Fork and Spoon Icon

Whenever I have ripe bananas, I look for a new banana bread recipe to try. I finally found my favorite! This is, without a doubt, the BEST banana bread/cake recipe I have ever baked! The sugar topping is an unbelievable surprise! This is now my go to banana recipe!

The secret to this “banana bread” is that it’s baked in a 9-inch square pan, and sprinkled with sugar before baking, which gives it that amazing, crunchy topping you see. 

Which, if you ask me, kind of transforms it from bread to cake. But the kind of cake that it’s okay to eat for breakfast, or a late-night snack, if you know what I mean.

Seriously though, that sugar topping! I don’t know where that’s been all my life. I’ll be sprinkling sugar on every banana flavored bread or cake I make from here on out.

To say my family loved this would be a huge understatement. If I would have had enough bananas, I would have gladly doubled the recipe. This stuff disappeared within in a day.

And as soon as it was gone, I wanted to make it again. Alas, it really does need to be made with very ripe bananas, so I had to wait several days for my newly purchased bananas to ripen.

No matter what kind of pan you bake this banana bread in, the sugar topping is an absolute must!

I hope you love this simple (yet utterly amazing) banana treat as much as we did.  Really, just make this Banana Bread Snack Cake. You won’t be sorry, and you can thank me later.

Recipe Tips

  • The key to intense banana flavor is super ripe bananas! Look for bananas that are heavily speckled or nearly black—they’re the sweetest and mash up beautifully. If you’re in a hurry and don’t have ripe bananas, pop them in the oven at 300°F for 15-20 minutes until the skins turn dark. Let them cool before mashing.
  • Feel free to stir in chopped pecans, walnuts, or even chocolate chips. It’s also great with a dollop of whipped cream or a drizzle of caramel sauce on top.
  • I know it’s hard to wait, but allowing the cake to cool slightly helps it set and makes cutting into neat squares a breeze. Use a serrated knife for the cleanest cuts.

Be sure to save this recipe to your favorite Pinterest board for later.

FAQ Section Icon

FAQs

How many cups of mashed banana are in this recipe?

You’ll need roughly 1 1/2 – 2 cups of mashed banana for this recipe. More banana will make a more moist cake.

Can I double this recipe?

Yes, if you have enough ripe bananas! In fact, I highly recommend doubling this recipe and baking it in a 9×13 pan.

What if I don’t have a 9-inch square pan?

A 9-inch round cake pan will work too. Just cut the cake into wedges. If you use an 8-inch pan, you may need to add a few minutes to the cooking time.

Can I use frozen bananas?

Frozen bananas work wonderfully in this recipe. Let them thaw completely, then drain any excess liquid before mashing. They’re often even sweeter after freezing, so it’s a great way to use up bananas you’ve saved for baking.

    I have this baking in the oven right now. Husband LOVES banana bread, with walnuts! It was so easy to mix up. I had a 6th banana. The first 5 were frozen, and the last one was hanging on the banana tree. I reasoned they were all small bananas, so the last one got thrown in too. I sprinkled some sugar cinnamon that I always have on hand, over the top of batter.
    There is only 2 of us here, but I know 1/4 of this will be gone by tonight…

    So so good!!! I just made this an hour ago – here were my tweaks, some taken by liberty, others because I didn’t have certain things:
    I only had a large circular glass pie dish (too lazy to measure dimensions but looks like a 10”w x 4”deep) so I greased that with butter and baked in that. I used 5 overripe bananas that I had frozen, mashed them up for the batter. I browned the (unsalted for me) butter on the stovetop and allowed to cool to add an extra dimension of richness, and also added about a tsp of light miso paste for nutty salty yumminess into the wet batter. For the brown sugar I was low on all sugars but I did half and half light brown and dark brown sugar. Into the dry I added a little nutmeg and cinnamon to my preference. I also only had bread flour so I used that. I didn’t have any nuts so didn’t add. And for the sugar topping I ran out of white sugar so I only had enough for about half white and the remaining was light brown sugar, mixed those together with a pinch of salt and sprinkled over top. Finished baking in my oven a little longer at 55 mins. If I were to serve this as a dessert to guests or family it’d be so good with a caramel of some kind
