The cakes are only available at Starbucks drive-thru locations in South Korea and come in three varieties: Red Velvet, Lemon Yellow Cake, and Moist Chocolate.
Like a Push-Up Pop, there's a stick that you push up into one end of a cylinder to raise the three-layered cakes out of the other end.
Compared to the cake pops that Starbucks offers here in the US, the Drive-Thru Cakes seem to offer a bit more cake with a slight less risk of frosting cracking onto your lap.
