In a bowl, cream together butter and sugar.

Then add the egg and beat well.

Add the rest of the ingredients except the colours and the chocolate chips.

Once they are all mixed, divide the dough into two parts or into as many parts as the number of colours you want.

Then add one colour to one part of the dough and do the same for all the parts. Use as much drops you wants to achieve the desired depth of colour.

Finally add the dark chocolate chips in to the dough.

Please note that this dough is a bit sticky.

Spoon the dough on cookie sheet. You can make individual coloured cookies or mix and match 2 to 3 colours of dough in each cookie.

Bake in a pre heated oven (180 degrees C) for only 8 minutes. Be sure to take them out just at 8 minutes or less if you feel.

They will be soft at this point. Gently pull the cookie sheet out of the tray and place on a wire rack to cool down.

Before the cookies harden, decorate them by pushing some white chocolate chips on the soft cookies. The cookies harden and are ready to serve once they are cooled down completely.

Please note: It’s not necessary to bake all the cookies at once. You can store as much of the cookie dough in batches in the refrigerator for a week- 10 days and in the freezer for 6 months.
