Fluffernutter cupcakes.

April 15, 2010

I recently happened upon an article at… about cupcakes. Yes, cupcakes. When CNN covers the cupcake, you know it’s big. My only sadness is that the article wasn’t written by Anderson Cooper, or that it didn’t include pictures of Anderson Cooper eating cupcakes. But anyway, I digress. The article can be found here. Don’t let the stupid comments from people saying “DOOD SHATAP! CUPCAKES LAK, TOTES SUXZ0RZ!” distract you. These people complaining about the “too sweet” nonsense probably never had a homemade cupcake that didn’t come from a powder or out of a box. According to this article, apparently the “cupcake trend” isn’t a trend anymore, it’s a bonfide industry, not to mention “here to stay.” Awesome. So then my blog name won’t be outdated in a few months. ‘Macaron Rehab’ doesn’t have  nearly the widespread appeal Cupcake Rehab does.

My creamsicle Easter cupcakes reignited my love of marshmallow Fluff. I bought a huge jar of it without realizing I only needed 7 ounces for the full frosting recipe and I was going to halve it anyway. So I had a lot leftover. And I ate some of it, with a spoon, I’ll admit. Surprisingly, in two tablespoons, Fluff only has 40 calories. I would’ve thought it was more like 140. Anyway… I couldn’t possibly eat the ENTIRE jar, and not being one to waste such a delectable treat like Fluff, I thought of this: FLUFFERNUTTER CUPCAKES.

Fluffernutters, for those of you uninitiated in the ways of Fluff, are as follows:

A fluffernutter is a sandwich made with peanut butter and marshmallow creme. Its name comes from the common use of “Marshmallow Fluff” brand marshmallow creme.[1] It is particularly popular in the Northeastern United States and has been proposed as the official Massachusetts state sandwich.[2]

A fluffernutter is made by spreading peanut butter on a slice of white bread, then spreading an equal amount of some kind of marshmallow (small, large or cream) on another slice, and finally combining them together to form a sandwich. Variations of the recipe include wheat bread instead of white, and the addition of bananas, honey, or other ingredients that are compatible with peanut butter.

Delicious, right? Who wouldn’t love that? Non-nutritious sandwiches are awesome. Like Nutella sandwiches. Mmm.

Allright so anyway… fluffernutter cupcakes. Really easy concept. Peanut butter cupcake, frosting made with marshmallow Fluff, because I thought it was a cute idea.



  • 2 cups brown sugar
  • ½ cup vegetable oil
  • 1 cup peanut butter
  • 2 eggs
  • 1 ½ cups milk
  • 1 teaspoon vanilla extract
  • 2 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • 2 teaspoons cream of tartar
  • 1 pinch salt
  • ½ cup peanut butter chips


  1. Preheat the oven to 350 degrees F. Line a cupcake pan with paper liners, or grease and flour cups.
  2. In a large bowl, mix together the brown sugar, oil and peanut butter until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla. Combine the flour, cream of tartar, baking soda and salt; stir into the batter alternately with the milk.
  3. Mix in the peanut butter chips until completely combined. Spoon into the prepared muffin cups.
  4. Bake for 15 to 20 minutes in the preheated oven, until the top of the cupcakes spring back when lightly pressed. Cool in the pan for at least 10 minutes before removing to a wire rack to cool completely.


First you get:

  • ¼ cup unsalted butter, softened
  • 1 (7½ ounce) jar Fluff, or similar marshmallow cream
  • 3-4 cups confectioners’ sugar
  • ½ teaspoon vanilla extract

Then you’re gonna:

  1. Beat butter in a large bowl with mixer on high speed until creamy. Beat in marshmallow cream. Reduce speed to low, and beat in confectioners’ sugar and vanilla. Increase speed to high; beat until fluffy.
  2. Frost cooled cupcakes.
    I know you love that I matched the liners to the Fluff jar *wink*

Okay so these cupcakes didn’t look very good. They cracked on the top & just didn’t look right. However, they tasted perfect. And the frosting? Forget it. I could eat Fluff right out of the container anyway. It’s odd to be calling a Fluffernutter  ‘decadent’, but it really is. Decadence. It’s so rich it’s insane. They would be cute with a banana slice on top too, since a lot of people make Fluffernutters with banana. This is like the perfect kids cupcake. The frosting is so sweet it makes your teeth ache and the taste is really like a Fluffernutter! However this cake would transfer really well to a PB&J cupcake: fill it with grape jam or jelly, top it with peanut butter frosting and voila.

I couldn’t frost them in a fancy way, like I wanted, because my large coupler developed a big crack in it, and I had no disposable bags left. So I just lopped the frosting on with an offset spatula. Doesn’t look all that fantastic but what can you do? It does sort of remind me of the way the Fluff looks in the drawing on the jar… all pretty and swirly, and also the way it looks when you spread it over the peanut butter, and it has a sort of retro 50’s look, so maybe it worked out for the best. However, I was going to use these as a section of part two of the frosting tutorial, but this set me back. So this week I went and got myself a new coupler, some new disposable pastry bags, a brand spankin’ new tip, and some fancy liners… and I promise I’ll get that second tutorial up A.S.A.P. Speaking of liners, thanks to sweet estelle baking supply for the retro stripe liners. I used the green for my St. Patrick’s Day cupcakes and the orange on my honey cakes. I love them. After Sweet Cuppin’ Cakes Bakery & Cupcakery Supply, sweet estelle baking supply is one of my top stores for awesome liners & stuff. Then comes Bake It Pretty and Fancy Flours. I’m telling you, these four sites will have you spending ALL your money on liners, tips and other things you suddenly realized you “needed.”

  8. Hello there, I discovered your web site by
    the use of Google at the same time as searching for a comparable topic, your site got here up, it seems to be great.

    I have bookmarked it in my google bookmarks.[X-N-E-W-L-I-N-S-P-I-N-X]Hello there,
    simply changed into aware of your blog via Google, and located that it’s truly informative.
    I am going to watch out for brussels. I will appreciate if you
    continue this in future. Numerous other people will likely be benefited out of your writing.

  9. I do accept as true with all the ideas you’ve introduced
    to your post. They’re really convincing and will certainly work.
    Still, the posts are very brief for newbies. May just you
    please extend them a bit from subsequent time? Thank you for the post.

  10. The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.

  11. This is the right webpage for anyone who wishes to
    understand this topic. You understand so much its almost tough to argue with you (not that
    I really will need to…HaHa). You definitely put a new spin on a subject that’s been discussed for ages.
    Great stuff, just great!

  12. This design is spectacular! You certainly know how to keep a reader
    entertained. Between your wit and your videos, I
    was almost moved to start my own blog (well, almost…HaHa!) Excellent job.
    I really enjoyed what you had to say, and more than that, how you presented it.
    Too cool!

  13. Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.

  14. Sorry for the huge review, but I’m really loving the new Zune, and hope this, as well as the excellent reviews some other people have written, will help you decide if it’s the right choice for you.

  15. Hmm is anyone else encountering problems with the pictures on this blog loading?
    I’m trying to figure out if its a problem on my end
    or if it’s the blog. Any feed-back would be
    greatly appreciated.

  16. Nice blog here! Also your website loads up very
    fast! What web host are you using? Can I get
    your affiliate link to your host? I wish my web site loaded
    up as fast as yours lol
