Banana Crumb Cake is the cozy bake to make when you and I want banana bread flavor with the tender, cake‑like crumb and crunchy streusel of a coffee cake. A moist banana‑sour cream cake base gets topped with a buttery cinnamon crumb that bakes into a sweet, golden layer perfect with coffee or as an anytime dessert.
Why you’ll love this Banana Crumb Cake
This cake uses simple pantry staples and overripe bananas to create a moist, tender crumb that stays soft for days thanks to sour cream and butter. The cinnamon‑brown sugar crumb topping adds sweetness and texture without needing frosting, making it easy to slice and serve straight from the pan.
It works equally well as a breakfast or brunch cake, afternoon snack, or dessert with a scoop of ice cream. The recipe fits a standard 9‑inch pan and bakes up in under an hour, so it’s ideal whenever you have a few bananas on the counter that need to be used.
