Melt in your mouth Walnut cookies with Chocolate Truffles

Bake super tasty walnut cookies - a delicious shortcrust pastry, a simple cookie recipe even for Beginners!
Baking cookies couldn’t be quicker or easier: My recipe for delicious walnut cookies works with a little trick and without cutting out. The cookie dough is simply rolled in little balls, placed in your hand and pressed with 3 fingers to make grooves. Awesome right? That works really well. Of course, the cookies taste really delicious and look really good, and if you like, confectioner sugar sprinkled on top!
