Essential Ingredients for the Perfect Banana Upside Down Cake
One of the beauties of this banana upside down cake recipe is its reliance on readily available ingredients. You’ll likely find most of what you need already stocked in your pantry or refrigerator. While the complete, detailed list is conveniently located in the recipe card below, let’s dive into some specific notes on a few key components to ensure your cake turns out absolutely perfect.
The Star: Bananas
Bananas are, of course, the heart of this recipe, and using the right ripeness is crucial for different parts of the cake:
- For the Cake Batter: You want overripe bananas – those with plenty of brown spots on their peels. These bananas are sweeter, softer, and incredibly fragrant, providing the essential moisture and intense banana flavor that makes the cake so tender and delicious. Don’t be shy about using bananas that look past their prime for eating raw; they are perfect for baking!
- For the Topping: For the visually appealing caramelized layer, opt for ripe but firm bananas. These should still be yellow with perhaps a few brown spots, but firm enough to hold their shape beautifully when sliced. This ensures they create neat, attractive slices for the top (which becomes the bottom) of your cake.
Fat & Flavor: Butter
Butter plays a dual role here: creating the rich caramel topping and contributing to the cake’s tender crumb and flavor. You have flexibility:
- Regular Butter: Both salted and unsalted butter work wonderfully. If using salted butter, you might consider slightly reducing the added salt in the cake batter, but typically, the amount is negligible.
- Vegan Butter: To make this recipe dairy-free, a good quality vegan butter substitute can be used for both the topping and the cake batter. Ensure it’s a stick butter (not spread) for best results in baking.
Building the Structure: All-Purpose Flour & Cornstarch
The combination of these flours is key to the cake’s delightful texture:
- All-Purpose Flour: This forms the primary structure of our moist cake. For those looking for a gluten-free option, a 1-to-1 gluten-free flour blend (ensure it contains xanthan gum) is an excellent substitute and performs beautifully.
- Cornstarch: A secret weapon for a wonderfully tender cake crumb! Adding cornstarch to your flour mixture helps to soften the protein in the flour, resulting in a lighter, more delicate texture that truly melts in your mouth.
Moisture & Tang: Sour Cream
Sour cream is a fantastic ingredient for adding moisture and a slight tang that balances the sweetness of the cake:
- Full-Fat Sour Cream: Provides richness and ensures a super moist cake.
- Greek Yogurt: Plain, full-fat Greek yogurt can be used as a direct substitute for sour cream, offering a similar tang and moisture.
- Mayonnaise (Dairy-Free Option): For a dairy-free version, mayonnaise might seem unconventional, but it works surprisingly well! It provides the necessary fat and emulsification to keep the cake moist without dairy.
Liquid Gold: Milk
Milk helps bring the batter together and contributes to the overall moisture.
- Whole Milk: Recommended for the richest flavor and best texture.
- Non-Dairy Milk: Any plain non-dairy milk (almond, soy, oat) can be used as a suitable substitute for a dairy-free version.
Other Essential Ingredients:
- Brown Sugar (for topping): Dark or light brown sugar will work, providing depth of flavor and that signature caramel sweetness.
- Granulated Sugar (for cake): Balances sweetness in the cake batter.
- Eggs: Large eggs bind the ingredients, add moisture, and help with leavening. Ensure they are at room temperature for better emulsification.
- Avocado Oil: A neutral oil that contributes to the cake’s moistness without imparting strong flavors. Vegetable oil or canola oil can also be used.
- Vanilla Extract: Essential for enhancing all the other flavors in the cake. Use pure vanilla extract for the best taste.
- Baking Soda & Baking Powder: The dynamic duo for leavening, ensuring a light and airy cake.
- Fine Sea Salt: A pinch of salt balances the sweetness and brings out the full depth of flavor.

Expert Tips for a Flawless Banana Upside Down Cake
Achieving a perfect banana upside down cake is simpler than you think! Follow these tried-and-true tips to ensure your cake comes out of the pan beautifully and tastes incredible every time:
- Thoroughly Grease Your Cake Pan – No Parchment Paper! This step is non-negotiable for a clean release. Generously grease your entire 9-inch round pan, especially the sides, with softened butter or baking spray. Unlike other cakes, avoid lining the bottom with parchment paper for the topping. Parchment paper can stick to the soft, caramelized bananas and leave unsightly indentations, detracting from the cake’s smooth, glossy finish. A well-greased pan is your best friend here.
