I never thought that roti kok is so easy to make at home. After watching it on TV, I tried making it. It is indeed easy. All you need are bread, butter, and sugar. Then bake it in the oven (170 degree Celsius, 15-17 minutes, no flipping needed) or air fryer (160 degree Celsius, 13-15 minutes, flip it mid-cycle). As simple as that.
Once done, leave it to cool then store in an airtight container. Have fun trying!
