Preheat your oven to 350F (175C). Grease a baking dish with butter or cooking spray.

In a bowl, combine the finely chopped walnuts, ground cinnamon, and ground cloves (if using). Mix well to create the flavorful walnut filling.

Lay a sheet of phyllo dough in the greased baking dish and brush it with melted butter.

Continue layering: Add another sheet of phyllo dough on top and brush with melted butter. Repeat until half of the phyllo dough is used.

Sprinkle half of the walnut mixture evenly over the layered phyllo.

Layer and butter the remaining phyllo sheets on top of the walnut mixture, brushing each sheet with melted butter.

Sprinkle the remaining walnut mixture over the top layer.

With a sharp knife, cut the baklava into small diamond or square shapes.

Bake in the preheated oven for about 45-50 minutes, until golden brown.

In a saucepan, combine the granulated sugar, water, honey, and lemon juice. Bring to a boil, then reduce heat and simmer for about 10 minutes until slightly thickened.

Once out of the oven, immediately pour the prepared syrup evenly over the hot baklava, allowing it to soak in.

Allow the baklava to cool completely in the baking dish to enhance the flavor.

Once cooled, carefully remove the pieces from the dish and serve.
