Key Ingredients for the Perfect Banana Upside Down Cake
Creating this delectable banana upside down cake starts with understanding the role each ingredient plays. Many of these pantry staples are probably already in your kitchen! While the full ingredient list is detailed in the recipe card below, here are some important notes on the key components that bring this cake to life:
Bananas: The star of the show! For the cake batter, choose *overripe bananas* – those with plenty of brown spots on their skins. Their elevated sugar content provides intense banana flavor and contributes significantly to the cake’s moist texture. For the beautiful topping, opt for *ripe bananas* that are still firm enough to hold their shape when sliced. They should be yellow with a few brown flecks, but not fully brown and mushy. This ensures defined, attractive slices after baking.
Butter: Essential for both the rich caramel topping and the tender cake batter. You can use either regular unsalted butter for classic flavor or a high-quality vegan butter substitute if you’re making a dairy-free version. Both salted and unsalted butter work, but if using salted, you might slightly reduce the added salt in the cake batter. The butter in the topping helps create that golden, gooey caramel layer.
Brown Sugar: This is critical for the caramelized topping. Brown sugar, with its molasses content, provides a deeper, richer flavor and helps create that signature sticky, sweet, and slightly chewy caramel layer that coats the bananas. It also gives the topping its beautiful golden-brown hue.
All-Purpose Flour: The structural backbone of our cake. For those looking to make this cake gluten-free, a 1-to-1 gluten-free flour blend that specifically includes xanthan gum is an excellent substitute. Xanthan gum helps provide elasticity and structure that gluten typically offers, ensuring your gluten-free cake is still wonderfully tender and not crumbly.
Cornstarch: A secret ingredient for a truly tender crumb. Adding a small amount of cornstarch to the flour mixture helps to slightly reduce the gluten development, resulting in a cake that is exceptionally soft and delicate without being overly dense or dry.
Fine Sea Salt: A pinch of salt is crucial for balancing the sweetness and enhancing all the other flavors in the cake. It deepens the banana taste and prevents the cake from tasting bland or overly sweet.
Baking Soda & Baking Powder: These are our leavening agents, responsible for the cake’s light and airy texture. Baking soda reacts with acidic ingredients (like sour cream and bananas) to create lift, while baking powder provides an additional boost, ensuring a perfectly risen and tender cake.
Granulated Sugar: Used in the cake batter to provide sweetness and help achieve that delicate, moist crumb. It also aids in caramelization during baking, contributing to the cake’s overall browning.
Sour Cream: A game-changer for moisture and a subtle tang. Sour cream adds richness and tenderness to the cake batter. Its acidity also works with baking soda to create lift. If you don’t have sour cream, plain Greek yogurt is a fantastic substitute. For a dairy-free option, surprisingly, mayonnaise can be used – it provides the necessary fat and emulsification without dairy, resulting in a similarly moist texture.
Milk: Adds essential liquid to the batter, contributing to its consistency and moisture. Whole milk is recommended for richness, but any plain non-dairy milk (like almond or soy) works beautifully for a dairy-free version without compromising the final texture.
Large Eggs: Act as binders, providing structure and richness to the cake. They also contribute to the cake’s leavening and help create a smooth, even texture.
Avocado Oil: Chosen for its neutral flavor and ability to keep the cake exceptionally moist. Oils tend to keep cakes moist longer than butter alone, and avocado oil is a healthy, versatile choice. You can also use other neutral oils like vegetable or canola oil.
Vanilla Extract: A classic flavor enhancer that complements the banana beautifully. A good quality vanilla extract adds warmth and depth to the cake’s overall profile.

Expert Tips for Making the Best Banana Upside Down Cake
While this banana upside down cake recipe is wonderfully straightforward, a few key tips can elevate your baking experience and ensure a flawless, delicious result every time. Follow these guidelines for perfection:
Generously Grease Your Cake Pan: This step is non-negotiable for a successful upside-down cake. Before adding your caramel and bananas, make sure to thoroughly grease the bottom and sides of your cake pan with butter or a non-stick cooking spray. This crucial layer acts as a release agent, ensuring that your beautiful caramelized topping and moist cake slide out cleanly onto your serving plate without sticking. Avoid using parchment paper for the bottom, as it can leave undesirable indentations on your delicate banana slices, detracting from their smooth, golden appearance.
