This milkshake isn’t super thick, nor is it so intensely flavored that you have to stop drinking after three or four sips. It is cool and refreshing, with just enough peanut butter and chocolate that you know what you’re tasting. It has a little bit more peanut butter flavor than chocolate, much like a peanut butter cup. The actual peanut butter cup called for in the recipe is a nice touch (whether yours is melted, like mine, or not) but is optional. If you prefer your milkshakes to be very thick, add an extra scoop of ice cream and even a few ice cubes, if necessary.
