In a bowl, whisk together egg, oil and water until well combined.
Add into the liquid mixture the hotcake mix and half of chocolate chips. Mix together until it forms a dough.
Wrap the dough in a plastic wrap and refrigerate for 10-15 minutes for easy handling of cookie dough.
Preheat a big heavy bottom pot or pan over very low heat. Place a wire rack inside and put the lid on and preheat for 10-15 minutes to contain the heat inside the pan.
Get the chilled dough and measure around 5-7 grams each using a digital weighing scale for a more uniform cookie size then roll into a ball, top each ball of cookie dough with the remaining chocolate chips.
Arrange cookie dough on a lightly greased small tray one inch apart giving enough space for rising.
Place the tray on the preheated pan and put back the lid on. Cook for 5-7 minutes or until golden brown. Do the same procedure until all the cookie dough is consumed. Cool before serving.
To serve, put some cookies on a bowl and pour your favorite fresh milk to make a good bowl of chocolate cookie chip cereal.
