Low Carb Cake – Chocolate Frosted Marble Cake

Low Carb Cake – Chocolate Frosted Marble Cake

Low carb and cake aren’t two words that you would usually see together. However, I was in the mood for something sweet a few days ago, and I thought to myself I should make a cake, so I did!

Now this was my first go at making a full on cake. I know I’ve made waffles and even a couple small cookies here and there, but never an actually all out decorated cake.  I also am most certainly not a baker, but I think it turned out pretty good.

I am also not particularly artistically inclined, so I thought I could just drizzle my chocolate “ganache” all over the top to make my cake slightly more aesthetically pleasing. After I did it, I got the only opinion that mattered (Rae’s), and she said it looked good, so I put this one down as a success.

Now you probably could have split this cake in half and then put the creme in the middle, which was actually my original plan, but I am definitely not all that confident in my baker cutting skills, so I just put it all over the cake instead.

Although this was a bit of an experiment in baking, the end result was still tasty. Using a spring form pan and some parchment paper, this popped right out from the pan after it was done baking. I used a silicone head spatula to spread my whipped cream “frosting” all over the cake. After chilling for a few hours, it was ready to eat!

Now I know I called this a chocolate frosted marble cake, and I promise it is, but I completely forgot to take any pictures of slices, and we ate it all before I could :(.

I did, however, make a little video of me making it, so here you go!

I’m still working on my videographer skills, and believe me, getting natural lighting to be the same all the time is not easy! Still, I hope this video helps out with seeing the actual process of making this cake.

Also, I know this is posted as a marble cake, but it wasn’t actually meant to be one. It just somehow kind of turned out that way. If you make this at home, and you mix it really well, it may just turn out to be a chocolate cake. Either way, it’ll be delicious.

  1. This looks really good and you make it look so easy and quick to make. I might let my kiddos make this with me, since it would use our shaker and they can’t get enough of stuff like that. However, they would probably try to eat all of the sweet ingredients before they would make the pan! I really like that you included the nutritional facts in your post. Did you base that off of rationing all of the ingredients and amounts you utilized?

    1. I think your kids would have a blast making up the whipped cream frosting. It certainly gave me a bit of an arm workout while I was making it. To answer your question about the nutritional facts, I did input all of the ingredients and amount I used into a calorie count calculator. Then I set it to make 8 servings since that’s how I cut my cake. I hope that helps!

  2. We have been trying eat healthier in our family. This looks like a great thing to make for desert. I like that it is low in carbs. We will defiantly try this one out. Thank you.

    1. You are very welcome! I think it’s great to know that you can still eat deliciously and healthy all at the same time! I hope you try it out and let me know how it turns out! Thanks for stopping by!

  3. Low carb and chocolate sound like a dream and you don’t often hear about this combination.

    Being a real chocolate lover and cake lover this is music to my ears as I’m a fitness fanatic and have to sacrifice things like this.

    I’m going to the shop now for ingredients.

    What other surprises you got like this?

    1. I’ll certainly have some new ones coming up soon. I’ve actually got one planned with a little patriotic twist coming up for 4th of July. Check back soon!

  4. Well you made me hungry for cake, it looked so good. As I was watching the video, I was thinking God I hope the ingredients are listed as well, so I was glad to see the list and instructions were included on the page. Awesome work 🙂 Where did you learn this from?

    1. I actually kind of adapted the recipe from my waffles recipe and increased the amounts of certain items and added in chocolate. For the ganache I just researched google and thought instead of using cream I would try it with coconut oil. I hope you try it out and let me know how it turns out!

  5. Wow! As a diabetic (one who suffers from immmense chocolate cravings) this cake looks amazing. Now I can have my cake and eat it too! Whoo hoo! You got me as a subscriber now, keep the good stuff coming!

    1. Absolutely! I definitely think this would be great for a diabetic as the carb content is really low for a slice. Although i’m not quite sure what the threshold is for a diabetic, I think it would work out well. I’ll definitely have some more good stuff coming up soon!

  6. Hey cool post!
    I really enjoyed your video, and I hear what you have to say about natural light. If you have a small board (or something you could prop up). wrap it in aluminum foil! and leave it off screen.
    The goal with this is to reflect light onto the scene. So even if say an hour later your cake is done, and there are clouds or the sun has moved. You can just angle your aluminum board to help recreate the lighting from earlier. Professionals use this technique sometime (although its definitely more expensive than aluminum) Hopes this helps mate, the cake looks delicious!

    1. Thanks for the great information! I actually had to use mirrors to reflect sunlight into my kitchen because there are no windows in there. I’ll definitely give the aluminum foil a shot though for my next go. Thanks!

    1. I’m glad you think so! It may not be perfect like one you would get at a bakery, but it definitely tasted good!

  7. Another excellent recipe, Pete. I love that these recipes have your personal touches. You really go out of your way to make a cake healthier! I should say ‘less harmful,’ but you get the idea. How can I make sure it’s a marble a marble cake? I’d prefer that to a regular chocolate cake?

    1. I definitely try to make my recipes healthier than their full carb counterparts and just as delicious. If you want it to be a true “marble” cake, I would suggest folding in the chocolate during the cake process rather than completely mixing the two together. This will allow the cake to have more of that marble look to the cake. Hope this helps!

  8. Hey Pete

    Another great recipe, and like always so well explained, you even make it like everyone can do it! I think I’ll go for the chocolate one .


    1. Thanks Ruben! I definitely try to lay out and show instructions in such a way that anyone can do it. My recipes are made for the regular person just trying to eat a little bit healthier without sacrificing taste. I hope you do try the chocolate and let me know how it turns out!

