In a bowl add the banana and jaggery.
Mash it with the helpf of a forlk, so that jaggery is almost dissolved in banana.
If using Egg, add it now and whisk it along with a banana.
Now add wheat flour, baking powder and salt and mix.
Slowly add the milk and make it into a semi-thick consistency batter.
Let the batter rest for 5 minutes.
Heat a non-stick pan or a cast iron tava/griddle.
Add a teaspoon of batter and spread it.
Now pour 2-3 tablespoon of batter or as desired.
To make thick pancakes just pour the batter and let the batter takes its shape. A proper consistency batter will take its shape on its own.
If you want crepes, pour 2 tablespoons of batter and with the back of a spoon spread it in the form of a circle or like we do for dosa.
Let the pancakes or crepes cook on medium for 2-3 minutes.
Once the top looks cooked, i.e. the batter is almost dried and the pancake leaving its edges, flip and cook on the other side.
Cook it until done on both sides.
