Place the bowl over simmering water in a saucepan and heat, whisking occasionally, for 5 to 10 minutes, or until the mixture registers 160 degrees. It will thin out and turn white as the sugar melts. Transfer the cooked liquid to the bowl of a standing mixer fitted with a whisk attachment. Beat on medium-high speed for 6-8 minutes, reduce the speed to medium, add the butter a few pieces at a time, and continue to beat for another 5 minutes. Reduce the speed to low and add the confectionerâs sugar, milk, and vanilla.
