Commenters on the @costcohotfind Instagram video were quick to crave the sweet pie, with @lillybean_z saying, "You needed to keep this one a secret," while @lisavallefuoco_bayley said the pie was "basically a Reese's." Each pie is baked in-store and costs $19.99, and although some comments said the pie is not available nationwide, shoppers could see them hitting shelves in the near future.
