Baskin-Robbins is featuring a Reese's Peanut Butter Cup flavor all through March, April, and May, offering it in stores as scoops and prepackaged quarts, shakes, and sundaes, the latter of which sounds particularly scrumptious: "This madness is not just a layer of Reese’s Peanut Butter Cups, but three scoops of Reese's Peanut Butter Cup ice cream. How to top that? Hot fudge wouldn’t be enough. Let’s also add Reese's Peanut Butter Sauce and some whipped cream. Just for good measure."
