Preheat the oven to 350º F (180° C). Line a small, 4-cup loaf pan, with parchment paper. You can also use a silicone loaf mold.
In a medium-sized mixing bowl, mix eggs with baking soda thoroughly until soft peaks start to form.
Add pumpkin puree and pumpkin pie spice, and mix for at least 2 minutes until well combined. Then throw in 2 tablespoons of crushed pecans and incorporate them.
Pour the batter into the loaf pan or mold, and sprinkle with remaining pecans.
Bake for 30-45 minutes until the interior is cooked through. A toothpick inserted in the middle must come out kind of clean but moist. Let rest before unmolding.
