Caramelized Banana Upside-Down Cake: From Prep to Plate

Step 1: Prepare Your Pan
Start by preheating your oven to 350°F (175°C). Grease your 9-inch round cake pan with a bit of unsalted butter to ensure easy release later.
Step 2: Create the Caramel Base
In a small saucepan over medium heat, melt the stick of unsalted butter and brown sugar together. Stir until smooth and bubbly, then remove from heat. Pour this caramel mixture into the prepared cake pan, spreading it evenly across the bottom.
Step 3: Arrange the Bananas
Slice your ripe bananas in half horizontally, then slice them vertically into 3 or 4 long pieces if they’re particularly large. Arrange the banana slices on top of the caramel mixture in the pan, creating a beautiful pattern.
Step 4: Mix the Cake Batter
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt. In another bowl, combine the egg, buttermilk, sour cream, oil, and vanilla extract. Mix until well combined.
Step 5: Combine the Ingredients
Pour the wet ingredients into the dry ingredients and gently fold until just combined. Be careful not to overmix; a few lumps are perfectly fine!
Step 6: Bake the Cake
Pour the cake batter over the arranged bananas in the pan. Bake in the preheated oven for about 30-35 minutes or until a toothpick inserted into the center comes out clean.
Step 7: Cool and Flip
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then, carefully invert the cake onto a serving plate, allowing the caramelized bananas to cascade beautifully on top.
Step 8: Drizzle with Caramel
If you desire, drizzle some salted caramel sauce over the top for an extra touch of decadence.
Season-by-Season Upgrades

- Spring: Add a sprinkle of chopped pecans or walnuts for a crunchy texture.
- Summer: Incorporate fresh berries like blueberries or strawberries for a burst of color and flavor.
- Fall: Mix in some ground cinnamon or nutmeg to complement the bananas.
- Winter: Serve warm with a scoop of vanilla ice cream on the side for a cozy dessert experience.
What Could Go Wrong
- Bananas Browning Too Much: Ensure your bananas are ripe but not overripe to avoid a mushy texture.
- Caramel Sticking: Grease the pan thoroughly to prevent sticking.
- Cake Not Rising: Check that your baking powder is fresh for proper leavening.
- Overmixing the Batter: This can lead to a dense cake; mix just until combined.
