Answer:
the cupcake is the personified object.
Step-by-step explanation:
Since a cupcake cannot actually "beg" to be eaten, that is its human quality. It is an inanimate object using a human quality. The author is using the human quality of begging to demonstrate the temptation and desire of the characters need to eat the cupcake. They are making it seem as though the cupcake wants to be eaten when in reality is it the character who cannot resist it.
