Banana Cake Recipe With 1 Cup Flour: Ultra-Moist Layers Without a Drop of Oil

This banana cake recipe with 1 cup flour delivers ultra-moist layers without oil or butter—just ripe bananas, eggs, and a few simple pantry staples. The secret lies in the egg yolks and applesauce, which replace fat while keeping the crumb tender and rich. I developed this version after years of testing banana cakes that turned out dry or dense, and this is the one that finally nailed the texture every time.

What makes this recipe stand out is the foolproof technique that ensures perfect moisture balance. The ripe bananas provide natural sweetness and moisture, while the applesauce adds body without heaviness. No oil means lighter layers, and the leavening agents (baking soda and baking powder) create just enough lift for a tender yet sturdy cake. The result? A cake that stays moist for days—no drying out, no gummy texture, just perfectly balanced flavor and crumb in every slice.

The cake bakes up with a golden, slightly domed top and a fine, even crumb that’s neither too dense nor too airy. It’s ideal for breakfast, dessert, or even a snack, and the natural banana flavor shines through without needing extra sugar. The frosting (if you choose to add it) is simple but enhances the cake’s richness, making it feel like a bakery-worthy treat without the fuss.

Whether you’re baking for a crowd or just craving a slice of comfort, this recipe delivers restaurant-quality results with minimal effort. The ingredients are straightforward, the method is simple, and the outcome is consistently delicious. Let’s get baking!

Ingredients for banana cake recipe 1 cup flour

Simple pantry staples and ripe bananas create ultra-moist cake layers without oil or butter.

The bananas are non-negotiable—overripe with brown speckles delivers the best moisture and sweetness. Grab them from the back of the bunch where they ripen first. For flour, King Arthur or Bob's Red Mill brands work best—they're finely milled and consistent. The applesauce should be unsweetened; Mott's or store-brand both work fine. I always measure my dry ingredients by weight for accuracy, but cups work in a pinch. The baking soda and powder need to be fresh—if your baking powder doesn't bubble when mixed with vinegar, toss it.

No applesauce? Pumpkin puree works at the same amount, though it adds slight earthiness. Out of walnuts? Pecans or almonds toast just as well. The vanilla extract matters—imitation vanilla lacks depth, so splurge on pure if you can. For a lighter texture, separate the egg yolks and beat them with sugar first, then fold in the whites at the end. The butter can be swapped for melted coconut oil if needed, though it does change the flavor slightly. Always use room-temperature eggs for even baking.

Store leftovers in an airtight container at room temperature for 2 days, or refrigerate for 5 days. The cake freezes beautifully—wrap tightly in plastic and foil for up to 3 months. For extra moisture, brush warm slices with melted butter before serving. This cake actually tastes better the next day as the flavors meld. Portion into single servings before freezing for easy grab-and-bake breakfasts.

Step-by-step instructions for banana cake with 1 cup flour

Here's the method for tender, ultra-moist banana cake layers without oil or greasy texture.

Mash the 2 cups ripe bananas thoroughly in a large mixing bowl until completely smooth with no lumps. I press through a fine-mesh sieve if any fibrous bits remain—this ensures a silky batter. In a separate bowl, whisk together the 1 cup all-purpose flour, 1 cup granulated sugar, 1 tsp baking soda, 1 tsp baking powder, 1 tsp ground cinnamon, and 0.5 tsp salt. Sifting the dry ingredients prevents dense layers.

Melt the 0.25 cup unsalted butter in a microwave-safe bowl for 30 seconds, then stir in the 0.5 cup unsweetened applesauce and 0.5 cup milk until smooth. This butter-applesauce blend replaces oil while maintaining moisture. The applesauce also adds subtle sweetness and tenderizes the crumb.

Add the mashed bananas to the dry ingredients and mix just until combined—about 15 strokes with a rubber spatula. Overmixing develops gluten and makes the cake tough. Pour in the melted butter mixture and mix again until smooth. Add the 2 whole eggs and 1 tsp vanilla extract, mixing gently until fully incorporated.

Here's where the magic happens: fold in the 0.5 cup optional chopped walnuts (if using) with a spatula. I recommend lightly toasting the walnuts first—just 2 minutes in a dry pan over medium heat—for enhanced flavor. The walnuts add texture contrast to the soft cake layers.

Preheat your oven to 350°F. Grease two 8-inch round cake pans with butter or line with parchment paper, then lightly flour. Divide the batter evenly between the pans and smooth the tops. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean and the edges pull away from the pan.

I've found that baking at this moderate temperature prevents a domed top while ensuring even cooking throughout. The applesauce helps regulate moisture release, so you won't get a dry cake even if slightly underbaked. Rotate the pans halfway through baking for even browning.

Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. This gradual cooling prevents cracking. While the cakes cool, prepare your filling—either a simple cream cheese frosting or a light banana cream made with whipped cream and mashed banana.

The key to ultra-moist layers is patience. Don't cut into the cake until it's completely cool—this ensures clean slices. If you're layering, use a serrated knife and dip it in hot water between slices to prevent crumbs. The applesauce and mashed bananas work together to keep these layers tender for days.

Pro cooking tips for banana cake recipe 1 cup flour

Banana Ripeness Matters

For ultra-moist layers, black-speckled bananas are non-negotiable—they're packed with natural sugars and moisture. I always check for soft spots and brown freckles before buying. If your bananas aren't ripe enough, place them in a paper bag with an apple overnight—the ethylene gas will speed up ripening. Never use bananas with large brown areas or mushy centers, as they'll make your cake taste bitter. 🍌

Egg Yolk Technique

Separate the egg yolks from whites and beat them with the sugar first until pale and thick—this creates a smoother batter. Then gently fold in the whites at the end to maintain airiness. I use a whisk attachment on low speed to avoid overbeating. This step prevents dense layers while keeping the cake tender. The yolks also help bind the moist ingredients without needing extra fat.

Applesauce Substitutions

No applesauce? Pumpkin puree works 1:1 but adds earthiness, or use Greek yogurt for tanginess. I've also had success with mashed sweet potato (½ cup) for a slightly caramel note. Avoid oil substitutes like vegetable oil—they make the cake greasy. The applesauce's fiber content actually improves texture by preventing gluten overdevelopment. 🍎

Baking Powder Test

Always test your baking powder first—mix 1 tsp with ¼ cup hot water. If it bubbles vigorously, it's fresh. Old baking powder won't rise properly, leading to dense cake. I keep mine in the freezer to preserve freshness. The double-acting variety (like Clabber Girl) gives two rises—one when wet, another when heated—which is perfect for banana cake's moisture-heavy batter.

Pan Prep Secrets

For perfect domed tops, grease pans with melted butter and dust with flour, tapping out excess. I use 8-inch round pans because they distribute heat evenly. If your oven runs hot, reduce temp to 340°F and check at 22 minutes. The butter-applesauce blend creates a natural nonstick surface, so you won't need extra flouring. Rotate pans halfway for even baking. 🔥

Moisture Lock Method

After baking, brush the warm cakes with melted butter while still in pans. This creates a moisture barrier that keeps slices tender for days. Store in an airtight container with a slice of bread to absorb excess moisture. I've kept this cake fresh for 5 days at room temperature without drying out. For freezing, wrap each layer individually in plastic before adding foil—this prevents freezer burn and makes slicing easier later. ❄️
