Peanut Butter-Banana Cupcakes with Marshmallow Cream Cheese Frosting

My favorite sandwich, growing up, was a peanut butter-banana sandwich with marshmallow cream slathered on it. It was delicious and easy to prepare. Marshmallow cream was a precious item purchased from the grocery store.

I never thought there was anything wrong with it, until one day during high school, I was having a discussion about the sandwich, with my art teacher. She said it was a gross combination, and it was loaded with carbs and sugar (Atkins was in full swing, at this time).
After that, I decided I needed to retire my sandwich, and pick a new favorite. I didn't want to eat a sandwich that was bad for me.

Since then, I haven't eaten a PB-B&MC sandwich. But I still really like that flavor combination! That's what inspired my Peanut Butter-Banana Cupcakes with Marshmallow Cream Cheese Frosting. These rose perfectly, were moist, and delicious.

Peanut Butter-Banana Cupcakes with Marshmallow Cream Cheese Frosting

1 2/3 cups all purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
3 tablespoons creamy natural peanut butter
2 tablespoons unsalted butter
3/4 cup firmly packed light brown sugar
1 1/2 teaspoons vanilla extract
2 large eggs
3/4 cup finely mashed ripe banana
1/2 cup milk

4 ounces cream cheese, softened
2 tablespoons unsalted butter, softened
3/4 cup marshmallow cream

1/3 cup milk chocolate chips, melted

Preheat oven to 350 degrees F. Line 12 muffin cups with wrappers.

In a medium sized mixing bowl, sift together flour, baking powder, baking soda and salt.
In a large mixing bowl, using a mixer on medium speed, beat together peanut butter, butter and brown sugar until creamy, about 1 minute. Beat in vanilla, eggs and banana until well combined, about 1 minute. Beat in flour mixture gradually, alternating with milk, until well combined (Don't forget to scrape down sides of bowl!).

Divide batter evenly into muffin cups. Bake at 350 degrees F, for 20-23 minutes, or until a toothpick inserted into cake comes out with moist crumbs attached. Cool for 15 minutes before transferring cakes to a wire rack to cool completely.

To make the frosting, in a medium sized mixing bowl, using a mixer on medium speed, beat cream cheese until creamy, about 1 minute. Beat in butter until well combined. Beat in marshmallow cream until well combined. Spread frosting on cupcakes. Drizzle with melted milk chocolate chips.

Yield: 12 cupcakes


  1. "Pan metron ariston" or everything in moderation Emiline. It is OK to have your favourites once in a while even if we are told they are bad for you. The cupcakes are a good substitute though:D

  2. That sounds like a delicious flavor combination-especially when you add that chocolate drizzle. I hope you'll enjoy your sandwich again and forget about the warning from your art teacher. Some people can take all the fun out of food.

  3. WOW OH WOW..these cupcakes are absolutely divine!!


  4. I think your teacher had a very stupid moment - that is not the way of talking to a kid about something they like to eat. She could have made her point differently.
    And these cupcakes are absolutely beautiful, Emiline!

  5. okay. obviously peanut butter and bananas are a delicious combination. cream cheese frosting enhances anything and everything it touches. my only doubt would come with the marshmallow cream, but since i've been known to eat it right out of the jar, i don't see how it could it could be a bad thing here. i definitely deem this worth a try!

    and shame on your art teacher for spoiling your treat.

  6. These cupcakes look fabulous! I had my first peanut butter and marshmallow creme (fluffernutter) sandwich the other day. DELICIOUS!

  7. I LOVE peanut butter and banana, but i've never tried it with marshmallow cream. that was so mean of your teacher, to ruin your favorite sandwich!
    and the cupcakes look great! i think you've inspired me to make a peanut butter sandwich for breakfast!

  8. You and Jenny at Picky Palate with your peanut butter and banana concoctions - I want to make them all! And a marshmallow cream cheese frosting - I'm sold!!

  9. peanut butter and banana was in my top two and I was just talking about peanut butter and marshmallow cream just two minutes ago...

