A yellow cake mix can replace spice cake mix if needed. If using yellow cake mix, consider adding a little extra cinnamon or pumpkin pie spice to enhance the fall flavor.
Walnuts can replace pecans, or the nuts can be omitted completely for a nut-free variation.
For a slightly richer pumpkin flavor, add a teaspoon of vanilla extract to the pumpkin mixture.
Serve individual portions with whipped cream, vanilla ice cream, caramel sauce, or a light dusting of cinnamon.
