The desserts have been spotted at participating locations in Florida.
The Turtle Brownie Sundae consists of vanilla soft serve with small pieces of chocolate chip brownie, hot caramel and hot fudge sauce, salted pecans, and whipped topping.
The Strawberry Shortcake Sundae features vanilla soft serve with chunks of white cake, strawberry sauce, and whipped topping.
As far as ingredients go, a wider roll-out would involve supplying just the brownies, pecans, and white cake to restaurants as rest of the components are already necessary for regular sundaes.
