These egg muffins come out the oven all puffed up and gorgeous, but tend to collapse a bit when cooling down. Don't let this deter you - they taste delish all the same.
i made slightly different, used 4 eggs, spring onion, chorizo/salami and prosciutto deli pack and lightly fried in coconut oil. Used protein cheese instead of cheddar. - made 6. Was delish! - 17 Jan 2018
