Recipe Overview

Prep Time: 15 minutes
Cook Time: 45-50 minutes
Total Time: 60-65 minutes
Servings: 12
Yield: 1 9-inch square cake
Dietary Type: Vegetarian

Ingredients

2 cups flour
1 cup sugar
2 tablespoons unsweetened cocoa powder
1 teaspoon baking soda
½ teaspoon salt
¾ cup milk
½ cup mashed ripe banana (about 1 large or 2 small bananas)
⅓ cup butter, melted
1 tablespoon lemon juice
1 teaspoon vanilla extract
¾ cup mini chocolate chips or regular chocolate chips

Equipment Needed

9-inch square cake pan
Mixing bowls
Fork
Measuring cups and spoons
Oven
Toothpick
Cooling rack

Instructions

Preheat your oven to 350°F (175°C). While the oven heats, grease a 9-inch square cake pan thoroughly. This will prevent the cake from sticking and ensure easy removal.
In a large mixing bowl, whisk together the dry ingredients: 2 cups flour, 1 cup sugar, 2 tablespoons unsweetened cocoa powder, 1 teaspoon baking soda, and ½ teaspoon salt. Make sure to thoroughly combine these ingredients to evenly distribute the baking soda and cocoa powder. This will ensure a consistent rise and flavor throughout the cake.
Create a well in the center of the dry ingredients. This will allow you to easily incorporate the wet ingredients without creating lumps.
In the well, add the wet ingredients: ¾ cup milk, ½ cup mashed ripe banana, ⅓ cup melted butter, 1 tablespoon lemon juice, and 1 teaspoon vanilla extract.
Using a fork, beat the wet and dry ingredients together until well blended. This should take approximately 2 minutes. Avoid overmixing, as this can lead to a tough cake. The batter should be smooth with no large lumps. A few small lumps are okay.
Stir in ¾ cup mini chocolate chips (or regular chocolate chips) into the batter. Distribute them evenly throughout.
Pour the batter into the prepared (greased) 9-inch square cake pan. Spread it evenly to ensure even baking.
Bake in the preheated 350°F (175°C) oven for 45-50 minutes, or until a toothpick inserted into the center of the cake comes out clean. Start checking for doneness around 45 minutes. If the toothpick comes out with wet batter, continue baking for a few more minutes and check again.
Cool the cake completely in the pan on a wire rack before cutting it into squares. This will prevent the cake from crumbling and make it easier to handle.

Expert Tips & Tricks

Banana Boost: The riper the banana, the more intense the banana flavor. For an extra boost of banana flavor, use bananas that are very ripe, almost to the point of being overly ripe.
Chocolate Intensity: Adjust the amount of cocoa powder to control the intensity of the chocolate flavor. For a richer, darker chocolate flavor, use Dutch-processed cocoa powder.
Buttermilk Substitute: If you don’t have milk on hand, you can use buttermilk for a tangier flavor.
Doneness Check: If the top of the cake starts to brown too quickly during baking, tent it loosely with aluminum foil to prevent it from burning.
Melted Butter Tip: Make sure the melted butter is not too hot when you add it to the other ingredients, as it could cook the eggs slightly. Let it cool for a minute or two before adding.
Pan Prep: For guaranteed release, grease the pan and then lightly dust it with cocoa powder instead of flour. This prevents any white flour residue on the baked cake.

Serving & Storage Suggestions

This Double Chocolate Banana Snack Cake is delicious served at room temperature. You can dust it with powdered sugar for a more elegant presentation. It pairs perfectly with a glass of cold milk, a scoop of vanilla ice cream, or a warm cup of coffee.

To store, wrap the cake tightly in plastic wrap or place it in an airtight container. It will keep at room temperature for up to 3 days, in the refrigerator for up to 5 days, or in the freezer for up to 2 months. To reheat, thaw the cake in the refrigerator overnight and then warm it in a low oven or microwave until heated through.

FAQs (Frequently Asked Questions)

Q: Can I use frozen bananas for this recipe?
A: Yes, frozen bananas work perfectly well. Just be sure to thaw them completely and drain any excess liquid before mashing.

Q: Can I use oil instead of butter?
A: Yes, you can substitute the melted butter with a neutral-flavored oil like canola or vegetable oil. The texture of the cake might be slightly different, but the flavor will still be delicious.

Q: How do I prevent the chocolate chips from sinking to the bottom of the cake?
A: Toss the chocolate chips with a tablespoon of flour before adding them to the batter. This will help them stay suspended throughout the cake.

Q: Can I make this recipe in a different size pan?
A: Yes, you can use an 8-inch square pan, but the baking time may need to be adjusted. Start checking for doneness a few minutes earlier.

Q: My cake came out dry. What did I do wrong?
A: Overbaking is the most common cause of a dry cake. Be sure to check for doneness with a toothpick, and remove the cake from the oven as soon as the toothpick comes out clean. Also, make sure you are measuring the flour correctly; spooning it into the measuring cup instead of scooping directly from the bag.
