On Monday, it’s Double Detroit Lions. Come Tuesday, it’s Butter Brickle. Wednesday is Candy Commotion. No, these aren’t secret plays in the Lions’ playbook; they’re different sundaes, flavors-of-the-day at Culver’s Frozen Custard. The Double Detroit Lions sundae is made with thick chocolate custard filled with Oreo cookie pieces and marshmallow crème. Or try the sundae with hot fudge, peanut butter sauce and Reese’s Pieces. The menu includes the burger that made them famous, the ButterBurger.
