Karo Frosting
Karo Frosting is a light, marshmallow-like frosting with a subtle sweetness, perfect for decorating cakes and cupcakes, especially suited for those who enjoy fluffy, glossy finishes.
Ingredients
Instructions
- Beat the egg whites and salt until foamy.
- Gradually beat in sugar until smooth and glossy.
- Boil the Karo syrup for a couple of minutes.
- Pour the hot Karo into the egg whites in a slow, steady stream while beating.
- Add vanilla extract and beat until well incorporated.
- Use the frosting immediately as it sets quickly and is best when used the same day.
Tips & Substitutions
For best results, make sure your mixing bowl and beaters are clean and free of grease. If you prefer a different flavor, consider adding almond or lemon extract instead of vanilla. If you need a sweeter frosting, you can increase the sugar slightly, but be cautious as it may affect the texture. This frosting is great for topping cakes or cupcakes, especially for Payday Cakes.
Serving Suggestions
This frosting is perfect for layering on chocolate or vanilla cakes. It pairs beautifully with Hershey Bar Fudge for a decadent dessert. You can also use it to top brownies or cookies. For a fun twist, try adding food coloring to match any occasion or holiday theme.
Storage & Reheating
Karo frosting is best used immediately, as it sets quickly. If you have leftovers, store them in an airtight container in the refrigerator for up to 24 hours. To reuse, allow it to come to room temperature and re-whip it lightly before applying, but note that the texture may change slightly.

Frequently Asked Questions
Can I use powdered sugar instead of granulated sugar in this recipe?
Using powdered sugar will change the texture of the frosting, making it less glossy and more dense. Granulated sugar is recommended for that smooth, glossy finish. If you only have powdered sugar, consider using a different frosting recipe that is better suited for it.
What should I do if my frosting is too runny?
If your frosting turns out too runny, it may be due to not beating the egg whites enough or adding the syrup too quickly. Try beating it a bit longer until it thickens. If needed, you can also add a small amount of cornstarch to help stabilize it.
Can I make this frosting in advance?
It is not recommended to make Karo frosting in advance, as it sets quickly and loses its ideal texture. However, if you must, store it in the refrigerator and re-whip before using. Keep in mind that the texture may not be as fluffy as when freshly made.
