Having made it through two hours in the dentist’s chair recently, I rewarded myself to a malted at a place called “Shakes.” I’ve always preferred malteds to shakes when given a choice, and always vanilla ones. This was the first one I’ve had in several years; they’re just too sweet for me anymore. This one was an 8 on a scale of 10, requiring a spoon to “drink” it. Really good ice cream but not quite enough malted. I always used to ask for extra malted, but I figured a place called “Shakes” didn’t need the request. Still, I loved every drop bite.
To answer the original question, when I used to blend shakes or malts at home, I used milk, lots of vanilla ice cream, a drop or two of extract of vanilla, powdered malt if I had it, and like I really needed to, some sugar. Ahhhhhhh.
