Marshmallow Candy-Stuffed White Chocolate Cupcakes with Fluffy Buttercream Frosting

I normally don’t make cupcakes because they’re a bit of a PITA. Cupcakes require more precision and patience than a pan of bars.

Carefully pouring the batter into molds or liners, taking care not to overfill, cleaning up any drips on the side of the pan before baking, and then frosting each one individually makes them more of a chore.

Another reason I don’t make cupcakes is because most recipes yield a couple dozen cupcakes.

After I’ve had one or two three cupcakes in a 24 hour period, there is really no need to have another 20 or so just laying around.

I love desserts but let’s face it, a little self-control is a good thing.

So is a recipe with built-in portion control and this one yields just six cupcakes.

Amen for small-batch recipes.

Marshmallow Candy-Stuffed White Chocolate Cupcakes with Fluffy Buttercream Frosting

I thought it would be fun to stuff these fluffy little clouds with special edition 3 Musketeers Marshmallow fun-size candies.

Everything, including cupcakes, tastes better when paired with marshmallows and chocolate.

3 Musketeers Marshmallow candies

During the last few minutes of baking, I carefully inserted one bite-sized 3 Musketeers into each of the six cupcakes. I wasn’t sure if the 3 Musketeers were going to melt or not. The verdict was no, they did not. The dough continued to rise and envelop the candies, but they didn’t melt.

Why they would melt in my trunk on a hot summer day and not in the oven is apparently one of life’s mysteries.

While the cupcakes cooled, I made enough fluffy buttercream frosting so that I could lick the bowl, the beater, and frost each cupcake with sky high amounts of frosting.

And still have a little extra frosting for a frosting-meets-spoon-standing-in-front-of the-refrigerator-at-12:36am party. The best kind of party.

I like a little food with my frosting.

3 Musketeers Marshmallow Candy-Stuffed White Chocolate Cupcakes with Fluffy Vanilla Buttercream Frosting (with Vegan and Gluten Free suggestions)

Makes 6 cupcakes

1 cup white cake mix (or golden, vanilla, or your favorite boxed mix)

1 large egg

3 tablespoons vegetable oil

1 teaspoon vanilla extract (clear is ideal if you want to keep these whiter)

1/3 cup white chocolate chips

six 3 Musketeers bite-size candies (or bite-size Snickers, Butterfinger, Reese’s Cups, Rolo, etc.)

Preheat oven to 350F and line a standard-sized muffin pan with paper liners. In a large mixing bowl, combine cake mix, egg, vegetable oil, vanilla, and whisk (by hand is fine) until batter is free from lumps and smooth. Pour batter into the muffin liners, divided equally among the six. Note: It may seem like there isn’t enough batter in each of liners, but the cupcakes rise considerably.

Distribute about 12-15 white chocolate chips around the top perimeter of each of the cupcakes. Bake for 11 minutes.

Remove pan from the oven, carefully insert an unwrapped 3 Musketeers candy into the top of each of the cupcakes, very lightly pressing it down just past the surface, and “breaking” the surface. Bake for an additional 3 to 5 minutes, until the edges of the cupcakes have shown the very first signs of browning. Remove from the oven and allow cupcakes to cool in the muffin pan before attempting to remove them. If desired, frost them or glaze them. Cupcakes will keep in an airtight container on the countertop or refrigerator for up to one week.

Frosting Variations

For Fluffy Buttercream Frosting (shown here) combine 1/4 cup softened butter, 2 to 3+ cups powdered sugar, 1/2 teaspoon vanilla extract (clear is ideal if you want to keep frosting whiter), and a splash of cream or milk as necessary, and beat until very fluffy and smooth (in a stand mixer, paddle for at least 3-4 minutes for extremely fluffy frosting). Frost cupcakes as desired with a spoon, pastry bag, or plastic baggie with the corner cut off.

For Cream Cheese Frosting, combine 1/4 cup softened cream cheese, 1 to 2 tablespoons softened butter (optional),  2 to 3+ cups powdered sugar, 1/2 teaspoon vanilla extract (clear is ideal), and a splash of cream or milk as necessary, and beat until very fluffy and smooth. Frost cupcakes as desired.

For Vanilla Glaze, combine 1/4 cup melted butter, 1 to 3 cups powdered sugar, 1/2 teaspoon vanilla extract (clear is ideal), and 2 tablespoons+ cream or milk, and whisk until very smooth. Glaze cupcakes as desired, either by dipping the tops into a bowl of glaze or drizzling the glaze over the top of cupcakes.

To keep vegan, choose a vegan cake mix, use a flax egg or other egg replacer, use vegan candy. Use margarine and vegan cream cheese as desired for the frosting. To keep gluten free, use gluten free cake mix and gluten free candy. Ensure all products used are suitable for your own dietary needs.

These cupcakes combine everything that is right with the world.

Golden, spongy, moist cake and white chocolate chips…

The fluffy marshmallow in the candies paired perfectly with the fluffy frosted tops.

Do you make cupcakes?  Do you have a favorite recipe?

Do you like 3 Musketeers candy bars? Favorite store-bought candy?

I “like” the original 3 Musketeers candy bars but I don’t “love” them, and I realize that’s a bit ironic because I chose to use them in these cupcakes.

However, the limited-edition marshmallow-filled 3 Musketeers caught my eye when I was stocking up on Easter bunny goodies and they caught my eye. I like them much more than the original 3 Musketeers bars and they’re more like a Milky Way Dark, which I adore.

