Soft and fluffy cinnamon rolled made with buttery brioche dough and shaped into pastry rings.
In a bowl of a stand mixer, place the flour, yeast, sugar, salt, eggs, and water, and use the paddle attachment to bring it together into a shaggy mass.
Replace the paddle attachment to the dough hook, and with the mixer on medium speed, add the butter one piece at a time. Wait about 15 seconds between each addition.
Mix for 15-20 minutes, until the dough is smooth and does not tear when you gently stretch it.
Spray with cooking oil, cover with plastic wrap, and refrigerate for 10-12 hours.
Place the ingredients in a large bowl and mix until smooth.
Remove dough from the refrigerator, and punch to release the air. Divide into 12 equal pieces (each about 80g/3oz).
Roll each piece over a lightly floured surface into an 8x6-inch rectangle.
Spread with one tablespoon of cinnamon filling.
Roll the top and bottom wide side towards the center.
Hold the ends of the pastry and twist it 3-4 times, and bring the ends together to form a ring shape.
Pinch the ends, and place the pastry over a baking sheet lined with parchment paper. Brush with egg, and let rest for 2-3 hours.
Bake at 350F (180C) for 20 minutes, until golden brown, until the inner temperature is 180F (80C).
Bring the water and sugar to a boil while the pastries are baking.
Remove from the oven, brush with simple syrup, and serve.
