Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or spray with non-stick baking spray.
- In a large mixing bowl, mash the very ripe bananas thoroughly with a fork until mostly smooth but with a few small lumps remaining. Ensure the bananas are as ripe as possible (brown spots are great!) for maximum sweetness and flavor.
- Add the entire package of yellow cake mix to the bowl with the mashed bananas.
- Pour the undrained can of crushed pineapple, including all its juice, into the bowl with the bananas and cake mix. The pineapple juice is crucial for the cake’s moistness and flavor.
- Using an electric mixer on low speed, or a sturdy spatula, mix the ingredients until just combined. Be careful not to overmix; a few lumps of banana are perfectly fine. Overmixing can lead to a tougher cake.
- Pour the batter evenly into the prepared 9×13 inch baking pan.
- Bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The cake should be golden brown on top.
- Remove the cake from the oven and place it on a wire rack to cool completely in the pan. Cooling completely is important for the cake to set properly and for easy serving.
- Once cooled, slice and serve. For an extra touch, top each slice with a dollop of whipped cream and a sprinkle of chopped nuts, or a simple dusting of powdered sugar.
Cooking Tips and Variations
For the absolute best results with this incredibly simple banana cake, the ripeness of your bananas is paramount. Don’t be afraid of bananas that are heavily speckled with brown or even mostly brown; these are the ones that will provide the most intense banana flavor and natural sweetness, reducing the need for any added sugar. The riper they are, the easier they’ll mash and the more fragrant your cake will be. When mixing the batter, resist the urge to overmix. Once the dry streaks of cake mix disappear and the ingredients are just combined, stop mixing. Overmixing develops gluten in the flour, which can lead to a dense, tough cake rather than the moist, tender crumb we’re aiming for. The crushed pineapple, with all its juice, is the secret weapon for moisture and a subtle tangy sweetness, so do not drain it!
Regarding your baking pan, a 9×13 inch pan is ideal for the specified baking time and cake thickness. If you opt for a different size, such as two 8-inch round pans or a bundt pan, you’ll need to adjust the baking time accordingly. Smaller pans will bake faster, while a bundt pan might require a slightly longer time. Always perform the toothpick test to ensure doneness. To keep your cake fresh, once it has cooled completely, cover it tightly with plastic wrap or aluminum foil. It will stay wonderfully moist at room temperature for up to 3 days, or you can refrigerate it for up to a week. For longer storage, slices can be individually wrapped and frozen for up to 3 months; thaw overnight in the refrigerator or at room temperature.
This 3-ingredient banana cake is also incredibly adaptable, allowing for delightful variations to suit your taste. For an added layer of flavor and texture, consider stirring in ½ cup of chocolate chips or shredded coconut into the batter before baking. These additions complement the banana and pineapple beautifully. If you’re looking for a more decadent finish, a simple glaze made from powdered sugar and a splash of milk or pineapple juice can be drizzled over the cooled cake. Alternatively, a classic cream cheese frosting would elevate this humble cake to a celebratory dessert. For a more sophisticated twist, a sprinkle of cinnamon or nutmeg can be added to the cake mix before combining with the wet ingredients, enhancing the warm, comforting spices. Don’t be afraid to experiment and make this easy recipe your own!
Storage and Reheating
Once your delicious 3-ingredient banana cake has completely cooled, proper storage is key to maintaining its incredible moistness and flavor. If you plan to consume it within 2-3 days, you can store the cake at room temperature. Simply cover the baking pan tightly with plastic wrap or aluminum foil, ensuring no air can get in to dry out the cake. If your kitchen tends to be warm, or if you’ve added any dairy-based toppings (like cream cheese frosting), it’s best to refrigerate the cake. When refrigerating, store the cake in an airtight container or keep it covered in its pan. It will stay fresh for up to 5-7 days in the refrigerator.
For longer storage, this banana cake freezes beautifully. Once the cake is completely cool, cut it into individual slices or larger portions. Wrap each slice tightly in plastic wrap, then again in aluminum foil, or place them in a freezer-safe airtight container or freezer bag. This double-wrapping prevents freezer burn and helps maintain moisture. Frozen banana cake can be stored for up to 3 months. To enjoy a frozen slice, simply thaw it overnight in the refrigerator or at room temperature for a few hours. You can also gently warm individual slices in the microwave for 15-30 seconds for a warm, comforting treat. Avoid reheating the entire cake in the oven as it can dry out; individual microwave reheating works best if you desire warmth.
Frequently Asked Questions
Can I use under-ripe bananas for this recipe?
While you technically can, it is highly recommended to use very ripe bananas (with brown spots) for this recipe. Ripe bananas are sweeter, more flavorful, and easier to mash, which contributes significantly to the cake’s taste and moist texture. Under-ripe bananas will result in a less sweet cake with a milder banana flavor.
Do I need to drain the crushed pineapple?
Absolutely not! The recipe specifically calls for undrained crushed pineapple. The juice from the pineapple is a crucial ingredient that contributes to the cake’s incredible moisture and adds a subtle tangy sweetness, balancing the richness of the bananas and cake mix. Draining the pineapple would make the cake much drier.
Can I make this cake in advance?
Yes, this 3-ingredient banana cake is an excellent make-ahead dessert. It actually tastes even better the next day as the flavors have more time to meld. Once cooled, store it properly as described in the “Storage and Reheating” section. It’s perfect for potlucks, parties, or just having a delicious treat ready for a busy week.
What if I don’t have yellow cake mix? Can I use another flavor?
While yellow cake mix is recommended because its mild flavor complements the banana and pineapple perfectly, you could experiment with other plain cake mixes like white or vanilla. However, flavors like chocolate or strawberry cake mix would likely overpower the delicate banana and pineapple notes, changing the character of the cake significantly.
