What Goes Into This Recipe – Ingredients
- For the topping:
- 4 tablespoons unsalted butter
- 1/2 cup packed light or dark brown sugar
- 4–5 ripe bananas, sliced lengthwise or into rounds
- Pinch of flaky salt (optional, but wow)
- For the cake batter:
- 1 1/4 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine salt
- 1/2 cup granulated sugar
- 1/4 cup packed brown sugar
- 1/3 cup neutral oil (canola or vegetable)
- 2 large eggs, room temp
- 1/2 cup sour cream or full-fat Greek yogurt
- 1/3 cup whole milk
- 1 1/2 teaspoons pure vanilla extract
- 1/2 teaspoon ground cinnamon (optional but recommended)
- Zest of 1/2 orange or 1/2 lemon (optional brightness)
The Method – Instructions
- Prep the pan: Heat oven to 350°F (175°C).
Grease a 9-inch round cake pan (2 inches deep) or a 9-inch square pan. Line the bottom with parchment.
- Make the caramel base: Melt 4 tablespoons butter in a small saucepan. Stir in 1/2 cup brown sugar until glossy and bubbling, 1–2 minutes.
Pour into prepared pan and tilt to coat evenly. Sprinkle a pinch of flaky salt, if using.
- Arrange bananas: Lay banana slices over the caramel in a tight pattern—overlap slightly for that bakery look. Set aside.
- Dry ingredients: In a bowl, whisk flour, baking powder, baking soda, salt, and cinnamon.
- Wet ingredients: In another bowl, whisk sugars, oil, eggs, sour cream, milk, vanilla, and citrus zest until smooth.
- Combine: Add dry to wet and stir gently until just combined.
Batter should be smooth but not overmixed. No marathon whisking.
- Fill the pan: Pour batter over bananas and level the top.
- Bake: 35–42 minutes, until the center springs back and a toothpick comes out with a few moist crumbs.
- Cool briefly: Let rest 10 minutes on a rack. Loosen edges with a knife.
- The flip: Place a serving plate over the pan and invert confidently.
Tap to release. Peel off parchment. Bask in applause.
- Serve: Slice warm.
Add vanilla ice cream, whipped cream, or a drizzle of warm caramel if you’re feeling extra (you are).
How to Store
- Room temp: Cover and keep up to 2 days. The caramel keeps it moist.
- Fridge: Up to 5 days; warm slices in the microwave 15–20 seconds for best texture.
- Freeze: Wrap individual slices tightly and freeze up to 2 months. Thaw overnight in the fridge, then warm before serving.
Nutritional Perks
- Bananas: Potassium, vitamin B6, and fiber—your dessert doing a tiny bit of good.
- Moderate sugar: Sweet, but not face-melting.
Balanced with dairy fat for better satisfaction.
- Protein boost: Eggs and yogurt add structure and satiety. It’s dessert, not a protein bar—just setting expectations.
What Not to Do
- Don’t overmix the batter. Tough cake = sad cake.
- Don’t use a shallow pan. Caramel bubble-over is a mess and a smoke alarm special.
- Don’t wait too long to flip. After 10–15 minutes, the caramel sets and sticks like glue.
- Don’t skip parchment. Insurance policy for a clean release. FYI, future you will thank you.
Variations You Can Try
- Banana Foster Vibes: Add 1 tablespoon dark rum to the caramel and a pinch of nutmeg.
- Nut crunch: Scatter 1/2 cup chopped pecans or walnuts over the caramel before the bananas.
- Chocolate twist: Fold 1/2 cup mini chocolate chips into the batter, or drizzle melted dark chocolate after flipping.
- Gluten-free: Use a 1:1 gluten-free flour blend with xanthan gum.
Bake time may vary by a few minutes.
- Dairy-free: Swap plant-based butter, non-dairy yogurt, and almond milk. Use neutral oil as written.
FAQ
Can I use frozen bananas?
Yes, but thaw and drain them well first. Frozen bananas release extra moisture, which can dilute the caramel layer if you skip draining.
Do I need a cast-iron skillet?
No.
A standard 9-inch cake pan works perfectly. If using cast iron, make the caramel directly in it and proceed as usual.
How ripe should the bananas be?
Speckled and fragrant is ideal. Fully black peel bananas are great for banana bread, but here they can get too mushy under heat.
My caramel crystallized—what happened?
Likely over-stirring after it started bubbling or heating too long.
Keep it brief—just melt, mix, and pour. A teaspoon of corn syrup can help prevent crystallization, IMO.
Can I double the recipe?
Yes. Use a 9×13-inch pan and extend baking time to 40–48 minutes.
Watch for the same visual cues.
My Take
This Banana Upside Down Cake hits that sweet spot between “effortless” and “looks expensive.” The caramelized top sells it, but the tender, lightly spiced crumb keeps you coming back. It’s the dessert I make when I need guaranteed compliments without babysitting a mixer. One flip, instant hero status—no apology tour necessary.
