Since we’ve moved, one of the most commonly asked questions is, “Do you miss Toledo?” The short answer is.. no. Because it’s not the area that we miss, it’s the people. Our amazing neighbors, friends, hair stylist, dog groomer, etc. And the local bakery, which isn’t necessarily a person, I realize. But I love their frosting, so when I’m listing the people I miss, the bakery gets included, and so does Kroger.

Yes, guys I miss a bakery because they have the most amazing cake and frosting on the planet. Eric actually drove 3 hours round trip to Toledo for my birthday last month, just to pick up a Strawberries and Cream cake. My favorite not-made-by-me cake – in case you were wondering, this most definitely means that I win in the husband department.

I’ve been dreaming about frosting since we finished it – about 48 hours after Eric returned with it. Luckily we had some help in the eating department, otherwise I may have finished the entire thing on my own. It’s some seriously good cake, and some SERIOUSLY good frosting. Driving three hours for cake seems a little ridiculous when it’s not a birthday gift, so I decided so calm the craving with homemade marshmallow frosting. It’s not the same as that amazing Toledo frosting, but let me tell ya – it’s pretty dang delicious.

Yesterday, I woke up super early and decided to whip together a batch of cupcakes. I needed something to slather this magical marshmallow frosting onto, and let’s face it, eating out of the mixing bowl with a spatula would’ve happened. And since our summer vacation is less than 3 months a way – that simply can’t go down.

While I’ve been pretty obsessed with all things marshmallow since I was kid, I’ve never tasted marshmallow frosting made with actual marshmallows, so naturally, I had to make that happen. And although I toyed with the idea using plain white marshmallows for this recipe, I ended up choosing Campfire® Fruit Swirlers.

If you’ve never had a Campfire® Fruit Swirler, you are most certainly missing out. They’re bite size marshmallows that are exploding with fruit flavor. My dad is wholeheartedly in love with these marshmallows to the point that he can polish off an entire bag in about a day. I chose to use all strawberry flavored Fruit Swirlers in this recipe because I loved the idea of a pale pink frosting. However, you can use a combination of all 4 flavors, or even use Campfire® Mallow Bursts. The Fruit Swirlers did impart a slight fruity flavor to the marshmallow frosting, but the true vanilla marshmallow goodness definitely shines through.

Random fact – did you know marshmallows are sold as candy in the U.K., rather than an ‘ingredient’? The things you learn when your bestie is married to a Brit. I guess it gives my dad a little more justification for eating them by the handful, right?

I gotta warn you though, this frosting is bit more involved than a typical America-style buttercream because there is a cooking component, but I promise it’s super easy. And the light, fluffy texture is seriously amazing, so it’s definitely worth the 10 minute cook time. Trust me, you’ll be eating it with a spoon, spatula, and your fingers. Just don’t touch anything after!

Marshmallow Frosting

Yield: enough to frost 18 cupcakes
Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes

Marshmallow frosting made with Campfire® Fruit Swirlers is the perfect topping for cupcakes.


  • 2 large egg whites
  • 1 cup granulated sugar
  • 2 teaspoons light corn syrup
  • 1/3 cup cold water
  • 1 teaspoon pure vanilla extract
  • 30 Campfire® Fruit Swirlers Marshmallows (about 2 cups), cut in fourths for easier melting (I used kitchen shears)


1. Place egg whites, sugar, corn syrup and water in the top of a double boiler. Beat with a handheld electric mixer for about 1 minute.

2. Place pan over boiling water. Make sure the boiling water does not touch the bottom of the top pan. Beat constantly with an electric mixer on high speed for 7-8 minutes, or until it is stiff and glossy. Beat in vanilla and marshmallows. Continue beating until marshmallows are melted and frosting is smooth; about 2 minutes. Use immediately.


- You can substitute 2 cups plain miniature marshmallows for the Campfire® Fruit Swirlers.

- This marshmallow frosting will hold up to basic piping. I just snipped the bottom of a piping bag off and piped without an attached tip. You could also use a zip-top bag for this purpose.

- This marshmallow frosting is best served the day it is made and tastes best when it is at room temperature.

- One batch makes enough to generously frost 18 cupcakes.

First of all, it was probably not the best idea to stand over the hot stove at 36 weeks pregnant, right after baking cupcakes at 350! However, I wanted a substitute for cream cheese frosting for carrot cupcakes and this definitely fit the bill. This icing was delicious, basically like homemade marshmallow fluff. If you are looking for something substantial like a buttercream, this is not it, but it was perfect for what I needed!

I tried this with the campfire Carmel marshmallows on chocolate cupcakes with a Carmel center.  They were divine. Thank you for giving me something else to be addicted to!! Lol   Ps... I shared this with my relatives in Brazil, and they were excited until I found out that there are no marshmallows in Brazil for some reason... that’s a thinker

Can this frosting be dipped in chocolate?

Thanks for the recipe.

Hello! I haven't attempted dipping this recipe in chocolate, so I am not sure of the result. If you happen to give it a try, I'd love to know how it turns out. Thanks so much for stopping by. -Jamie

Hey Jamie, thank you so much for sharing this, I look forward to trying this. We don't have campfire fruit flavours here in Australia, but we do have flavoured marshmallows, so I'm sure they will suffice. We have marshmallows here as lollies (we call candy lollies) or confectionery at least, though we also use them for camp outs. A lot of fun. But thank you again
