When you’re craving something sweet, it doesn’t get any easier than this Keto Lemon Mug Cake! Ready in minutes using only a microwave!
Easy Low-Carb Lemon Mug Cake
One of the most challenging things about a low-carb diet for me is that I crave sweets!
To set myself up for success, I have a few go-to keto dessert recipes that satisfy my sweet tooth, without all the sugar.
When I’m craving chocolate, these Keto No Bake Cookies are my favorite. However, sometimes I want a different flavor and this Keto Lemon Mug Cake fits the bill just perfectly!
It’s one of the easiest recipes possible – simply stir and cook! You don’t have to be an expert cook (or even a good cook for that matter) – which is a good thing because my husband is the one with all the talent in that department.
If I can handle this recipe, anyone can!
Now there’s no excuse not to stick with your clean eating…wink, wink!

Prep Tips:
Make sure to use a microwave-safe ramekin or mug for this cake. If sharing, you might choose to cook in a ramekin because it is easier to remove the cake and serve on a plate. If enjoying alone, a mug works great!
Softening the butter and cream cheese first makes it easier to mix in the dry ingredients evenly.
We used Erythritol as our sweetener, but you can use a keto-friendly sweetener of your choosing.
