Preheat the oven to 350°F. Separate the wontons and place one into each cavity, pressing them down until they form a cup. Use four fingers to fit them to the sides of each muffin cavity. Spray each wonton with cooking spray (or brush with melted butter). Bake for 8-10 minutes or until lightly browned. Remove the wontons from the oven and leave them in the muffin pans. Keep the oven temperature at 350°F for the next step.
Mix the cream cheese, sour cream, onion powder, Worcestershire, garlic powder, sugar, cayenne, pepper, and salt with a mixer until smooth. (If the cream cheese is very soft, you can mix it by hand.) Stir in the jalapeno and cheese and mix well.
Divide the cream cheese mixture between the wontons. Bake for 8-10 minutes or until the cheese melts. If the wonton cups start to overbrown, place a sheet of aluminum foil over them.
Garnish with green onion. Serve with sweet and sour sauce.
You can find wonton wrappers in the produce section of grocery stores.
Baked Wonton Shells
Store baked shells in an airtight container on the countertop for a few days or in the freezer for 2-3 months.
Unused Wontons
Wrap unused wontons in plastic wrap (or put them in a small resealable plastic bag) and place them in an airtight container. Store them in the freezer for 2-3 months. Thaw them in the microwave on defrost for a few seconds to separate them, or let them thaw on the countertop until they are soft and pliable.
Muffin Pans
This recipe uses regular-sized muffin pans, not mini muffin pans.
Storage and Reheating
Store wonton cups in the refrigerator. To reheat, cover them with aluminum foil and heat them at 325 degrees F for 15 minutes or until the shells are crispy and the filling is warm.
