For 2021 Halloween Season Boo Batter has been resurrected just in time for Halloween at Cold Stone Creamery! If you’ve never tried it, Boo Batter takes the ice cream chain’s Cookie Batter Ice Cream and adds some dark food coloring. Boo Batter is featured in the Trick or Treat Ice Cream, which is full of goodies like Oreos, Kit Kats, and M&Ms. You can get yourself a serving of Boo Batter throughout the month of October.
