The 551kg (87st) Churma Ladoo took three chefs and 23 volunteers, from the Shree Hindu Temple, four days to make. They plan to offer it to 5,500 people.
Hitesh Morjaria, from the temple on St Baranbas Road, is confident they now hold the record for the world's tallest, widest and heaviest sweet.
Guinness World Records will examine the evidence submitted by the temple.
The Churma Ladoo, made from ingredients including wheat, clarified butter, jaggery, oil, poppy seeds and nuts, measured 5ft (1.37m) by 6ft (1.8m) when it was finished.
Mr Morjaria said they were "originally going to make a 100kg ladoo" to be blessed and offered to their devotees during the religious event of Ganesh Puran.
"Then we thought 'why don't we challenge ourselves' to make a bigger one," he said.
"We contacted the Guinness Book of Records and found out that no record had been set for the biggest Ladoo."
The Ganesh Puran, which began on Sunday and lasts for eight days, is dedicated to the elephant-faced god Lord Ganesh.
The blessed sweet will be offered to people from all cultures at the end of each day and "we don't want anyone leaving without the Prasad," Mr Morjaria added.
The delicacy, which is normally the size of a tennis ball, is said to be Lord Ganesh's favourite food.
