A women who made local news headlines for allegedly drop-kicking her son's birthday cake at a bakery has been handed a new charge related to violence at an ice cream parlour.

Tricia Ann Kortes, from Oakland County in Michigan, appeared in court on charges of assault and battery over an incident at Ray's Ice Cream in Royal Oaks on 9 July, 2015.

Employees at the ice cream parlour did not know her name, but claim they recognised Ms Kortes in media reports about the cake incident in June this year.

The ice cream shop's CCTV allegedly shows the mother striking Ray's employee Linda Wallner on the head, ABC7 reports.

Ms Wallner says the 46-year-old was angry the shop didn't have her favourite flavour.

Ms Kortes was initially charged with disorderly conduct for kicking a "Superman v Batman" birthday cake intended for her son at a Kroger grocery store in Bloomfield Township.

Kroger employees said Ms Kortes was unhappy with how the cake turned out and went behind the bakery counter to "fix" it.

She was told she couldn't enter staff areas, at which point a witness says she threw the cake on the floor before stepping on it and shouting: "They f****** ruined my seven-year-old's birthday cake".

Ms Kortes has denied she drop-kicked the cake, saying it accidentally fell from her hand.
