Keto Cubic Cake? Wait, what is a cubic?

“A volume that is made by a cube that is 1 meter on each side. Its symbol is m³. It is equal to 1000 (one thousand) liters. Example: A box that is 2 meters wide, 2 meters long and 0.25 meters deep has a volume of 2×2×0.25 = 1 m^3″.

Is this 1 cubic meter of a cake?

No, 😀 but it can be if you’d like to increase the volume! The beauty of assembling a cake made of small cubes is in the possibility to shape it in any amorph shape and still have it looking attractive. I remembered a similar cake from the long-gone carby years when baking a cake was my weekly routine. Luckily, after almost two years of Keto baking, I developed recipes and solutions which can compete with unhealthy, but great-looking carby cakes.

Repetition is… the mother of learning

It’s not about Keto baking tricks, it’s about when and how to have Keto cake! In fact, Keto cake can be utilised in a positive way! First, it will cut the cravings and at one point you’ll not want a cake at all. This really happened to me! After making so many Keto cakes, I came to the point where I just want to serve them to others. I can’t even eat it because I had enough great Keto food in my main meal.

But, A Keto cake is only good if it has mega-healthy and nutrient-dense ingredients. Furthermore, it’s really Keto if it has less than 4g net carbs per slice. This is the only way you can judge a recipe if it’s meant to fit your Keto Medi lifestyle.

How do you start with this cubic project?

After you baked this perfect chocolate sponge cake, all you need to do is cut it into small cubes. This is why I call it Keto cubic cake! Try making real cubes just to stay on the geometric point of this story! Of course, you don’t have to be 100% precise, but try to make it approximate.

You don’t have to use the same pan as I did, the volume will be the same, and your cake might end up taller or thinner. Once the cake is baked, you will measure the height you got and then cut the cubes into the approximately same length and width. For example, if your cake turned out to be 2 cm (1 inch) tall, that’s gonna be your cutting square size. So, you’ll end up with 4 square cm cubes! Then, while your cubes are cooling, (and this will speed up the cooling) you will prepare one of your favourite Keto cake fillings and use it as your “concrete”

Making The Keto cubic cake filling

Cake filling in the world of Ketonia is prepared with fatty ingredients. Regardless of your choice, let your filling be the leader in this case. Make a lot of it and make sure it’s thick enough to allow you the buildup! Now, if you decide to follow my exact recipe, make sure you have the top quality ingredients because you want your Keto cubic cake to be nutritious and healthy! Furthermore, you want it to impress both Ketonians and Non-Ketonians. In fact, when I get a compliment from a carboholic person, then I know that my Keto cake is really great. Not only healthy but also seductive for those who still rely on sugar for pleasure 😉

This cake was tasted by a long term Ketonian (Apollonas) and Non-Ketonian and the Non-Ketonian liked it even more! Ketonian thought it was too sweet, which is natural. I will, therefore, reduce the amount of sweetener in the recipe. You can adjust the amount, but definitely don’t overdo…
When it comes to sweetewner on Keto-Less is more has never sounded better!
The secret of a perfect homemade chocolate icing
There’s no need to use industrial sugar-free chocolate filled with all sorts of additives, emulsifiers and emulators. All you need is organic cacao powder, butter and cream – the rest is some spices! Healthier and easier than melting industrial chocolate.
Use your best tools – your hands!
Once you’ve dipped your cubes into your wonderful keto filling, you will be assembling the cake with your hands. Be creative here… Create any shape you want. It doesn’t have to be perfect. In the end, when you cut it, the cubes will do the trick 😉

So, shall we be making this Keto cubic cake? You will see that it’s much easier than it looks!

1/2 tsp 1/2 tsp baking soda
2 tbsp 2 tbsp psyllium powder
6 tbsp 6 tbsp hazelnut or almond flour
2 tbsp 2 tbsp grated citrus zest
1 tbsp 1 tbsp natural rum flavouring (or just use real rum)
1/3 tsp 1/3 tsp nutmeg
Mousse
3 large 3 large yollks
200 g 7 oz butter
200 ml 6 3/4 fl oz heavy cream (additive free)
2 tbsp 2 tbsp coconut flour
12 drops 12 drops edible banana peel oil (optional)
Icing
100 g 3 1/2 oz butter
200 ml 6 3/4 fl oz heavy cream (additive free)
2 tbsp 2 tbsp organic cacao powder
1 tbsp 1 tbsp vanilla extract
1 tbsp 3 tsp Ceylon cinnamon
1 tsp 1 100% monk fruit powder
1 pinch 1 pinch sea salt
Directions
First, prepare the filling so it can totally cool down while the cake is being baked. Using an electric mixer, beat the egg yolks with the sweetener. Bring the heavy whipping cream to a boil and mix it with melted butter. While it’s still hot, slowly pour it to the yolks and keep mixing at a high speed. Now add coconut flour and banana oil (this is optional). Mix well and leave it in the refrigerator to cool down.
For the cake, beat the eggs with the sweetener, salt, baking soda and citric acid. Add melted butter and sour cream. keep mixing at medium speed.
Mix almond or hazelnut flour with psyllium powder and lemon/orange zest. Add this mixture to the cake batter spoon by spoon. keep beating. In the end, add natural rum aroma, nutmeg and Ceylon cinnamon.
Preheat the oven to 200ºC (400ºF). Line a 30×20 cm (12×8 inch) pan with parchment paper. Pour the cake batter in and even it with a spatula. bake for 30 minutes. When the cake is baked, take it out of the oven and let it cool down a bit. Cut the small cubes out of your cake. (I cut them 2×2 cm)
Let the cake cubes cool down totally. Take the filling out of the refrigerator and mix it with the cake cubes. Use your hands!
Transfer this mixture on a wide plate and form a cake. You can make the cake in any shape you prefer. Then place it in the refrigerator for at least 30 minutes.
In a deep pan, melt the butter and then add the cream. Have it at a low temperature. Add cacao powder, sweetener and spices. stir until it’s all nicely unified. Let it cool down before pouring it on the cake.
You can play with the icing and let it run down the sides of your cake, or you can create circles on top by pouring the icing slowly with a spoon. Be creative!
It would be ideal to cut and serve this cake the next day!

Notes
We use Julian bakery 100% monk fruit powder. This sweetener is just dried and ground monk fruit. It’s 100% natural and the best flavour of all Keto friendly sweeteners.
Banana peel edible oil is a rare but magic baking flavouring. It has all the aromatic oils of banana but has no carbs. You can, of course, use another natural flavouring.
