This incredibly easy recipe for a Classic 3-Ingredient Pumpkin Spice Cake uses a box cake mix, pumpkin puree, and water to create a moist and flavorful dessert with minimal effort. It's perfect for a quick fall treat or holiday gathering.
This cake is delicious on its own, but you can also serve it with a dusting of powdered sugar, a dollop of whipped cream, or a simple cream cheese frosting for an extra treat. Store leftovers in an airtight container at room temperature for up to 3 days.
