The sugar hit in desserts, cookies and chocolate has not been cut despite a government crackdown on sweet treats.
Public Health England has set a target of reducing the sugar intake from a host of popular foods by a fifth by 2020.
Its first year update indicates progress in yoghurts and breakfast cereals, but not in other areas.
PHE said it still represented a good start, although it expected faster progress in the coming years.
On average, the public ingest more than twice so much better sugar as is recommended.
PHE chief executive Duncan Selbie said: “Tackling the obesity crisis needs the whole food industry to step up, including with regard to those businesses that have as yet taken little or no action.”
