This one's quite simple..
Take equal quantities of urad dal and oats. Soak the urad dal for atleast 1/2 an hour. Grind it to a thick paste with some water.
Dry roast the oats and grind along with some curry leaves, jeera into the urad dal paste.
Add salt to taste, and cook like a normal uttapam! My 18 month old baby Sana has it too!
