Make the Dough: In a large bowl, mix together the flour, sugar, salt, and instant yeast. In a separate bowl, whisk together the warm milk, melted butter, egg, and vanilla extract. Gradually add the wet ingredients to the dry ingredients, mixing until a soft dough forms.
Knead the Dough: Turn the dough out onto a floured surface and knead for about 5-7 minutes until smooth. Place the dough in a greased bowl, cover with a clean kitchen towel, and let it rise in a warm place for about 1 hour, or until doubled in size.
Prepare the Filling: In a small bowl, mix together the chopped pecans, brown sugar, and cinnamon. Set aside.
Assemble the Buns: Once the dough has risen, roll it out into a rectangle (about 12x18 inches) on a floured surface. Brush the dough with melted butter and sprinkle the cinnamon-pecan mixture evenly over it. Roll the dough tightly from the long edge into a log.
Cut the Buns: Slice the log into 1-inch thick rolls and place them in a greased 9x13-inch baking pan. In a separate small bowl, mix the maple syrup and any leftover melted butter. Drizzle this mixture over the buns.
Second Rise: Cover the baking pan with the towel again and allow the buns to rise for another 30 minutes.
Preheat the Oven: Preheat the oven to 350°F (175°C).
Bake the Buns: Bake the sticky buns in the preheated oven for 25-30 minutes, or until golden brown and cooked through. If the tops start to brown too quickly, cover them loosely with aluminum foil.
Cool and Serve: Once out of the oven, let the buns cool in the pan for 5 minutes, then turn them out onto a serving plate so that the sticky syrup spreads over the buns.
Notes
Serve warm, drizzled with extra maple syrup and a sprinkle of chopped pecans on top. For a delightful touch, add a scoop of vanilla ice cream on the side for a decadent treat!
