Prepare the Dough:

In a large mixing bowl, combine flour, sugar, yeast, and salt.

Add warm milk, eggs, and melted butter to the dry ingredients.

Knead until smooth and elastic (you can use a stand mixer with a dough hook for this step).

Cover the dough and let it rise for 1 hour or until it doubles in size.

Prepare the Filling:

In a separate bowl, combine walnuts, pistachios, sugar, and cinnamon.

Stir until the nuts are evenly coated in the sugar and cinnamon mixture.

Assemble the Buns:

Preheat the oven to 350°F (175°C) and grease a baking pan.

Roll out the dough into a large rectangle on a lightly floured surface.

Brush the dough with melted butter, then evenly spread the nut filling over the entire surface.

Carefully roll the dough into a tight log, then cut it into strips (about 1 inch wide).

Twist each strip and coil it into a bun, placing them into the prepared pan.

Let the Buns Rise:

Cover the buns and let them rise for 30 minutes.

Bake:

Bake the buns at 350°F for 25-30 minutes, or until golden brown on top.

Prepare the Syrup:

In a small saucepan, combine honey, water, and vanilla extract.

Heat over low heat until the honey dissolves completely, stirring occasionally.

Soak the Buns:

Once the buns are done baking, remove them from the oven and pour the honey syrup evenly over the warm buns.

Let the buns soak up the syrup before serving.
