Vasilopita (Orange Sweet Bread) - cooking recipe

Ingredients

1/2 cup orange juice
1/2 cup water
1 tablespoon ground cinnamon
3 (.25 ounce) packages rapid-rise yeast
2 cups white sugar
1 cup unsalted margarine (such as Fleischmann's(R)), melted
4 eggs
1 orange, zested
7 cups bread flour, or more as needed
1 tablespoon salt
1 tablespoon baking powder
2 coins wrapped in aluminum foil
1 egg white
1 teaspoon vanilla extract

Preparation

Mix orange juice, water, and cinnamon in a microwave-safe bowl. Heat in the microwave until the mixture registers 110 degrees F (43 degrees C) on an instant-read thermometer, 1 to 2 minutes.
Stir yeast into the orange juice mixture. Let stand until yeast is creamy and frothy, about 45 minutes.
Combine sugar and margarine in the bowl of a stand mixer. Beat until creamy. Add eggs; beat on high speed for 30 seconds. Mix in yeast mixture and orange zest until well combined.
Sift flour, salt, and baking powder together in a bowl. Add gradually to the mixture in the stand mixer, mixing with a bread hook until a soft, sticky dough forms, about 5 minutes.
Transfer dough to a large glass bowl. Cover with plastic wrap; let rise in a warm place until doubled in size, 2 to 4 hours.
Preheat oven to 350 degrees F (175 degrees C). Grease 2 round cake pans.
Divide dough into 2 equal pieces. Put 1 wrapped coin in each piece; knead for 2 to 3 minutes and shape into a ball. Place 1 ball of dough in each cake pan. Cover with plastic wrap; let rise until puffy, 2 to 4 hours more.
Whisk egg white and vanilla together in a small bowl. Brush over the top of dough.
Bake in the preheated oven until a knife inserted into the center comes out with a few crumbs attached, 30 to 55 minutes.
