Make your frosting fresh!

This frosting is made using simple ingredients. I’ve left out the There are no preservatives or corn syrup being used here. I would recommend making this frosting the day you’re going to serve your dessert. Otherwise it will lose its fluff and turn to liquid.

All you need are 4 simple ingredients!

Eggs – for this recipe, we’ll only be using the egg whites. And it’s easier to separate your eggs when they’re cold. You can use the egg yolks for a bunch of different recipes. My favorite ones are my Luscious Pastry Cream, Boston Cream Pie and my Paris Brest Recipe.

Caster sugar – Caster sugar is a finer version of regular granulated sugar. It is often used for meringues because it dissolves quicker which means there’s less chance of overwhipping the meringue. Can you use granulated sugar instead? Yeah, you can. Just be careful not to overwhip the frosting. What does overwhipped frosting look like? It looks like little bits of scrambled egg in your frosting that melts within hours of being used.

Cream of tartar – is an acidic powder and when used in small amounts helps stabilize meringues like so that it can hold stiff peaks.

Vanilla Extract – Always use good quality vanilla extract when baking, it makes a huge difference. I have a great recipe here for it if you’d like to try your own!
