Preheat the oven to 350 degrees.
Prepare the filling by combining the ricotta, vanilla and powdered sugar. Mix well and place into the fridge for about 20 minutes.
Grease a mini muffin tin and place a wonton wrapper inside each tin, forming the wrappers into cups. They don't have to be perfect; this is what gives them their fun look!
Spray each wrapper with cooking spray or olive oil and bake for 8-10 minutes at 350 degrees.
Allow the wonton wrapper cups to cool for 10 minutes before filling each cup with the cannoli filling. Top each cup with mini chocolate chips and sprinkle with more powdered sugar.
Keep the cannoli wonton cups in the refrigerator until ready to serve.
