Preheat the oven to 350°F. Lightly grease a 9x5 loaf pan and then line it with parchment paper. Lightly grease the parchment as well and set aside.
In a large bowl, combine the spelt flour, cinnamon, baking powder, baking soda, sea salt, chocolate chunks, and chopped pecans. Stir with a spatula to evenly mix.
In an upright blender, combine the bananas, maple syrup, coconut oil, and vanilla. Blend on high until totally smooth and creamy.
Pour the pureed banana mixture into the large bowl with the spelt flour mixture. Use your spatula to get all of the banana mixture you can out of the blender. Gently stir and fold everything together until JUST combined.
Scrape the spelt banana bread batter into the prepared loaf pan, smoothing the top with your spatula. You can garnish the top with extra pecans and chocolate chunks if you like. Bang the filled loaf pan on the counter a couple times to evenly distribute the batter and to fill all spaces of the loaf pan.
Bake the spelt banana bread for 50-55 minutes, or until a cake tester/paring knife inserted in the center of the loaf comes out clean. Allow the banana bread to cool thoroughly before slicing and enjoying.
