Chocolate Banana Snack Cake
This Chocolate Banana Snack Cake is the perfect mix of chocolate and bananas—one of my favorite combos! The banana cake is soft, moist, and full of flavor, delicious even on its own, but the rich chocolate swirl makes every bite even better!

Ingredients
Banana Cake
- ½ cup (1 stick / 113 g) unsalted butter, melted
- 3 ripe bananas, mashed (about 1 cup)
- ¾ cup (150 g) granulated sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- ½ cup (115 g) sour cream
- 1 ½ cups (187.5 g) all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon kosher salt
Chocolate Swirl
- ½ cup (84 g) semi-sweet chocolate chips
- ¼ cup (½ stick / 57 g) unsalted butter
- 2 tablespoons regular unsweetened cocoa powder
Instructions
Banana Cake
- Preheat oven to 350°F (175°C). Line a 9x9-inch baking dish with parchment paper, leaving an overhang for easy removal. Set aside.
- In a large bowl, whisk together melted butter, mashed bananas, sugar, egg, vanilla extract, and sour cream until smooth.
- In a separate bowl, whisk together flour, baking soda, and salt. Add the dry ingredients to the wet mixture and stir until just combined. Do not overmix.
Chocolate Swirl
- In a microwave-safe bowl, combine the chocolate chips and butter. Microwave in 20-second intervals, stirring after each, until smooth.
- Stir in the cocoa powder until fully incorporated.
Assembly
- In a small bowl, reserve ½ cup of the banana batter and set it aside. Then, pour the remaining batter into the lined baking dish.
- Gently fold the chocolate mixture into the reserved banana batter. Dollop the chocolate batter onto the banana batter in the pan. Use a knife to swirl it into the banana batter, being careful not to overmix.
- Bake for 30-35 minutes, or until a toothpick inserted into the center of the cake (avoiding the chocolate swirl) comes out with a few moist crumbs but no wet batter.
- Let the cake cool in the pan for 10 minutes. Then, lift it out using the parchment paper overhang.
- Serve warm or at room temperature.
