Take the flour, baking powder, sugar and salt in a mixing bowl. Mix it and then make a well. Whisk an egg and add to the centre of the well.
Add vanilla, melted butter and 1 cup of milk.
Whisk it well. Add more milk if required to make a smooth batter which should be thick but of pouring consistency.
Divide the batter into different bowls (depending on how many food colours you have).
Add drops of food colour in each bowl and mix them well.
Take two non-stick frying pans. Heat both. When both the frying pans are hot, brush butter on both.
Pour pancake batter in the frying pan to 3-inch diameter. It is faster if you use two frying pans.
Keep the temperature low and let the pancake cook. When bubbles start to form on top, flip the pancakes.
After a few seconds, when the pancakes are cooked, slide them out.
Serve with maple syrup or honey.
