This 2-ingredient pumpkin bread is a moist and delicious cake. It can't get any easier than this! Great when frosted with your favorite cream cheese frosting. Plan ahead, tastes best after chilling.
Preheat the oven to 350 degrees F (175 degrees C). Generously grease a 9x13-inch baking pan with cooking spray.
Mix spice cake mix and canned pumpkin together in a large bowl until well combined; spread evenly into the prepared pan.
Bake in the preheated oven until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. Cool and serve, or store in the refrigerator to serve the next day.
