In a medium sized bowl, mash the bananas and set aside.
In a large mixing bowl, stir the sugars together with the butter. Then add the eggs and mix thoroughly.
Add bananas, baking soda, cardamom, salt and vanilla and stir to combine. Then add in the flour and mix the batter. Fold in the pecans and pour the batter into the prepared loaf pan. Smooth the top of the loaf, and add a few whole pecans to the top.
Bake at 350 for 55-60 minutes, or until a toothpick inserted in the center comes out clean.
Allow to cool before slicing.
