In a large bowl, combine the shredded chicken, buffalo wing sauce, cheddar cheese, mozzarella cheese, cream cheese, green onions, and ranch dressing. Mix well until all ingredients are evenly incorporated. Season with salt and pepper to taste.
Assemble the Blasts:
Lay a wonton wrapper on a clean surface. Place about one tablespoon of the filling in the center of the wrapper.
Dip your finger in water and moisten the edges of the wrapper. Fold the wrapper in half diagonally to form a triangle, pressing the edges firmly to seal.
Repeat with the remaining wrappers and filling.
Fry the Blasts:
Heat vegetable oil in a deep fryer or large pot to 350°F (175°C).
Carefully add a few of the prepared wontons to the hot oil, being careful not to overcrowd the pot. Fry until golden brown and crispy, about 2-3 minutes per side.
Remove the blasts from the oil and drain on paper towels. Repeat with the remaining wontons.
Serve:
Arrange the Buffalo Chicken Blasts on a serving platter. Drizzle with additional buffalo wing sauce if desired.
Serve with ranch or blue cheese dressing for dipping.
