In a large mixing bowl, combine 1 cup of flour, granulated sugar, yeast, and salt. Mix well to combine.
In a separate bowl, whisk together the warmed milk, melted butter, eggs, and vanilla extract.
Pour the milk mixture into the flour mixture and stir until well combined.
Gradually add the remaining flour, 1/2 cup at a time, until a dough forms. Knead the dough on a floured surface for about 6-8 minutes until it's smooth and elastic.
Place the dough in a lightly greased bowl, cover with a clean towel, and let it rise in a warm place for about 1 hour, or until doubled in size.
In a small bowl, mix together the brown sugar, chopped pecans, maple syrup, ground cinnamon, and nutmeg. Set aside.
Once the dough has risen, punch it down and roll it out on a floured surface into a rectangle (about 12 x 18 inches).
Spread the remaining tablespoon of butter over the rolled dough, then evenly sprinkle the maple pecan mixture on top.
Starting from one long side, roll the dough tightly into a log. Cut the log into 12 equal pieces.
Grease a 9x13 inch baking dish and pour any remaining maple syrup mixture in the bottom, then place the buns cut side up in the dish.
Cover the dish with a towel and let the buns rise for another 30 minutes.
Preheat the oven to 350°F (175°C). Bake the sticky buns for 25-30 minutes, or until golden brown.
Remove from the oven and let them cool in the pan for about 10 minutes, then invert the pan onto a serving platter to release the buns onto the platter.
Notes
Drizzle some extra maple syrup over the warm buns and sprinkle with additional chopped pecans for a beautiful finish. Serve warm with a side of cream cheese frosting for an extra indulgent treat!
