The new frozen dessert comes in six flavors: Chocolate Malt, Mint Cookies 'N Cream, Old Fashioned Vanilla, Peanut Butter Pie, Salted Caramel Pretzel, and Snickerdoodle.
Compared to their regular Dreyer's/Edy's Grand line, the Frozen Custard's main difference is that they include egg yolks. They seem to be thicker and heavier with 210 calories per 1/2 cup serving of the vanilla flavor (compared to 140 calories per 1/2 cup of their vanilla ice cream).
The new line was spotted on the shelves of Target by The Impulsive Buy in quarts at $3.89 each. Dreyer's / Edy's Frozen Custards look to be available nationwide (Target stores appear to be your best bet currently).
