I have been playing around with keto desserts in preparation for my holiday menus. This pumpkin mug cake is wonderfully fluffy and light and tastes of pumpkin spice.

Sugar Free Maple Syrup Ingredient

This was my first time using a keto-friendly sugar free sweetener. I used a maple flavored sugar free syrup to complement the other fall flavors in this mug cake. I purchased Lakanto Maple Flavored Sugar-Free Syrup online.* (This is an affiliate link.

The ingredient list of this cake may look daunting, but most of them are Fall spices. I definitely recommend using all four as they each provide a different flavor to the cake.

How to choose a Mug

This cake will rise quite high during cooking before sinking back down. You will need a mug that holds at least 16 oz of liquid. You can replate the cake in a smaller mug after it is cooked for presentation.


You can garnish this cake with fresh whipped cream, more syrup, chocolate sauce, etc. I drizzled mine with sugar free caramel sauce.
