Add the butter to the milk and warm in a microwave until it reaches body temperature (between 37 degrees- 43 degrees). It should feel as hot as your finger when you test it.
In the bowl of a stand mixer, add the flour, sugar, and yeast and mix with a spoon.
Using the dough hook start the machine and slowly add the milk mix, the egg, and the salt.
Mix on low for 2 minutes.
Increase the speed to high and continue mixing for 5 minutes.
Scrape out the dough and place it on a floured surface then shape into a ball.
Let it rest for 2 hours in a clean bowl (covered with a cloth) where it will double in size.
2 hours later, preheat the oven and take the dough out of the bowl, it should be 2 or 2.5 times the size.
Dust a clean surface with flour and roll out the dough into a large rectangle (vertically positioned)
Divide the rectangle visually into the top third, middle third, and bottom third and spread the chocolat spread in the middle part.
Fold the bottom third and spread chocolate on the fold.
Fold the top part and roll back into a large rectangle like the one you made at the beginning.
Using a pizza cutter, cut in 9 long thin strips.
Fold each strip into a double knot and tuck the loose ends under, trying to keep the chocolat parts exposed.
Bake for 15 minutes in a preheated oven and share with people you love.
