White Mountain Frosting Recipe

Prep Time: 20 minutes

Yield: 6 Cups

This Recipe for White Mountain Frosting makes 6 cups of Frosting. That's kind of a lot. For a single batch of the Chewy Chocolate Sandwich Cookies with Marshmallow Filling you only need about 1 1/2 to 2 cups of Frosting/Filling… of course… if you want to add more….. So.... what to do with the rest? You can sit in a corner with a bowl and a spoon (might give you the mother of all tummy aches though....) Or You can bake Chocolate Dipped Cupcakes Or You can stick it in an airtight container... and find something else to use it for in the next week. I suppose you can also halve the recipe......


  • • 4 Egg Whites
  • • 1 cup Sugar
  • • 1/2 Cup Light Corn Syrup
  • • 4 Tbl Water
  • • 2 tsp Vanilla Extract


  • In a Stand Mixer, beat Egg Whites on high speed until you have Stiff Peaks... set aside
  • In a medium saucepan, stir together Sugar, Corn Syrup, and Water until combined.
  • Bring to rolling boil... stirring all the while
  • Wipe the side of the saucepan with a pastry brush dipped in ice water.
  • Stick a candy thermometer to the side of saucepan
  • Boil without stirring, until you hit 242 degrees F.
  • Turn the mixer with the egg whites in it to medium speed.
  • Pour hot sugar syrup SLOWLY in a thin stream into the egg whites.
  • Add Vanilla.
  • Beat at high speed for 10 minutes until stiff peaks form
  • Done!


BTW... it's easiest to use a stand mixer for this recipe.... you have to beat it for 10 minutes to get proper consistency, that's a long time to hold a hand mixer.
