Jason Priestley is back for one more "donut day in heaven."

The former 90210 star said he didn't have to think twice about returning to judge this year's Tim Hortons' Duelling Donuts competition. Last year, he awarded Hamilton-born Andrew Shepherd with a $10,000 cheque for his chocolate, caramel and pecan creation, The Tortoise Torte.

Besides being the birthplace of the defending champion, Hamilton is home to the first ever Tim Hortons. (At least, the first Tim Hortons doughnut shop, but perhaps not the first restaurant with the Tim Hortons name).

"Last year showed that Canadians go wild when it comes to donuts," Priestley said in a press release. "I can't wait to see what people create this year. And, I should warn my fellow panelists: donut tasting is no easy task. Poking holes - no pun intended - in these great donuts isn't as easy as it seems."

The competition allows people to go online and create their own virtual donut, starting Monday. 

After four weeks, the top eight finalists will fly to Tim Hortons headquarters in Oakville to pitch their pastry to a panel including Priestley, Jann Arden, Anna Olson and Ben Mulroney. 

Last year, more than 63,000 digital donuts were submitted, sparking a second competition this year.

The Über-Canadian panel won't have the final say on what doughnut will take the crown this year, and make it on the Tim Hortons menu. 

That job is up to Canadians who can vote online.

Last year's Tortoise Torte beat out the Oreo Borealis, as well as the Monkey C-Donut, Monkey Do-Nut and the S'more Of It. 

The competition itself was a spin off of a fake documentary on the show, "How I Met Your Mother" from February 2012. 

In the show, a strawberry-vanilla donut stuffed with a chocolate Timbit is named after the former "Beverley Hills 90210" star. The Vancouver-born actor made a brief cameo, and Tim Hortons jumped on the idea.
