Ingredients for banana bundt cake recipe with cake mix
Transform a simple cake mix into a restaurant-quality dessert with these 14 easy ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Vanilla Cake Mix 🍞 | 1 box | Standard 15.25 oz box |
| Ripe Bananas 🍌 | 3 large | Mashed, 1 cup equivalent |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |

| Milk 🥛 | ½ cup | Whole milk for richness |
| All-Purpose Flour 🌾 | ½ cup | For streusel texture |
| Light Brown Sugar 🍚 | ½ cup | Packed, for caramelization |
| Old-Fashioned Rolled Oats 🥣 | ½ cup | Quick or regular oats |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for streusel |
| Ground Cinnamon 🌿 | 1 tbsp | For warm banana flavor |
| Salt 🧂 | ¼ tsp | Kosher or sea salt |

The bananas are non-negotiable—look for those with brown spots (that's ripe!) at Trader Joe's or local markets. Three large bananas should yield about 1 cup mashed, which is perfect for blending into the batter. The cake mix is the base, but don't skip the extra flour in the streusel—it creates that perfect crumbly texture. For the butter, Land O'Lakes or Plugrá are my go-tos, but any full-fat works. If you're in a pinch, you can use melted shortening, though the flavor won't be quite as rich.
No ripe bananas? Use 1 cup unsweetened applesauce—it keeps the moisture but adds a different flavor. Out of brown sugar? White sugar works at the same amount, though the streusel might not caramelize as much. The oats can be swapped for crushed graham crackers if you're out, but they add a nice chewiness. For the bundt pan, Wilton makes the best nonstick versions, but any well-seasoned pan works. If yours isn't nonstick, grease it extra well with the vegetable oil and flour—this is key for easy release. The powdered sugar is optional but adds that final touch of elegance.
This cake keeps beautifully for 3-4 days in an airtight container at room temperature, though it's best enjoyed fresh. For longer storage, wrap it tightly in plastic wrap and refrigerate for up to 1 week. The streusel topping stays crisp if you store it covered, but it's best served the day it's made. Slice it with a serrated knife for clean cuts—this cake is moist, so a regular knife will smash it. Leftovers reheat well in the microwave for 10 seconds to restore the streusel's crunch.
Why You'll Love This Recipe
- No Mix-Up Moments: I’ll admit, I’ve burned cake mixes before—this one’s forgiving. The ripe bananas add natural sweetness and moisture, so even if I forget to grease the Bundt pan just right, the cake still turns out tender. That buttery richness from the melted butter? It smooths out any rough edges.
- Banana Magic Boost: Honestly, the cake mix alone is fine, but those mashed bananas? They’re the MVP. The eggs bind everything together while keeping it light, and the milk makes it just moist enough—not dense, not dry. It’s like a hug in dessert form, especially when you slice into that swirl in the center.
- Breakfast or Dessert: Here’s what sold me—this cake is my go-to for lazy mornings and Sunday suppers. Serve it warm with a drizzle of honey for a quick breakfast, or dust it with powdered sugar for a fancy dessert. The butter and bananas make it satisfying either way, and it’s the perfect size for sharing (or not).
- Pantry Stash Winner: Between us, I keep a box of vanilla cake mix and a stash of overripe bananas just for this. It’s budget-friendly, uses what I’ve got, and leftovers reheat beautifully. Plus, the eggs and butter are staples, so I’m never scrambling for extra ingredients. Twenty minutes, one bowl—this is my secret weapon for when I need something reliable.
Step-by-step instructions for banana bundt cake
Transform simple ingredients into a moist, golden bundt cake with perfect layers.
👨🍳 Step 1: Prepare the Bundt Pan and Make the Cake Batter
Preheat your oven to 350°F and grease a 10-cup bundt pan thoroughly with 2 tablespoons vegetable oil. Dust it evenly with 2 tablespoons flour, tapping out any excess. This ensures easy release later. In a large mixing bowl, combine the 1 box vanilla cake mix, 2 whole large eggs, 0.5 cup milk, and 0.5 cup melted unsalted butter.
Use a hand mixer on low speed for 2 minutes until the batter is smooth and fully combined. The batter should be thick but pourable—if it looks too stiff, add 1 tablespoon milk at a time until it reaches the right consistency. Here's the thing—don't overmix, or you'll develop gluten and end up with a tough cake instead of the tender texture we're after.
🍳 Step 2: Fold in Bananas and Prepare the Streusel
In a separate bowl, mash the 3 large ripe bananas until smooth. You should have about 1 cup of mashed banana—no need to measure, just mash until completely smooth. Gently fold the banana mixture into the cake batter using a spatula, being careful not to deflate any air bubbles. This step is where that creamy promise comes to life.
In a medium bowl, combine the 0.5 cup old-fashioned rolled oats, 0.5 cup light brown sugar, 1 tablespoon ground cinnamon, 0.25 teaspoon salt, and the 0.25 cup cold cubed unsalted butter. Use your fingers to work the butter into the oat mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining. This creates the perfect streusel texture for that golden crown.
🥘 Step 3: Assemble and Bake the Bundt Cake
Pour half of the cake batter into the prepared bundt pan, spreading it evenly. Sprinkle about half of the streusel mixture over the batter, then add the remaining batter. Top with the remaining streusel, pressing down gently to ensure even distribution. The streusel should create a beautiful golden crown when baked—this is the moment that matters.
Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean. The cake is done when the edges pull away from the pan slightly and the top is golden brown. If you peek too early, the cake may collapse—trust the toothpick test. The first 30 minutes are critical for building structure, so don't open the oven door during this time.
⏰ Step 4: Cool and Finish with Powdered Sugar
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then carefully invert it onto a wire rack to cool completely. I know it's tempting to dig in right away, but patience here prevents a crumbly cake. The cooling process allows the cake to set properly and develop that perfect texture.
Once completely cool, dust the top generously with 0.5 cup powdered sugar using a fine-mesh sieve. This optional step adds that professional finish and balances the rich banana flavor. For best results, serve the cake at room temperature—this lets all the flavors meld together beautifully.
Pro Tips For Making Banana Bundt Cake Recipe With Cake Mix
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana chunks in your cake mix mean dense, uneven texture. Use a fork first, then push through a fine-mesh sieve (yes, even if it feels like overkill) to get silky smooth batter that blends right in.
- Grease That Bundt Pan: Butter the pan, then dust with flour—but don’t skip the sugar. A light coating of granulated sugar on the floured walls prevents sticking and gives the cake’s edges that perfect pull-apart texture. (Pro tip: Use a pastry brush for the butter—it’s faster than your fingers.)
- Wait for the Internal Temp: The box says "350°F for 50-60 minutes," but your oven’s hot spots lie. Pull the cake when the center reads 205-210°F—any lower, and you’ll have a gummy middle. If unsure, poke with a skewer; it should come out clean and the cake should spring back, not jiggle.
- Swap Milk for Buttermilk: The cake mix already has baking powder, but buttermilk’s acidity cuts through the sweetness and keeps the crumb tender. Mix 1 tablespoon vinegar or lemon juice into warm milk, let it sit 5 minutes—no extra effort, just better flavor. (I know, I know, but trust the process.)
Perfect pairings for this dish
Cream Cheese Frosting
This classic pairing elevates your bundt cake to bakery-level perfection. Beat 8 oz cream cheese (room temperature) with ½ cup unsalted butter until smooth. Gradually add 3 cups powdered sugar and 1 tsp vanilla extract, mixing until fluffy. Spread over the cooled cake—it balances the banana's sweetness with tangy richness. For extra flair, top with toasted pecans or banana slices. 💛
Caramel Glaze Drizzle
Warm 1 cup caramel sauce (store-bought or homemade) with 2 tbsp heavy cream until pourable. Drizzle generously over the cake's top and sides for a glossy finish. I love Smucker's caramel sauce for its smooth texture. Let it set for 10 minutes before slicing—this prevents a sticky mess. 🍯
Vanilla Ice Cream
Serve warm slices with a scoop of vanilla ice cream for a decadent dessert. The cold ice cream contrasts beautifully with the cake's warmth. I recommend Blue Bell vanilla or homemade for the best flavor. For a fancy touch, drizzle melted chocolate over the ice cream before serving. 🍦
Whipped Coffee Cream
For a coffee lover's twist, mix 1 cup heavy whipping cream, 2 tbsp powdered sugar, and 1 tbsp instant coffee granules. Whip until stiff peaks form, then dollop alongside cake slices. The coffee notes complement the banana's natural sweetness. Store-bought Coffee-Mate coffee creamer works in a pinch. ☕
Fresh Berries
Add a pop of color and freshness with sliced strawberries, blueberries, or raspberries. Arrange them on a plate around the cake or sprinkle over the top. The berries' acidity cuts through the cake's richness. Use Trader Joe's frozen berries if fresh aren't available—just thaw them first. 🍓
Spiced Whipped Cream
Infuse whipped cream with ½ tsp cinnamon and ¼ tsp nutmeg for a warm, aromatic pairing. Whip 1 cup heavy cream with 2 tbsp powdered sugar until soft peaks form, then fold in the spices. Pipe rosettes over cake slices for an elegant presentation. 🌿

