Desserts
This applesauce banana cake recipe delivers the perfect balance of tender crumb and warm spice notes that keep slices moist for days. The secret lies in replacing half the oil with unsweetened applesauce, which adds natural sweetness while keeping the texture impossibly tender.
I developed this version after years of testing—it’s the one my family always asks for seconds on.
The cake features two distinct layers: a rich banana cake base infused with cinnamon and nutmeg, topped with a buttery streusel that caramelizes beautifully. Unlike traditional banana cakes, this version stays moist for up to 5 days when stored properly, making it ideal for meal prep or holiday gatherings.
The streusel adds a delightful crunch that contrasts perfectly with the soft cake beneath.
What makes this recipe stand out is its adaptability—swap regular flour for almond flour for a gluten-free option, or use coconut oil instead of butter for a vegan twist.
The warm spices and subtle sweetness from the applesauce create a comforting flavor profile that’s both nostalgic and sophisticated. Each bite delivers that perfect balance of moisture and texture.
Ready in just 350°F for about 35-40 minutes, this cake is simple enough for beginners but impressive enough for dinner parties. The streusel topping adds an extra layer of flavor and visual appeal, ensuring every slice looks as good as it tastes.
Here’s how to make it perfectly every time.
Ingredients for applesauce banana cake
This cake's secret is swapping half the oil for applesauce—moisture guaranteed.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Ripe Bananas 🍌 | 3 large | Mashed completely, no lumps |
| Unsweetened Applesauce 🍎 | ½ cup | No sugar added preferred |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Light or dark |
| Unsalted Butter 🧈 | ½ cup | Softened to room temp |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🌿 | 1 tbsp | High-quality preferred |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground ideal |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated preferred |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Old-Fashioned Oats 🌾 | 1 cup | Blended into flour |
| Packed Brown Sugar 🍚 | ¼ cup | For streusel topping |
| All-Purpose Flour 🌾 | ½ cup | For streusel topping |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for streusel |
The bananas are non-negotiable—ripe with brown spots ensures maximum sweetness and creaminess. Trader Joe's often has perfectly ripe ones, or check the back of the bunch at Whole Foods. For the applesauce, unsweetened is key—Mott's or Wellsley Farms are reliable brands. The butter matters too: Plugrá or Land O'Lakes work perfectly, but avoid margarine—it won't caramelize like real butter. Pre-measure everything before mixing to avoid lumps, especially with the brown sugar.
No applesauce? Unsweetened applesauce from a pouch works in a pinch, or mashed sweet potato at half the amount for moisture. Short on bananas? Substitute with mashed ripe pear—just reduce the sugar by 1 tbsp. The streusel can be made ahead and stored in the fridge for 5 days, saving time on baking day. For a gluten-free version, swap the all-purpose flour for Bob's Red Mill 1:1 Gluten-Free Flour. The oats in the streusel add texture—don't skip blending them into flour, or you'll get gritty bits.
Store the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days if you want it to last longer. The streusel topping stays crisp for 2 days at room temperature, but if you're prepping ahead, freeze the cake (without frosting) for 3 monthsroom temperature before slicing—it's more forgiving that way.

Step-by-step instructions for applesauce banana cake
Here's how to create a perfectly moist cake with tender layers and a warm spice streusel topping.
Prepare the Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans, lining the bottoms with parchment paper. In a large mixing bowl, combine the 2.5 cups all-purpose flour, 1 teaspoon baking soda, 0.5 teaspoon salt, 2 teaspoons ground cinnamon, and 0.5 teaspoon ground nutmeg. Whisk these dry ingredients together until fully combined and set aside.
In a separate large bowl, mash the 3 large ripe bananas until completely smooth with no lumps remaining. Stir in the 0.5 cup unsweetened applesauce, 1 cup granulated sugar, 0.5 cup packed brown sugar, 0.5 cup softened unsalted butter, 2 whole large eggs, and 1 tablespoon pure vanilla extract until the mixture is smooth and well blended. Gradually add the dry ingredients to the wet mixture, mixing just until combined—do not overmix.
Bake the Cake Layers
Divide the batter evenly between the two prepared cake pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and spring back gently when touched. Rotate the pans halfway through baking for even browning.
Remove the cakes from the oven and let them cool in their pans for 10 minutes. Then transfer them to a wire rack to cool completely. This cooling step is crucial for achieving clean layers when assembling. If the cakes cool too quickly, they may crack or become too dry.
Make the Streusel Topping
While the cakes are cooling, prepare the streusel topping in a medium bowl. Combine the 1 cup old-fashioned oats, 0.5 cup all-purpose flour, 0.25 cup packed brown sugar, and 0.25 cup cold cubed unsalted butter. Using your fingers or a pastry cutter, work the mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining.
Add the 2 teaspoons ground cinnamon and 0.5 teaspoon ground nutmeg to the streusel and mix well. The topping should be dry but hold together when pressed. Spread half of the streusel evenly over the first cake layer, then add a thin layer of your favorite fruit preserves or jam if desired—this is optional but adds extra moisture and flavor.
