In a small bowl, combine the blueberries, sugar, and lemon juice. Gently mash the blueberries with a fork to release some juices and set aside.
In another bowl, mix the softened cream cheese, vanilla extract, honey, and cinnamon until smooth and well combined.
Spread a generous layer of the cream cheese mixture over half of each tortilla.
Spoon the blueberry mixture over the cream cheese on each tortilla. If using, sprinkle shredded coconut on top.
Fold each tortilla in half to create a quesadilla.
Heat a large skillet over medium heat and add the butter. Once melted, place the quesadillas in the skillet, cooking in batches if necessary.
Cook for about 3-4 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 drizzled on top.
