The Best Banana Cake Recipe

Why This Banana Cake Really Works:

• Bananas are for more than just flavor. Overripe bananas aren’t just essential for locking in classic banana flavor. They’re also full of natural sugars and pectin, which help lock in moisture and create a plush, super moist crumb that stays soft for days.
• Butter for flavor, oil for texture. This is a combo that I use in many of my cakes (both my vanilla cake and chocolate cake recipe feature a blend of the two). While butter adds incredible flavor, butter alone can dry out a cake crumb a bit, especially one that needs to be refrigerated (since butter solidifies in the fridge it can make cakes seem dense and dry). Cooking oil is great for adding moisture, but doesn’t lend the same rich, buttery flavor. By using a blend of both, we get incredible flavor and texture.
• Cream cheese frosting, balanced just right. The tangy element of it works especially well here to counter the sweet, banana-rich base. A little acidity balances the whole bite, so it doesn’t feel too heavy! Psst: If you want to make this cake over-the-top luxurious, try it with my cream cheese-based brown butter frosting!)

Ingredients:

My banana cake recipe was carefully and intentionally designed to be sweet, simple, super flavorful, and moist. When developing it, I largely drew from my pumpkin cake (of all things). Let’s talk about a few of the key players:

• Bananas. For the best flavor & moistest cake, you should use overripe, spotty or mostly brown bananas. Have some that are looking a little sad on your counter and starting to attract fruit flies? Grab those. King Arthur has a great guide on choosing the best bananas to use for baking. A banana cake made with underripe or even regularly ripe bananas could be a bit less sweet, more dry, and underwhelming in flavor.
• Butter AND oil. Those of you who have made my Funfetti cake or marble cake recipe know that a blend of the two yields a better cake than simply using all butter or all oil. For my banana cake recipe I sought balance, and a blend of the two yielded a perfect moist cake. For the oil, any neutral cooking oil (canola or vegetable are most common) will work.
• Sugar. Another best-of-both-worlds scenario. Granulated sugar adds sweetness without weighing the cake down too much, while brown sugar adds a depth of flavor that pairs nicely with the bananas (thanks to the molasses in brown sugar!).
• Leavening Agents. Baking powder and baking soda create a perfect rise. The baking soda reacts with the banana and buttermilk (and helps create that beautiful golden surface), while the baking powder ensures a reliably even lift across the cake. Without the two of them we’d have a dense, gummy cake.
• Buttermilk. While this plays a role in helping the banana cake to rise a bit when combined with the baking soda, perhaps more importantly it adds moisture and a wonderful depth of flavor.

As always, this is just an overview of a few of the main ingredients I used and why. For the full recipe please scroll down to the bottom of the post!

How to Make Banana Cake

Make the cake batter & bake

Start by mashing your bananas really well (a fork or potato masher works great). Set these aside and cream together your butter and sugars and gradually incorporate the rest of your wet ingredients.

The dry ingredients should be whisked together in a separate bowl, then gently stirred into the wet ingredients. Do not use your electric mixer for this step. Instead use a spatula to gently fold things together until the batter is completely combined. Overdoing it can cause the cake crumb to be dense and dry (don’t under-do it either, though, or the cake could sink or not bake properly).

ake the cake until it’s golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs. If you notice your cake is darkening more than you’d like in the oven, you can tent it with foil to prevent this.

SAM’S TIP: Measure your bananas! The recipe lists the amount of mashed bananas that you need for a reason, simply stating “3 bananas” or “4 bananas” is too ambiguous and could lead to a cake that’s too dry and bland (if under-measured) OR too moist and sinks in on itself (if over-measured). It’s best to mash and measure (or go by weight!).

Make the Cream Cheese Frosting

SAM’S TIP: The pan you bake your cake in matters. The banana cake will take longer to bake in a glass pan than a metal one.

The frosting is quick and easy to prepare. Beat softened cream cheese and butter, vanilla, and salt until smooth and creamy (make sure there are no lumps!), then gradually stir in the powdered sugar. Stirring in a bit of cream gives you a silky smooth frosting that spreads easily (similar to the one I use on my zucchini cake).

Top with regular or toasted pecans or walnuts (my preference), or make things extra decadent with a drizzle of caramel sauce or dulce de leche for a finishing touch!