Allow the Cake to Rest Before Flipping: Patience is a virtue, especially with upside-down cakes. After the cake comes out of the oven, it’s vital to let it cool in the pan for about 10 to 15 minutes before attempting to invert it. This resting period allows the cake structure to set and, more importantly, gives the hot caramel topping a chance to slightly firm up and absorb into the cake. If you try to flip it too soon, the caramel might be too liquidy and run off, or the cake might tear. If you’ve used vegan butter in the topping, which can be softer, extend the cooling time in the pan to about 20-30 minutes for optimal results.
Choose a Deep Cake Pan: The rich, buttery caramel topping can become quite bubbly and active during baking. To prevent any messy overflows in your oven, it’s highly recommended to use a cake pan with higher sides, ideally around 2 inches deep. If your pan isn’t quite deep enough, or if you want extra insurance, place the cake pan on a sturdy baking sheet lined with aluminum foil. This simple trick will catch any caramel that might bubble over the edges, keeping your oven clean and making cleanup a breeze.
Don’t Overmix the Batter: When combining your wet and dry ingredients for the cake, mix only until just combined. Overmixing can develop the gluten in the flour too much, leading to a tough, dense cake. A few small lumps are perfectly fine and will disappear during baking, resulting in a tender and fluffy crumb.
Use the Right Bananas for Each Part: As mentioned in the ingredients section, the type of banana matters. For the cake batter, the browner and spottier, the better – this maximizes flavor and moisture. For the topping, use ripe but firm bananas to ensure they maintain their shape and create those visually appealing slices. A medium ripeness is key for the topping.
Test for Doneness Correctly: To check if your cake is done, insert a toothpick into the very center of the cake, making sure it goes through the cake batter and not just into a banana slice or a pocket of caramel. The toothpick should come out clean or with a few moist crumbs attached. If it comes out with wet batter, continue baking for a few more minutes and retest.
Prepare Your Pan First: Have your greased pan with the caramel and banana slices ready *before* you start mixing the cake batter. This ensures that once your batter is mixed, you can immediately pour it over the topping and get it into the oven. This prevents the leavening agents from losing their potency while the batter sits around.

Ingredients
Topping
- 6 tablespoons unsalted butter
- ½ cup brown sugar
- 3 to 4 medium bananas sliced vertically
Cake
- 1 cup all-purpose flour
- 3 tablespoons cornstarch
- ¾ teaspoon fine sea salt
- ½ teaspoon baking soda
- 1 teaspoon baking powder
- ½ cup granulated sugar
- ¼ cup sour cream
- ¼ cup milk
- 2 large eggs
- 2 tablespoons avocado oil
- ¾ cup mashed banana
- 1 teaspoon vanilla extract
Instructions
-
Preheat your oven to 350°F (175°C). Ensure your oven is fully preheated for even baking.
-
Grease a 9-inch round cake pan thoroughly with butter or non-stick spray, making sure to cover both the bottom and sides. Set this aside.
-
In a small saucepan, melt the unsalted butter for the topping over low heat. Once melted, remove from heat and stir in the brown sugar until well combined. Spread this buttery brown sugar mixture evenly into the bottom of your prepared cake pan. Arrange the vertically sliced medium bananas over the brown sugar mixture in a decorative pattern. Set the pan aside.
-
In a separate small bowl, whisk together the dry ingredients for the cake: all-purpose flour, cornstarch, fine sea salt, baking soda, and baking powder. Whisk well to ensure all ingredients are evenly distributed, then set this dry mixture aside.
-
In a large mixing bowl, combine the wet ingredients: whisk together the large eggs, avocado oil, granulated sugar, sour cream, milk, and vanilla extract until smooth and well-incorporated.
-
Gradually add the dry ingredients mixture to the wet ingredients. Stir gently until just combined. Be careful not to overmix; a few small lumps are acceptable. Finally, fold in the mashed banana, stirring just enough to distribute it throughout the batter.
-
Carefully pour the cake batter over the sliced bananas and brown sugar mixture in the prepared pan. Spread it gently and evenly. Bake for 30 to 35 minutes, or until a wooden toothpick inserted into the center of the cake comes out clean. Baking times may vary depending on your oven, so keep an eye on it.
