Preheat oven to 350 degrees F. Line 8.5 x 4.5 inch loaf pan with parchment paper, butter, then flour, respectively
Cream butter and sugars until one cohesive mixture
Add eggs, one at a time, until fully incorporated
Whip the mixture until light and airy
Add pumpkin puree, discard, and vanilla one at a time
Meanwhile, combine dry ingredients in a seperate bowl
Slowly add the dry ingredients while mixing slowly
Pour batter into an 8.5 x 4 inch loaf pan (see 1st step for how to prepare it)
You can either bake immediately or ferment the dough in the fridge for a day or two. Resting the dough is optional but will add more flavor and fermentation benefits!
Sprinkle the pumpkin seeds in one layer on top of the dough
Bake for 1 hour and 15 minutes or until a toothpick comes out clean
Let bread completely cool in the pan on a wire rack
