What Inspired This Homemade Marshmallow Recipe?

I’ve never been a frequent drinker of sparkling wines, but I do always enjoy a glass at a wedding or celebration. It’s a nice way to mark the moment. Miniature bottles of Champagne or Prosecco are always a popular gift on TV sets, too. At one point in time, I had a collection of miniature bottles of bubbly lining an entire shelf in my apartment!

After my successful red wine marshmallow experiment I decided to play around with other types of alcohol-infused marshmallows. To start, I couldn’t resist making a bubbly batch.

Prosecco Marshmallow Ingredients

To make this homemade marshmallow recipe with Prosecco, start by gathering the following:

Edible Glitter Tips

The edible glitter in this recipe is entirely optional, but it is a fun way to make your marshmallows ultra-glam!

One word of caution: While it might be tempting to stir edible glitter into the marshmallow mixture, I highly suggest saving your sparkles and sprinkling them on top of the finished marshmallows instead. I tried incorporating glitter into my mixture, but once it increases in volume—and you’ve coated the marshmallows in powder—the sparkles disappear entirely. You’d have to use a LOT of sparkles in order to see them inside the marshmallow, and they’re far too expensive to waste.

Prosecco Marshmallow Packaging Ideas

These homemade Prosecco marshmallows are perfect for gifting, because they will keep well at room temperature for several weeks when stored in an airtight container. Plus, they’re fun to package!

These marshmallow pops would be a fun way to gift your marshmallows, as would these marshmallow-and-strawberry sticks. (After all, what goes better with Champagne than strawberries?) Natural bamboo skewers are readily available on Amazon.

Instead of cutting the slab into cubes, use a metal cookie cutter to make heart-shaped marshmallows instead. (See my rosewater marshmallows for inspiration.)

Fill a cello bag with marshmallows, then place it inside a plastic champagne flute for gifting. Or, gift them in a cello bag with a sparkly bow, tied to a miniature bottle of champagne!

Marshmallow Recipe Tips and Tricks

These marshmallows taste very strongly of champagne, even without the addition of a champagne flavor oil. (If desired, you could add a few drops of flavoring, like LorAnn Sparkling Wine Super Strength Flavor, but it definitely isn’t necessary.)

Do not attempt this recipe without a candy thermometer! (My go-to is this Taylor digital thermometer, but any good-quality candy thermometer will work.) And pay close attention to your the temperature of your sugar mixture–too cold or too hot, and your marshmallows won’t set properly.

Use lots and lots of oil or cooking spray! Spray your tin, your spatula, and your knife. Trust me, it will make your life so much easier. If you cover your tin of marshmallow overnight, be sure to spray the aluminum foil or clingfilm you use to cover the slab.

Pay careful attention to the way you line your tin. Not enough parchment or oil, and your marshmallow will stick to the pan. Visit this recipe for a more detailed guide to lining your tin.

Ingredients

Scale

Marshmallows:

185 milliliters Proscecco, Champagne, or other sparkling wine, divided
20 grams powdered gelatine (2 tablespoons)
400 grams granulated sugar (2 cups)
200 grams corn syrup (1/2 cup)
25 milliliters water (2.5 tablespoons)
1/4 teaspoon salt
Edible foil stars or gold glitter (optional)
Canola oil or nonstick cooking spray, for greasing tin and knife

Coating:

50 grams potato starch* (1/3 cup)
50 grams confectioner’s sugar (1/3 cup)

Instructions

Marshmallow Slab:

Line an 8×8-inch / 20×20-centimeter square tin with parchment, and coat generously with oil. Set aside until ready to use.

Pour 105 milliliters (1/2 cup) Prosecco into a large mixing bowl (if using a hand mixer), or the bowl of a stand mixer. Sprinkle the gelatine evenly over the water, and set bowl aside.

Combine sugar, corn syrup, remaining 80 grams (1/3 cup) Prosecco, water, and salt in a large saucepan. Bring mixture to a boil and boil, without stirring, until syrup reaches 240° F / 116° C on a candy thermometer.

Carefully pour hot syrup into gelatine mixture. Mix on high speed until very thick, about 10 minutes.

Using an oiled spatula, scrape mixture into prepared tin. Loosely cover with a well-oiled sheet of aluminum foil. Allow to set until firm, at least 4 hours or overnight.

Cutting and Coating:

In a small bowl, combine potato starch and icing sugar.

Cover a large chopping board with a sheet of parchment, and dust generously with starch-sugar mixture.

Turn marshmallow slab out onto dusted surface. Sift top of slab with more of the starch-sugar mixture.

With a sharp, well-oiled knife, cut slab into squares.

Toss cut marshmallows in additional starch-sugar mixture, making sure all sides are coated.

Sprinkle with edible glitter to finish.

Prosecco marshmallows will keep well for several weeks when stored in an airtight container at room temperature.

 

Notes

*Readily available in the kosher foods aisle of most grocery stores. If you can’t find potato starch, cornflour/cornstarch may be substituted.

Proper tin preparation is very important for this recipe. Please see this page for a step-by-step guide to lining your tin.