- Allow Adequate Resting Time Before Flipping. Patience is a virtue, especially with upside-down cakes! Once your cake is out of the oven, resist the urge to flip it immediately. Allowing it to cool in the pan for about 10 minutes is crucial. This cooling period allows the caramel topping to set slightly, preventing it from sticking to the pan or running everywhere when inverted. If you’ve used vegan butter in the topping, which can be a bit softer, extend this resting time to 20-30 minutes for optimal stability.
- Opt for a Deep Cake Pan. The delicious caramel topping can get quite bubbly and active in the oven. To prevent any messy overflows, it’s highly recommended to use a cake pan with higher sides, ideally around 2 inches deep. As an extra precaution, you can place your cake pan on a baking sheet lined with aluminum foil. This simple trick will catch any rogue caramel that might bubble over, saving your oven from sticky spills and making cleanup a breeze.
- Don’t Overmix the Batter. For a tender and moist cake, mix your dry ingredients into your wet ingredients until *just* combined. Overmixing develops the gluten in the flour, which can lead to a tough, dry cake. A few small lumps are perfectly fine!
- Ensure Room Temperature Ingredients. Eggs, sour cream, and milk should all be at room temperature. This allows them to emulsify better with the other ingredients, creating a smoother, more uniform batter and a finer crumb in the finished cake.
- Distribute Bananas Evenly for the Topping. Arrange your sliced bananas in a single, even layer over the caramel mixture. This ensures every slice of cake gets a beautiful banana topping and that the caramel distributes evenly.
- Test for Doneness. A toothpick inserted into the center of the cake should come out clean, or with a few moist crumbs attached. If it comes out with wet batter, continue baking in 2-3 minute increments until done.

Storing Your Banana Upside Down Cake for Maximum Freshness
To keep your delicious Banana Upside Down Cake tasting its best, proper storage is key:
- Room Temperature: For up to 2 days, you can store the cake in an airtight container at room temperature. This helps maintain its moist texture.
- Refrigerator: If you plan to keep it longer, store it in an airtight container in the refrigerator for up to 4 days. The caramel and bananas will firm up slightly when chilled.
- Freezing: This cake freezes beautifully! Once completely cooled, wrap the entire cake or individual slices tightly in plastic wrap, then again in aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator and bring to room temperature or warm slightly before serving.
- Serving: While it’s perfectly delightful straight from the fridge (especially on a hot day!), many prefer it slightly warm. You can gently reheat individual slices in the microwave for 15-30 seconds or in a low oven (300°F / 150°C) for about 10-15 minutes until just warmed through.
Frequently Asked Questions About Banana Upside Down Cake
Q: Can I use underripe bananas for the cake batter?
A: While you can use slightly less ripe bananas for the topping (as long as they are firm), for the cake batter, it’s highly recommended to use overripe bananas with plenty of brown spots. These bananas are sweeter and provide the necessary moisture and intense banana flavor that makes the cake so tender and delicious.
Q: My cake stuck to the pan, what went wrong?
A: The most common reason for sticking is insufficient greasing of the pan. Make sure to generously grease the entire pan (bottom and sides) with butter or baking spray. Also, ensure you let the cake cool for the recommended 10-30 minutes before inverting. This allows the caramel to firm up slightly and release cleanly.
Q: Can I add nuts or chocolate chips to the cake?
A: Absolutely! Chopped walnuts or pecans are a fantastic addition to the cake batter, providing a lovely crunch and nutty flavor. Chocolate chips also pair wonderfully with banana. Fold about ½ to ¾ cup of your desired additions into the batter just before pouring it over the bananas.
Q: Can I freeze banana upside down cake?
A: Yes, this cake freezes well! Once completely cooled, wrap the entire cake or individual slices tightly in plastic wrap, then again in aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator and bring to room temperature or warm slightly before serving.
Q: What kind of pan is best for this cake?
A: A 9-inch round cake pan with at least 2-inch high sides is ideal. The higher sides help contain the bubbling caramel during baking. A sturdy metal pan will conduct heat evenly for best results.
