In a large mixer bowl, combine water, buttermilk, sugar, melted butter & yeast, stir & then allow to sit approx 15 minutes for yeast to proof. (you know it's ready when it's puffed & frothy)
Add in eggs, salt & flour & mix together slowly using a dough hook until flour is incorporated
Mix/knead 10 minutes
Once mixed, let rest 10 minutes while you make your filling & preheat the oven
Prepare the filling by combining melted butter, brown sugar, sugar & cinnamon in a small bowl & mixing with a fork
Prepare the topping by melting brown sugar, butter & honey in a saucepan.
Remove from heat & add in pecans & bacon
Pour into the bottom of your prepared pan
Preheat oven to 375 degrees & line a 9x13 pan with parchment
Roll dough out on lightly floured surface into a flat & even layer (approx 12x15)
Sprinkle filling mixture on top
Roll tightly on the long side & then cut into 12 large rolls (easiest way to make them even is to first cut the log in half & then cut those two pieces in half again & then those 4 pieces into thirds)
Place in prepared pan on top of your gooey topping & bake 20-25 minutes
Add melted butter, caramel sauce & more bacon for topping when serving if desired
