3/4 cup packed light brown sugar (5 1/4 ounces)
3 tablespoons corn syrup, light or dark
2 tablespoons heavy cream
1 pinch table salt
Cinnamon-Sugar Filling
3/4 cup packed light brown sugar (5 1/4 ounces)
2 teaspoons ground cinnamon

3/4 cup pecans (3 ounces), toasted in a skillet over medium heat until fragrant and browned, about 5 minutes, then cooled and coarsely chopped
Preparation
Arrange buns cut-side down in prepared baking dish; cover tightly with plastic wrap and set in warm, draft-free spot until puffy and pressed against one another, about 1 1/2 hours. Meanwhile, adjust oven rack to lowest position, place pizza stone (if using) on rack, and heat oven to 350 degrees.
Place baking pan on pizza stone; bake until golden brown and center of dough registers about 180 degrees on instant-read thermometer, 25 to 30 minutes. Cool on wire rack 10 minutes; invert onto rimmed baking sheet, large rectangular platter, or cutting board. With rubber spatula, scrape any glaze remaining in baking pan onto buns; let cool while making pecan topping.
For the topping: Combine butter, brown sugar, corn syrup, and salt in small saucepan and bring to simmer over medium heat, whisking occasionally to thoroughly combine. Off heat, stir in vanilla and pecans until pecans are evenly coated. Using soup spoon, spoon heaping tablespoon nuts and topping over center of each sticky bun. Continue to cool until sticky buns are warm, 15 to 20 minutes. Pull apart or use serrated knife to cut apart sticky buns; serve.
