A banana bundt cake made with cake mix is a quick and delicious way to use up ripe bananas and create a moist, flavorful dessert with minimal fuss. This method gives you the convenience of a supermarket cake mix while letting you customize the cake with real banana flavor and a beautiful bundt shape. Whether you’re baking for a family gathering, a potluck, or just want to treat yourself, this recipe streamlines the process so you don’t have to measure out flour, sugar, and leaveners from scratch. Before you start, make sure your bananas are very ripe (brown and spotty), your oven is preheated, and you have your bundt pan greased and ready to go. Let’s get baking!
What You’ll Need
- 1 box (about 15.25 oz) yellow or white cake mix (any major brand)
- 3 large ripe bananas (the riper, the better)
- 3 large eggs
- 1/2 cup vegetable oil (or melted butter, if preferred)
- 1/2 cup sour cream or plain Greek yogurt (for extra moisture)
- 1/2 cup granulated sugar (optional, for added sweetness)
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon (optional, for added flavor)
- 1/2 teaspoon salt
- Bundt pan (10-12 cups capacity)
- Nonstick cooking spray or butter and flour for greasing the pan
- Mixing bowls
- Electric mixer or whisk
- Rubber spatula
- Cooling rack
Step-by-Step
- Preheat your oven to 350°F (175°C). Ensure the rack is in the center position for even baking.
- Prepare the bundt pan by thoroughly greasing it with nonstick spray or butter and flour. Be sure to get into all the crevices to prevent sticking.
- Mash the bananas in a large bowl using a fork or potato masher until mostly smooth. Some small lumps are fine for texture.
- Combine wet ingredients: To the mashed bananas, add the eggs, oil, sour cream (or Greek yogurt), vanilla extract, and sugar (if using). Whisk together until fully combined.
- Add cake mix and dry ingredients: Sprinkle the cake mix, cinnamon (if using), and salt over the wet ingredients. Mix on low speed with an electric mixer or by hand with a whisk until just combined. Do not overmix; stop when there are no dry streaks.
- Scrape the batter into the prepared bundt pan, smoothing the top with a spatula. Tap the pan gently on the counter to release any air bubbles.
- Bake for 40-50 minutes, or until a skewer or cake tester inserted into the thickest part comes out clean or with a few moist crumbs. Baking time may vary depending on your oven and the exact pan size.
- Cool in the pan on a rack for 15-20 minutes. This allows the cake to firm up and release more easily.
- Invert the cake onto a wire rack by placing the rack over the pan, then flipping both together. Gently lift off the bundt pan. Allow the cake to cool completely before glazing or serving.
- Optional: Glaze or dust with powdered sugar once the cake is cool. A simple glaze can be made from 1 cup powdered sugar and 2-3 tablespoons milk or lemon juice.
- Slice and enjoy! Store leftovers tightly wrapped at room temperature for up to 3 days, or refrigerate for up to 5 days.
Common Mistakes
- Under-greasing the bundt pan: Bundt cakes are prone to sticking, especially with add-ins like banana. Always grease thoroughly, getting into every groove.
- Overmixing the batter: Mixing too much after adding the cake mix can make the cake dense and tough. Mix just until combined.
- Using bananas that are not ripe enough: Underripe bananas are less sweet and don’t mash well, resulting in less flavor and a chunkier texture.
- Not cooling the cake before removing from the pan: Trying to turn out the cake too soon can cause it to break apart. Allow it to rest in the pan for at least 15 minutes.
- Overbaking: Bundt cakes can dry out if left in the oven too long. Start checking at 40 minutes and remove when a skewer comes out clean or with a few moist crumbs.
- Ignoring pan size: Using a smaller or larger bundt pan than specified can affect baking time and may cause overflow or a squat cake.
Tips
- Enhance flavor: Add a handful of chopped walnuts, pecans, or chocolate chips to the batter for extra flavor and texture.
- Customize your glaze: Mix powdered sugar with milk for a classic glaze, or use lemon juice for a tangy finish. Cream cheese glaze is also delicious with banana.
- Check for doneness: Insert a wooden skewer or thin knife into the thickest part of the cake. It should come out clean or with a few moist crumbs, but not wet batter.
- Room temperature ingredients: Let eggs and sour cream come to room temperature before mixing. This helps the batter blend smoothly and rise properly.
- Storage: Keep the cake covered at room temperature for up to 3 days, or freeze slices (wrapped well) for up to 2 months. Thaw at room temperature before serving.
- Presentation: For a festive look, sprinkle chopped nuts or banana chips over the glaze, or dust with powdered sugar using a fine sieve.
Troubleshooting
- The cake stuck to the pan: If the cake won’t release, tap the pan gently on the counter. Run a thin knife around the edges and the center tube. If needed, let it cool longer in the pan, then try again. Next time, grease the pan more thoroughly and dust with flour or sugar before adding the batter.
- The cake is dense or gummy: This usually means the batter was overmixed or the bananas were too large/wet. Next time, use only three medium-large bananas and mix just until combined. Also, check that your leavening (in the cake mix) is not expired.
- The cake is dry: Overbaking is the main culprit. Check your oven’s accuracy with an oven thermometer and start testing for doneness at 40 minutes. Adding sour cream or Greek yogurt helps keep the cake moist.
- The cake overflowed: Bundt pans vary in capacity. If your pan is smaller than 10 cups, only fill it 3/4 full, and bake the extra batter as muffins or a mini loaf.
- The cake tastes bland: Some cake mixes are less flavorful. Add a teaspoon of cinnamon, a pinch of nutmeg, or a splash of banana extract to boost taste. Using vanilla or butter cake mix instead of plain yellow can also enhance flavor.
- The top is too brown: If the cake browns too quickly, tent the top loosely with foil during the last 15 minutes of baking.
Frequently Asked Questions
- Can I use a different flavor of cake mix?
- Yes! White, butter, or even spice cake mixes work well. Chocolate cake mix creates a banana-chocolate bundt.
- What if I don’t have sour cream or Greek yogurt?
- You can use plain yogurt, buttermilk, or even applesauce in equal measure. The cake will still be moist and tender.
- Can I add nuts or chocolate chips?
- Absolutely. Stir in up to 1 cup of chopped nuts or chocolate chips after mixing the batter. Lightly toss add-ins with flour to prevent sinking.
- How do I store banana bundt cake?
- Store at room temperature, tightly wrapped, for up to 3 days. For longer storage, refrigerate up to 5 days or freeze slices for up to 2 months.
- Do I need to adjust baking time for high altitude?
- At high altitude, increase oven temperature by 15–25°F and check for doneness 5–10 minutes earlier. Results may vary by location.
- Can I make this cake gluten-free?
- Yes, use a gluten-free cake mix and ensure all other ingredients are gluten-free. Texture may be slightly different, but it will still taste great.
