Sugar Free Lemon Mug Cake

This easy lemon mug cake is perfect for when you just want a single serving and not have any left overs in the house. It's gluten free, grain free, tree nut free and absolutely lemony!

If you live in New England or any place that has had frigid temperatures and a whole lot of snow over the last couple of months, you can be certain we are all ready for the spring season!

I am a lemon lover truth be told. Love them in my water, seltzer and in recipes as much as possible like this Sugar-Free Frozen Lemonade, this Strawberry Lemon Sorbet, and these delicious No Bake Lemon Cheesecake bars! 

Spring time for me means lots of fresh produce and ingredients. The aromatic smell of lemons remind me of spring no matter  what season it is.  They're  just so fresh;  I always feel rejuvenated when I can get my daily whiff.

I have even been known to ingest the juice of an entire lemon as a shot to help cure a sore throat. Might sound harsh, but I can tell you it works better than anything I've ever tried.

I've made this recipe 4 times before posting it. I am always looking for the perfect and moistest first bite. I tried with different combinations of coconut four, one time with some flax seed, then 2 eggs, then more lemon, but finally what I'm sharing is the best combination.

Not too much lemon, just enough. Perfectly soft in texture. And I can honestly say even if you are not a coconut fan you'll love this. My littlest man hates all things coconut and loved this cake! The coconut is not noticeable at all, the lemon is the star, I promise!

Coconut Is Not a Tree Nut

I'd like to clear up this constant question get asked almost daily about whether coconut is a nut. While the US Food & drug Administration (FDA) claims that coconut is a tree nut becomes it comes from a tree, it is in fact a FRUIT.

People who have tree nut allergies may be allergic to coconut as well, but being allergic to coconut is not the same as having a tree nut allergy.

My own son was diagnosed with a Peanut and Tree Nut allergy at the age of 2. He has safely eaten coconut all these years without issue and he is now 14. Coconut is a fruit, called a drupe. It's like a peach with a pit. 

The American College of Allergy, Asthma and Immunology says it well: "Coconut is not a botanical nut: it is classified as a fruit, even though the FDA recognizes coconut as a tree nut. While allergic reactions to coconut have been documented, most people who are allergic to tree nuts can safely eat coconut. If you are allergic to tree nuts, talk to your allergist before adding coconut to your diet."
