The shake features cascara spun into their spun with frozen vanilla custard and chocolate sprinkles. Shake Shake describes the flavor as sweet and fruity with notes of red currant and cherry.
Cascara (the word means "husk" in Spanish) tea is made by brewing dried cascara with water as you would any other tea.
The Cascara Shake can be found at Shake Shack locations across the US through September 30, 2019.
