Banana Upside Down Cake
There is something quietly impressive about flipping a warm cake onto a plate and watching a glossy, caramelized topping reveal itself. Banana Upside Down Cake delivers exactly that moment, with golden-edged banana slices set in a buttery brown sugar glaze on top of a soft, moist homemade cake that tastes far more indulgent than the effort suggests.
This easy dessert works with pantry staples and ripe bananas you may already have sitting on the counter. The brown sugar layer melts into a sticky, toffee-like glaze while the cake bakes, and when you flip it out, the top looks lacquered and beautiful without any decorating skills. The batter itself is lightly spiced with cinnamon, kept moist with buttermilk or yogurt, and balanced so the sweetness does not tip into heavy.
What makes this cake feel so special is that caramelized banana top. It is chewy, fragrant, and rich in a way that plain banana bread never quite reaches. Let’s walk through every step.
These golden, glossy banana slices are what make the whole cake look showstopping the moment you invert it.

INGREDIENTS
HOW TO MAKE IT (Step by Step)
Preheat the oven to 350°F. Spray a 9-inch round baking pan with nonstick spray and set it on a sheet tray to catch any drips during baking, about 3 minutes.
In a small saucepan over medium heat, melt the butter and brown sugar together until liquified and slightly glossy, about 2 minutes. Pour evenly into the prepared pan. Pro tip: do not overcook the caramel on the stovetop, it will finish deepening in the oven while the cake bakes.
Peel the bananas and slice them lengthwise. Arrange them flat-side down over the brown sugar layer in a single, tight layer, about 3 minutes.
In a medium bowl, whisk together the flour, baking powder, cinnamon, and salt until evenly combined, about 2 minutes.
In a large bowl, whisk the oil, sugar, eggs, vanilla, and buttermilk together until smooth. Add the dry ingredients and stir until just combined. Do not overmix or the crumb will tighten up. Pro tip: a few small lumps in the batter are fine and actually keep the cake more tender once baked.
Pour the batter over the bananas and smooth the top with an offset spatula. Bake for 40 to 45 minutes, until the edges look golden-edged and a toothpick inserted in the center comes out with just a crumb or two.
As soon as the cake comes out of the oven, run a knife around the edges. Let it rest for only 4 to 5 minutes, then invert onto a serving platter right away. If any banana slices stick to the pan, gently lift and press them back into place.

PRO TIPS & VARIATIONS
- Use very ripe bananas with brown-speckled skin. They slice more cleanly, caramelize better, and bring a sweeter, more concentrated banana flavor.
- Flip the cake within 5 minutes of coming out of the oven. The longer the caramel sits in the pan, the more it cools and sticks.
- For a grown-up twist, add 1 tablespoon of rum to the brown sugar layer before placing the bananas, a technique used in classic French-style upside-down cakes.
- Swap buttermilk for plain Greek yogurt, thinned with a splash of milk, if buttermilk is unavailable.
- Dairy-free variation: Use melted coconut oil in place of butter for the topping and swap the buttermilk for full-fat coconut milk with a teaspoon of apple cider vinegar.
SERVING SUGGESTIONS
- Serve warm with a dollop of lightly whipped cream for a contrast of cool and soft.
- Add a scoop of vanilla ice cream to each plate so it melts slightly into the warm caramel glaze.
- Dust the top with a little powdered sugar and serve it at brunch beside coffee or chai tea.
STORAGE & REHEATING
- Fridge: Cover the cake and refrigerate for up to 3 days. The caramel topping stays intact and the crumb stays moist.
- Freezer: Slice and freeze individual pieces wrapped tightly in plastic wrap and foil for up to 2 months. Thaw overnight in the fridge.
- Reheat: Warm individual slices in the microwave for 20 to 30 seconds until the caramel turns glossy and the crumb softens, or place in a 300°F oven for 8 to 10 minutes.
FAQ SECTION
Q: Why does my banana upside down cake stick to the pan?
A: The most common reason is waiting too long before flipping the cake. The caramelized brown sugar cools and hardens fast, so invert the cake within 4 to 5 minutes of pulling it from the oven. Running a knife around the edge right away also helps release it cleanly.
Q: Can I use a springform pan for banana upside down cake?
A: Yes, but place foil underneath or set it on a sheet tray because the butter and sugar mixture can seep through the bottom. A standard 9-inch round pan with high sides is the most reliable choice for this easy banana cake.
Q: What type of bananas are best for banana upside down cake?
A: Ripe bananas with yellow skin speckled with brown are best. They are sweeter, softer after baking, and caramelize more evenly in the brown sugar glaze. Underripe bananas will taste starchy and will not deliver that melt-in-your-mouth layer.
Q: Can I make banana upside down cake ahead of time?
A: Yes. You can bake it a day ahead and reheat slices gently before serving so the caramel top turns glossy and warm again. The cake also keeps well covered in the fridge for up to 3 days without losing its moist crumb.
Q: Can I add other fruit to banana upside down cake?
A: Yes. Some versions layer in sliced pineapple, mango, or thinly sliced peaches alongside the bananas for a tropical twist. Keep the fruit in a single, tightly packed layer so the caramel coats everything evenly during baking.

Banana Upside Down Cake
Ingredients
Caramel Topping
- 4 tablespoons unsalted butter
- 1/2 cup packed brown sugar
- 3 to 4 medium ripe bananas, sliced lengthwise
Cake Batter
- 1 1/2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon ground cinnamon
- 3/4 teaspoon salt
- 1/2 cup vegetable oil
- 3/4 cup granulated sugar
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk
Instructions
- Preheat and prep the pan (3 minutes): Preheat the oven to 350°F (175°C). Spray a 9-inch round baking pan with nonstick spray and set it on a sheet tray to catch any drips during baking.
- Make the caramel base (2 minutes): In a small saucepan over medium heat, melt the butter and brown sugar together until liquified and slightly glossy, about 2 minutes. Pour the mixture evenly into the prepared pan. Do not overcook the caramel on the stovetop — it will deepen further in the oven as the cake bakes.
- Arrange the bananas (3 minutes): Peel the bananas and slice them lengthwise. Arrange them flat-side down over the brown sugar layer in a single, tight layer to cover the base.
- Mix the dry ingredients (2 minutes): In a medium bowl, whisk together the flour, baking powder, cinnamon, and salt until evenly combined.
- Make the batter (3 minutes): In a large bowl, whisk together the oil, granulated sugar, eggs, vanilla, and buttermilk until smooth. Add the dry ingredients and stir just until combined. Do not overmix — a few small lumps in the batter are fine and keep the cake more tender once baked.
- Bake (40–45 minutes): Pour the batter over the bananas and smooth the top with an offset spatula. Bake for 40 to 45 minutes, until the edges look golden and a toothpick inserted in the center comes out with just a crumb or two.
- Invert and serve (5 minutes): As soon as the cake comes out of the oven, run a knife around the edges to loosen it. Let it rest for only 4 to 5 minutes, then invert immediately onto a serving platter. If any banana slices stick to the pan, gently lift and press them back into place.
