The flavor features caramel and chocolate ice creams with chocolate cookie swirls plus chunks of chocolate chip cookie dough and peanut butter cookie dough.
Jimmy Fallon's first Ben & Jerry's flavor was Late Night Snack (created during his stint as the host of Late Night) which featured vanilla ice cream with fudge-covered clusters of potato chip and a salted caramel swirl. The flavor was discontinued in 2013 when Jimmy took the Tonight Show gig.
Like the previous flavor, all of Jimmy's proceeds from sales of The Tonight Dough will be donated to charity; specifically to SeriousFun Children's Network, which benefits children with serious illnesses and their families.
The Tonight Dough is available in pints at retail and grocery stores nationwide at a suggested price of $4.89. You can also find it at Ben and Jerry's Scoop Shops. As with the rest of their flavors, you can use the online Flavor Locator on their website to find it stocked near you (once it's actually added anyway...)
