Preheat your pan on medium low flame for 15 - 20 minutes.

If baking in oven, preheat it to 180°C.

In a bowl, combine, peanut butter, sugar, vanilla and egg.

Add in wheat flour and mix to form a soft dough.

Divide it into 8  or 12 equal portions and roll into balls.

Place them 2 cm apart on the tray and use a fork to make criss-cross impressions.

Place it inside the preheated pan and bake for 15-20 minutes.

The cookies would feel soft even after the time, but remove it.

The remaining heat in the cookies will keep on baking the cookies.

Once cool, store in airtight box.
