– Add melted butter, flour, sugar, vanilla, cardamom, and ground walnuts to a bowl.
Prepare Filling
Mix thoroughly until the filling ingredients are combined and crumbly.
Remove dough from refrigerator; divide into 4 equal portions. Roll out one portion at a time into a 10" x 6” rectangle. Brush with melted butter.
Spread ¼ of the filling over each rectangle. Cover with parchment paper and lightly roll over it with a rolling pin so that the filling adheres to the dough.
– Fold the edges in ½” over the filling and roll into a cylinder. Gently flatten the cylinder with your palms.
Cut each roll into 9 pieces and arrange on a parchment-covered cookie sheet. Prick a few times with a fork.
– Whisk egg yolk and yogurt together to make the glaze. Brush Nazook liberally with the glaze and bake for 30 minutes, or until golden brown.