-
Once baked, remove the cake from the oven. Let it cool in the pan on a wire rack for 10-15 minutes (or 20-30 minutes if using vegan butter for the topping). This allows the caramel to set and the cake to firm up. After cooling, carefully invert the cake onto a serving plate. If any bananas stick, gently re-arrange them with a spatula. Serve warm or at room temperature.

Serving Suggestions for Your Banana Upside Down Cake
While this banana upside down cake is undeniably delicious on its own, a few simple additions can elevate it into an even more indulgent dessert experience. Here are some serving suggestions to make your cake truly shine:
- A Scoop of Vanilla Ice Cream: The classic pairing! The cold, creamy vanilla ice cream provides a delightful contrast to the warm, moist cake and sticky caramel.
- A Dollop of Whipped Cream: Light and airy, whipped cream adds a touch of elegance and balances the sweetness of the caramel topping.
- A Drizzle of Extra Caramel Sauce: If you’re a true caramel lover, a little extra warm caramel sauce never hurt anyone!
- Fresh Berries: A sprinkle of fresh raspberries or blueberries can add a burst of tartness and a beautiful color contrast.
- A Cup of Coffee or Tea: For a simple yet satisfying treat, enjoy a slice with your favorite hot beverage.

Storage Instructions for Banana Upside Down Cake
To keep your delicious banana upside down cake fresh and moist for as long as possible, proper storage is key. The caramel topping will keep the cake wonderfully tender, but here’s how to ensure it stays at its best:
- Room Temperature: Store any leftover cake in an airtight container at room temperature for up to 2 days. This is perfect if you plan to finish it quickly. The cake’s moisture content ensures it remains delicious without refrigeration for a short period.
- Refrigeration: For longer storage, transfer the cake to an airtight container and refrigerate for up to 4 days. Chilling the cake can make the caramel slightly firmer, but the flavors will still be outstanding.
- Freezing: If you want to enjoy a slice even further down the line, this cake freezes well! Wrap individual slices or the entire cooled cake (if uncut) tightly in plastic wrap, then an additional layer of aluminum foil. Store in the freezer for up to 2-3 months. When ready to enjoy, thaw in the refrigerator overnight and then bring to room temperature, or warm gently.
You can serve the cake chilled, which is surprisingly refreshing, or warm individual slices slightly in the microwave for 15-30 seconds to bring back that gooey caramel and warm, comforting flavor. Whichever way you prefer, this cake remains a treat!
Frequently Asked Questions (FAQs)
Here are answers to some common questions about making and enjoying banana upside down cake:
- Why did my cake stick to the pan? This is usually due to insufficient greasing of the pan or trying to flip the cake too soon. Ensure your pan is very well greased with butter or non-stick spray, covering all surfaces. Also, allow the cake to cool in the pan for the recommended time (10-15 minutes, or longer for vegan butter) before inverting. The caramel needs to set slightly to release cleanly.
- Can I use under-ripe bananas? While you can, it’s not recommended for the cake batter. Under-ripe bananas lack the sweetness and intense banana flavor needed for a truly moist and flavorful cake. For the topping, however, slightly firmer ripe bananas are ideal to hold their shape.
- Can I add nuts or chocolate chips? Absolutely! Chopped walnuts or pecans can be added to the cake batter for extra crunch and flavor. Chocolate chips would also be a delicious addition for a banana-chocolate combination. Fold them in at the very end when mixing the batter.
- What if I don’t have sour cream? Plain Greek yogurt is a great 1:1 substitute for sour cream, offering similar moisture and tang. For a dairy-free alternative, mayonnaise can be used to provide fat and moisture.
- Can I make this cake in a different pan size? A 9-inch round pan is specified, but you might use an 8-inch pan, in which case the baking time might be slightly longer (add 5-10 minutes) as the cake will be thicker. Conversely, a larger 10-inch pan might bake faster. Always monitor for doneness with a toothpick. For square pans, ensure it has high sides.
- Is it necessary to preheat the oven? Yes, always preheat your oven. Baking in a properly preheated oven ensures even heat distribution from the start, which is critical for consistent baking and proper leavening.
