Banana Bread Cake

Pro tips

• Whisk the dry and wet ingredients separately, then fold together gently—overmixing develops gluten and can toughen the crumb.
• Mash the banana thoroughly before mixing so it distributes evenly; lumps can result in uneven texture.
• Cool the cake completely on a wire rack before dusting with confectioners' sugar to prevent the sugar from melting or clumping.
• Test doneness at 30 minutes with a toothpick; every oven varies, and a few extra minutes can dry it out.

Substitutions

• All-purpose flour → whole wheat flour (use 1½ cups for slightly denser crumb and nuttier flavor)
• Brown sugar → granulated sugar (use 3/4 cup; cake will be less moist and less rich)
• Canola oil → melted butter or coconut oil (1:1 ratio; butter adds richer flavor)
• Confectioners' sugar → cinnamon-sugar mixture or cream cheese frosting (optional topping)

Storage & make-ahead

Store covered at room temperature for up to 2 days, or refrigerate for up to 5 days. Reheat gently in a 300°F oven if preferred.

Can I use overripe bananas for this recipe?

Yes. Very ripe (brown-spotted) bananas are ideal because they have more natural sweetness and blend more easily into the batter.

How do I know when the banana bread cake is done?

Insert a toothpick in the center of the cake. It should come out clean with no wet batter clinging to it. Baking takes 30 to 35 minutes at 350°F.

Can I make this recipe without canola oil?

Yes. Substitute with vegetable oil, melted butter, or coconut oil in a 1:1 ratio. Butter will yield a richer flavor.

How should I store leftover banana bread cake?

Cover and store at room temperature for up to 2 days, or refrigerate for up to 5 days. Reheat gently in a 300°F oven if desired.

Can I double this recipe?

Yes. Double all ingredients and bake in a 9×13-inch pan. Check for doneness at 35 minutes; it may take up to 40–45 minutes.
