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.”

How do I convert to almond flour? I don’t have any coconut, and I don’t care for it in baking. The liquid would need adjustment I think?
Yes, a lot of adjustments to swap with almond. 1/4 cup is about equal to 1 cup almond so you’d need a lot more.
I spelled carver wrong in my email. This is a correction
I don’t have any lemon stevia, will another sweetener work?
Yes, here’s my conversion chart to use another sweetener. https://www.sugarfreemom.com/recipes/natural-sugar-free-low-carb-sweeteners-guide-conversion-chart/
I made this for my Mother’s Day treat and it was delicious! I topped it with keto whipped cream. Next time I will add a little vanilla and poppyseed. Thank you for sharing this recipe! I am sharing it with 2 gluten allergic people I know. I will give them your blog website so they can enjoy all your delicious recipes.
This was very good other then I have a hard time with coconut flour. I wish I liked it more. I have learned to cook only 55 seconds in the microwave. Do you have another flour I could use instead? Oh use real lemons. Didn’t have any so I tried lemon juice from the store. Yeah not as good.
Oh my goodness this is delicious. Thank you so much. Xx
Oh my word, this was sooo dry and coconutty…
If it was dry, it was overcooked.
Delicious! I’ve made it 5-6 times. I didn’t have heavy cream or stevia today, so I used plain yogurt and 1 TBLS ethryitol. Tasted just as good as when I made it with the original ingredients. Perfect with a cup of Earl Grey tea!
Excellent recipe, nice texture, perfect sweetness. I’m a fussy baker, but it passed my test 🙂 I didn’t have heavy cream, so I replaced with greek yogurt. I also added a dash of lemon Zest and blueberries.
This was really good! Made as directed. Even hubby loved it. We did a dollop of keto whipped topping on top of it and we were in Heaven! I will definitely make it again! Thanks!
