Step 1

Place the flour, sugar, yeast, salt, and eggs in a bowl of a standing mixer.

Step 2

Using the paddle attachment, mix the ingredients on low while you drizzle in the milk.

Step 3

Mix until you have a shaggy mass, then replace with the dough hook.

Step 4

Mix at medium-low speed for 2-3 minutes. You should have a ball of dough that is not smooth and slightly dry.

Step 5

Increase speed to medium, then add the butter, one piece at a time, waiting for the butter to be incorporated before adding the next piece.

Step 6

Mix the dough until the butter is fully incorporated, the dough is smooth, and the sides and bottom of the bowl are clean.

Step 7

Cover the bowl with plastic wrap and place it in a warm spot to double in size, about 90 minutes.

Step 8

Mix all of the ingredients until smooth. You can use a hand mixer or a stand mixer.

Step 9

Divide the dough into two equal parts. Roll each part over a clean work surface dusted with flour into a 19x13-inch rectangle.

Step 10

Spread half of the chocolate filling over the dough, leaving a one-inch border around the edges.

Step 11

Gently lift the wider side of the rectangle and fold it in half.

Step 12

Gently roll the rectangle into a 19x8 rectangle.

Step 13

Using a sharp knife or a pizza wheel, mark the dough every two inches along both wide sides.

Step 14

Cut the dough diagonally from the first mark closest to you, moving toward the opposite corner and back in a straight line.

Step 15

Gently roll each triangle from the wide end toward the tip, stretching the dough with your opposite thumb.

Step 16

Place the pastries over a baking pan lined with parchment paper.

Step 17

Brush the pastries with an egg wash and place in a warm spot to rise for 60-90 minutes.

Step 18

As the pastries rest, make the simple syrup by bringing the water and sugar to a boil, then reduce to a simmer and cook for five minutes.

Step 19

Bake for 20-25 minutes, at 350F (180C) preheated oven, or until a thermometer reads 180F from the center of the pastries.

Step 20

Remove from the oven and brush with the simple syrup.
