sugar free lemon ricotta sponge cake

Celebrate the start of 2016 with my sugar free lemon ricotta sponge cake.


I actually made this sugar free low carb beauty yesterday, but I’m enjoying my first mega-slice this morning with a lovely coconut espresso coffee. Mmmhhhh…what a way to start the new year!!! Coffee and home-baked cake. Best combo in the world. Even better when you know it’s uber healthy.sugar free lemon ricotta sponge cake

Is eating more healthy your New Year resolution?

If you’ve stumbled across this page as part of your new year’s resolution to eat healthy and maybe lose weight, you’re in luck. This is where you will find low carb, high fat, grain free, sugar free and often gluten free, ketogenic recipe ideas. There are plenty of excellent books and websites out there that go to great length to explain what keto is and why low carb is best, so you won’t find answers here. I’m a cook, not a writer, so I’d rather spend my time creating,  testing and publishing recipes.

My philosophy on food and why I chose certain ingredients

I bake with a lot of ‘alternative’ ingredients, and you will find links to these supplies throughout my recipes.  I also prefer to use organic, fresh, additive free ingredients and products, even though they cost more. In my mind, it would feel paradoxical to eat lchf in order to improve my health and wellbeing, then not care where my food comes from and what it is. I therefore avoid buying products full of nasties, or chemical concoctions, or products that are grown unethically or are of dubious origin. Many of my supplies cannot be found in local stores. I mainly buy from Amazon.co.uk because a: that’s where I find the vast majority of my baking ingredients under one roof; b: I can buy large quantities; c: there are organic options not available in shops; d: I like the discounts available for recurrent purchases – for which, as an experimental food blogger, I am very grateful.

My ingredients aren’t always the cheapest, but they are always the best quality for the price. For example, I use pure stevia crystals in most of my sweet creations; very expensive for 100g, but when you only use 1/4 to 1 tsp for a whole cake or 600ml of ice cream, you realise that it isn’t as costly a luxury as it appears to be. Why do I use this stevia when there are lots of cheaper stevias available? Because it has almost no after taste and doesn’t alter flavours like cheaper versions that I have tried. And why do I generally use erythritol in combination with stevia? Again, because the 2 complement each other and give the best results.
I have tested and continue to test myriad ingredients all the time, and I only choose what I consider to be the best. So to make my readers’ life easier, I always include links, within my recipes, for the ingredients that cannot be locally sourced. Obviously, no one is obliged to follow my philosophy on food or to buy from my links, so by all means feel free to do whatever suits you.sugar free lemon ricotta sponge cake

My golden rules for every sugar free low carb creation I make.

1) It has to be tasty.
2) It cannot be detected as low carb and sugar free by a standard western diet individual.
3) If it is a rendition of a well known, full carb, sugar loaded recipe, it has to taste and smell like the original or be very close.
4) The recipe must be easy to follow.

An easy, low carb, sugar free lemon ricotta sponge cake for everyone to enjoy.

Whether you’re a low carb beginner or veteran, I am pretty certain that this sugar free lemon ricotta sponge cake recipe will be one that you make time and time again. It is delicious simplicity in itself. If you don’t like pine nuts you can top the sponge with toasted sliced almonds or leave out nuts altogether and sprinkle some icing sugar on top instead.

This cake calls for a little lupin flour to achieve the perfect consistency. But if you don’t have lupin flour, or you have a peanut allergy, you can replace it with the same amount of almond flour.sugar free lemon ricotta sponge cake

Well. All that is left for you to do is get baking and let me know how it turns out for you.

Hi I made this cake and it is delicious but I used Xylitol as my sweetener which was great. One question I did not see where to add the egg yolks in the method so added them with the butter. Did you intend to leave them out? Thanks.


Hi Val, thanks for the heads up. It was an omission, but I’ve now added it.


Your blog is very interesting, i love Italian kitchen – however I do not understand why in most of yours recipients you use some leguminous flours with are forbidden in lchf (and i am allergic for them too 🙁 ..)


Hi there and thank you for your comments. There are no ‘forbidden’ foods in lchf or keto. The reason legumes are best avoided is because they tend to be higher in carbs than other vegetables. However, unlike paleo, which strictly excludes certain foods, keto and vlchf aim to keep carbs intake below a certain level in order to achieve and maintain ketosis. Therefore, when I use ingredients, my main priority is the net carbs count, not the source. Lupin flour has a LOWER carb content than coconut flour, for example, so it’s absolutely fine. If you have an allergy to legumes, which includes lupin, I would advise you to use almond flour instead.


I made the ricota cake Antya. I will tag the pic. It doesn’t look like yours as I did not have the almond flakes or stuff to put on the top. I did not have lupin flour so I tried 20 g of fuba/ polenta fina. Love your recipes. Tks for sharing.


Well done and thanks for your msg! I don’t mind anyone improvising and changing my recipes. Just be aware that polenta flour is very high in carbs, so eat smaller portions!Lupin flour is cheap if you know where to buy it from.The one I’m using at the moment comes from here:https://www.santi-shop.co.uk/en/search.html?keywords=Lupin&x=0&y=0