Assemble and Bake the Cake
Place the second cake layer on top of the first, pressing down gently to create an even surface. Sprinkle the remaining streusel evenly over the top layer, pressing down lightly to help it adhere. Bake the assembled cake at 350°F for 15-20 minutes until the streusel is golden brown and the cake is heated through.
Remove from the oven and let the cake cool completely on a wire rack before slicing. The streusel should be crisp on top but still tender when bitten into. Serve warm with a dollop of whipped cream or a scoop of vanilla ice cream for the perfect balance of textures and flavors.
Pro Tips For Making Applesauce Banana Cake
- Mash Bananas First: I learned this the hard way—skipping the mash and just slicing bananas into the batter leaves you with dense, uneven pockets of undercooked fruit. Use a fork to break them down completely, then press through a fine-mesh strainer to remove skins and seeds. This also keeps your batter smoother and prevents a gummy texture.
- Preheat Pan & Grease Well: This cake’s moist but sticky, so resist the urge to skip the greasing. Use a mix of softened butter and flour (or nonstick spray) on your pan, then sprinkle a thin layer of flour inside. Tap out the excess—this guarantees easy release and a clean slice. (Yes, even if you’re impatient like me, give it 30 seconds to sit after greasing.)
- Measure Applesauce Precisely: Unsweetened applesauce varies wildly in thickness. If yours is runny, thicken it with 1 tablespoon of flour mixed into the batter. Too thick? Thin it with 1 tablespoon of water. The goal is a consistency like heavy cream—anything else throws off the cake’s crumb and moisture balance.
- Bake Until Slightly Under: This cake’s done when the edges pull away from the pan but the center still has a tiny give. Overbaking turns it dry, and that’s a fast track to sad leftovers. Pop it out 2–3 minutes early, tent with foil, and let it rest 5 minutes before slicing. (Your future self will thank you.)
Make-ahead tips for leftovers
Prep Ahead Strategy
Assemble the entire cake (except final baking) up to 24 hours in advance. Wrap the unbaked cake layers and streusel separately in plastic wrap, then refrigerate. This prevents the cake from drying out while keeping the streusel crisp.
When ready to bake, simply assemble and finish in the oven—just 15-20 minutes at 350°F. 📅
Streusel Make-Ahead
Prepare the streusel topping 3 days ahead and store it in an airtight container at room temperature. The oats stay fresh and the spices retain their aroma. For extra insurance against drying, place a slice of bread in the container to absorb any moisture.
When baking day arrives, simply crumble and sprinkle—no extra prep needed. ✨
Freezer-Friendly Layers
Freeze the baked cake layers (without streusel) for up to 3 months by wrapping each layer individually in plastic wrap, then aluminum foil. Thaw overnight in the fridge before assembling.
The streusel can be added fresh after thawing for maximum crispness. This method works perfectly for holiday baking when you need to prepare ahead. ❄️
Portion Control
Slice the fully baked cake into individual portions and store them in a single-layer airtight container. This prevents smashing and keeps the streusel from getting soggy.
Reheat slices in the microwave for 10-15 seconds to restore freshness. I like to pack these for lunches—they travel beautifully and taste like homemade. 💡
Frosting Flexibility
Make your frosting 1 week ahead and store it in the fridge. For cream cheese frosting, simply whip the ingredients together when ready to use. For buttercream, soften the butter at room temperature before mixing.
This saves time on baking day and ensures your cake looks as good as it tastes. 🎂
Garnish Prep
Prepare any fresh garnishes like sliced almonds or chopped nuts 1 day ahead and store them in a sealed container. Toast them just before serving to maintain freshness and enhance flavor.
A sprinkle of cinnamon or a drizzle of honey can also be added right before serving for that restaurant-quality finish. 🌟

Frequently asked questions
Why does this recipe use applesauce instead of oil?
The applesauce replaces half the oil to create a lighter, more tender cake while adding natural sweetness and moisture. This swap keeps the cake moist for up to 5 days without making it dense. The banana also contributes natural sugars, balancing the applesauce's mild flavor.
Can I make this cake without bananas?
Yes! Substitute 3 ripe pears (mashed) or 1 cup unsweetened applesauce + 1/2 cup pumpkin puree. Reduce the sugar by 1 tbsp if using pears. The texture will be slightly denser, but still delicious. For a vegan version, use flax eggs (1 tbsp ground flax + 3 tbsp water per egg).
How do I keep the streusel from getting soggy?
Bake the cake layers completely, then cool them fully before adding streusel. For extra protection, sprinkle a thin layer of powdered sugar between layers. The final 15-20 minute bake at 350°F will crisp the streusel perfectly. Store the cake in an airtight container with a paper towel underneath to absorb moisture.
Can I use this recipe for a single-layer cake?
Omit the second layer and bake the batter in a single 9-inch pan for 30-35 minutes. Top with all the streusel before the final 10-minute bake. This works great for quick desserts or when you want a simpler presentation. The flavor remains the same—just adjust the portion size.
What's the best way to reheat slices?
For maximum crispness, reheat individual slices in the oven at 300°F for 3-5 minutes. Microwave for 10-15 seconds if short on time, but cover with a damp paper towel to prevent drying. Never reheat in the toaster—it'll make the streusel rubbery.
