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.

I 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.

A few muffin cups filled with chocolate cupcake batterBake 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..

A muffin cup with chocolate cupcake batter and a mini 3 Musketeers barPop 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…

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

Pipe or spread the frosting on your cupcakes…

It’s really summer food at its finest.

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

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!

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?

These are incredible! As a kid, 3 Muskateers was always my 2nd favorite candy bar behind Snickers. I loved that creamy, mousse-like filling!
