2. Slowly pour the milk while stirring the mixture. Add a dash of cinnamon powder into the mixture.
5. Crack the egg and pour the yolk. Leave out as much egg white as possible as you don't want your croque madame to overflow with egg.
6. Add some cheese on top, depending on your preference. I like to use mozzarella cheese for most of my baking.
7. Heat it to 180 c" (356 F) for 15 minutes. If you don't like your eggs to be runny, you can put it in for about 3 more minutes. I added some almonds (against conventional rule) for that crispy snacking taste.
