  • 2 egg whites
  • 1/4 tsp. cream of tartar
  • 1 tsp. vanilla

Instructions

Tips & Substitutions

To ensure your Seafoam Frosting has the best texture, make sure your egg whites are at room temperature before beating. If you don’t have cream of tartar, lemon juice or white vinegar can be used as a substitute. For a sweeter flavor, consider adding a dash of almond extract along with the vanilla. This frosting pairs well with cakes that have rich flavors, such as chocolate or spice cakes.

Serving Suggestions

Seafoam Frosting is perfect for topping cakes, especially chocolate or spice varieties. Try it on cupcakes for a delightful presentation or use it as a filling between cake layers. It can also complement desserts like Baked Butternut Squash for a unique flavor contrast. For an eye-catching finish, consider adding some toasted nuts or sprinkles on top.

Storage & Reheating

Store any leftover Seafoam Frosting in an airtight container in the refrigerator for up to a week. When ready to use, re-whip the frosting lightly to restore its texture. Avoid freezing, as the frosting's delicate consistency may not hold up well after thawing.

Frequently Asked Questions

Can I use granulated sugar instead of brown sugar?

Yes, you can use granulated sugar for this frosting, but it will alter the flavor and color. Brown sugar adds a rich, caramel-like taste that complements many desserts. If you prefer a lighter frosting, granulated sugar works fine, but you may miss the depth of flavor.

How do I know when the sugar syrup is ready?

The sugar syrup is ready when it reaches the thread stage, which means it should be able to form a thin thread when drizzled from a spoon. You can test this by dropping a small amount into cold water; if it forms a soft thread, it’s ready to use. This is crucial for achieving the right texture in your frosting.

Why did my frosting not hold its peaks?

If your Seafoam Frosting isn't holding peaks, it could be due to under-beating the egg whites or not reaching the right temperature with the sugar syrup. Ensure you beat the egg whites to soft peaks before adding the syrup and keep beating until the frosting is thick and glossy. Additionally, make sure all your utensils are clean and free of fat.
