Preheat oven to 300°F. Spray a 12-cup silicone muffin mold with cooking spray and place in a large roasting pan.
In a blender, combine eggs, cottage cheese, heavy cream, salt, and pepper. Blend until completely smooth, about 60 seconds.
Divide the cooked bacon, spinach, bell pepper, and shredded cheese evenly among the muffin molds.
Pour the egg mixture over the fillings, filling each mold about 3/4 full.
Carefully pour hot water into the roasting pan until it reaches halfway up the sides of the muffin molds.
Bake for 22-25 minutes, until the egg bites are set but still slightly jiggly in the center.
Remove from oven and let cool in the molds for 10 minutes before gently removing. Serve warm or store for later.
