2
In the bowl of a standing mixer, whisk together the eggs, buttermilk, granulated sugar, salt, and instant yeast until combined.
3
Add about 2 cups of flour and the melted butter; stir with a wooden spoon or rubber spatula until the mixture is evenly moistened.
4
Incorporate the remaining flour (reserving about 1/4 cup for kneading) and knead with a dough hook on low speed for about 5 minutes, checking the consistency. The dough should feel soft and moist but not wet; add extra flour as needed.
5
Knead for another 5 minutes, until the dough clears the sides of the bowl but still sticks to the bottom.
6
Transfer the dough to a floured surface and knead by hand for about 1 minute to ensure uniformity. The dough should not stick during this process; if it does, incorporate additional flour a tablespoon at a time.
7
Lightly spray a large bowl or plastic container with nonstick cooking spray and place the dough in it. Spray the top of the dough lightly, cover tightly with plastic wrap, and set in a warm, draft-free spot until doubled in size, about 2 to 2.5 hours.
9
In a small saucepan, combine the glaze ingredients: unsalted butter, light brown sugar, corn syrup, heavy cream, and a pinch of salt. Cook over medium heat, whisking occasionally, until the butter is melted and the mixture is completely combined.
10
Pour the glaze into a nonstick 13 by 9-inch baking dish, using a rubber spatula to ensure it covers the bottom evenly. Set the dish aside.
11
To Assemble and Bake the Buns:
12
In a small bowl, combine the filling ingredients: light brown sugar, ground cinnamon, ground cloves, and a pinch of salt. Mix thoroughly, breaking up any lumps with your fingers; set aside.
13
Turn the risen dough onto a lightly floured surface, shaping it into a rough rectangle with the long side facing you.
14
Roll the dough into a 16 by 12-inch rectangle, lightly flouring it to prevent sticking. Brush the surface of the dough with 1 tablespoon of melted butter, leaving a 1/2-inch border along the top edge. Brush the sides of the baking dish with the remaining melted butter.
15
Evenly sprinkle the filling mixture over the dough, again leaving a 3/4-inch border along the top edge, and gently press it into the dough.
16
Starting from the long edge nearest you, roll the dough into a tight cylinder, pinching the seam to seal it. Stretch the cylinder to an even thickness, about 18 inches in length, and push in the ends to maintain an even diameter.
17
Using a serrated knife, slice the cylinder in half, then each half into quarters, creating 12 evenly sized buns (end pieces may be smaller).
18
Arrange the buns cut-side down in the prepared baking dish, cover tightly with plastic wrap, and refrigerate for 10 to 14 hours.
19
The next morning, place the baking dish in a warm-water bath (about 120°F) in a kitchen sink or large roasting pan for 20 minutes.
20
After removing from the water bath, let the buns stand at room temperature until slightly puffy and pressed against one another, about 1.5 hours.
21
About 1 hour before baking, adjust the oven rack to the lowest position, place a pizza stone in the oven if using, and preheat to 350°F.
22
Bake the sticky buns on the prepared stone until golden brown and the center of the dough registers about 180°F (approximately 25 to 30 minutes).
23
Cool the buns on a wire rack for 10 minutes before inverting onto a rimmed baking sheet or platter; scrape any remaining glaze over the buns as they cool.
24
For the Pecan Topping:
25
In a small saucepan, combine the topping ingredients: unsalted butter, brown sugar, corn syrup, and salt. Bring to a simmer over medium heat while whisking until fully combined.
26
Off the heat, stir in the vanilla extract and toasted pecans until they are evenly coated.
27
Spoon a heaping tablespoon of the nut mixture over the center of each sticky bun.
28
Allow the buns to cool for 15 to 20 minutes. Serve warm, pulling apart or carefully cutting them with a serrated knife.
