There is something so satisfying about turning a few overripe bananas into a recipe everyone gets excited about. And while banana bread will always have its place, this banana snack cake feels a little more fun, a little more bakery-style, and honestly even easier to slice, serve, and snack on throughout the week.

This cake is soft, moist, packed with banana flavor, and topped with a buttery cinnamon crumble that takes it over the top. I love it as an afternoon snack with coffee, packed in lunches, or warmed up for dessert. If you have three ripe bananas sitting on the counter, this is the recipe to make next.

Main Ingredient Breakdown

Bananas

The star of the recipe. Very ripe bananas bring natural sweetness, moisture, and the best banana flavor.

Greek Yogurt

Adds richness and moisture while keeping the cake tender. Sour cream also works well.

Chocolate Chips

Mini chocolate chips give you chocolate in every bite without overpowering the banana flavor.

Crumble Topping

A simple mix that bakes into a sweet buttery layer with the perfect little crunch.

Instructions

1. Preheat your oven to 350°F. Grease and line an 8×8 baking pan with parchment paper.
2. In a small bowl, combine the crumble topping ingredients until sandy clumps form. Set aside.
3. In a large bowl, whisk together the mashed bananas, eggs, Greek yogurt, melted butter, brown sugar, granulated sugar, and vanilla until smooth.
4. Add the flour, baking soda, baking powder, salt, and cinnamon. Stir until just combined. Do not overmix.
5. Fold in the mini chocolate chips.
6. Spread the batter into the prepared pan. Sprinkle the crumble topping evenly over the top.
7. Bake for 35 to 45 minutes, or until the center is set and a toothpick inserted comes out mostly clean.
8. Let cool before slicing and serving.

Tips for the Best Banana Snack Cake

• Use bananas with lots of brown spots for the sweetest flavor.
• Do not overmix the batter or the cake can become dense.
• Tent loosely with foil near the end if the top browns too quickly.
• Let it cool before slicing so the texture sets properly.
• Warm leftovers for 10 seconds in the microwave for an extra cozy treat.