Obviously these cupcakes can be made without using 3 Musketeers bars and any type of candy can be substituted, or none at all. Between the white chocolate chips and the frosting and the cupcakes themselves, you won’t necessarily miss the candy.

In terms of storebought candy, I’ll never say no to good old-fashioned Peanut M & M’s, Rolo, Butterfinger, Reese’s Cups, and Sees Candy is fabulous.

Thanks for the Yumvelope Healthy Snacks Giveaway entries, also.

Have a great week!

  1. I guess I am an odd one out, I LOVE cupcakes! I actually run a part time home based cupcake baking company on the side. I get so excited trying new recipes and decorating each individual cupcake, finding new and fun baking cups, or wraps, sprinkles, edible glitter. I haven’t tried baking candy into my cupcakes yet, but you can see some of my creations at https://www.facebook.com/pages/Custom-Cupcakes-by-Tracy-Weinstock/221977684498087. I also have the self control problem jjuusstt a little bit, so when I am baking for myself smaller batches are better.

    My Cupcake Tips: Use a standard ice cream scoop to evenly divide the batter, it ensures you have even amounts in each cup and cuts down on drips. Wilton’s pastry tips are readily available at any craft store and even Wal-Mart sells them- the one most people use is the 1M, with that being said, my favorite brand is Ateco (I found mine at a home store). There are many tutorials on YouTube showing how to ice cupcakes- from regular to fancy. The nice thing about piping is that if you mess up you can easily scrape it off, scoop it back into the bag and try again – plus whatever frosting is leftover you can squirt right into your mouth ;).

  2. How do you frost your cupcakes? They look so perfectly fluffy :)

    I do love cupcakes because of the personalized portion and they always look super cute. I have made many on my blog, from malted chocolate to sour cherry filled vanilla to blue velvet. I always enjoy them!

    1. I was telling a couple other people in the comments that I just use a spoon and dollop it on! I hate pastry bags b/c they waste so much frosting on the inside of the bag (a crime!) and I guess I must not have tried the right tips…I’d like to learn though!

  3. A six cupcake recipe is perfect! And, these look absolutely fantastic, too. What a great idea.

  4. Three musketeers are probably my third fave! Reese’s peanut butter cups being my first favorite candy and york’s peppermint patties being the second. After the musketeers come milky ways then chocolate covered cherries…

  5. This cupcake recipe basically sums up, what life should be : Fun, Sweet, Delicious and Unexpected. This is a must try!

  6. Agreed in cupcakes being a PITA, can’t remember the last time I made them. But this is a crazy and creative combo, my nieces would go nuts for these.

  7. Averie, these look SO GOOD! i love white chocolate anything. i love making cupcakes, but i’m not very good at frosting them.. well… i’m not very good at making the frosting photogenic! i need to buy some frosting tips and practice. in the meantime…. it’s just frosting.. tastes good no matter how it’s spread all over the cupcake :)

    1. I didnt pipe it, just spooned it carefully the best I could. Piping = wasted frosting on the inside of a bag = a crime in my mind :)

  8. Wow, these cupcakes look delicious! I think you did a great job given your concern over cupcakes! I’m with you, I always cut down the batch or give them to my neighbors!

  9. SO funny! I was thinking about putting together a six muffin recipe tomorrow! Seems like the perfect amount. Stuffed baked goods are awesome. Who doesn’t like a surprise?

    1. Can’t wait to see what you come up with b/c 6 is perfect. More than that and you better have company coming :)

  10. I hate making cupcakes because they are PITA, as you say :-) But, I do have a recipe that I love so much and that is always a hit, so I make them every once in a while. They are pumpkin cupcakes with salted caramel butter cream.

    I love 3 Musketeer bars, but haven’t had one in at least 15 years I would guess. I don’t even know if you can buy them anymore in Canada. I am going to be on the lookout though!

    1. And I remember that pumpkin cupcake link you sent me and now I can’t find it…I know if you say something is good, it’s really good. There are so many pumpkin cupcake recipes out there (thousands!) but I am all about the tried and true!

  11. I’m not ashamed to admit I’ve eaten frosting straight from the Betty tub on multiple occasions. Quality control, right? ;)

  12. That is some seriously fluffy frosting and I love the candy in there–sometimes I crave a few different things and stuffed cupcakes or bars takes care of that! I think my favorite store bought candy would be Reese’s and butterfingers .

    1. These cupcakes covered lots of bases b/c of the stuffage. Candy, cake, frosting all in one.

  13. I love cupcakes, but I rarely ever have them. The best storebought candy is Reese’s Peanut Butter Cups of course ;)

  14. I love using a piping bag and so I love making cupcakes … mostly because I want to frost something … I am not very good at using it, but thoroughly enjoy it. I had thought about making Tres Leches in cupcake form for a while and then when How Sweet It is did hers I decided to do mine … I must changed the whipped topping though … it did not fulfill the piping bag use I was longing for :) but your frosting surely will!

    1. I didn’t even pipe these…I just dolloped with a spoon and made twists the best I could…I am horrible with pastry bags and there seems like so much Waste! I hate wasting frosting on the inside of a bag :) LMK if you have a type/brand/tip of bag/tip that you love!

      1. Guess what today I piped my mashed potatoes ….

        I love using the round 1A from Wilton … because I love the no ridge look seen in these posts:

        I also used the 233 tip to make these grass cupcakes to take to the soup kitchen:

        As you will see from the pics … I am no expert but I love piping anything and have fun while doing it … soon your frosting recipe will undergo my piping magic … :)

      2. Thanks for all the links and pics! Having fun is the name of the game :)
