Preheat oven to 350℉.
Spray a 9x5 loaf pan with cooking spray.
In a stand mixer fitted with a paddle attachment beat together the sweet potato puree, eggs, oil and vanilla extract. Once combined add in both sugars. Mix for 2 minutes.
In a small bowl combine the flour, baking powder, baking soda, cinnamon, ginger, sea salt, nutmeg, cloves and allspice. With the mixer on low, slowly add the flour mixture. Mix until fully combined and you no longer see any flour bits. Using a silicone spatula stir in the chocolate chips.
Pour the batter into the prepared loaf pan. Sprinkle the top with 1/4 cup chocolate chips.
Bake for 1 hr 20 min. - 1 hr 30 min. or until golden brown and set in the middle. Remove from oven and let cool slightly before removing from pan to cool fully.
