Get the fries ready — fast food chain Wendy's is releasing a new flavor of Frosty for a limited time. 

In honor of the chain's 50th anniversary, Wendy's created a birthday cake-flavored sundae to celebrate the milestone. Wendy's was founded in Columbus, Ohio on Nov. 15, 1969. 

"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," Wendy's said in a statement. "It’s a birthday party in a cup (no off-tune singing or party hat required)!" 

For a limited time, you can get a small Birthday Cake Frosty for $1.49 or the sundae for $2.19.
