Officers from Central Scotland Police are yet to identify the woman, whose remains were discovered at Carbeth Huts in Blanefield.
A spokeswoman for the force said the fire was not thought to be suspicious, but the result of a "tragic accident".
About 20 firefighters from four stations were called in to tackle the fire on Friday.
Central Scotland Fire and Rescue Service said that by the time they arrived at the chalet the property was well alight, preventing them from making a rescue.
The woman's remains were found after the fire was put out.
A police spokeswoman said: "We are waiting for the formal ID process to take place, although the post-mortem has been carried out.
"There would appear to be no suspicious circumstances and a report will be submitted to the procurator fiscal."
