People living near Krispy Kreme in Blanchardstown say the noise is keeping them awake at night.
The company is asking customers to be respectful of residents and is installing new signs to remind them not to beep their horns.
Sinn Fein Councillor Paul Donnelly, who lives nearby, admits he's "puzzled" by how popular the donuts are:
"I don't think people really expected it but hopefully it will calm down and I hope that people will respect the people who live in the apartments and who live around the area."
