3 Musketeers Cupcakes

Here in the heat of the summer there’s nothing I crave more than a heavy chocolate, sugary cupcake.

Ok, fine I lie.

A little bit.


But I try not to compartmentalize my desserts into seasonal quarters.  I feel like that’s kinda mean.

Apples aren’t only for fall.  Citrus isn’t only for summer.  Pumpkin…well…ok, you’ve got me there…


I ‘m really not out to hurt any dessert’s feelings.  Nobody puts desserts in the corner.

Umm, too far?


So while you’re enjoying your watermelon and popsicles, I say break up the cool, light treats with an occasional gut-buster.  One won’t kill ya.

Plus, aren’t 3 Musketeers a sorta-healthy candy bar?

The commercials say that they are light and airy…which translates into healthy in my brain.

My husband tells me that I am a marketers dream come true.

Really, I’ll take any excuse to eat a candy bar.

So basically what I am trying to convince you is that these cupcakes are based in health food…like banana bread or zucchini brownies.

Candy bar health food.


So make them, eat them and go put on your swim suit.

3 Musketeers Cupcakes.

PhotobucketI used my chocolate cupcake recipe and halved it.  The original recipe makes 36 cupcakes, so I made 18.  Half.

Make your batter and fill your liners up just half way.

PhotobucketBake them for 5 minutes and pull them out of the oven and drop in 1 miniature 3 Musketeers piece, pressing gently into the partially cooked batter..

PhotobucketPop them back in the oven for 10-15 minutes until the cupcakes are set.  They will continue to bake around the 3 Musketeers piece.

Let them cool completely before frosting.


Now.  3 Musketeers frosting.  It’s kinda cool.

In a sauce pan on low heat, melt 15 oz. of 3 Musketeers pieces, or chopped bars, stirring frequently.

When the 3 Musketeers melt, they will be like a thick marshmallow consistency.  Like the picture in the top right…

PhotobucketMeanwhile, in your stand mixer cream together some butter and Marshmallow Fluff.  Add the melted 3 Musketeers to the butter and Fluff and mix away.

Add in some milk and powdered sugar and you’re set!

Pipe or spread the frosting on your cupcakes…

PhotobucketAnd if you’re interested in how the 3 Musketeers looks on the inside of the cupcake…

PhotobucketIt gets melty, making the inside of the cupcake super gooey.

It’s really summer food at its finest.

3 Musketeers Frosting

  1. In stand mixer cream together Marshmallow Fluff and butter, approx 1 minute, until smooth.
  2. In a large saucepan over low heat melt the 3 Musketeers candy bars. The mixture will resemble thick Marshmallow Fluff consistency when melted.
  3. Add the melted 3 Musketeers bars to the butter/Fluff mixture and beat mixture for 1-2 minutes until evenly incorporated.
  4. Turn speed to low and add in powdered sugar and milk.
  5. Turn speed up to medium and beat until smooth.
  6. The frosting consistency will be different than regular frosting and more “elastic”
  7. Pipe onto cooled cupcakes.

The frosting was good but super super sticky! I wonder what the frosting would be like without the marshmallow fluff. Not my favorite.


Can these be frozen?


I just fell in love!!! I make a chocolate mousse icing but this I cannot wait to try! You just made my day! You have no idea! THANK YOU!


I’m going to take these to the family reunion this year. May make it a devils food cake with the frosting tho. I had this recipe for the frosting 30+ years ago but lost it. Thanks much!


These look amazing! One question though: I want to make these for Father’s Day since my dad’s a huge 3 Musketeers fan; however, he doesn’t really like marshmallows or marshmallow fluff. Is there anything I could use as a substitute? Thanks!


I really love your blog..it is really so nice. You have a lot of recipes and I want to thank you ’cause you share with all of us. You’re not a selfish person…
So thank you thank you!!!


These look delicious!!! I would just like to know where I can find the liners that are in the picture.


Oh my yum! How in the world did you think of melting down the candy bars for frosting? Fantastic! I am going to totally try this!


I made the frosting for my son’s 6th birthday party yesterday and it was delish, but it didn’t hold up. I wanted to pipe it like you have here, but it ran down the sides. Hubby suggested I put them in the fridge to harden which helped a ton. I wonder what I did wrong? It was a hit none the less.


I want to make these for Thanksgiving, and was surprised by the amount of sugar for the cupcakes. Is 3 cups correct?

two things: first, the melting of the 3 muskateer bars… i have never ever thought to do that! thick chocolately fluff… sounds like heaven. I have to try this frosting sometime Shelly. All of your inventive recipes keep me coming back, I just love it. second, baking the cupcakes just tin cups is something I’ve never seen before! I love that idea.. less dishes!

Lauren at Keep It Sweet

That frosting just looks so creamy and fluffy and perfect… like any perfect 3 musketeers bar!


Yummy, yummy. I love these cups. What is your take on baking in them? Hard to get the cupcake out? I have placed a baked cupcake in these but never directly baked in them.


I definitely see where you’re coming from. That airy 3 Musketeers center HAS to be good for you! Otherwise it would defy physics.


That frosting is too cool!! I would have never in a million years thought about doing that!

Thanks for sharing 🙂
