Preheat the oven to 350°F and lightly coat a muffin tin with cooking spray.
Press one wonton wrapper into each muffin cup, making sure it forms a little bowl shape.
In a bowl, mix together spinach, artichokes, cream cheese, sour cream, mozzarella, parmesan, garlic, salt, and pepper until well combined.
Spoon the filling into each wonton wrapper, dividing it evenly.
Bake for 12-15 minutes or until the edges are golden and the filling is hot and bubbly.
Let them cool for a few minutes before serving.