  10. When your young is the only time you can eat like that. Your teacher was just jealous you load the carbs.

  11. Oh good grief, just come make these for me before I go insane. They look and sound divine!

  12. I don't know what I like the most: the cupcakes or the frosting. Good thing they work as a team ;). I adore the chocolate drizzle!

  13. aaaah two of my current favourite addictions put together! YUM! :D

  14. Emiline, gasp to take in breath here... OMG those cupcakes are absolutely divine!!

    Rosie x

  15. Perfect combination Emiline! All of my favorites in one little perfect cake, beatiful!

  16. Love a good cupcake Emiline. The flavours you chose are quite a combination. You should release your own baking book!

  17. Yes, I'd like a dozen of those, please :0)

  18. You should have told your art teacher to shove it and that Dr. Atkins died of heart failure.

    Elvis and I are both craving one of those cupcakes. YUM.

  19. They look delighful, Em.

    But after eating bananas all my life with no ill effects, last year I suddenly developed an allergy to them. Oh hum. At least I can look and imagine the flavor.

  20. well, all I can say is that she must have been a lame art teacher, because EVERYONE knows that marshmallow cream is an art form.
    You can make some cool stuff out of it!
    These cupcakes make my tummy gurgle. That's awesome.

  21. Fluffernutters are a beautiful thing. A word of advice though... ALWAYS make sure you have milk near by. I swear they can stick your mouth together.

    Maybe mom did that to shut me up...

  22. Emiline-
    You will probably outlive her. Bananas are good for you, peanut butter is good for you, and a little sugar won’t hurt you! The cupcakes look delicious!

  23. I've never heard of this flavor combo together, but your photos have won me over!

  24. i dreamt of something like this last night. i never knew it exist for real and it sounded this good, peanut butter banana cupcakes with marshmallow cream cheese frosting! awesome!! you really never run out of delicious ideas!

  25. I just love the flavor combo here. These look just fab.
    A must save recipe for sure.

  26. I love fluffernutters. I never thought to add bananas to them (BTW, that teacher should know they're not all bad. PB and bananas are very good for you and I love to put my PB on whole grain bread).

    The cupcakes look awesome. PB and banasas are such a great combination.

  27. YUMMY! Love the flavor profile. Good job.

  28. Valli- Good advice!

    Prudy- The chocolate drizzle was pretty good.

    Maria- Thanks!

    Patricia- Thank you!

    Grace- Thanks!

    Mary- Yes, they're good.

    Dessertobsessed- Now I want a peanut butter sandwich for breakfast!

    Deborah- You're right!

    Doggybloggy- That's weird.

    Glamah- She was actually pretty nice. I think she just had a bad day.

    Mrs. L- Thanks!

    Lore- Thank you!

    Maninas- Thanks!

    Peter G- Maybe....we'll see.

    Jan- That's weird. That happened to my friend and mangoes.

    Catherine- Marshmallow cream is an art form.

    Adam- Yes. Milk.

    Dhanggit- Sounds like a good dream!

    Lisa- Thanks!

    Dawn- Thanks!

    Rachel- Thank you!

    Aimee- Thanks.

  29. I hate what Atkins did to people's attitudes about food. That sandwich sounds awesome! And so do these cupcakes :). For the record, I used to love peanut butter and honey sandwiches with banana...

  30. peanut butter and banana sounds fantastic together. i really like the presentation too.

  31. I think these cupcakes are better than the sandwich! ;)
    I agree with Val, everything in moderation! I love PB and Banana!

  32. Ohgu! some teachers are ... I don't find the word!! Look is not nice that we now don't listen them???? (Because we are not at school) dont tell the childs. Marìa Esperanza specially have problems with some teachers!
    Well I think your cupcakes are fabolus!! I like maeshmallow too!!! mmmmm.. Gloria

  33. I never had a peanut butter- marshmallow sandwish, but I have to tell you that this cupcakes look like the kind of thing I could eat without a lot of effort ;)!

  34. Those look good! I am going to have to try this peanut butter, banana and marshmallow cream combo!

  35. I like how you've turned the sandwich into a cupcake. Talk about creativity!

  36. Hi Em,

    I've been watching the weather and seen all the storms and tornadoes heading your way. I hope you're okay?

