This low-carb chocolate cake roll is filled with homemade sugar-free Nutella and mascarpone, and covered in dark chocolate ganache. This delicious keto treat takes a little more work than most recipes but it's totally worth the effort. If you can't eat dairy, I listed paleo-friendly options.
Before I get to my new recipe, there's something troubling I'd like to talk about. It affects us directly and creates unnecessary overhead. You can help us fight it.
We Need Your Help to Fight Fake Reviews
Over the last few months, our app has been the target of fake reviews on the App Store. Initially, we assumed that this was just a coincidence - we're not naive to expect that everyone will like our app. But we soon realised that this is not a coincidence based on the consistency of the false claims.
Although developers like us can now report fake reviews and respond to them directly, the only way to counter balance this is to convince genuine users to leave honest reviews.
To prove our point, I include a few of the fake reviews below.
Exhibit A: the elephant in the room

Top prize goes to "Awesome tracker" who forgot to change the name before leaving a negative review. It wouldn't be the first time our competition used shady tactics to mislead people in an attempt to damage the good name of our app.

Exhibit B: the deceiver

The user claims there is "no tracker" and there are "no recipes included" for our fully featured KetoDiet App. Ironically enough, tracking is the main feature of the KetoDiet app which also includes hundreds of recipes.

Exhibit C: the serial app store abuser

Apple detects unusual behaviour and in the case below, they refused to offer the reviewer a refund due to "evidence of fraud, refund abuse, or other manipulative behaviour".
The review below was changed several times, each time with a different story, until the "reviewer" decided to go with the single line of "I didn't care for this app".

Our message to those using our KetoDiet app is simple: If you want us to work on improving the app and creating more free recipes rather than spending our time filling up forms to report fake reviews, then please leave an honest review on the App Store or Google Play. It only takes a minute and will help us focus on what really matters - making our app the best we can. Thank you for your support!

Step-by-step
Preheat the oven to 175 °C/ 350 °F. Crack the eggs into a bowl. Using an electric mixer or a hand whisk, beat until frothy. Add the salt and slowly sift in the Erythritol while beating.
Gently fold in the almond flour and add the vanilla.

Pour the dough into a tray (38 x 28 cm/ 15 x 11 inches) lined with heavy-duty parchment paper. Bake for 8-10 minutes, until set and lightly golden. Do not overcook the sponge or it will break when you roll it.
When done, remove the tray from the oven. Flip the sponge onto another piece of parchment paper and cover with a dump (but not too wet) kitchen towel. Leave to cool down for 2-3 minutes. Then, gently peel the parchment off the sponge.

While still warm, tightly roll the sponge with the parchment paper. Let it cool down for a few minutes while you prepare the filling.
Note: it may help if you score a small shallow indention with a sharp knife, about 1 cm (1/2 inch) along the edge on the side you will roll.
Prepare the filling by mixing the homemade Nutella and mascarpone cheese in a bowl.

Once the sponge has cooled down, gently unroll it. Spread the Nutella-mascarpone filling inside. Do not go too close on the edges to prevent the filling form oozing out as you roll it.
Roll the cake by pulling the paper towards you and use your other hand to shape the sponge into a roll. Place in the fridge while you prepare the ganache.

To make the ganache, break the chocolate into small pieces and place in a small bowl. Heat the butter with the cream in a saucepan over medium-high heat. Once foam starts to develop on top, slowly pour it over the chocolate while stirring, allowing the chocolate and the cream mixture to combine. Set aside to cool.
What if my ganache breaks? If the fat separates from the rest of the ingredients—don’t panic. Place in a blender and pulse until smooth!


Spread the ganache evenly over the top and sides of the cooled roll and place back in the fridge for at least 20 minutes before serving.
Slice and enjoy! Keep refrigerated for up to 5 days.

If you want to reduce the carb count, halve the coating. I ended up with a thick chocolate layer and even half of the amount would be sufficient to cover the roll.

I made this cake yesterday and it is delicious. I used very little Truvia and 100% dark chocolate, so it was not sweet enough for non-keto family, but I found it delicious and surprisingly easy to make.
Thank you Sanna, I'm glad you all enjoyed! 😊
Unfortunate that you are having this issue with reviewer(s). I actually searched for.your app on google play and it did not come up. Is is the same name - keto diet app? If not would you please email app name to me? Tia
Hi Barbara, thank you very much for your kind words! You can find all about our app on the home page: ketodietapp.com (as long as the icon looks like the one on the home page, it is our app). I hope this helps!
I absolutely love the KetoDiet app! I've used it now for about six months, and they continue to upgrade it. It has thousands of recipes, which are easily integrated into daily planning. It is often the last thing I use before I go to bed, with planning the next day. And one of the first things I open in the morning, to see what wonderful breakfast I will have on that day.
Thank you so much Sheryl! I would be grateful if you could leave a review on the App Store. Thank you for your kind words and support! ❤️
I made this cake yesterday and it is absolutely delicious. Thank you Martina for all the great recipes!!!!
I'm glad you liked it Amanda! Thank you for your kind words!
I saw the reviews and your responses which were very polite... Sadly what you describe is very common and it's not always down to shady competition. Many apps face the same issues. Some folks don't want to pay for apps because they don't understand the costs of app development (by the way it's my job to develop apps for Android). Some are even willing to lie to show who is in charge of your success. Frankly, as a customer I don't want to see complaints about pricing when I know how much I'm paying before clicking the “buy” button. I want to get a good idea of what the app has to offer. I wonder if those reviewers would walk into BJ's only to order a meal and then complain about the price. That would be cheap and embarrassing. If it's not what you're willing to pay, don't buy it. It's that simple.
Thank you Greg, I appreciate your support! Developing and maintaining an app is more difficult than most people realise. Even I cannot fully appreciate it because I'm not involved in all the technical aspects and complexities of coding - that's my partner's job. Some people simply have unrealistic expectations and are not willing to pay a fair price. When it comes to pricing of apps, it's a race to the bottom.
I love your blog and appreciate all you do. I won your app in a giveaway a few months ago and wanted to leave a review but it looks like I can't :-( Am I doinf something wrong?
Hi Sam, yes, that's correct. Apple doesn't allow those who use promo codes to leave reviews. Thank you for your kind words!
I can't wait to try this one! Is there a way to make it nut free?
Hi Christine, I think you could try coconut flour instead. I'd only use about 1/2 cup of coconut flour instead of the 1 1/2 cup of almond flour. I hope this helps 😊
I love your nutella and made it twice since last week... My cooking skills are limited but I'll give this one a go too :-D By the way I love your app, use it every day and left a review a few months back. Keep up the good work!
Thank you so much Kelly, I really appreciate that!
