Banana Crumb Cake

If you love bananas, I`m sure you`re not new to baking with them. I love eating them and I love baking with them, so I have many banana recipes. Luckily for me, my “little” cousin also LOVES bananas. Their family loves banana bread, so I`m constantly sharing new banana bread recipes with them to taste test.

It was my cousin`s birthday and he requested banana cake. At first, it was a brownie he wanted. Then, the day before his birthday party, he called me and decided he wanted a banana cake instead. I had to giggle inside my head. Kids! I love their thought process. Thinking to myself, I knew he was most likely referring to banana bread, not banana cake. Yet, I didn`t inquire any further. I mean, if he says cake, I`ll bake him a cake! Plus, I felt a cake was more birthday-worthy compared to a banana bread loaf.


This cake isn`t a fancy layer cake type, but it`s still a great cake! The banana flavor is totally there and it`s soft and sponge-y. The cake is about an inch or so. I thought it was perfect to give him because I knew his father (my uncle) had ordered a cake and a cheesecake for the party already. (As if he didn`t already have enough cake!) This was just an edible gift from me since I`m poor and didn`t buy him a present. HAHA.

For the sake of taking a blog photo for the cake, I had to cut out 3 square pieces. Yeah, I totally gave the cake to him in squares, like brownies. Hey, the kid was turning 10, so he didn`t care about presentation. It was the taste that matter and he told me it was good! So, yay for banana cake!

Give this recipe a go if you`re looking for a change from your typical banana bread recipes. As a cake, it`s sweeter and not as dense as a loaf. Try it yourself and see if a banana cake is your cup of tea.

Also, I felt like I used the words “love,” “banana,” and “cake” like a million times in just this post. Sorry. I just want you to eat some yummy banana cake with some crumble on top! 🙂
