Make the Dough
In a large bowl, whisk together all the dry ingredients.
4 ⅙ cups all-purpose flour, ¼ cup granulated sugar, 2 tsps yeast - I used rapid rise instant yeast (no blooming required), 1 tsp salt (I used Celtic salt)
Add the egg, yolk, milk, and melted butter, then mix to combine.
1 cup warm milk (not hot) 110℉/43℃, 1 large egg + 1 egg yolk (room temperature), ¼ cup unsalted melted butter
Knead in the bowl for 8–10 minutes until smooth and elastic.
Shape into a ball and cover with a damp kitchen towel, and let rise until doubled (about 1 hour).
Make the Apple Cider Filling
In a saucepan, melt butter over medium heat.
3 tbsps unsalted butter
Add chopped apples, cider, brown sugar, cinnamon, nutmeg, and salt.
2 large apples (peeled and diced small) I used Honeycrisp, ½ cup apple cider/ cloudy apple juice, ¼ cup light brown sugar (packed), 1 tsp ground cinnamon, 1/2 tsp ground nutmeg, a pinch of salt
Cook 10-15 minutes until apples soften and cider reduces to a syrup.
Cool completely.
Brown the Butter
In a small saucepan, melt the butter on medium heat.
2 tbsps unsalted butter (browned)
Turn the heat on low and let the melted butter simmer until it turns golden brown. Stir continuously to avoid burning. It should take about 5-10 minutes.
Once the butter is browned it will start to smell nutty and of caramel.
Let the brown butter cool off completely before using.
Roll and Fill
Once the dough has doubled, place it on a floured surface and roll with a rolling pin into a 35 × 45 cm (14 × 18 in) rectangle.
Brush with browned butter.
Sprinkle evenly with brown sugar + cinnamon.
¼ cup light brown sugar (packed), 2 tsps ground cinnamon
With a pizza cutter or a sharp knife slice it into 8 equal rectangles.
Spread apple cider filling on the middle of each sleeve.
Roll each one tightly, and place in a greased 9×13 in (23×33 cm) dish.
Second Rise
Cover and let rise 30–40 minutes until puffy. Preheat your oven to 175°C / 350°F.
Bake
Bake at 175°C / 350°F for 25–30 minutes, until golden brown.
Icing
Beat cream cheese and butter until smooth.
4 oz cream cheese (softened), 2 tbsps unsalted butter (softened)
Add powdered sugar, vanilla, and milk until creamy. If you prefer a thick icing, use only a small amount of milk (1 tbsp). If you prefer it thinner, use more milk (but add it in gradually)
1 cup powdered sugar/ icing sugar, 1-2 tbsps milk (room temperature), 1 tsp vanilla extract
Spread over warm rolls.
Optional: sprinkle some ground cinnamon on top right before serving.
