While fall may not begin officially until Sept. 21, we're already in the throes of pumpkin spice season.

Starbucks debuted the Pumpkin Spice Latte this week, and for those looking for a sweet treat to pair with their coffee, Krispy Kreme has you covered.

On Friday, the store's iconic glazed doughnut will become pumpkin spice flavored.

The bad news for pumpkin spice fans? The doughnut will only be available while supplies last on Friday. 

Krispy Kreme is also encouraging customers to share their pumpkin spice doughnut by using the hashtag #PumpkinSpiceOG and tagging the store, @krispykreme.
