Cut pitted cherries in half and place in a small saucepan over medium/high heat.
Add sugar and corn syrup to saucepan and stir. Let cook for 5 minutes, until the cherries have softened and the mixture bubbles slightly.
Remove from heat and let cool.
In a large bowl combine the two yogurts with a whisk. Add the cooled cherry mixture.
Follow your ice cream makers instructions to freeze the frozen yogurt.
Once the frozen yogurt is almost done, and still churning, melt down the dark chocolate chip in a microwave safe dish. Heat at 50% power for 30 seconds, stir, and repeat until the chocolate chips are smooth and lump free. Let cool slightly.
Drizzle into the ice cream maker slowly, while it's still churning the frozen yogurt.
Enjoy immediately for a soft serve treat, or place in the freezer for an additional 2 hours to enjoy a more ice cream textured treat.
