Apple Banana Bundt Cake Recipe: Spiced Vanilla Frosting and Moist Layers

This apple banana bundt cake recipe delivers the perfect balance of spiced sweetness and tender layers—no dry crumbs in sight. 🍏 The secret lies in blending ripe bananas with finely diced apples, creating a naturally moist crumb that stays fresh for days.

I’ve baked this cake countless times for family gatherings, and it’s always the first to disappear.

What sets this apart is the moist texture—no greasing the pan required, thanks to a simple oil-and-flour technique. The apples add subtle tartness, while the bananas keep the crumb tender.

Topped with a swirl of vanilla frosting, it’s the kind of dessert that feels like a hug in cake form.

Perfect for brunch, potlucks, or a cozy weekend treat, this bundt cake serves 8–10 and bakes in just 50 minutes. Pair it with a scoop of vanilla ice cream for the ultimate indulgence. Let’s get baking!

Ingredients for apple banana bundt cake

Ripe bananas and apples make this bundt cake impossibly moist and fragrant—no dry crumbs here.

The bananas and apples are non-negotiable. Use bananas that are just past ripe—they mash easily and add natural sweetness. For apples, Honeycrisp or Fuji stay firm when diced, but any crisp variety works. I always grab organic at Whole Foods for fewer pesticides, but the regular grocery store stuff is fine too. The key is to dice them smaller than 1/4-inch pieces—they should disappear into the cake without a trace. Freshly grated nutmeg makes all the difference here—pre-ground loses potency fast.

No ripe bananas? Use 1/2 cup unsweetened applesauce instead, but reduce the apples to 1 medium. Short on apples? Substitute with 1 cup diced pear, but add an extra pinch of cinnamon. The frosting can be made ahead—just whip the cream and powdered sugar together when ready. For a dairy-free option, use coconut cream and reduce the powdered sugar to 2 1/2 cups. And if you're really in a pinch, vanilla ice cream on top makes this cake taste like a million bucks anyway.

This cake keeps for 3 days at room temperature, wrapped tightly in plastic. For longer storage, freeze the unfrosted cake for up to 2 months—thaw overnight in the fridge, then add frosting. The frosting itself lasts 1 week in the fridge, covered. I always make a double batch of frosting—one for the cake, one for toast. And trust me, the leftovers are even better the next day—the flavors meld beautifully.

Step-by-step instructions for apple banana Bundt cake

Here's how to create a perfectly moist cake with tender fruit layers and velvety frosting.

Peel the 3 medium ripe bananas and mash them thoroughly in a mixing bowl until completely smooth. Core and finely dice the 2 medium apples (skin on) into small, even pieces—about ¼-inch cubes. Toss the diced apples with 1 teaspoon of the granulated sugar and let them sit while you prepare the batter. This helps draw out their juices and prevents them from sinking to the bottom.

Here's the thing—ripe bananas are key for moisture. If they're not perfectly ripe (just slightly soft with brown speckles), mash in a splash of lemon juice to prevent browning. The apples should be firm but not hard—overly soft ones will turn mushy during baking. Let the fruit mixture sit for 5 minutes while you mix the batter; this jumpstarts the flavor extraction.

In a large bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, 2 teaspoons ground cinnamon, ½ teaspoon ground nutmeg, and ½ teaspoon salt. Sift the flour mixture directly into the bowl to avoid clumps—this ensures a light, airy texture. In a separate bowl, combine the 2 whole large eggs, 0.75 cup melted unsalted butter, 0.5 cup vegetable oil, 2 cups granulated sugar, 2 teaspoons vanilla extract, and 1 teaspoon vanilla bean paste. Mix until smooth and fully incorporated.

I like to use a stand mixer for this step—it emulsifies the wet ingredients beautifully. The vanilla bean paste adds depth that regular extract can't match. If your butter isn't fully melted, microwave it in 10-second bursts until just liquid. Overheating will cook the eggs and ruin the batter. The mixture should be thick but pourable—like a rich cake batter.

Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Avoid overmixing—stop as soon as the flour disappears. Gently fold in the prepared fruit mixture using a spatula, being careful not to break up the banana too much. The batter will be thick and slightly streaky with fruit pieces—this is perfect for that classic Bundt texture.

Here's where it gets fun—taste the batter before baking. If it needs more sweetness, add 1-2 teaspoons more sugar. The fruit should be evenly distributed, but don't worry if you see some chunks—this cake thrives on those pockets of flavor. Let the batter rest for 10 minutes at room temperature while you preheat the oven to 350°F. This resting period helps the flour hydrate fully and prevents cracking.

Lightly grease a 10-12 cup Bundt pan with vegetable oil and dust with flour, tapping out the excess. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 50-60 minutes until a toothpick inserted in the center comes out clean and the top is golden brown. Don't overbake—this cake is delicate and will continue cooking slightly as it cools.

The cake is done when the edges pull away from the pan and the top springs back gently when touched. If the top browns too quickly, tent loosely with foil after 30 minutes. I always check for doneness at the 50-minute mark—your oven might run hot, so start checking early. Let the cake cool in the pan for 15 minutes before transferring to a wire rack to cool completely.

In a chilled mixing bowl, whip the 0.75 cup cold heavy whipping cream to soft peaks—it should hold its shape when the whisk is lifted. Gradually add the 3 cups powdered sugar and 1 teaspoon vanilla extract, mixing on high speed until stiff peaks form. Fold in the 1 teaspoon vanilla bean paste at the very end for that extra layer of flavor. The frosting should be thick enough to hold its shape but still pipe smoothly.

Here's the secret to perfect frosting—use very cold cream straight from the fridge. If it's too warm, the frosting will be grainy. Also, don't overbeat it or you'll get butter instead of fluffy frosting. For extra stability, chill the frosting for 15 minutes before piping onto the cooled cake. This ensures clean, professional-looking swirls that won't slide off.

Essential equipment for apple banana bundt cake

Bundt Pan Essentials

You’ll need a 10-12 cup Bundt pan for this recipe—I use a Wilton Bundt pan because it has excellent heat distribution and intricate ridges. If you don’t own one, a nonstick Bundt pan (like Cuisinart) works well too, but greasing is still required.

Avoid dark-colored pans—they can over-brown the cake. 🍰

Mixing Tools

A stand mixer (like KitchenAid) or hand mixer makes this recipe easier, especially for the frosting. For the batter, a whisk works fine if you’re mixing by hand, but a mixer ensures even emulsification.

I also recommend a spatula for gently folding in the fruit to avoid overmixing. A fine-mesh sieve helps sift the dry ingredients smoothly for a lighter texture.

Measuring Tools

Precision matters in baking! Use a liquid measuring cup for the oil and melted butter, and a dry measuring cups with a level edge for the flour and sugar. A microplane is perfect for grating fresh nutmeg—pre-ground loses flavor quickly.

For the frosting, a piping bag with a star tip creates those professional swirls. Don’t skip measuring the fruit—3 medium bananas and 2 medium apples are key for moisture and texture.

Oven Thermometer

Ovens vary wildly in accuracy, so I always use an oven thermometer (like Thermoworks) to confirm your oven hits 350°F. Many ovens run 10-25°F hotter than set, which can dry out your cake.

Place the thermometer near the center rack while preheating—this ensures your cake bakes evenly and stays moist. 🌡️

Cooling Gear

Let the cake cool in the pan for 15 minutes before transferring to a wire cooling rack. This prevents the cake from sticking and collapsing. A small offset spatula helps loosen the edges if it sticks.

For the frosting, chill it in the fridge for 15 minutes before piping—this keeps it stable. A parchment-lined tray underneath catches drips while the cake cools completely.
