Sift flour, sugar and salt together into a medium bowl.
In a separate bowl, whisk milk, egg and vanilla together, then add to dry ingredients, whisking until smooth. Set aside and let batter rest for 15-30 minutes.
Heat a non-stick frypan over medium heat and brush with a little melted butter. Drop level tablespoonfuls of the mixture into the pan and immediately sprinkle over a few chocolate chips. Cook for half a minute or until bubbles appear on the surface.
Flip over and cook other side for 30 seconds, or until golden.
Allow to cool and serve plain, or with butter, jam, or peanut butter (whatever you're in the mood for, really!).
