In medium bowl, mix cream cheese and sugar until smooth. Place half of the mixture into another medium bowl. Using whisk, beat blueberry yogurt into 1 bowl and peach yogurt into the other. Gently spoon and spread peach yogurt mixture over blueberry yogurt mixture in bowl. Freeze about 1 hour or until slightly firm.
Remove from freezer. Using ice cream scoop, scoop yogurt from bowl, capturing both flavors. Place 1 scoop of swirled yogurt on chocolate side of one granola thin. Place another granola thin on top, chocolate side down. Press together slightly. Wrap individually in foil, and freeze at least 2 hours until firm.
Before serving, let stand 10 minutes at room temperature.
