Combine warm milk, sugar, and yeast together. Let rest for 5 minutes until the yeast is bubbly.
1 cup milk, 2 ¼ teaspoons active dry yeast, 3 tablespoons granulated sugar
Place in a large mixing bowl along with eggs, butter, salt, and 1 cup of flour. Mix to combine.
3 eggs, ½ cup butter, 1 teaspoon salt, 4 ¾ - 5 ¼ cup flour
Add remaining flour ½ cup at a time until the dough forms a ball. (You might not need all the flour.)
Knead for 5-7 minutes until the dough is soft and pillowy.
Form into a ball and place in a lightly greased bowl. Cover and let rise until doubled, about 1 - 1 ½ hours.
Pecan Glaze
While the dough is rising, make the pecan glaze. Place butter, brown sugar, maple syrup, and salt in a saute pan. Cook over medium heat, stirring often until it comes to a boil. Boil for 30 seconds. Remove from heat and stir in vanilla.
4 tablespoons butter, ½ cup brown sugar, ½ cup maple syrup, 2 teaspoons vanilla, ⅛ teaspoon salt
Pour into a buttered 9x13 inch baking dish. Sprinkle pecans evenly over the glaze.
1 ½ cups pecans
Filling
Make filling by combining melted butter, brown sugar, and cinnamon.
2 teaspoons ground cinnamon, 4 tablespoons butter, ½ cup brown sugar
Assembling the Buns
Roll out the dough into a large 12x18 inch rectangle. Spread with filling.
Roll up into a round log. Pinch seams. Slice into 12 pieces.
Place sliced cinnamon rolls on top of pecans. Cover and let rise for 30-45 minutes until puffy.
Bake in preheated 350°F oven for 28-35 minutes.
Allow the buns to cool for 5 minutes. Then place a cookie sheet with a piece of parchment paper over the top of the pan and carefully flip over. Use caution when flipping, the caramel filling is very hot.
Rising time will vary depending on the temperature of your kitchen.
Use caution when flipping the sticky buns. You need to flip while the caramel is still hot, but you don't want any to drip onto you. Place a cookie sheet over the top of the pan. Use hot pads to hold the baking pan firmly against the cookie sheet. Use a quick motion to flip.
Store fully cooled sticky buns in an airtight container at room temperature.
