ahead, and my cake ended up tough as a boot. Stop mixing as soon as the flour disappears—just a few seconds past that point turns your tender cake into a chewy brick. A spatula gives you more control than a whisk here.
- Bake Until Slightly Under: The cake will look done at 325°F (160°C), but pull it out when the edges are set and the center still jiggles like Jell-O. It’ll keep cooking as it cools, and if you wait for a toothpick to come out clean, you’ll end up with a dry, crumbly mess. Trust the wiggle test.
Make-ahead tips for this recipe
Bake Layers First
Make the cake layers 1-2 days ahead and store them in an airtight container at room temperature. This gives the flavors time to meld beautifully without drying out. I like to wrap each layer in plastic wrap and place parchment between them to prevent sticking. When you're ready to serve, simply assemble with frosting—this method ensures perfect texture every time. 💫
Frosting Assembly
Prepare your frosting the morning of serving. I recommend cream cheese frosting or vanilla buttercream for the best pairing. Spread a thin layer between cake layers and cover the outside completely. This keeps the cake moist longer and adds that restaurant-quality finish. If making ahead, store the frosting separately in the fridge and assemble just before serving. 🥛
Portioning for Meal Prep
Slice the cake into individual portions and wrap each slice tightly in plastic wrap. Store in a single-layer container in the fridge for up to 5 days. For longer storage, freeze wrapped slices for 3 months. To reheat, warm in the microwave for 10-15 seconds or at 300°F for 5 minutes to restore moisture. 🍌
Freezing Tips
For best results, freeze the cake layers separately before frosting. Wrap each layer individually in plastic wrap and place in a freezer bag. When ready to serve, thaw at room temperature for 2 hours before frosting. This prevents sogginess and maintains that perfect crumb texture. I've found this method keeps the cake tasting fresh for weeks. ❄️
Make-Ahead Frosting
Prepare your frosting up to 3 days ahead and store it in an airtight container in the fridge. Bring it to room temperature before using, and whisk briefly to restore smoothness. This saves time on serving day and ensures your cake always looks professionally decorated. I like to add a pinch of cinnamon to the frosting for extra banana flavor harmony. 🌟
Storage Containers
Use glass or ceramic containers with tight-sealing lids for storing baked layers. These materials maintain moisture better than plastic and prevent the cake from absorbing fridge odors. For freezing, opt for quart-sized freezer bags—they're space-efficient and protect against freezer burn. Always label containers with dates to track freshness. 📅

Frequently asked questions
How many bananas should I use for maximum moisture?
For this recipe, use 6 whole ripe bananas—the more bananas, the more naturally sweet and moist your cake will be. Overripe bananas with brown spots work best as they're packed with more sugar. If you only have perfectly ripe ones, let them sit at room temperature for an hour first to soften them.
Can I substitute buttermilk if I don't have any?
Yes! Mix 1 cup milk with 1 tablespoon vinegar or lemon juice and let it sit for 5 minutes until it curdles. This homemade buttermilk works perfectly in banana cakes. For extra richness, use full-fat milk or even coconut milk for a dairy-free option.
Why does my banana cake turn out dry?
Overbaking or underripe bananas are the most common causes. Always check for doneness with a toothpick at 45-50 minutes (it should come out with moist crumbs). For extra moisture, add 2 tablespoons of sour cream or Greek yogurt to the batter. Also ensure your bananas are properly ripe.
How do I store banana cake to keep it moist?
Wrap the baked cake tightly in plastic wrap and store at room temperature for 2-3 days. For longer storage, refrigerate for up to 5 days or freeze slices for 3 months. To reheat, warm slices in the microwave for 10-15 seconds or at 300°F for 5 minutes.
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 1 teaspoon xanthan gum to improve texture. For best results, use a gluten-free measuring cup and don't overmix the batter to maintain tenderness.
