Which dessert combines cheesecake and chocolate sauce at Outback?

The dessert that combines cheesecake and chocolate sauce at Outback is the Chocolate Thunder from Down Under. This dessert is a rich combination of a chocolate pecan brownie topped with vanilla ice cream, drizzled with both chocolate sauce and possibly a hint of chocolate cheesecake flavoring, creating a decadent experience for chocolate lovers. The incorporation of cheesecake adds a creamy texture that complements the rich brownie and cold ice cream, making it a standout choice on the menu.

The other desserts listed, such as New York Style Cheesecake, primarily focus on the classic cheesecake flavor without the chocolate sauce element, while the Chocolate Lava Cake features a molten chocolate center and is distinct from cheesecake. The Chocolate Chip Cookie Sundae offers a different blend of flavors, focusing more on cookies and ice cream rather than the cheesecake-chocolate combination. Thus, the unique pairing of cheesecake and chocolate sauce is why Chocolate Thunder from Down Under is the correct answer.
