Place one sheet of phyllo dough on a work surface; spritz with butter-flavored spray. Top with another sheet of phyllo; spritz with spray. Cut into six squares. (Keep remaining phyllo covered with plastic wrap to avoid drying out.) Repeat with remaining phyllo.
Stack three squares of layered phullo in each of six muffin cups coated with cooking spray, rotating squares so corners do not overlap. Mix cinnamon with 1/4 tsp of sugar and sprinkle into each cup. Spritz with spray. Bake at 375 degrees F. for 6-8 minutes or until golden brown. Cool on a wire rack.
Meanwhile, in a small bowl, whisk the yogurt, orange peel and juice, and remaining sugar. Spoon yogurt mixture into cups; top with berries; garnish with mint and orange peel.
