Sift in dry ingredients in a bowl and mix well with a whisk. Beat an egg in a different bowl, add milk, and mix well.

Add the dry ingredients 1/3 at a time, and mix just until blended. Add cooking oil and mix again.

Cover with plastic wrap and leave to set for 5 minutes. Meanwhile, heat a non-stick frying pan over medium heat. Place the pan on a wet towel to cool down the pan a little bit.

Turn the heat down to low, place the pan, pour about 1/2 ladle of the batter onto the pan, and cook until bubbles appear on the surface. Flip with a spatula, then cook for a minute until browned on the other side. Repeat the steps to complete the rest.

Place a piece of butter on top and pour some maple syrup.
