Preheat oven to 350°F. In a large bowl, mix together melted butter, brown sugar, pumpkin puree, and egg using a whisk.
In a separate bowl, mix together whole wheat flour, instant oats, ground flaxseed, wheat germ, wheat bran, baking soda, and pumpkin pie spice.
Add dry ingredients to wet ingredients and mix until well combined. Fold in chocolate chips. Put mixture in freezer for 10 minutes.
Using a teaspoon, drop spoonfuls of batter onto a baking sheet lined with parchment paper. Bake for 10-12 minutes. Remove from oven and let cook on baking sheet for 5 minutes. Remove from pan and let cook on wire rack.
