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!

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!
