Taco Bell has partnered with New York-based dessert company Milk Bar to launch new Birthday Cake Churros for a limited time.

Churros, of Spanish origin, are traditionally made with a flour-based batter that’s deep fried and dusted with a cinnamon-sugar blend, according to the Encyclopedia Britannica. The sugary treat is usually eaten in the morning and is served with a chocolate sauce for dipping.

Taco Bell's new Milk Bar Birthday Cake Churros are a sweet, frosting-filled collab that are sure to go fast. Bring extra napkins and a party hat.
