This Pumpkin Spice Mug Cake is the ultimate single-serve dessert for fall. It’s soft, fluffy, and filled with warm pumpkin flavor and cozy spices—ready in just 5 minutes from start to finish. No baking skills, oven, or cleanup required.

I remember creating this recipe on a chilly autumn evening when I wanted a homemade treat without turning on the oven. One mug, a few pantry ingredients, and 90 seconds in the microwave later—I had the perfect fluffy cake topped with whipped cream and a sprinkle of cinnamon.

It’s made with real pumpkin puree, a touch of brown sugar, and those essential pumpkin pie spices. This dessert is naturally vegetarian and easy to customize with chocolate chips, chopped pecans, or even a dollop of cream cheese frosting.

Perfect for weeknights, solo treats, or late-night cravings. This pumpkin spice mug cake brings all the cozy fall vibes—with none of the wait.