  37. I'm glad to know you're okay, Em. There were no storms in OK at all, all the bad weather was to the north of us, in Kansas and Missouri. So I'm sure your dad is fine.

  38. Love your blog!! This was one of my favorite sandwich combinations growing up. We weren't always the most nutritious in our family. Ahh, memories. Great looking cupcakes!

  39. I was a big fan of peanut butter, banana, and honey, but I never thought about adding marshmallows to the mix; good idea :).

    BTW, I made a strawberry rhubarb pie this weekend because your post inspired me :)...but it wasn't the prettiest thing :D!!! It was tasty though, I'm now a rhubarb fan :D.

  40. OMG you're killing me here with these amazing creations! :)
    What a way to go!!

    I'm passing an award on to you- you completely deserve it!

    Here's the link:

  41. What pretty cupcakes! What does an art teacher know about a tasty sandwich? Although I like to think that the balancing of healthful foods and "junk" foods is a bit of an art. That being said, Peanut butter and fluff rules.

  42. Ohh my lord those are beautiful!

  43. Now I'm not a baker. (I'm also new to your blog- gorgeous layout, by the way.) But these cupcakes seriously brightened an otherwise drab day. Also, I've been that teacher. Well, sort of. I tell my student to stop eating bags of fritos and then stop by a bodega on the way home and get a poptart. Not that peanut butter + bananas = fritos or poptarts. These are bookmarked.

  44. Geez, you need to start a cupcake business. I'll be your first customer. I would even fight for the first bite.

  45. Em,
    What an amazing cupcake!!! Tell me the truth, what did you do with the rest of the jar of marshmallow fluff?

    They wanted to outlaw it in Boston schools -

  46. Are you kidding me? These look AMAZING! I am so the sucker for banana. Yum!

  47. I just made these last night. Great recipe, the cake has a wonderful texture and I loved the flavor of the frosting. I think if (when)I make them again, I'm going to play with the peanut butter proportions a bit - I would have liked a bit stronger PB flavor to come through. Although I admit that could vary by brand too.

    Just a warning to anyone else that may try this - if all you have in the house is fat free cream cheese do NOT make the frosting with it. Like I said, the flavor was wonderful, but because I decided not to go to the store to get the real thing the consistency was way off. I ended up with more of a thick glaze than a true frosting.

    Oh well, the gang at the office is loving them anyway :)

  48. oh wow!!!! i've never had a pb banana sandwich but i'd sure love to try these cupcakes :)

  49. Jessica- Thanks for the review. Glad you liked them! There's no such thing as too much peanut butter.
    You can always chill the frosting, to make it firm up a bit. That's what I did. Like, 10 minutes.

  50. Emiline - I did try to chill the frosting for a little while but unfortunately it didn't work out. I did this entirely to myself - I keep the fat free cream cheese in the house for one purpose only and it is NOT baking! :) Unfortunately I frequently find myself in the position of having used up all of the real cream cheese and just dying to try a recipe that calls for it and thinking, maybe this once the fat free stuff won't mess this up. So far I've been disappointed every time. Obvious solution - keep more real, full fat cream cheese in the house :)

    Thank you for sharing your recipes, as a frequent baker I appreciate having somewhere to go for a little extra inspiration.

  51. I think these look just wonderful, Emiline, and I think you're very resourceful to come up with a recipe which reminds you of the treat you used to love.
    I agree the teacher could have been a bit more tactful! They sometimes have no idea how much of an impression they can make on a small child!


  52. Happy Fluffernutter Day, Emily!!!

    I just had to include this link in my Fluffernutter post today. Those cupcakes are to die for!!!

    Thanks for sharing...

  53. Made these today & just ate one. Fantastic! I live at 7500 feet & didn't make any adjustments other than a little extra milk because my flour gets so dry here. They maintained their height & are moist with just the right proportions of peanut butter to banana. Oh, I had to use chocolate frosting though because peanut butter banana with chocolate sauce was my favorite sandwich! Thanx for a GREAT recipe!!
