I stand by the conviction that the special seasonally-released pumpkin-shaped Reese's Peanut Butter Cup is much, much better than the original. It's not just because there's more sweet, creamy peanut butter per serving than you find in the cup-shaped version. They're just somehow more delicious. And I'll keep eating them side by side—it's research!—until I've figured out the secret.
You might say that I'm a little peanut butter cup obsessed. And if you feel similarly, this is the milkshake for you. I set out to improve upon the unimprovable, to somehow capture the spirit of the Reese's Cup in drinkable ice cream form. This shake is just the thing to get you in a happy Halloween mood as you get your costume ready.
To layer the nutty flavor, I took a cue from these boozy Girl Scout cookie-inspired shakes and used butter pecan ice cream in addition to chocolate. Paired with smooth peanut butter, it's a dead ringer for the sweet, salty, delicious stuff inside a peanut butter cup.
To seal the deal, make sure you don't forget the salt. A generous pinch really makes the peanut butter pop. Think of a chocolate covered pretzel without salt. You're sad now, aren't you? And this is a shake meant to make everybody happy. Even if they can't figure out how to make their stash of pumpkin-shaped Reese's Cups last all year.
