Line a muffin baking tray with silicone liners or else spray each muffin tin with coconut oil.
Line each muffin liner with a slice of ham. In a pouring jug, whisk together the eggs and cream with a fork. Pour evenly between the ham-lined muffin tins.
Top each ham and egg cup with some cheese.
Bake in preheated oven for 15 - 20 minutes, or until done.
