In the bowl of your mixer, add in the eggs, sugar & cream of tarter.(I used my glass mixing bowl because youre going to need it to be heat SAFE)
Set the bowl over a semi deep pan filled with a few inches of boiling water.
Heat while whisking constantly until the egg whites are warmed up (just WARM, not HOT) and the sugar has dissolved completely, roughly 4 minutes.
Remove from the heat and transfer to your stand mixer fitted with the whisk attachment.
Mix on HIGH, until the frosting is stiff, about 8 minutes.
Lastly, add in the almond (or vanilla) extract at the very end.
ENJOY!
