Keto Pumpkin Spice Mug Cake
Jump to...
Introduction
Keto mug cakes are one of the easiest desserts/snacks you can make. No preheating an oven, no greasing a pan, and no hassle necessary.
To make this delicious keto mug cake, all you’ll need is a microwave safe mug (duh!), an egg, some cream cheese, butter, and some spices! No special trip to the grocery store needed.
Another great thing about mug cakes is that they are the perfect serving size. If you’re like me, sometimes making a whole cake just doesn’t make sense. It’s just Dylan and me at home, so unless we eat cake after every meal, sometimes it gets dry and needs to be thrown out before we can finish it all.
With a mug cake, though, you have the perfect amount every time. No need to waste precious cake, or gorge yourself so that you don’t have to throw it out!
Another simple and delicious pumpkin treat you should definitely try is our Keto Pumpkin Cheesecake Shake!
How To Make Keto Pumpkin Spice Mug Cake:
- Melt butter in the microwave for approximately 20 seconds.
- Whisk an egg and add it to the melted butter.
- In a mixing bowl, mix all the other ingredients.
- Add the melted butter and egg to the other ingredients, mix, and pour into a microwave safe mug. Microwave for 90 seconds.
Best Sweetener For Mug Cakes
For this tasty treat, as we do with all of our dessert recipes, we used Lakanto’s monk fruit as our sweetener. For this Mug Cake we used their version of confectioners sugar, Lakanto Powdered Monk Fruit Sweetener. The powdered blend is the one to use here: a mug cake is in the microwave for barely a minute, which is not long enough to dissolve granulated crystals, and a gritty mug cake is the usual way this one goes wrong.
