Hate zesting lemons to get that lovely lemon flavor?  Great – me too!  This delicious Keto Lemon Mug Cake doesn’t use a single lemon and most certainly will not disappoint!  

Keto Lemon Mug Cake

I went to Natural Groceries to look for caramel extract.  I don’t shop there too often, but it was on my way home and I didn’t feel like driving out of my way to Whole Foods.   I had keto mug cakes on the brain!

They did not have caramel extract, but they DID have a few fun other flavors.  I chose lemon and peppermint and I might even go back for the orange!

I hate zesting lemons, but I wanted to try a lemon dessert and make a low carb mug cake.  It is a segway into a more elaborate lemon dessert, but I decided to start small and see if I could get a tasty mug cake recipe with the lemon flavor.

For starters, I had no idea how much to use, so I based it on experience and, well, how strong the smell was!  I went with 1/4 teaspoon in the mug cake and 1/8 teaspoon in the drizzle.  Turned out perfect.

How to Make Lemon Mug Cakes

This is such a simple mug cake recipe, you will just all in love!  I mean, who doesn’t love a dessert in a mug?

To start with, I learned a long time ago that if you coat your mug cups with melted butter that they will easily flip out of the mug once cooked (if that is a goal).

I just melt butter in a separate bowl, pour it in my mug cups and swish it around until a nice thick layer remains.

And besides, butter always boosts flavor, right? You can choose to make one larger mug cake or 2 smaller ones.

I chose 2 smaller ones so I could split it with my 5-year-old!  We could have shared one obviously, but if you have kids, you know they like “their own”.

Mug cakes are so easy to make!  You literally just combine all the ingredients into a bowl, mix them up good, then add the batter to your prepared ramekins.

Microwave for about 90 seconds and boom – you are done!

I like to flip them once they come out so that you get a beautiful, even top!  I know it is just aesthetics, but I like things to look pretty!

Doesn’t that look pretty, even on its own? Light and fluffy for sure!  Not weighted down with flours.  Definitely not “eggy”.

Honestly, my plan was to just make the mug cake without anything else. But when I looked at this beauty, it just looked…. naked.  Like it needed something else.

So I whipped up a lemon glaze and threw some almonds on top and a beautiful dessert was born!

The Keto Lemon Mug Cake Glaze

You can make the glaze thick or thin!  The above picture shows the thick glaze where you just drizzle it on.

For a thicker glaze, you want to use less almond milk.  For a thinner glaze, you want to use more.

Notice below the glaze is much thinner and coats the entire cake.  It is up to you which one you prefer!

Kitchen Essentials

You don’t need much to make this quick and easy keto lemon mug cake.  But you WILL need something to cook it in.  I like the small, white ramekins like ramekins on Amazon!

Sweetener

I chose to use erythritol.  But you can certainly use Lakanto Monkfruit as well.  I use these pretty much interchangeably.

When I use either of these, however, I always use liquid stevia as both together temper the aftertaste of the other.

Flavor

I chose to use Frontier Co-Op Organic and Non-GMO lemon flavor. You can order it on Amazon or, as I said above, I got it at Natural Grocers.

I imagine Whole Foods or New Seasons would have it as well. It is so much easier than zesting or squeezing a lemon!
