Keto Pumpkin Spice Mug Cake


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. Its 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 defiantly try is our Keto Pumpkin Cheesecake Shake!

Best Sweetener For Mug Cakes

For this tasty treat, as we do with all of our dessert recipes, we used Lakanto’s Monkfruit as our sweetener. For this Mug Cake we used their version on confectioners sugar, Lakanto Powdered Monkfruit Sweetener. Monkfruit is a completely natural, zero glycemic, and delicious sweetener that we can’t recommend enough! Be sure to use Monkfruit for all of your dessert recipes.

If you’ve never tried Monkfruit before and want to try it for the first time, or if you just need to restock, shop Lakanto’s website HERE and use our code “BUTTERTOGETHER” to save 20% off of your ENTIRE purchase! That includes Monkfruit or anything else you find on their site!
