The donut chain is adding bold and sweet flavors to the menu this month.

The sweet collection of handcrafted heart-shaped doughnuts includes new flavors this year.

The Las Vegas-based chain is preparing for the big matchup on Sunday, February 9 between the Kansas City Chiefs and the Philadelphia Eagles.

The new treats are frosted with Valentine's Day icing flavors and topped with sprinkles.

The chain is now celebrating Valentine’s Day at locations nationwide, with the return of its Cupid’s Choice and Brownie Batter donuts.

Starting Friday, January 31, the bakery-café chain will debut a selection of Valentine’s Day-inspired treats, including cakes and chocolate-covered strawberry creations.

The chain has introduced a twist on New Orleans' famous beignets, with new "YAYs" available for a limited time through early April.

The doughnut chain’s all-new collection is an exquisite arrangement of four heart-shaped doughnuts in a customized flower bouquet box.

As the official doughnut partner of the Vegas Golden Knights, Pinkbox Doughnuts will sponsor the team’s hockey game on Tuesday, January 28.

The Heart-Shaped Box collaboration is joined by other donuts available for Valentine's Day.
