Blend all the ingredients in a blender till smooth. The mixture should be the consistency of a crepe batter so add a splash of water if necessary. Let the batter rest for 15-20 minutes. This helps the oats absorb some of the liquid.
Heat a pan or griddle, and spray or brush with a little oil. Pour half a cup of batter with ladle in the center and spread it with the back of the ladle. Sprinkle a teaspoon of oil around the edges of the dosa and cook till golden brown and crisp. Repeat for the remaining batter. Serve with your favorite chutney.
Notes
Use a non-stick pan or tawa for the best results. You can also use a well seasoned cast iron pan as well.
Donot skip any of the ingredients as it will vastly affect the taste and texture of the batter. Consistency is key to get soft and crispy dosas.
