Ingredients Checklist
Start with a quick rundown of what you’ll need to create this irresistibly moist and chocolatey banana snack cake.
-
1 cup (225g) very ripe banana, mashed (about 2 large bananas)
Adds natural sweetness, moisture, and rich banana flavor. -
½ cup (115g) unsalted butter, melted and cooled slightly
For tender crumb and flavor; coconut oil or neutral oil work for dairy-free. -
⅔ cup (135g) light brown sugar, packed
Deepens flavor and enhances moistness. -
2 large eggs, room temperature
Provide structure and stability. -
½ cup (120ml) whole milk or unsweetened almond milk
Contributes to the cake’s soft texture. -
1 teaspoon vanilla extract
Boosts the overall aroma and depth. -
1 ¼ cups (160g) all-purpose flour
For structure; can substitute up to ½ cup whole wheat flour for a heartier cake. -
¼ cup (25g) unsweetened cocoa powder (Dutch-process preferred)
For a rich, chocolatey base. -
1 teaspoon baking powder
Helps the cake rise evenly. -
¾ teaspoon baking soda
Activates with the banana’s acidity for lift. -
¼ teaspoon salt
Balances sweetness and enhances flavors. -
1 cup (170g) semisweet or dark chocolate chips, divided
Extra chocolate in every bite. -
½ teaspoon ground cinnamon (optional)
Adds a subtle warmth that pairs well with banana and chocolate. -
½ cup (60g) chopped walnuts or pecans (optional)
For added crunch and flavor.

Step-by-Step Instructions
Follow these detailed instructions for a foolproof and delicious Chocolate Banana Snack Cake every time.
-
Prep Pan and Oven:
Preheat oven to 350°F (175°C). Grease and line an 8-inch (20cm) square baking pan with parchment paper for easy removal. -
Mash Bananas:
In a large mixing bowl, mash bananas until smooth and lump-free. -
Mix Wet Ingredients:
Add melted butter, brown sugar, eggs, milk, and vanilla to the bananas. Whisk until fully combined and smooth. -
Add Dry Ingredients:
Sift in flour, cocoa powder, baking powder, baking soda, salt, and cinnamon if using. Gently fold the mixture together using a spatula until just combined—do not overmix. -
Add Chocolate and Nuts:
Fold in ¾ cup of chocolate chips and nuts if using, reserving the rest for the top. -
Pour and Top:
Spread the batter evenly into the prepared pan. Sprinkle the remaining chocolate chips over the surface. -
Bake:
Bake for 28–33 minutes, or until a toothpick inserted in the center comes out with moist crumbs (not wet batter).
For extra moistness, err on the side of slightly underbaked—banana cakes continue cooking as they cool. -
Cool:
Let the cake cool in the pan on a wire rack for 10–15 minutes. Then lift out using the parchment to cool completely. -
Slice and Serve:
Cut into squares and enjoy plain, dusted with powdered sugar, or frosted as desired.

Tips for Perfect Results
Use these essential tips to guarantee a moist, tender, and flavorful snack cake every time.
-
Banana Ripeness:
The riper and spottier your bananas, the sweeter and more flavorful your cake will be. -
Measuring Flour:
Spoon and level flour into your measuring cup to prevent a dense, dry cake. -
Do Not Overmix:
Stir the batter only until just combined to keep your cake light and tender. -
Pan Size:
For a thicker cake, use an 8-inch pan. A 9-inch pan works too but will yield a thinner cake—reduce baking time by a few minutes. -
Additions:
Mix in shredded coconut, a swirl of peanut butter, or use a mix of dark and white chocolate chips for variation. -
Egg-Free Option:
Substitute ¼ cup unsweetened applesauce or 2 flax “eggs” (2 tbsp ground flaxseed + 5 tbsp water, rested) for vegan/dairy-free needs. -
Test Early:
Begin checking for doneness at the 28-minute mark. Overbaking can dry out the cake. -
Storing:
Keep leftovers covered at room temperature for up to 3 days, or refrigerate for longer freshness.
Serving Suggestions
Make your Chocolate Banana Snack Cake even more special with creative serving ideas.
-
Warm with Ice Cream:
Serve squares slightly warmed with a scoop of vanilla or chocolate ice cream. -
Nutty Crunch:
Top with toasted chopped nuts or coconut flakes. -
Coffee or Tea:
Pair with coffee, espresso, or chai for a satisfying snack. -
Breakfast Treat:
Enjoy with Greek yogurt and fresh berries for a wholesome morning bite. -
Frosted:
Spread with chocolate ganache, peanut butter frosting, or cream cheese icing for dessert-worthy flair. -
Lunchbox Favorite:
Wrap individual slices for an on-the-go treat in school or work lunches.
