In a saucepan, melt together the chocolate bar and butter. Then leave it aside until cooled.
When your chocolate is fully cooled, preheat the oven at 180°C (350°F). In a large bowl, mix together the sugar and the eggs, until pale. Then add the vanilla sugar.
Now that everything is mixed, add the melted chocolate and mix.
Then carefully add the flour, and the chocolate chips. You will have more of a brownie texture, not a cookie one.
Your mixture is now ready, prepare your baking sheet. You won’t be able to form little balls so use spoons, and form circles. (the space between them should be 4-5cm) Then you can play by adding almonds, other desired nuts or even more chocolate on top. Now put in the oven for 10-12 min, they should have a nice crust on top!
