The Fall-Back Recipe

Do you have a fall-back recipe?

You know, one of those tried-and-true dishes you can always make in a pinch if you need it?

My fall-back recipes save the day! If I’m going to a potluck-type dinner and need to take something, or have friends stopping, by, or just need a quick fix for a weeknight meal, my fall-back recipes save the day!

Today’s Chunky Monkey Vegan Cake is no exception! If you’re into chocolate, banana, and peanut butter mixed all together, then you and me? We are two peas in a pod. Kindred Spirits!

You had a bad hair day, followed by traffic jams, incessant meetings, and general overall life gridlock?

And there’s nothing in the cupboards to make that day any better! Put the kibosh on that negative vibe. That’s right…fall-back recipe to the rescue!

But this can be more than a fall-back recipe. In fact, it’s so delicious, serve this as a chunky monkey birthday cake too!

We all need a recipe like this and today I’m going to share mine with you. It’s one of those recipes that you can make time after time and everybody loves it, or you can wait three months to make it and everyone loves it even more.

Personally, trying new recipes is a hoot, but it’s also important to have some oldies but goodies in the mix.

What is Chunky Monkey Cake?

A chunky monkey cake recipe includes peanut butter, chocolate, and bananas! It’s my favorite triple threat combination!

This cake is made with the kinds of ingredients that you almost always have around the house:

  • flour
  • sugar
  • bananas
  • peanut butter
  • chocolate chips
  • cocoa powder

It’s the simple ingredients that makes the Chunky Monkey Vegan Cake so easy to throw together for just about any reason. See? It’s my fall-back cake!

It’s a real crowd pleaser which means when I announce I’m making my chunky monkey vegan cake, the crowd goes wild. OK. Honestly, they might applaud a little, which may not be the true definition of wild, but there’s excitement in the air.

How to Make Chunky Monkey Cake

The vegan cake recipe is better than a banana cream snack cake if you ask me! And it’s pretty straight forward. Simple, mix together the wet ingredients:

  • peanut butter
  • vegetable oil
  • sugar
  • vanilla
  • mashed bananas
  • plant-based milk
  • ground flax seeds
  • apple cider vinegar

I love the tip from The Kitchn to mash bananas with a potato masher.

Next, mix together the dry ingredients:

  • all-purpose flour (although whole wheat pastry flour works great too)
  • whole wheat flour
  • baking powder
  • baking soda
  • salt
  • chocolate chips.

Oh, and I sprinkled some Cacao Nibs on the top to give each bite a little pop. Cacao Nibs are crunchy and chocolate, but you can’t always find these at Target so if you don’t have them on hand, just chop up some chocolate chips and sprinkle those across the top. Whatever works!

Obviously, I’m not the only one who loves this banana, peanut butter, chocolate combination.

Adapting This Recipe

Here are some expert tips and tricks to adapt this recipe:

  • Be sure to use this Vegan Chocolate Frosting to ice this chunky banana bread cake recipe!
  • I prefer to make this as a chunky monkey cake 13X9 — to keep it simple. Serve it with either chocolate frosting or even this Vegan Vanilla Frosting.
  • Also, bake it into a layer cake, and add the pudding from this Vegan Banana Cream Pie recipe in between the layers. It would make a vegan peanut butter chocolate eclair cake. Leave out the chocolate chips to have a peanut butter eclair cake. Either way, it would be an amazing dessert!
  • Bake this cake into layers and add vegan ice cream in between the layers to make a chunky monkey ice cream cake. Be sure to store it in the freezer!
  • Make a chunky monkey banana peanut butter cake with chocolate peanut butter frosting by adding a 2 -3 tablespoons of peanut butter powder to the chocolate frosting.
  • You can spread the batter into loaf pans to create chunky monkey bread! It would be rich and moist and perfect to give away as gifts!
  • Finally, spread the batter into muffin tins and make chunky monkey muffins. What a great way to start out the day!

We LOVE this Chunky Monkey Banana Bread Vegan Cake recipe…especially this time of year.

  1. Delicious. I may have to change my baking plans and make this tomorrow! Can anything be better than chocolate and bananas? I think not! Thanks for sharing one of your go-to favorites!

  2. This cake sounds perfect! Unfortunately, I can’t use anything with chocolate as a fall-back recipe. Chocolate always disappears pretty quickly around here and I never have it in the pantry. But next time I buy chocolate chips I just may have to make this cake!

    • I feel your pain. We go through the chocolate here too. Hmm, maybe I’ll have to work on a back-up to the fall-back recipe. 😉

    • I’m so glad to hear this Ashley! Those flavors and the moisture and the frosting! It’s just so great! ❤️

  3. This cake was absolutely great! I didn’t have time for the cake to cool off completely so I didn’t use frosting and it was still amazing!

    • Hi Silvia. So glad you liked it! I’m usually a frosting girl, but this one with the chocolate chips in the cake makes it ok without frosting. 🙂
