Ingredients

  • 3 egg whites
  • 2/3 cup white corn syrup
  • 1/2 cup sugar
  • 1 teaspoon vanilla
  • dash of salt

Instructions

  1. Combine all ingredients in a large bowl.
  2. Beat on high speed until the mixture becomes very stiff.
  3. Use immediately to frost coconut cakes or other confections.

Tips & Substitutions

For best results, ensure your mixing bowl and beaters are completely clean and dry to achieve maximum volume in the egg whites. If you don't have white corn syrup, light corn syrup or honey can be used as substitutes, although the flavor may vary slightly. This icing can be flavored with almond extract instead of vanilla for a different twist.

Serving Suggestions

This fluffy marshmallow cream icing is perfect for frosting coconut cakes, but also pairs well with chocolate or vanilla cakes. Consider using it to top cupcakes or in layer cakes for added sweetness and texture. For a fun twist, it can be used to frost cookies or even as a filling for Muffin Cheesecakes.

Storage & Reheating

Marshmallow cream icing is best used fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. When ready to use again, rewhip the icing briefly to restore its texture before applying it to your cakes or confections.

Frequently Asked Questions

Can I use pasteurized egg whites instead of fresh?

Yes, pasteurized egg whites can be used as a convenient alternative to fresh egg whites. They are safe to consume and will still whip up nicely for this icing. Just follow the equivalent measurements on the packaging to ensure you have the right amount.

What if my icing isn't stiff enough?

If your marshmallow cream icing isn't stiffening as expected, continue beating it on high speed for a few more minutes. The mixture should become fluffy and hold stiff peaks. If it still doesn’t thicken, ensure that the egg whites were whipped to the proper consistency before adding other ingredients.

Can I color this icing for decoration?

Absolutely! You can add gel food coloring to the icing after it reaches stiff peaks. Start with a small amount and gradually add more until you achieve your desired color. Keep in mind that darker colors may require more gel, which can slightly alter the icing's consistency.
