Preheat the oven to 375F degrees and spray a muffin tin pan with cooking spray.
Crack the eggs into a medium-sized mixing bowl and whisk well. Whisk in the milk and season the eggs with salt and pepper.
Chop up the steamed broccoli, and divide the broccoli and cheddar cheese evenly between the muffin cups, but do not overfill. Fill about ⅓ of the way full.
Pour the egg mixture about ¾ of the way full into each muffin cup. There should be just enough for 12.
Bake in the middle rack of the oven for 20-25 minutes until the center of the quiches is firm and the edges are golden.
Remove and let cool for a few minutes. Run a butter knife along the edge of each egg bite cup to loosen it from the pan. Lift each quiche cup out of the pan, plate, serve warm, and ENJOY!
