In a small bowl, combine the fresh blueberries, honey, and cinnamon. Gently mash the blueberries with a fork to release some juice and mix well.
In another bowl, mix the softened cream cheese, vanilla extract, and powdered sugar (if using) until smooth and creamy.
Heat a large skillet over medium heat and lightly coat it with cooking spray or butter.
Spread a layer of the cream cheese mixture on half of each tortilla.
Spoon the blueberry mixture over the cream cheese layer on each tortilla.
Fold each tortilla in half to create a quesadilla.
Place the quesadilla in the heated skillet and cook for about 2-3 minutes on each side, or until golden brown and crispy.
Remove from the skillet and let cool for a minute before slicing into wedges.
Serve warm with maple syrup if desired.
