White Wonder Icing
White Wonder Icing is a classic, cloud-like frosting known for its light, glossy texture and sweet marshmallow flavor. A staple in vintage American baking, this icing uses a double-boiler method to create a billowy, stable meringue made from egg whites, sugar, syrup, and cream of tartar. The result is a beautifully smooth and glossy frosting that holds its shape when whipped, perfect for topping cakes, cupcakes, or vintage desserts like Heavenly Hash. It’s beloved for its simplicity and nostalgic flavor reminiscent of old-fashioned bakery treats and holiday confections.

Ingredients
  

  • ½ cup egg whites (unbeaten, about 4 large egg whites)
  • ½ cup sugar
  • 2 tsp white syrup (light corn syrup)
  • 1/16 tsp cream of tartar

Instructions
 

Step 1: Prepare Double Boiler

  • Set up a double boiler with simmering water in the lower pot. Place egg whites, sugar, syrup, and cream of tartar in the top pot or a heatproof bowl.

Step 2: Beat and Heat

  • Place over boiling water and beat with an electric mixer or hand beater for about 7–10 minutes. Continue until the mixture becomes glossy, stiff, and forms firm peaks.

Step 3: Remove and Finish

  • Remove from heat and continue beating for 1–2 minutes to slightly cool the icing. The result should be thick, shiny, and fluffy.

Step 4: Frost and Serve

  • Use immediately to frost cakes or cupcakes before the icing sets.

Tips

  • Chill the Jell-O until just beginning to thicken before folding ingredients so they don’t sink
  • Drain the crushed pineapple well to avoid a watery dessert
  • Lightly toast pecans for deeper flavor
  • Substitute walnuts if preferred
  • Fold gently to keep whipped cream light and fluffy
  • Add a handful of mini marshmallows instead of cutting large ones
  • For sweeter flavor, use maraschino cherries chopped and drained
  • Serve in individual dessert cups or a glass bowl
  • Can be made the day before and chilled overnight
  • Keep refrigerated until serving since it contains whipped cream