  9. I’ve never ever baked before. But out of curiosity and a sense of adventure, I want to see if I can make a chocolate marble cake turn out alright on my first attempt. I will be following your guide every step of the way. Thanks for this!

    1. I had never baked a full on cake before this either! I hope you do try it out and let me know how it turns out!

  10. Wow, that looks so yummy and easy to make. My daughters are always looking for good recipes so I will be passing a link to your site along. Looking forward to some more great recipes. 🙂

    1. I’m so glad you like the recipe! I would be honored if you passed the recipes on. I love sharing recipes and how I can make them low carb. Thanks for stopping by!

  11. Hi Pete

    This cake look so yummy! I’ll always come back here to check your new recipe, and this cake is awesome easy to make. This really nice for dessert. Thanks for sharing!


    1. You are certainly very welcome Eric. I thought this was a good one for my first dessert on the site. I’m glad you liked it!

  12. Before I even read all the way through or watched the video (well done) I said to myself. Low Carb Cake? I bet stevia was used instead of sugar. I am a big fan of stevia.

    That cake, though it didn’t turn out the way you planned, still looks tasty. Sometimes plans that don’t work out to be what was hoped for can sometimes turn into a better end result. I know I have come up with some great recipes from things that didn’t quite work out as planned.

    Thanks for the video. Now I am hungry for cake. And like you, I am not a baker. 🙂

    1. Stevia is my number one sweetener to use in all my recipes that need some sweetening agent. My recipe didn’t turn out like how I had planned since it was supposed to be a two tiered cake with the cream in the middle and the ganache all over the top, but it still turned out great!

  13. interesting cake there. Will ask my girlfriend to cook for me hehe XD
    It should be really yummy from how it looks. I see that there is stevia. What is it?

    1. Stevia is a natural sweetener that comes from a plant but is zero calorie and zero carb. It isn’t created synthetically like a lot of sweeteners like Splenda. I also think the taste doesn’t have that artificial taste to it like some sweeteners have.

  14. Wow! This is low carb?? I’m sure my wife would be happy to hear that. We’ve been trying to eat healthier for awhile but there’s always certain food that tempts us. This will surely be a great dessert to kill those cravings. Looks delicious!

    1. This is absolutely low carb! I think desserts were one of the hardest food groups to cut down on when I first start dieting, but luckily there are ways to still have things like cake while on a low carb lifestyle. Of course, I believe that moderation is still key to any good program. Thanks for stopping by!

  15. That cake makes me salivate as it looks so tasty! However whilst there is no unhealthy sugar to sweeten the recipe I am a little concerned about the fat content mentioned in nutrition facts per serving ( 110% of saturated fat, 39% cholesterol and 42% total fat ) which wouldn’t be too good for one’s waistline! Still as an occasional indulgence no harm I guess.

    1. I would definitely think that cake would be best as an occasional indulgence, but the idea of fats making people fat has been pretty much thrown out in light of much recent research. The majority of the fat content in this recipe comes from the use of coconut oil, which has been found to have a ton of benefits. In the end, however, it comes down to total calories in versus out that makes people fat. The main thing would be to watch out for cholesterol, which can increase with way too much fat. As always, I think everything should be in moderation. I believe that the 100+ pounds of weight that I dropped can be thought of as a type of proof that the low carb way does help. Hope this helps!

  16. Wow I’m amazed at how low carb this cake actually is. I wasn’t expecting that at all. Did it still taste sweet? Did the texture come out light and fluffy or heavier? I’m not really an expert at baking so this is pretty new to me. Thanks for a great article!

    1. I am absolutely not an expert at baking, but the end result turned out a little bit between really dense and a regular cake texture. Coconut flour is pretty notorious at being dense, but the addition of the whey protein helps to lighten it up some.

    1. Thanks for signing up! I’m still in the process of setting up my emailer for my list, but i’ll definitely have something up soon. Thanks for stopping by!

  17. Wow that is great that it is low Carbs so now I can actually enjoy it. Thank you for breaking everything down to the very end making it easy to get things prepared. It really looks yummy and I feel like it is my duty to make some. LOL. Thank you for sharing and I’ll let you know how it turns out. Cheers

    1. You are very welcome. I try and make it clear and simple as to how I cook. I hope you do try it out, and check back soon! I’ll be making more treats!

  18. Crumbs! Cake, chocolate, low carbs and a helpful ‘How to do it’ video, I’m sold 🙂

    The ingredient list and directions were straightforward and I can assure you that the end result disappeared with hungry teenagers extremely quickly. Many thanks!

  19. Wow! Looks really good. You always make the most delicious looking cakes Pete. I will also need to try this out. I wish I had your baking skills!

    1. Well I think anyone can make these. This is especially true as I am not a baker. I made the video to show how simple it really is. I hope you do try it out!

  20. Wow, it looks delicious. Is it gluten free, my wife has a gluten allergy so it’s not easy to find cakes she can eat, and when she does find one they tend to be fairly average. If it’s not gluten free do you have any recipes.

    1. You know what, I believe this recipe is actually gluten free. There is no flour other than coconut flour which is gluten free. Everything else is mainly cheese and stevia. I would of course check, but I am pretty certain this is a gluten free recipe. I’ll have to start labeling them as so. I actually believe the majority of my recipes are all gluten free. Of course double check, but I never use actual flour or anything like it in my recipes. Hope that helps!

  21. This recipe is an absolute Godsend. I was actually searching for something that I could attempt to make as a birthday cake for my wife. I guess my search is over now 🙂
