Cheez-It turns 100 this year, and the brand is celebrating with a limited-time Cheez-It cake created by Chef Stephanie Izard. Available nationwide from 5/17 to 5/20 on Goldbelly for $49, the Cheez-Itennial Cake is bursting with an entire box of Cheez-It crackers, from the ground Cheez-It flour in the batter to the Cheez-It shortbread crumble between each layer. The cake is balanced to salty-sweet perfection with swirls of caramel throughout and chocolate-covered Cheez-It crackers popping out the top to join the party.
