In a small pan, whisk together the flour, milk and water. Over medium-high heat the mixture and stir until the mixture thickens up, about 1-2 minutes. Remove from heat and allow it to cool for about 10 minutes in the fridge.
Add flour, brown sugar, yeast, salt, and cinnamon to the bowl of a stand mixer. Whisk everything.
Create a well in the center, and add warm milk, melted butter and Tangzhong. Mix until incorporated. Cover with a towel and let it sit for about 10 minutes to rest.
Knead the dough for 15 minutes on medium speed. If the dough is sticky, add 2 tablespoons of flour while kneading for about 5 minutes.
Lightly grease the bowl with oil and place the dough back. Cover with a kitchen towel and let it sit for 60- 90 minutes in a warm place, or 8-12 hours in the fridge (overnight for these hours is fine too). The dough should rise and double in size.
Roll out the dough to a 12-inch x 12-inch square on a floured surface using the rolling pin.
In a bowl mix together ingredients for the filling.
Spread the filling over the top of the dough. Roll the dough tightly over into a tight log. Cut the dough into 8 pieces.
Add 1/4 cup melted butter into a 13x9-inch baking dish. Place cinnamon rolls into the dish and let rise for about 40 minutes. At the end of the rising time, begin preheating the oven to 350ºF.
In a bowl, add vegan eggs replacer, coconut milk, cinnamon, and vanilla until well mixed.
Pour the mixture over the rolls. (The unbaked cinnamon rolls are baked with the custard, rather than baking them separately.)
Pour 1/2 cup maple syrup over the rolls.
Sprinkle with chopped pecans.
Bake for about 30 minutes or until golden brown.
Pour the remaining 1/4 cup of maple syrup over the rolls.
Mix ingredients for the glaze. Sprinkle over the rolls.
