When the urge for an easy decadent dessert hits, this Chocolate Banana Cake is perfect for a quick and easy treat.  It won’t last for long because everyone will want to have a second slice!

I absolutely love bananas in baking including banana bread, banana cake and my absolute favorite chocolate chip banana bread!

While I do love a good Chocolate Cake From Scratch, sometimes I just want to get something put together quickly and easily.  This chocolate banana cake fits the bill perfectly!

This recipe starts with a boxed chocolate cake mix and once mixed, the ripe mashed bananas and chocolate chips are mixed in. If your banana peels have little brown flecks, they are ripe and ready to use! While this cake does have 3 bananas added, they don’t add a ton of banana flavor to the mixture but what they do add is tons of moisture making this cake taste decadent and homemade. (In fact there are lots of great ways to make a box cake mix taste homemade!

I love to use either my One Minute Easy Chocolate Frosting a good Chocolate Buttercream Frosting to top this (or even store bought if you prefer).  If you don’t have chocolate frosting on hand, whipped cream or whipped topping is great too!

This cake will stay moist for days (although it never lasts that long around here) but it also freezes very well if you’d like to make it ahead of time.  Simply prepare as directed, cool completely and then cover well and freeze.

This really is a deliciously moist cake that requires very few ingredients.  For a fun and easy twist, you can use any flavor cake mix in this recipe with great results including yellow cake or spice cake with chopped nuts in place of the chocolate chips (and top it with homemade Cream Cheese Frosting).  The possibilities with the basic recipe are endless.

  1. Just took this out of the oven. It smells amazing!! I have a banana icing, that will be going on top of it for extra flavor. 5 stars

    1. Hi Jasmine, I haven’t tried this in a bundt pan however, it is a very soft cake so I’m not sure how would work.

  2. Followed recipe exactly and the cake came out so decadent! Moist/delicious/
    Family loved it thanks for the recipe! Won’t be making banana bread as often now that we have yummy options5 stars

  3. I tried your banana cake recipe and it was awesome.
    I want to try this one too.
    may i know how many ml or cups equivalent of cake flour for 1 box of cake mix?5 stars

    1. Cake mix has other ingredients besides flour so switching for just flour will not work. The box cake mix is approximately 15.25 oz/432g.
