Preheat oven to 380 degrees F. Cover 2 baking sheets with parchment paper. Beat together butter, brown sugar, granulated sugar and vanilla sugar.
Little by little add sifted flour ,mixed with salt and baking soda.
Add chocolate chips and mix well.
Spoon out the cookie dough using a cookie scoop(use your hand if you don't have cookie spoon) and place on the parchment lined baking sheet. Divide the nuts and seeds on top of the each cookie and gently press down on the dough ball to flatten slightly.
Bake for 8-10 minutes, until the edges are set but the middle is still soft.
Let cool cookies for few minutes then transfer them with a spatula to a rack to cool completely.
Enjoy it with glass of milk or your favorite tea.
