The Delicious Miss Dahl struggled in the ratings and lost over a million viewers during its run, the Daily Mail says.
"Sophie is undeniably watchable, but this cookery show has not really worked out," a source explained.
BBC Two controller Janice Hadlow refused to confirm whether or not the programme will return but a BBC spokesperson described Dahl as a "real talent".
The representative added: "Now her series has come to an end we'll be talking to her about a number of new ideas. Some will be food-based and some may venture into new territories."
