A popular Dairy Queen item is the Blizzard, which is soft-serve mechanically blended with mix-in ingredients such as sundae toppings and / or pieces of cookies, brownies, or candy. It has been a staple on the menu since its introduction in 1985, a year in which Dairy Queen sold more than 100 million Blizzards. Popular flavors include Oreo Cookies, mint Oreo, chocolate chip cookie dough, M&M's, Reese's Peanut Butter Cups, Heath Bar (Skor in Canada), and Butterfinger (Crispy Crunch in Canada). Seasonal flavors are also available such as October's pumpkin pie and June's cotton candy. It has been argued that Dairy Queen drew its inspiration from the concrete served by the St. Louis-based Ted Drewes. On July 26, 2010, Dairy Queen introduced a new "mini" size Blizzard, served in 6 oz. cups. During the 25th anniversary of the Blizzard, two special flavors were released: Strawberry Golden Oreo Blizzard and Buster Bar Blizzard. Salted Caramel Truffle was released in 2015 during the Blizzard's 27th anniversary and Dairy Queen's 75th anniversary, and is still on the menu today.