Frequently asked questions
Can I use a different cake mix flavor?
Yes! While vanilla is ideal, you can swap for yellow or spice cake mix—just reduce the cinnamon in the streusel to ½ teaspoon to avoid overpowering. Avoid chocolate mixes, as the banana flavor won't shine through.
Why did my bundt cake stick to the pan?
This usually means the pan wasn't greased or floured properly. Always use 2 tablespoons oil + 2 tablespoons flour (tap out excess) and avoid nonstick sprays—they don't coat evenly. Let the cake cool 10 minutes in the pan before inverting for easier release.
How do I make this cake gluten-free?
Replace the cake mix with a 1:1 gluten-free vanilla mix (like Bob's Red Mill) and swap the all-purpose flour for ½ cup gluten-free 1:1 baking flour in the streusel. Use a dedicated bundt pan to avoid cross-contamination. The texture will be slightly denser but still moist.
Can I bake this in a regular round pan?
Use a 9-inch round or tube pan and reduce baking time to 35-40 minutes. The streusel will still caramelize beautifully, though the shape won't be as dramatic. For even baking, rotate the pan halfway through.
What's the best way to store leftovers?
Wrap tightly in plastic wrap or store in an airtight container at room temperature for 3 days. For longer storage, refrigerate for up to 1 week. Reheat slices at 350°F for 10 seconds to restore the streusel's crunch.
