The 12-year-old's mother called Upper Burrell Township police after discovering the drugs in a tub of I Can't Believe It's Not Butter in 22-year-old Stevie Hickey's freezer. The woman tells police Hickey spread the substance on two pieces of toast that Hickey gave to the girl.
Police say Hickey told the girl it was "parsley butter" but later acknowledged to police that it was marijuana.
The Valley News Dispatch in Tarentum reports Hickey remains free after waiving her right to a preliminary hearing on marijuana possession and child endangerment charges May 10.
Her home phone is disconnected.
