How to make
Beat the sugar, eggs, oil, honey and soda with a mixer. Add the walnuts and cinnamon. Add the flour and mix everything until a medium soft dough is obtained.
Make balls shapes out of it, arrange them at a distance in a tray lined with baking paper. I have put a walnut in the middle of half of them.
Bake them in a preheated oven at 340°F (170 degrees) until they aquire a golden color. While they're slightly warm, the halves without the walnuts are stick together with prune jam in between them.
The other cookies with walnuts on top are left as they are.
