Weigh out the ingredients
You'll need flour, vanilla, pumpkin puree, sugar, baking powder, baking soda, salt, pumpkin spice, pumpkin seeds, eggs, brown sugar, and brown butter.
Brown the butter
In a small saucepan, melt 297g of unsalted butter over medium heat, stirring with a rubber spatula to encourage even cooking. Once it turns a dark golden color and the fat solids have darkened and settled at the bottom of the pan, immediately pour into a large bowl.
In a large bowl, whisk together the flour, baking powder, baking soda, pumpkin pie spice, and ½ teaspoon salt. Set aside.
Combine the dry ingredients
To the brown butter, whisk in the sugars, then the eggs and vanilla until fully combined.
Mix in the sugars
Then, whisk in the pure pumpkin puree.

Add the dry ingredients to the wet ingredients and gently mix until fully combined.
Mix wet & dry
Pour the batter into the prepared loaf pan and smooth out the top.
Add batter to pan
Use a knife to draw a straight line down the center of the batter. Pipe the brown butter along the line. Sprinkle pumpkin seeds on top, if desired. Bake the pumpkin bread for 1 hour to 1 hour 10 minutes or until a deeply golden and a toothpick inserted comes out clean.
Top & bake
Allow the pumpkin bread to cool completely in the pan. Use a serrated knife to cut individual slices and enjoy!
