When you combine the warm, earthy spices of cinnamon, nutmeg, and ginger with creamy, comforting pumpkin puree, and then kiss it all with some chocolate, you've got a special, very yummi snack or dessert!
Heat oven to 350 degrees F.(177 degrees C). Place rack in the middle of the oven.
Line 12 muffin cups with paper liners and spray each cup lightly with non-stick vegetable spray.
In a large bowl, sift together the flour, baking soda, ground spices and salt.
In a medium bowl, whisk the oil and sugar until well combined. Add the eggs, one at a time, whisking well after each addition. Mix in the pumpkin puree and vanilla extract. Scrape down the sides of the bowl.
Alternately add the flour mixture and sour cream, in three additions, beginning and ending with the flour mixture. Lastly, fold in the candied ginger and chocolate chips.
Fill the muffin cups evenly with the batter using two spoons or an ice cream scoop. Place in the oven and bake for about 18 - 20 minutes, or until firm to the touch and a toothpick inserted in the center of one of the muffins comes out clean. Place on a wire rack to cool.
