Cook the chicken breast by baking it in the oven or poaching it until fully cooked. Once cooked, shred the chicken and place it in a bowl.
In the same bowl, mix the shredded chicken with the hot sauce and softened cream cheese until well combined.
Preheat the oven to 350°F (175°C). Spray a mini muffin tin with olive oil.
Place one wonton wrapper in each muffin tin cup. Press the wrapper gently into the cup to create a small well.
Spoon a heaping teaspoon of the buffalo chicken mixture into each wonton wrapper.
Top each filled wonton with crumbled blue cheese (alternatively, you can mix the blue cheese crumbles in with the filling).
Bake in the preheated oven for 18-20 minutes or until the edges of the wonton wrappers are golden brown.
Remove from the oven and let them cool slightly before serving. Serve warm and enjoy!
