Whole Wheat Peanut Butter Banana Snack Cake

Peanut Butter Banana Snack Cake – This banana cake recipe is so tender and delicious with the peanut butter, chocolate chips, and topped with Nutella!

I always tend to buy too many bananas at the store. I am rather picky on the condition they are in when I eat them, so they go from good to bad in what seems like minutes. So I am always trying new recipes to use them up!  This Blueberry Banana Bread is by far the most popular at my house and with you guys!  

There are so many ways to use up over ripe bananas, but is there really any better way that cake?! This might be the best banana cake recipe I have ever tried.  I used whole wheat flour, to try it make it just a little bit better for you, but you would never know!  The chocolate chips and extra chocolate on top make it decadent and delicious. But you could definitely skip them if you aren’t a chocolate fan. You can never go wrong with chocolate and banana together though – Banana Pancakes with chocolate chips are a weekend staple. 

What You’ll Need

  • Bananas
  • Egg
  • Oil – you can use vegetable oil, canola oil or avocado oil. Any neutral flavor oil works great.
  • Creamy Peanut Butter
  • Vanilla Extract
  • White Whole Wheat Flour – you can also just use all-purpose flour
  • Granulated Sugar
  • Baking Soda
  • Cinnamon
  • Mini Chocolate Chips

How to Make Banana Cake

  • This cake doesn’t require a mixer!  So you start by mashing your bananas in a bowl until they are nice and smooth. 
  • Mix in the peanut butter, oil and vanilla.  You can just use a spatula or even a whisk to get this nice and smooth.  
  • Add the flour, sugar, baking soda, salt and cinnamon to the mix. You want to be careful not to over mix or your cake can come out tough.  So just until the flour is mixed in and then stop. 
  • Add in your chocolate!  You can leave out the chocolate chips if you want, but why would you?  Just gently fold them in to the dough.  
  • Pour into a prepared pan and bake. You want to let it cool completely before you put on any frosting or chocolate or it will just melt.

How To Store Leftovers

This banana cake will last on the counter for 3-4 days. It is a great dessert or treat to have with your coffee or tea in the afternoon.  Just cover with plastic wrap or foil and it should last a few days for you to enjoy. 

Banana cake is similar in flavor to banana bread, but it is definitely different. This banana cake recipe has the texture of a cake, not the quick bread that you think of.  It is more tender and not quite as dense.  You can free it similar to you would banana bread though.  So if you want to have a few slices stashed in your freezer you can!  

Tips to Freeze Banana Cake

  • If you want to freeze the whole cake you can leave it in the pan and just double wrap in foil to make sure it stays fresh. 
  • To freezer just a few slices, wrap each slice in plastic wrap and then either place in a freezer safe bag or wrap in foil. You want to make sure it lasts and does not get freezer burn.

How To Serve Banana Cake

How you top your cake is totally up to you!  I like to drizzle just a little bit of Nutella over the top, but you could use your favorite chocolate frosting or even just leave it as is.  There is chocolate chips in the cake, so if that is enough sweet for you, leave the frosting off.  

Your kids will love coming home to this banana snack cake. It is really easy to make too, so when you have a couple extra bananas on the counter you can whip it up in no time!

I'm not using peanut butter, I'm using cookie butter and some honey. I think it'll still taste good.
