Made the recipe exactly as said and it was delicious! 
I will only say that it's crucial that the milk and egg be at room temperature. 
I microwaved the milk for a minute to take  the chill out and ran the egg under hot water. (in case you don't want to wait)
Also let the batter stand for a good ten minutes. At first i thought it was too thin but after letting it sit the batter thickened.
