Low Carb Lemon Slice

lemon slice

This low carb lemon slice is a light and fluffy cake that is covered in a rich lemony cream cheese butter topping.  It’s so good that you could serve it to your friends and they would never know that it’s a much healthier version of the store brought cake.

I was hankering for a lemon cake today and thought that I would try a low carb lemon slice recipe with ideas of a creamy lemon topping.  So I grabbed my trusty tub of coconut flour, a couple of lemons and got to work.   There is something so satisfying (and probably a bit smug) about a recipe working the first time.  I had am image of what I wanted the low carb lemon slice to be and this was almost spot on.  The creamy topping can be optional, but I would just drop to my knees and beg of you “why?!”.  


It was lunch time and the Chief Taster came home for lunch in time to sample these delights.  He placed two on his plate telling me that he was doubling up as I had told him that they were good.  He scoffed both in record time and didn’t come home at the end of the day asking what was for dinner.  So they do keep you going all day.  A happy husband too!  You can’t put a price on that.  Well, you can, but the cost of making these is probably a lot less that I would estimate.  Cheaper than taking him shopping for “man gifts” too!  


As we are still getting settled in our new place and I need a table in the spare room that would be great for photos, I took the photos of these outside in our garden.  You will start to see a difference in the background of my photos compared to the recipes that I made in Barbados.  They were full of a green leafy background.  Here, I have a lot of cactus and rocks.  Perhaps when we get our garden table, I can angle the plates a bit better.  Or I set up a photo station with the usual food props, so you would never know what country I am in!

    Hi! Tried your recipe tonight with halved ingredients because I didn’t want to make too much cake. It turned out too greasy/wet and undercooked 🙁 could not rescue it even though I tried baking it for longer time.

    I wonder if it’s because I’ve used a few subs: I used avo oil instead of butter; honey instead of sweetener; and flax eggs instead of eggs. I love lemon cakes and would wanna give it another shot! But I don’t want another uncooked cake 🙁

      Hi, yes I would say it’s the substitutions and the honey would have made a more wetter cake.

    I can’t tolerate erythiol, what would be the equivalent measurement for honey or coconut sugar?

      It’s a sugar replacement. Similar to Xylitol.
