How To Make A Keto Pumpkin Mug Cake

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! Learn how to make your own pumpkin puree.
  • Erythritol – for sweetness or xylitol or liquid stevia drops.
  • Pumpkin spices – or combine cinnamon, nutmeg, and ginger. See the 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

Preparing the mug cake batter

This healthy pumpkin mug cake can be made directly into your mug or into a mixing bowl.

Start by combining the wet ingredients, then stir in flour and spices.

Cooking Mug Cakes

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

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.

Check the microwave power

Set the microwave to 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.

Cool down

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

Storage And Making Ahead

Unfortunately, mug cakes don’t store very well because they are baked in the microwave, which is a fast cooking method.

Consequently, the food dries fast, and if you don’t eat your microwaved pumpkin mug cake within 30 minutes, it tastes dry.

However, it is totally possible to make this mug cake batter ahead for a quick and easy keto fall breakfast.

Simply prepare the batter the night before and store it in the fridge in an airtight container.

The next day, microwave as instructed in the recipe below. You may have to microwave the mug cake a little bit longer since it’s cold and straight out from the fridge.

Simply add 10 seconds burst until the cake is set and cooked through.

  • 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 baked in the microwave must be eaten within 1 hour or the texture dries and hardens.


Egg note: This recipe must use egg, it doesn’t work with a flaxegg or egg replacer.
Flour note: This recipe must use a combination of both flour, almond flour, and coconut flour.
Nut-free option: swap almond flour with the same amount of sunflower seed flour or pumpkin flour and use pumpkin seeds as a topping instead of pecans.

    4 Thoughts On Keto Pumpkin Mug Cake
  1. 5 stars
    I ran out of coconut flour, but really wanted to make this recipe. After some research, I discovered that cassava flour was a possible alternative. I tried it, and it turned out fantastic! I can’t wait to try it when I have coconut flour!
