Preheat oven to 350 F (180 C).
In a large bowl, mix together flour, baking soda, salt, nutmeg, cinnamon, cloves, and cardamom powder.
In medium bowl mix pumpkin puree with the sugar and whisk it until the sugar dissolves.
Add oil, brown sugar and whisk it again.
Now add the flax meal (2 tbsp flax meal mixed well with 6 tbsp warm water) and mix evenly.
Blend this mixture with the flour mixture and add the chocolate chips too. Mix gently.
Pour the batter into greased 9 X 5-inch loaf pan and bake in the preheated oven for 50 -60 minutes or until a toothpick inserted into the center of the loaf comes out clean.
Let it cool for 20 minutes before slicing to prevent it from breaking apart.
