  • Love-Letter-Marshmallows-1

    Love letters are a sweet way to show someone you care—especially when they're made out of marshmallows! To make your own love marshmallows, start with the simple recipe below to whip up a batch of 'mallows from scratch, or cheat and use store-bought ones for a quick and easy project with the kids

    LOVE Letter Marshmallows

    Spell out your love with these sweet, gooey treats.

    Prep Time:
    Cook time:
    Servings: About 96 1" letters, plus corresponding cut-out pieces


    • icing sugar: 1 cup
    • envelopes unflavored gelatin: 3½ envelopes
    • cold water: 1 cup
    • granulated sugar (baker's sugar also works well): 2 cups
    • light corn syrup: ½ cup
    • salt: ¼ tsp
    • egg whites: 2
    • vanilla bean: 1


    Step 1: Spray a 13" x 9" x 2" baking tray with non-stick cooking spray and dust the bottom and sides generously with icing sugar (it's easiest with a sifter or small fine-mesh sieve). Don't worry about it if it's uneven or if it piles on in some places.

    Step 2: Place 1/2 cup cold water in the bowl of a stand mixer or mixing bowl and sprinkle on the gelatin. Let stand to soften the gelatin.


    Step 3: Place granulated sugar, corn syrup, remaining 1/2 cup cold water, and salt in a large heavy saucepan over low heat, and stir until sugar has dissolved.

    Step 4: Turn the heat up to medium and bring the mixture to a boil (don't stir!) until a candy thermometer reaches 240°F. Take the pan off the heat and pour over gelatin mixture. Stir until gelatin has dissolved. 

    Step 5: Beat mixture on high for about 10 minutes or until it turns white, thickens, and more than doubles in volume.


    Step 6: In a separate mixing bowl, beat egg whites just until they begin to hold stiff peaks. Pour egg white mixture into sugar mixture.

    Step 7: Split vanilla bean down the middle with a paring knife and scrape the seeds into the sugar mixture. Beat on low speed until just combined.


    Step 8: Pour mixture into prepared baking pan and smooth the top with a silicone spatula. Sift 1/4 cup icing sugar over the top. 

    Step 9: Chill marshmallow uncovered at least three hours, until firm. 

    Step 10: Peel marshmallow out of the pan onto a sheet of parchment or wax paper.

    Step 11: (If using store-bought marshmallows, start here.) Use a large, unserrated knife to cut marshmallow into 1/4" slices.

    Step 12: Sift or pat some icing sugar onto a slice of marshmallow. Dip 1" letter-shaped cookie cutters (I also used a heart-shaped cookie cutter) into icing sugar, tap off excess, and place on top of marshmallow slice.

    Step 13: Press down on cookie cutters to cut the marshmallows. Dip fingers into icing sugar and carefully remove marshmallow from cookie cutters. I found it worked best to loosen one side and peel the rest out of the cutter. If necessary, you can use a toothpick to gently push out any particularly sticky pieces.

    I liked the way the pieces of marshmallow looked after the letters were cut out just as much as the letters themselves! (You can see a picture at the top of this post.)


    Serving suggestions: Marshmallows can be eaten alone or used to decorate a cake.
