Preheat oven to 375°F and grease a 9x13 inch pan or cast iron skillet.
In a large bowl, whisk flour, baking soda, baking powder, and salt.
Add sourdough discard, water, cooled butter, and honey. Stir into a soft dough (3-5 minutes).
Roll dough into a ¼-inch thick rectangle on a floured surface.
Mix filling ingredients and spread evenly over dough.
Roll tightly into a log, slice into 12 pieces, and place in the pan.
Bake 25-35 minutes until golden.
While baking, warm cream cheese, heavy cream, honey, and vanilla until smooth.
Cool rolls 5 minutes, then pour warm topping over them. Serve immediately.
