Banana cake is so satisfying, light fluffy, and full of banana flavor. Smothered in the most delicious brown butter frosting! This post may contain affiliate links. Read my disclosure policy here.
This cake is a great way to use up those overripe bananas. It comes out soft, moist, and delicious every time like my Spiced Rum Cake. Make sure to try My Starbucks Copycat Banana Bread the next time you have extra ripe bananas in the house.
What's the difference between banana bread and banana cake?
Banana cake is made with butter with the addition of mashed bananas. Banana bread is much denser and perfect to slice warm with a slab of butter.
Can I freeze ripened banana to use later?
Yes, just put the bananas in a large freezer bag and freeze them for up to 3 months. The peels will turn black in the freezer. Once the bananas are thawed they will contain more liquid once they are mashed. Totally fine they bake up beautifully in this recipe.
How to store leftovers
Store banana cake in an airtight container at room temp for 3 days or in the refrigerator for 1 week.
- When you measure your flour, spoon it into your measuring cup and then level off with a knife.
- Overripe bananas make the best banana cake.
- I used walnuts in this banana cake but pecans are also delicious or leave them out altogether.
Brown Butter Frosting is seriously so good you'll want to lick the pan! It's super easy to make you just need to do it quickly. The frosting spreads easiest when it's warm and poured on a warm cake. I always start my frosting just when the cake comes out of the oven.
