    Slice potatoes in half lengthwise and scoop the flesh into a large bowl. Mash with a potato masher or fork, then press through a fine-mesh sieve into a clean large bowl to remove any lumps. Add the brown sugar, Traeger Smoked Simple Syrup, eggs, cream, butter, vanilla, thyme, and Traeger Chicken Rub and stir well to combine. Transfer to the prepared baking dish and smooth the top.
