Make the dough: Combine 3 tablespoons flour and 1 teaspoon sugar in a small mixing bowl. Add yeast, then add 1/4 cup warm mix and mix well; let stand until creamy, about 10 minutes.

Beat butter with remaining sugar in a large mixing bowl with an electric mixer until creamy. Add egg yolks, one at a time, beating well after each addition. Add yeast mixture, 1 1/3 cups milk, and salt; mix well.

Add remaining flour, 1/2 cup at a time, mixing well after each addition. When dough has pulled together, turn it out onto a lightly floured surface and knead until smooth and elastic, about 8 minutes.

Lightly oil a large bowl. Place dough into the greased bowl and turn to coat with oil. Cover with a damp cloth and let rise in a warm place until doubled in volume, about 1 hour.

Lightly grease two rimmed baking sheets. Deflate the dough and turn it out onto a lightly floured surface. Divide into two equal pieces. Roll each piece into a rectangle about 1/4 to 1/2 inch thick.

Spread filling ingredients over dough in the following order: melted butter, honey, raisins, and walnuts. Sprinkle cinnamon over top. Roll each piece up and over filling like a jelly roll, pinching the ends to seal. Transfer loaves, seam-side down, to the prepared baking sheets. Let rise until doubled in volume, 45 minutes to 1 hour.

Preheat the oven to 350 degrees F (175 degrees C).

Bake loaves in the preheated oven until golden brown on top, about 1 hour.
