Preheat the oven to 350 degrees. Prepare the loaf pan by spraying it well with non-stick coating, set aside.
Lightly chop the nuts.
Add the ingredients into a large mixing bowl and mix by hand until just combined. Spoon into the prepared loaf pan.
Bake at 350 for 45 minutes. Insert a toothpick in the middle of the loaf to check if it is done. If you can remove it cleanly, the loaf is ready to come out of the oven. Rest on the cooling rack for 10 minutes then run a knife around the edges of the pan. Invert and allow the loaf to cool completely on the rack before slicing.
Notes
You can substitute the spice cake mix with a yellow cake with a teaspoon of pumpkin spice added to the cake mix.For longer shelf life, wrap it in plastic and then foil. Refrigerated it will last 5-7 days. Freeze - up to 3 months.
