Ingredients

  • 1 1/2 cups sugar
  • a dash of salt
  • 4 egg whites
  • 3 tablespoons Karo syrup
  • 4 tablespoons water
  • 1 teaspoon vanilla

Instructions

  1. Mix sugar, a dash of salt, egg whites, Karo syrup, water, and vanilla together in a double boiler with boiling water, beating with an electric mixer for 7 minutes.
  2. Remove from heat and stir in vanilla.

Tips & Substitutions

For best results, ensure the egg whites are at room temperature for easier whipping. If you don’t have Karo syrup, light corn syrup can be used as a substitute. This frosting can be difficult to spread if over-whipped, so stop as soon as you achieve fluffy peaks. If you need a bit of color, consider adding a few drops of food coloring for a festive touch.

Serving Suggestions

This fluffy white cake frosting is perfect for topping cakes, cupcakes, or even brownies like 5 Nut Brownies (Fudge Type). It pairs beautifully with vanilla or lemon cakes, adding a light, sweet contrast. For a special touch, consider adding fresh fruit or sprinkles on top before serving.

Storage & Reheating

Store any leftover frosting in an airtight container in the refrigerator for up to a week. To reheat, place the container in warm water for a few minutes, stirring gently to return to a spreadable consistency. Be careful not to overheat, as this can affect the texture.
