01 -  Preheat the oven to 350°F (175°C). Lightly grease a 12-cup muffin tin or line it with silicone muffin liners. 
 02 -  In a large mixing bowl, whisk together eggs, milk, buffalo sauce, ranch dressing, cream cheese, garlic powder, onion powder, salt, and black pepper until homogenous. 
 03 -  Fold in shredded cheddar cheese, green onions, red bell pepper, and, if desired, the cooked shredded chicken. 
 04 -  Evenly distribute the mixture among the muffin cups, filling each approximately three-quarters full. 
 05 -  Place the muffin tin in the oven and bake for 18–22 minutes, until the centers are set and the tops appear lightly golden. 
 06 -  Remove from oven and allow egg bites to cool for 5 minutes. Run a small knife around the edges of each cup to release. Serve warm or at room temperature.
