1 large egg
3/4 cup nutella + extra for the filling
1/4 cup broken walnut pieces or any other nut of your choice

• Preheat oven to 180 degree celsius.
• Using a tablespoon, scoop our the dough and form around 20 - 25 balls. Place the cookies on the baking sheet.
• Using your finger tip or the back of a wooden spoon make a dent in the center of each cookie ball.
• Fill each dent of the cookie with a little nutella and stick the walnut piece into it.
• Bake these cookies for about 10 minutes.
• Take the cookies out of the oven and let them cool down on the baking sheet for 10 minutes, then transfer to a cooling rack and allow them to cool completely.
• Store the cooled cookies in an airtight container. 

*Be careful while measuring the flour, fill themeasuring cup with the flour rather than scooping the flour.

* Don't leave the cookie dough for more than the specified time in the refrigerator as this will cause the dough to crack while forming the balls.

*The easiest way of filling the cookies with nutella is using a piping bag or a zip lock bag. Fill a zip lock bag with the nutella and cut the tip and use it to fill the cookies.

* These cookies will remain fresh for upto one week if stored in an air tight container.
