The Big Scoop Cookie Dough Blast consists of vanilla ice cream mixed with chocolate chip cookie dough pieces and topped with a scoop of chocolate chip cookie dough plus more chocolate chip cookie dough pieces.
The Big Scoop Cookie Dough Sundae takes vanilla ice cream and tops it off with caramel, chocolate chip cookie dough pieces, and the aforementioned scoop of chocolate chip cookie dough.
Prices for the new sundae start at $2.99, while the new Blast goes for 50 cents more. Both can be found at participating Sonic restaurants for a limited time.
