Chocolate Chunk Banana Snack Cake

It’s snack time! With the start of October, the internet makes me feel like I should be sharing pumpkin recipes. I mean pumpkin this and that is everywhere. But I don’t really feel like pumpkin right now. Actually, I’m not so ready for fall at all. I wish I could get two more months of summer in. Like every year. So that’s where this quick little banana snack cake comes in.

Simple ingredients.

And simply yum.

You can use mini chips in your batter, but I like them chunky with chocolate.

Enjoy the baked banana cake by itself or top it with frosting.

That’s right. Let’s slap on a layer of creamy chocolate frosting.

One of the reasons I love snack cakes so much is baking everything in one big, no-fuss, easy layer. Plus, that means lots of little squares to snack on for the next few days.

Chocolate Chunk Banana Snack Cake

Prep Time 15 minutes
Cook Time 35 minutes
Total Time 50 minutes



  • 2 cups all purpose flour
  • 1-1/2 tsp baking powder
  • 1/2 tsp salt
  • 3/4 cup unsalted butter, room temperature
  • 1 cup sugar
  • 2 eggs
  • 1 tsp vanilla
  • 1/2 cup milk
  • 1 cup mashed bananas (about 2 large bananas)
  • 1-1/2 cups chocolate chunks


  • 1 cup butter, room temperature
  • 3 cups powdered sugar
  • 1/3 cup unsweetened cocoa
  • 1 tsp vanilla
  • 1 Tbsp milk


  1. Preheat oven to 350 degrees Fahrenheit. Grease and flour a 9 X 13 inch baking dish.
  2. In a medium bowl, whisk together flour, baking powder and salt until combined. Set aside.
  3. In a mixing bowl, cream butter and sugar. Add eggs and vanilla and mix until combined. Add milk, continuing to mix until combined. With the mixer on low, slowly add flour and mix until just combined. Mix in mashed bananas. (Note: I used a food processor to mash bananas right before adding to the batter.) Stir in chocolate chunks.
  4. Pour batter into prepared dish and bake for 30-35 minutes or until done.
  5. Remove from oven and cool completely.
  6. For frosting: Using a mixer, beat butter and vanilla until smooth. Sift powdered sugar and cocoa together and slowly add to mixer while on low. Increase to medium and beat until completely incorporated. Add milk a teaspoon at a time until desired creaminess.

  12. Chocolate with banana make a great couple for dessert, your babana chocolate cake look delicious and irresistible

  13. Beautiful! It looks like you may have lightly dusted the chocolate chunks with flour. If not, would you recommend doing that so they don’t sink to the bottom of the batter? PS – even your sliced bananas look better than everyone else’s ;)
