I’m always impressed with how quick and easy it’s to make a keto dessert in a mug. It takes less than 5 minutes from start to finish, and you get to enjoy a grain-free tasty pumpkin mug cake. Before keto, I wasn’t a fan of mug cakes as I didn’t like the spongy texture, but keto mug cakes are way better, super fluffy, and buttery!

Today’s star is this single-serve healthy sugar-free pumpkin mug cake that screams FALL, and you can top it with homemade whipped cream or chocolate chips. 

By the way, if you enjoy this recipe, you can find more festive keto recipes, perfect for holidays in my new The Keto Holidays 40+ recipes e-cookbook.

Thanksgiving is so close, and all you can think is of that pumpkin bread you can’t wait to devour? Well, while on my blog, I have a recipe for a delicious keto pumpkin bread you have to try, this single-serving keto pumpkin mug cake tastes the same.

It’s so delicious and so fast! A classic pumpkin bread takes more than one hour to bake. This sugar-free pumpkin mug cake takes less than 3 minutes.

Ingredients for Keto Pumpkin Mug Cake

  • Pumpkin Puree – Canned or homemade, make sure to use pumpkin puree, not pumpkin pie filling that loaded with sugar.
  • Butter – Melted butter is the best here as it adds such a tasty buttery flavor. You can use coconut oil if you’re looking for a dairy-free pumpkin mug cake alternative. The texture is similar if using either of these fats, but there will be a slight difference in taste as the coconut oil adds a coconut flavor. 
  • Eggs – Only one egg is required for this single serving keto dessert in a mug, and it’s best to use a large egg at room temperature. It’s important to use a large egg because when baking with coconut flour. If there’s not enough liquid, the mug cake can become super dry! 
  • Sweetener – My favorite sweetener to use that has zero after taste is this Monk Fruit Blend that can be used to replace sugar in any recipe. For a paleo pumpkin mug cake, I recommend the same quantity of coconut sugar of paleo-approved sweetener. 
  • Baking Powder
  • Pumpkin Spice Seasoning – Is what completes the flavor of this pumpkin mug cake and add that delicious fall flavor. I love to use about 1/2 tsp or a combo of cinnamon, nutmeg, and ground cloves.
