Mix all the dry ingredients (bread flour, instant yeast, sugar, salt) in the bowl of the stand mixer.
Add the ricotta cheese, egg and water.
Start to knead the dough at a low setting (speed 2). Once all the dry ingredients come together, add the room temperature butter.
Note: More water or flour may be needed depending on the protein content of the flour, the water content in the ricotta cheese, as well as the humidity and temperature of the kitchen. If adding additional water or flour, be sure to add one tablespoon at a time, just until the dry ingredients are no longer visible.
Continue to knead for about 8 to 10 minutes, or until the dough pulls away from the bowl and forms a slightly sticky, but still a stretchy-supple dough.
Remove the finished dough from the mixer bowl and place in a lightly greased bowl.
Let rise until doubled, about 60-90 minutes**
While the dough rises, prepare the filling by preparing the filling ingredients (either the custard or sugar filling NOT both). Set aside.
When the dough is ready, punch down the dough then remove from bowl. Place on a generously floured surface and use a rolling pin to flatten the dough into a rectangle, about 18 x 10 inches in size.
Spread the filling mixture evenly over the dough
Starting from the end, shape the dough into a roll. Pinch the seams to seal.
Use a string or dental floss to cut the rolled up dough into individual rolls. Note: For wider, dome-shaped rolls like the ones in the photos, cut log into 16 rolls and arrange them 1 inch apart on a half-sized (8"x13") sheet pan. For regular tall cinnamon rolls with straight sides, divide into 12 rolls and use a 9" x 12" rectangular pan or a quarter sheet pan, and space them half-inch apart so that they're almost touching. Line the baking pan with parchment paper. A well-greased pan will also work.
Place the individual rolls on a parchment-lined baking pan, swirl side up, and about ¾ inches apart
Let the rolls rise again for about 30 minutes until puffy. Toward the end of the rise time, preheat the oven to 350F / 180C
Bake the rolls for 15-20 minutes until golden brown
Use a sieve to dust powdered sugar on top. Alternatively, top with a scoop of ricotta cheese, a sprinkle of pistachio nuts. Drizzle with honey.
Enjoy!
