Banana Chocolate Swirl Cupcakes

The Story:

I needed to make something banana, due to the fact that I had 2 very brown bananas on my counter.  But I didn’t know if I should top them with cream cheese frosting or chocolate.  Cream cheese is basic and simple and chocolate frosting on a banana cake doesn’t always photograph well for me.  So I decided to do both![end-story]

Banana Chocolate Swirl Cupcakes

Yield: 24 Cupcakes

Banana Chocolate Swirl Cupcakes


Banana Cake:
1 box Yellow or White Cake Mix
2 teaspoons cinnamon
2 ripe bananas, mashed
1 teaspoon baking soda
1 teaspoon lemon juice
1/3 cup oil
3 eggs
3/4 cup buttermilk
1/2 cup sour cream
2 teaspoons vanilla extract
Cream Cheese Frosting:
8 oz cream cheese, softened
1/4 cup butter, softened
2 teaspoons vanilla extract
3-4 cups powdered sugar
Chocolate Buttercream:
3/4 cup butter, softened
2 teaspoons vanilla extract
1/3 cup unsweetened cocoa powder
3-4 cups powdered sugar


1. Preheat oven to 350 degrees and line pans with cupcake liners.
2. Sift cake mix and cinnamon into a small bowl and set aside.
3. In a separate small bowl, finely mash bananas using an fork. Add baking soda and lemon juice, stir, and set aside.
4. In a large bowl, gently whisk oil, eggs, buttermilk, sour cream and vanilla extract together.
5. Add bananas to the wet ingredients and stir.
6. Add cake mix and stir until smooth.
7. Fill cupcake liners 3/4 full and bake for 15-22 minutes, or until and inserted knife comes out clean.
8. Chocolate Swirl Frosting: Cream Cheese Frosting: Beat cream cheese and butter for 2 minutes. Scrape down bowl and add vanilla extract. Slowly add powdered sugar until you reach your desired consistency. Remove from mixing bowl and place in a small bowl. No need to wash your mixing bowl, the chocolate buttercream will mix right in!
9. Chocolate Buttercream: Beat butter for 2 minutes. Add vanilla extract and cocoa powder. Slowly add powdered sugar until you reach your desired consistency.
10. To swirl the frosting, you will need 3 piping bags. Bag #1, fill with some of your cream cheese frosting (do not put in too much). Bag #2, fill with some of your chocolate buttercream (again, not too much). Bag 3, fill with your desired piping tip, then fit Bags 1 & 2 into it. This will take a little finessing, but you can do it! (See photo)
11. Pipe onto cooled cupcake and top with sanding sugar and fresh banana slices.

    I own a cupcake business and I’m always looking for new and exciting recipes. I love your blog! I just figured this trick out with the piping bags a few weeks ago. It adds such a different taste to the buttercream adding two different flavors in! <3 it 🙂

    Hi Lizzy,
    This frosting is beautiful!!!! I am trying to figure out how to pipe it. I understand how to place the bags and the tip. Do you swirl it in a circle? How do you make the chocolate always end up of the same side? I’m just in love with these cupcakes!!!!!

    These look so great! I just purchased some decorating bags that have two compartments in them. This would be perfect to try them! Great job, as usual!

    Hello Lizzy!

    I just wanted to let you know that I used the buttercream and frosting recipes from here to top your Easy Banana Cupcakes recipe and it was divine! I love the taste of the buttercream and the frosting together as well as all those who had a cupcake. It received rave review so again, thank you!

    What a great idea for the frosting! I don’t think I’d have the patience for it and would probably end up with a much messier version though! haha

    This is gorgeous. Do you just snip the bags for the frosting and use the one tip then? LOVE!!!

    What a lovely idea for swirl frosting! I’m throwing my sister a surprise baby shower in June, and think I’ll try this out with two tones of blue 🙂

    Oh My goodness, how do you get your cupcakes so beautiful!? I’m going to die they are so pretty. All of them sound so good! I have tried the swirling thing , but it mixed together and came out kinda yellow in the middle.

    They are absolutely gorgeous! I am just itching to make them, but I have one question. I understand how you make the swirled frosting work with the three piping bags, but what tip did you use on your larger bag?

    Samantha says:

    Hi! I am making these soon!! So cute. When you place the two bags into the one, do you simply cut of the ends of the two bags before placing them in the larger? Or did you place two small tips on those and then into the larger? I’m hoping I can make this look pretty! 🙂 I may end up piping the colors on top of each other, lol!! Thank you!!
