Ingredients
  

For the Dough
  • 4 cups all-purpose flour
  • 1 cup warm milk
  • 1 packet active dry yeast
  • 3 large eggs
  • ½ cup sugar
  • ½ cup softened butter
  • 1 teaspoon vanilla extract
  • Zest of one lemon
  • Pinch of salt
For the Walnut Filling
  • 2 cups finely ground walnuts
  • ½ cup sugar
  • ½ cup warm milk
  • 2 tablespoons cocoa powder
  • 1 teaspoon vanilla extract
For the Top
  • 1 beaten egg for brushing
Optional: 2 tablespoons crushed walnuts

Method
 

Activate the yeast
  1. Stir warm milk, a spoonful of sugar, and the yeast in a bowl. Let it sit for about 10 minutes until it becomes foamy. If nothing happens, the yeast may be old.
Make the dough
  1. Beat the eggs and sugar until light in color. Add the butter, lemon zest, vanilla, and salt. Pour in the yeast mixture. Add the flour slowly and mix until a soft dough forms. It should feel slightly sticky.
Knead the dough
  1. Knead the dough on a lightly floured counter for 8–10 minutes. The dough should start feeling smooth and stretchy. Place it in a greased bowl, cover it, and let it rise for 1–1.5 hours.
Prepare the filling
  1. Mix the ground walnuts, sugar, warm milk, cocoa powder, and vanilla. The filling should be easy to spread. If it’s too thick, add a splash of warm milk.
Shape the bread
  1. Punch down the dough gently. Divide it into two pieces. Roll each into a rectangle. Spread the filling evenly and roll each one into a tight log. Twist the two logs together and place them in a loaf pan.
Final rise
  1. Cover the loaf pan and let the dough rise again for about 30–40 minutes.
Bake the bread
  1. Brush the top with beaten egg and add crushed walnuts if you want. Bake at 350°F (175°C) for 40–45 minutes or until the top is golden brown.
Cool before slicing
  1. Let the loaf cool fully before cutting so the swirl holds its shape.

Notes

  • Warm milk is important. Too hot and the yeast won’t work.
  • Don’t rush the rising time. The dough needs patience.
  • Slice with a serrated knife once fully cooled so the swirl stays clean.
  • The bread tastes even better the next morning.
