In the bowl of a stand mixer, combine active sourdough starter, water, flour, baking soda, baking powder, salt, butter, maple syrup, and eggs. Mix together until smooth, glossy, about 10 minutes at low speed. You will know when it’s ready when the dough is translucent and elastic - when placing a ball in your hands you should be able to pull it and light should go through before it breaks.
½ cup active sourdough starter, ½ cup water, 4 ½ cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, ½ teaspoon salt, ½ cup melted butter, ½ cup maple syrup, 2 eggs
Place the dough in a greased bowl and cover. Allow to rest in a warm place overnight.
In a separate bowl, combine all the filling ingredients.
½ cup butter, 1 cup brown sugar, 2 tablespoons cinnamon
Lightly dust the counter with flour, and roll out the dough into a ¼ inch thick rectangle.
Add butter and cinnamon-sugar filling to the top of the dough and spread evenly. Roll the dough up as tightly as you can. Slice to make 12 even rolls.
Place the rolls in the air fryer basket covered with parchment paper.
Bake in the air fryer at 160ºC (320°F) for 12-15 minutes or until the rolls are lightly browned and the dough is cooked through. Allow them to cool in a rack.
Mix all the cream cheese topping ingredients and spread over the rolls.
6 ounces cream cheese, ½ cup heavy cream, 1 cup confectioner’s sugar, 2 teaspoons vanilla extract
Sprinkle a bit of cinnamon just before serving.
