Prepare Your Oven and Pans: Set your oven to 325°F (165°C) and place the oven rack in the center position for even heat circulation. Grease two 8x4-inch loaf pans generously with butter, then dust them lightly with flour to prevent sticking. Alternatively, use a non-stick baking spray that contains flour for quick prep.
Combine the Dry Ingredients: In a medium-sized bowl, whisk together the flour, salt, baking soda, baking powder, and the trio of warm spices: cloves, cinnamon, and nutmeg. Ensure everything is thoroughly mixed for a balanced spice distribution throughout the bread.
Cream Butter and Sugar Until Fluffy: Using an electric mixer, beat the softened butter and sugar on medium speed until the mixture is pale and light in texture. This creaming step helps incorporate air for a tender crumb.
Incorporate Eggs and Pumpkin: Add the eggs one at a time, beating well after each addition to ensure full incorporation. Then mix in the pumpkin puree. The batter may look a bit grainy or curdled here—this is completely normal and will not affect the final bread texture.
Blend Dry Ingredients Into Wet: Reduce the mixer speed to low and gradually add the flour and spice mixture to the wet ingredients. Mix just until combined; avoid overmixing to keep your bread moist and tender.
Bake the Loaves: Divide the batter evenly between the prepared loaf pans. Bake in the preheated oven for 65 to 75 minutes. The bread is done when a toothpick or cake tester inserted in the center comes out clean or with just a few moist crumbs attached.
Cool and Serve: Allow the loaves to rest in their pans for about 10 minutes after baking, then transfer them to a wire rack to cool completely. This helps the crust set and prevents sogginess.
