The recipe is a half (and modified) version of a popular bread from allrecipes.com. I used white whole wheat flour in place of all-purpose, so I like to think it's a little more wholesome. It definitely taste good and is kid-approved. Since this recipe was such a hit, I'd like to find another one with a little less sugar.
The substitute for pumpkin pie spice is 1/2 teaspoon cinnamon (use in addition to the cinnamon already in the recipe), 1/8 teaspoon cloves, 1/4 teaspoon ginger, 1/8 teaspoon nutmeg.
