Quick Pumpkin Mug Cake Recipe for a Cozy 5-Minute Treat

Moist and flavorful – this pumpkin mug cake is a cozy, quick fall treat. Ready in minutes, it requires minimal cleanup and delivers classic pumpkin spice flavor.

This easy pumpkin mug cake is perfect when you want something warm, comforting and fast. It has a tender, moist crumb thanks to the pumpkin puree and a warming pumpkin spice profile from brown sugar and spice. Serve it with a dollop of whipped cream or a scoop of ice cream for an extra treat. Because it’s made in a single mug and microwaved, cleanup is minimal. The recipe is egg-free and can be made vegan by choosing a dairy-free milk.

Prepare the cake right in the mug you’ll cook it in: whisk the wet ingredients with a fork, add the dry ingredients, then microwave to set. The pumpkin keeps the cake soft, while the spice mix gives it that unmistakable autumn taste.

Tips for Making this Pumpkin Mug Cake

• Use 100% pure pumpkin puree, not pumpkin pie filling.
• Light brown sugar adds depth, but granulated sugar works if that’s what you have.
• Choose a larger mug than you think you need; the cake rises as it cooks.
• If you don’t have pumpkin pie spice, substitute 1/4 teaspoon cinnamon plus a pinch each of nutmeg, cloves and ginger.
• Microwave power varies. Cook on medium power and watch closely — cooking too long or using high power often produces a dry or burned cake.
• Remove the mug carefully after microwaving; it will be hot.

Pumpkin Mug Cake

Ingredients

• 1 1/2 tablespoons vegetable oil (or canola)
• 2 tablespoons light brown sugar (granulated works)
• 2 tablespoons pure pumpkin puree (NOT pumpkin pie filling)
• 1/4 teaspoon vanilla extract
• 4 tablespoons all-purpose flour (about 31 g)
• 1/2 teaspoon baking powder
• 1/2 teaspoon pumpkin pie spice (see notes for substitution)
• 1 tablespoon milk (non-dairy milk works to make it vegan)

Instructions

1. In a large mug, whisk together the oil, brown sugar, pumpkin puree and vanilla until smooth.
2. Add the flour, baking powder and pumpkin pie spice. Measure the flour carefully and level it off for best results.
3. Whisk in the milk until the batter is smooth and no lumps remain.
4. Microwave on medium power for 1–2 minutes (about 90 seconds on many microwaves). Watch the cake — it’s done when the top looks set and slightly domed. Avoid overcooking to prevent dryness.
5. Carefully remove the mug (it will be hot). Let the cake cool a few minutes, then top with whipped cream, ice cream, a sprinkle of cinnamon or a drizzle of caramel if desired.

When I have leftover pumpkin puree, I store it in the refrigerator to make this mug cake the next time a craving hits. It’s a quick, satisfying way to enjoy pumpkin flavor without baking a loaf or full cake.

Notes

1. Pure Pumpkin: Use pure pumpkin puree, not sweetened pie filling. Store any leftover canned pumpkin in an airtight container in the fridge.
2. Pumpkin Pie Spice: If you don’t have a spice blend, use 1/2 teaspoon cinnamon and a small pinch each of ground ginger, nutmeg and cloves.
3. Milk: Any milk works — from skim to whole or non-dairy alternatives like almond or oat milk.
4. Nutrition: Nutrition values are estimates for the mug cake alone and do not include optional toppings such as whipped cream or ice cream.
