Krispy Kreme has a scary good deal for Friday the 13th.

When customers purchase a dozen donuts or a 16-pack of minis at full price on Friday, September 13, they can get 12 Original Glazed Donuts for just 13 cents. To take advantage of the buy-one-get-one deal, Krispy Kreme fans must use promo code “13” when ordering in-store or online through the app or website.

Customers are allowed to purchase a maximum of one dozen at 13 cents each.

The donut shop recently added the Barbie x Krispy Kreme Collection to its menu for a limited time, in honor of the doll’s 65th anniversary.

Barbie fans have had access to four pink donuts since September 3. The limited-time treats — Barbie Pink, Malibu Dream Party, Barbie Berries ‘n Kreme, and Barbie Sweet 65th donut — are all a nod to the beloved toy brand.

The Barbie Pink Donut features an original glazed donut with pink buttercream and matching sugar sprinkles, plus a pair of classic Barbie sunglasses.

The Malibu Dream Party Donut is inspired by the Barbie DreamHouse. The unglazed donut is filled with cake batter-flavored icing and features a DreamHouse-inspired scene with “Malibu blue” icing, graham sand and frosting clouds.

The Barbie Berries ‘n Kreme donut features a strawberry cream-filled donut topped with white icing and purple and pink buttercream stripes. The heart is decorated with a classic Barbie “B” and a profile of the iconic doll.

Last but certainly not least Barbie-inspired is the Barbie Sweet 65th donut. This is an original glazed donut with chocolate icing and “Barbie Sweet 65th” sprinkles in the brand’s classic colors: pink, purple, blue, green, and white.
