Combine yeast and warm water in a bowl and stir until yeast is completely dissolved. Let this stand for 5 minutes.
Combine milk, egg, butter, and corn syrup into a mixing bowl. Stir to combine.
Stir in the spice blend, salt, and one cup of flour.
Add the yeast mixture to the mixing bowl and stir until it’s well blended.
Add 3 cups of flour, one cup at a time, and mix very well after each cup is added.
Move your dough to a lightly floured surface to blend it further in the next step.
You’ll want to add as much of the remaining cup of flour as is needed as you knead the dough on the floured surface. The dough should be slightly sticky when it’s finished. You’ll know it’s finished kneading when the surface is smooth and only slightly tacky to the touch.
Place the dough in an oiled bowl (or your mixing bowl that’s been rinsed and oiled). Cover with plastic wrap to keep it moist and then cover the plastic wrap with a towel.
Let your dough rise until doubled in volume. This could take as much as 60 to 90 minutes depending on the temperature of your home.
The dough is finished rising when it has doubled in size and a light touch into the dough makes a dent that remains and doesn’t spring back. Now you should divide your dough in half.
Place one half of the dough on a lightly floured rolling surface. Place the remaining dough half portion back into the bowl and cover again with plastic wrap until later.
Roll out your dough until it’s a nice flat rectangle about 1/2 inch thick. Use 2 tablespoons of the butter to spread it over the surface of the flattened dough. Now sprinkle 1/2 cup of brown sugar, 2 teaspoons of the spice blend, and 1/2 cup pecans over the butter.
Roll the dough loosely to a long cylinder.
Slice into 8 roll sections and place into a greased pan. Cover with plastic and a clean towel.
Repeat the rolling and filling process with the remaining half portion of dough.
Allow both pans to rise for 45 minutes or until doubled in size. This could take slightly less time if your home is very warm.
Near the end of the rising time, heat the oven to 350 degrees.
When the oven is heated, remove the plastic and towel. Bake rolls for 20 minutes or until they’re lightly golden on top.
Mix together your powdered sugar, milk, and vanilla extract for a quick and easy glaze. Top the warm spiced sweet rolls with the glaze and serve warm.
