SAN DIEGO — A Southern California doughnut shop has come up with yet another guilty pleasure gone viral: a gigantic doughnut stuffed with a Pop Tart filling.

Donut Bar, with outlets in Fountain Valley and San Diego, calls the 1-pound creation the “Big Poppa Tart Donut.”

It’s appeared on “The Ellen DeGeneres Show,” “The Steve Harvey Show,” BuzzFeed and TV news.

The 2-inch-thick square is stuffed with strawberry jam and a strawberry Pop Tart, then topped with diced Pop Tart, sprinkles and drizzled jam.

There’s also a second flavor: S’mores.

Donut Bar sells about 150 of the doughnuts daily, at $4 each.

Owner-baker Santiago Campa tells the Orange County Register that the doughnut was supposed to be a one-week special, but it’s become so popular, he couldn’t pull it off the menu.
