Root Beer Float Marshmallows

I was surprised to find Root Beer Concentrate at my local grocery store in the baking aisle (with the spices and extracts - insta-buy!) and marshmallows seemed just the thing to make with it. Swedish pearl sugar makes the best topping for the mallows because it gives them extra sweetness and a little sugar crunch. My taste-testers remarked that the mallows tasted "fizzy" although no carbonation was added. I think that sensation can be attributed to the airy texture of the marshmallow.

If you can't find Root Beer concentrate at your local grocery store, then you can purchase it here. Just a little bit goes a long way! I can't wait to use it in all kinds of treats, but I'm also planning to try my hand at making - what else? - root beer! According to the directions on the back, all you need is 1/2 tablespoon concentrate, sugar to taste, and 1 quart of sparkling water. I'm already planning to add aromatic muscavado sugar to a batch, and maybe some cherry syrup (I like Monin brand) for a cherry root beer cola.

I made some teeny-tiny root beer floats in tall shot glasses. I added just 1/2 tablespoon vanilla ice cream to each shot - they were so fun!

I wish I'd gotten more pictures of these lovely mallows, but they were gone too soon! They are so fun and delicious. One of my friends called these a "Willy Wonka" creation, and to me, there's no better compliment.

Root Beer Float Marshmallows
Yields about 2 dozen marshmallows

The root beer concentrate will yield a light brown color in these marshmallows. I used Wilton brand brown food color to give the mallows a deeper, and more authentic root beer color but this is optional.

Gelatin base
4 1/2 teaspoons unflavored powdered gelatin
1/2 cup cold water

Sugar syrup
1/4 cup sugar
1/2 cup light corn syrup, divided
1/4 cup water
1/8 teaspoon salt

1/2 to 1 tablespoon root beer concentrate (such as Zatarain’s)
1/2 tablespoon brown gel food color
Swedish pearl sugar

Powder coating
1 1/2 cups confectioners’ sugar
1 cup cornstarch

Lightly coat an 8x8-inch baking pan with cooking spray.

Make the gelatin base: Whisk together the gelatin and cold water in a small bowl and allow it to stand for 5 minutes.

Make the sugar syrup: Stir together the sugar, 1/4 cup corn syrup, water and salt in a medium saucepan over high heat. Boil, stirring occasionally, until the temperature reaches 240°F. Meanwhile, pour remaining 1/4 cup corn syrup into the bowl of an electric mixer fitted with the whisk attachment. Microwave gelatin on high until completely melted, about 30 seconds. Pour it into the mixer bowl Set the mixer speed to low and keep it running. When the syrup reaches 240°F, slowly pour it into the mixer bowl. Increase the speed to medium and beat for 5 minutes. Increase to medium-high and beat for 5 more minutes.

Add the color and flavoring: Beat on the highest setting for 1 to 2 minutes more and beat in the root beer concentrate and brown gel food color. Pour the mixture into the prepared pan, using an offset spatula to smooth it into the corners. Cover the top of the mallow with Swedish pearl sugar. Let it set for 6 hours in a cool, dry place.

Make the powder coating: Combine the confectioners’ sugar and cornstarch in a large bowl.

Cut the mallows: Use a knife to loosen the marshmallow from the edges of the pan. Invert the slab onto a work surface, and then turn upright onto a powder-coating dusted work surface, so the pearl sugar is upright.Cut into 2 dozen pieces using a sharp knife. Dip the sticky edges of the marshmallows in more coating, brushing away the excess with fingers or a pastry brush.
Store the marshmallows in an air-tight container.

  1. HELLO! This is such a cool idea!! Totally crushing on these marshmallows. I mean, these seriously need to go in everything.

  2. So gorgeus!! I would like to taste these marshmallows!! Kisses from Spain!

  3. Making your own rootbeer is SO FUN! Not sure how this product compares to root beer extract, but for family parties we use dry ice in a big drink cooler. Sometimes we sit on the lid while it's fizzing (way fun) or tie it down with bungee cords (less fun). I think you should try it :)

  4. Root beer concentrate in itself is awesome, but root beer float marshmallows? Awesomeness meter is overflowing! Love how fun these are, but such a pity this wouldn’t be available to the UK.

    We do get some of the LorAnn Oils here, so might be worthwhile checking out if they have a root beer one, or using one of the other flavours would be fun, too. :)

  5. It looks delicious!! thanks for sharing!! xoxo
