BB Special Thanksgiving Sweet Potato Pecan Caramel Bourbon Pound Cake

A moist, tall sweet potato cake, with caramel pecan streusel, and a warmed marshmallow glaze atop the sticky brown sugar bourbon topping, which echoes the sweet potato and marshmallow casserole we serve with the turkey. Phew! This is an extravagant, holiday cake no one will forget which is what makes it an instant new tradition. Hint: the darker the sweet potatoes, the prettier the interior crumb and hue of this cake. If you don't want to bother with the streusel, leave it out. This cake rocks no matter what. It's......yammy. Seriously, it's one for the ages. Which is why it is now enshrined in The New Best of BetterBaking.com, Marcy Goldman, Whitecap Books, 2009 (available at Amazon, Chapters, Indigo, Barnes and Noble)
