The Dublin outlet of doughnut maker Krispy Kreme saw revenue of €3.86m over three months.
The figures suggest the shop made weekly revenue of almost €300,000 from September to the end of December 2018.
Accounts for Krispy Kreme Ireland Ltd show across the 13 weeks, the company made an operating profit of €579,000.
Its profit after tax was €457,000.
The shop employs around 100 people in Blanchardstown in north Dublin.
A spokesman for Krispy Kreme Ireland said the store is "the best performing" one across its network.
It can seat up to 77 people and also features a drive-through.
The shop opened in last September, but was forced to shut its 24/7 drive-through due to noise complaints.
In response, the drive-through opening hours were reduced to between 6.00am and 11:30pm.
A new traffic management plan was even introduced in a bid to cut down queuing time to around 15 minutes.
