Banana bread cake is the best way to use up ripe bananas when you want something a little more special than a standard loaf. This cake has a sticky caramelized banana topping that turns the humble banana bread flavor into a truly decadent dessert. The first time I served this after a Sunday dinner, everyone called it banana bread’s fancier cousin and there were no leftovers.
I was surprised how much my kids loved this even though it looks so different from their usual banana muffins and now it is the most requested way to use those spotty bananas.
Ingredients
- Unsalted butter: gives the topping a rich buttery flavor choose a good quality butter for the best caramel
- Light brown sugar: makes the topping deeply sweet and sticky you want it tightly packed for accurate measuring
- Ripe bananas: sliced thick for the topping and mashed for the cake overripe bananas are great for both jobs
- Large egg: binds the batter and gives structure use fresh eggs for best lift
- Granulated sugar: adds a crisp sweetness and balances the brown sugar’s warmth
- Canola or vegetable oil: keeps the crumb super tender coconut oil works in a pinch but has a bit of flavor
- Sour cream: adds moisture and tang full fat or lite both work or use Greek yogurt for an added protein boost
- Vanilla extract: rounds out all the flavors go with pure vanilla if you can for the cleanest taste
- All purpose flour: gives the cake its soft texture sift it if you want extra fluffiness
- Baking powder and baking soda: help the cake rise and stay light make sure they are still active
- Salt: sharpens the sweetness and keeps the flavor balanced use fine sea salt if possible
Step-by-Step Instructions
- Prepare the Pan:
- Line your baking pan with heavy duty foil then spray with cooking spray to prevent any sticking. The foil helps you lift the cake out easily after it has cooled. Set the pan aside while you prep the layers.
- Make the Caramel Banana Topping:
- In a large saucepan melt the butter with the brown sugar over medium heat. Stir almost constantly using a whisk or spatula until the sugar dissolves into the melted butter and everything looks smooth. Let it boil gently for about thirty to forty five seconds so it thickens just a bit then immediately pour this sauce into your lined pan. Lay the sliced bananas on top of the caramel in a single even layer with just a little space between the pieces. They will shrink and melt into the sauce so do not slice too thin. Set aside.
- Mix the Cake Batter:
- In a large bowl whisk together the egg both sugars oil sour cream and vanilla until smooth. Add the mashed bananas and mix until evenly combined. Sprinkle the flour baking powder baking soda and salt over the mixture then gently fold everything together with a spatula just until you see no more dry spots. Do not overmix or the cake could turn dense.
- Assemble and Bake:
- Carefully pour the batter over the bananas in the pan smoothing the top with a spatula. Bake at three hundred fifty degrees Fahrenheit for about forty two to forty five minutes. The cake should be golden brown set in the center and a toothpick inserted comes out clean or with just a few moist crumbs.
- Cool and Invert the Cake:
- Let the cake cool in the pan on a wire rack for at least three hours. For best results you can leave it to cool overnight. When completely cool use the foil overhang to help lift the cake out then place a board or platter on top and invert so the bananas are facing up. Peel away the foil gently and cut into pieces.

Bananas are one of my favorite baking ingredients because they act as a natural sweetener and keeper of moisture. I remember my grandmother would always save the darkest bananas for her cakes because she said that is where all the flavor lives.
Storage Tips
Store leftovers covered at room temperature for up to one week. If it is warm in your kitchen you can refrigerate the cake but bring slices up to room temperature before eating to keep the texture soft. Wrap the cake in foil or keep it in an airtight container to prevent it from drying out.
Ingredient Substitutions
If you do not have sour cream Greek yogurt works perfectly and keeps the cake extra moist. Coconut oil can switch in for vegetable oil but it will add a light coconut flavor to the cake. Only have dark brown sugar Use it instead of light brown for a deeper molasses note. For a gluten free version use your favorite measure for measure gluten free flour blend.
Serving Suggestions
This cake is delicious on its own but becomes truly special with a spoonful of whipped cream or a scoop of vanilla ice cream. Serve it warm or room temperature. For a brunch treat cut into small squares and serve with coffee. It lends itself to celebrations and casual gatherings alike.

The History of Banana Bread Cake
Banana bread became popular in the United States during the Great Depression when home cooks found ways to use up overripe fruit. This banana bread cake builds on that tradition but with a modern dessert spin inspired by southern upside down cakes. The caramelized banana top is what really makes it shine turning pantry basics into a showstopper.
