Preheat the oven to 350°. Line a 8" x 4" loaf pan with parchment paper, set aside.
In a large mixing bowl, whisk together the flour, baking soda, pumpkin pie spice, and salt.
Add the pumpkin puree, eggs, Greek yogurt, honey, vanilla, and coconut oil. Stir until just combined—do not overmix or the bread will be tough. Fold in chocolate chips (optional). The mixture will be thick.
Spread into the prepared pan. Top wth 2 tbsp chocolate chips. Bake in for 40-50 minutes, or until the top is brown and cracked, and a toothpick inserted into the center comes out cleanly.
Let cool completely before slicing.
