Notes
You can use any oil in this recipe, but I prefer ones that don't have a strong taste, like canola or vegetable. You can substitute the sour cream for Greek yogurt.Use pumpkin puree, not pumpkin pie mix.You can substitute the cinnamon, nutmeg, ginger, and clove mixture for pumpkin pie spice. Just use 1 1/2 teaspoons of pumpkin pie spice. If you choose not to use mini chocolate chips, you can add something else like chopped walnuts. But this is also optional.
