Sugar Free Lemon Ricotta Sponge Cake to Celebrate the start of 2016.



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. What a lovely way to start the new year!!! Coffee and home-baked keto cake. Best combo in the world.

Is eating more healthy your New Year resolution?

If you’ve stumbled across my site 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 an array of low carb, high fat, grain free, sugar free and mostly gluten free, ketogenic recipe ideas. My blog is still in its infancy, so please accept my apologies for the lacklustre style and poor photography. I’ll get there eventually…

My philosophy on food and why I choose 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, but not care about the origins of my food. I therefore avoid buying products full of nasties, or products that are grown unethically or are lab made. Many of my supplies cannot be found in local stores. I mainly stock up from Amazon because:  firstly, it’s where I find the vast majority of my baking ingredients under one roof; secondly: I can buy in bulk easily; thirdly: there are organic options not available in shops; and lastly: 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, pure stevia powder is in most of my sweet creations. I don’t buy the cheapest, but the one that has the most intense sweetness with the least aftertaste. According to my taste buds.  Erythritol often accompanies stevia in my sweet recipes. In my opinion, the 2 complement each other well 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 Gold 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. If you have a peanut allergy, you might want to avoid lupin, just in case. You can substitute it with almond flour.sugar free lemon ricotta sponge cake

All that is left for you to do is to get baking.

  1. Hi Antya, I made your sponge cake, only replaced lemons for oranges (+ made a little marmelade from the remaining oranges, pectin and erythritol). It was really delicious, thank you!

  2. Hi Antya!
    I made your sponge cake yesterday, only replaced lemons for oranges, it was realy delicious.
    And because the cake was sweetened only with a little protein with stevia, I made jam from the remaining oranges (with citrus pectin and erythritol).
    Amazing breakfast 🙂 Thank you!

  3. 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.

  4. 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.

  5. Top really top.

  6. 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.
