Preheat your oven to 350°F (175°C) and grease a standard loaf pan.

In a large mixing bowl, combine melted butter with both sugars until creamy and thick. Add eggs and beat until fluffy for about 2-3 minutes.

Incorporate pumpkin puree and vanilla extract, stirring until the mixture is well combined.

In a separate bowl, whisk together flour, baking soda, cinnamon, pumpkin pie spice, and salt until there are no lumps.

Gradually add the dry mixture to the wet mixture, stirring gently until just combined. Avoid overmixing.

Pour the batter into the prepared loaf pan and smooth the top with a spatula.

Bake for 60-65 minutes, checking for doneness with a toothpick in the center.

Allow the pumpkin bread to cool in the pan for about 10 minutes before transferring to a wire rack to cool completely.
