Preheat oven to 375°F.
Using a large chef knife, slice the top and stem off the pie pumpkin. Slice the pumpkin down the middle from top to bottom. Remove the seeds with a spoon.
Place both halves of pumpkin face down on a baking sheet and roast for 30-40 minutes or until the pumpkin is fully softened. Let cool.
In a large bowl, add softened butter, brown sugar and mix until thoroughly combined.
Scoop the roasted pumpkin out of the rind/skin. Add 1 cup of cooled pumpkin puree to the butter and sugar mixture and incorporate/mix together.
Add in the eggs, one at a time, then the vanilla extract.
Gradually add the flour, baking soda, baking powder, and salt.
Finely shred a cup of carrots and add to the batter along with the pecans. Mix the batter until everything is incorporated.
Pour batter into a greased loaf pan and top with additional pecans and pumpkin seeds.
Bake the loaf for 30-45 minutes or until an inserted toothpick comes out clean when inserted.
Let cool 30 minutes. This recipe is extra delicious with butter or whipped cream!
