"The sweet celebratory treat starts with our creamy vanilla Frosty mixed with the flavor of classic birthday cake then is topped with sugar cookie pieces and sprinkles," the company said in a press release. "It’s a birthday party in a cup (no off-tune singing or party hat required)!"
Though we're not entirely sure how long the flavor will stick around, we do know both are making their triumphant debut just ahead of the November 15 anniversary. The small Birthday Cake Frosty is available for $1.49 while the sundae upgrade will set you back $2.19.
Now if you're more of salty than sweet eater, Wendy's has a little something, something for you too. In October, the 2 for $5 meal debuted with all your favorites: the Dave's Single, Spicy Chicken Sandwich, and 10-piece Nuggets.
