Make a brioche dough: 

1. Combine flour, sugar and yeast in a bowl of a stand mixer. Blend for 1 min. Mix in a small bowl, eggs and 1/2 cup milk pour into the flour mixture, using dough paddle hook, mix until dough forms.
2. With the mixer on low speed, add butter, a spoonful at a time and then salt. Add 2 tablespoons of milk. Mix dough on medium speed for 4 minutes until smooth.
3. Spray a bowl with oil and return the dough to the bowl, turning it to coat with oil. Cover with plastic wrap and let rise until doubled, 1 – 1 1/2 hours. (At home, you can leave it in fridge overnight).

Make the filling:

1. Melt the chocolate and butter by using the microwave or bain-marie method. Add the mixture and mix well until smooth. Refrigerate until use.

To assemble:

1. Coat two 9-by-4-inch loaf pans with oil or butter. line the bottom of the pan or ring with a parchment paper.
2. Divide into 2 pieces. Roll out each piece on a well-floured parchment paper. Each piece should be about 10-inch wide and 1/4 inch thick.
   Spread chocolate mixture evenly over the dough, spread chocolate, coconut, and cinnamon.
3. Roll the dough up with the filling into a log. Gently cut each log into half lengthwise, with a sharp knife into two halves. Cut sides up, next to each other. Form a twist, keep the cut sides facing up. See the demo.
4. Roll the twist into a round circle and transfer the dough to the prepared pan. Spray with an oil spray, cover with a plastic wrap and let it rise for another 1/2 hour, room temperature.
5. Preheat oven to 375°F (190°C). At home; place a dish filled with boiling water at the bottom of the oven.
   Brush babkas with egg wash. Bake for 30-40 minutes, until golden brown.
6. While babkas are baking, make the syrup: Bring sugar and water to a simmer until sugar dissolves. Remove the babkas from the oven, brush the syrup all over. Let it cool on a rack.
