Mug cake ingredients

This keto low-carb pumpkin mug cake is made of less than 10 wholesome ingredients. All you need to make this single-serve dessert are:

  • Pumpkin puree – use canned pumpkin puree NOT pumpkin pie filling!
  • Erythritol – for sweetness or xylitol or liquid stevia drops.
  • Pumpkin spices – or combine cinnamon, nutmeg and ginger, see recipe card for the exact amount.
  • Egg – this recipe doesn’t work with flax eggs or egg replacers, you must use an egg.
  • Baking powder – for a fluffy cake.
  • Coconut oil – or melted butter for a denser buttery pumpkin pie mug cake.
  • Almond flour –  this is a gluten-free pumpkin mug cake using a combination of two gluten-free keto flours, don’t swap one for another or the cake texture would not be good.
  • Coconut flour –  don’t replace coconut flour with almond flour, these flours are very different and can’t be substituted for each other.  The combination of flours creates the perfect moist and fluffy texture. More coconut flour will dry out the cake.
  • Vanilla extract

Cooking time and tips

Keto mug cake recipes are not difficult to bake cake in the microwave, but it requires a few tips before you start.

  1. Use a tall microwave-safe mug

At least 6.5 cm height (2.5 inch) and 8.5  cm width (3.4 inch). This is about 1 1/2 cup (400ml) coffee mug. That’s the perfect size to make the best keto pumpkin mug cake, that fits the mug, stays moist, and bakes evenly.

2. Check the microwave power

Set the microwave on 800W, this is the standard temperature for a 90-second keto mug cake. If your microwave only has a power of 600W, it will take longer to bake. Start with 90 seconds then add 10-second bursts until the center is fully set, not runny, or moist.

3. Cool down

Always wait 1 or 2 minutes before decorating your mug cake with cream. This prevents the whipped cream from melting.

This pumpkin keto mug cake is even better with some toppings. The best fall keto toppings for your mug cake are:

  • Unsweetened whipped cream – or dairy-free coconut yogurt if dairy-free for a paleo pumpkin mug cake.
  • Ground cinnamon – add a pinch of cinnamon on top of your hot cake!
  • Chocolate chips – add 1 tablespoon of sugar-free chocolate chips on top of the cake or in the batter.

  • In a medium-size bowl whisk the egg with the pumpkin puree, melted coconut oil, and vanilla extract.
  • Whisk in almond flour, coconut flour, erythritol, baking powder, cinnamon, nutmeg, and ginger.
  • Transfer the batter to a tall microwave-safe coffee mug, its minimum size must be 500ml, 2 cups to prevent the mug cake from overflowing
  • Microwave at 900W for 90 seconds or until the cake rises out of the mug and the middle is set. It is a moist mug cake so it may have a small area in the center that stays a bit wet but not under-cooked!
  • If the cake is still too wet in the center, return to the microwave by 15-second bursts until baked to your liking.
  • Wait for 1 minute before adding unsweetened whipped cream on top of the mug, chopped pecan and a drizzle of sugar-free maple syrup.

Oven baking method

  • Preheat oven to 350°F (180°C).
  • Grease a 2-cups / 500-ml oven-proof ramekin with butter or coconut oil.
  • Pour the cake batter in the ramekin and bake for 15-20 minutes or until set in the center.


  • A mug cake bake in the microwave must be eaten within 1 hour or the texture dries and hardens.
