Preheat your oven to 350℉. Butter two loaf pans or one loaf pan and one muffin pan. Since this batter makes a lot, you can have one classic loaf and use whatever shape pan for the rest of it.
Combine the dry ingredients into one bowl and whisk together. Flour, baking powder, baking soda, salt, and spice mixture. Set this aside.
In a larger bowl, add very soft butter and sugar. Stir on medium for 2 minutes. If whisking, then stir until the butter appears lighter in color.
Add in eggs and vanilla. Once completely combined, stir another minute to get a bit more air into the batter.
Now, you can stir in the pumpkin.
When the pumpkin is fully incorporated, add half of the dry mixture.
Mix, scrape down the sides, and add in the rest of the dry mixture.
Once this is all together, you are ready to put into your pans.
Smooth the top and place your pans in the oven. Bake for 65-70 minutes. The loaf will clearly have risen and will become sightly brown.
If you buttered your pan, the bread should pop out easily and you can cool on a wire rack.
You can enjoy the bread plain or add my delicious cream cheese frosting.
