Whisk both yogurts, the sugar and corn syrup in a bowl until combined. Pour into an ice cream maker and freeze according to the manufacturer's instructions.
For a soft consistency, serve right out of the ice cream maker. For a firmer texture, transfer the frozen yogurt to a covered container and freeze for up to 2 hours. Serve with assorted toppings.
