**Preheat Oven:** Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan with non-stick cooking spray or line it with parchment paper.
**Mix Ingredients:** In a large mixing bowl, combine the spice cake mix, pumpkin puree, and eggs. Stir until well combined and smooth.
**Transfer to Pan:** Pour the batter into the prepared loaf pan, spreading it out evenly.
**Bake:** Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
**Cool:** Allow the pumpkin bread to cool in the pan for 10 minutes, then transfer it to a cooling rack to cool completely before slicing.
