Grandma'S Povitisa (Po-Vuh-Teet-Zuh) Povitica Croatian Nut Bread - cooking recipe

Ingredients

Bread Dough:
1/4 cup warm water
1 (.25 ounce) package active dry yeast
3/4 cup lukewarm milk
1/4 cup white sugar
1/4 cup vegetable shortening (such as Crisco(R))
1 egg, beaten
1 teaspoon salt
3 1/2 cups all-purpose flour, or more as needed
Filling:
1/2 cup brown sugar
1/4 cup butter, softened
1 egg
1/4 cup milk
1/2 teaspoon vanilla extract
1/2 teaspoon lemon extract
2 cups finely chopped walnuts

Preparation

Combine warm water and yeast together in a large bowl. Let stand until yeast softens and begins to form a creamy foam, about 5 minutes.
Stir 3/4 cup lukewarm milk, white sugar, shortening, 1 egg, and salt into yeast mixture. Mix flour into yeast mixture until a soft, easy to handle dough forms.
Turn dough out onto a lightly floured surface and let stand for 10 minutes. Knead dough until smooth and elastic, about 8 minutes. Form dough into a ball.
Place dough in a large, lightly-oiled bowl and turn to coat. Cover bowl with a damp towel and let rise in a warm place until doubled in volume, or until a hole remains when your finger is pressed deeply into the dough, about 2 hours.
Punch down dough and turn onto a lightly floured surface. Shape into ball and let dough rest for 15 minutes.
Beat brown sugar, butter, and 1 egg together in a bowl until creamy. Add 1/4 cup milk, vanilla extract, and lemon extract; stir until smooth. Stir walnuts into the filling mixture until walnuts are completely incorporated.
Roll dough on a large, floured cloth into a 20x30-inch rectangle. Spread walnut filling evenly over the top of the dough, spreading to the edges. Roll the rectangle up along the long edge like a jelly roll and pinch edges to seal. Coil the roll into a snail-shape.
Grease a 9x13x2-inch baking sheet. Place shaped dough on the prepared sheet and let rise until an impression remains when the dough is gently pressed, about 1 hour.
Preheat oven to 325 degrees F (165 degrees C).
Bake in the preheated oven until the top is golden brown, 40 to 45 minutes.
