    It is “Bake Together” time. Some might be a bit surprised – there was a “Bake Together” two weeks ago and we normally only post once a month… Well, that one was a special one dedicated to the “Day of the German Apple” – Andrea from Zimtkeks & Apfeltarte thought we should honor that day and bake something ;) Now we are “back on track” with our regular schedule – which means once a month at the end of the month – and today is all about low-carb baking! Since everybody is trying to get rid of some extra pounds after Christmas, we thought we should go with the “season” and do something low-carb. And low-carb I did. A delicious Keto Chocolate Cake. It’s hard to go lower with the carbs :P

    Well… of course, there are some people out there that want to eat low-carb food all year round or at least save some sugar or carbs here and there to reduce their calorie intake sometimes. If you want to eat less sugar or carbs, in general, you probably discover sugar replacements at some point. It’s inevitable ;) If you cook a savory meal you might not need those replacements because not many recipes ask for sugar. When it comes to baking most of the recipes ask for flour and sugar. That’s why the sweet stuff tastes so good :P Well – even there are ways to skip it by using ground almonds instead of flour or sugar replacements, for example.

    Though flour replacements are sometimes tricky since almonds will not develop gluten – sugar replacements mimic the original stuff a bit better. Well almost. Eating too much xylitol or erythritol can cause problems with your stomach. So trying to adapt an existing recipe can be tricky if it is asking for a lot of sugar… sometimes you got to try and see what works ;)

    This chocolate cake uses quite a lot of sugar replacement – it is still way below the amount that is said to cause problems if you only eat one slice of cake at a time, but you still should be careful. So better not eat half the cake at once. But that is something you also should not do with a “regular” cake – so both cakes are evenly “dangerous” I’d say :P

    Well… if you want to bake something low-carb, something that’s even good for a keto diet, you might want to try this cake here. It is super chocolaty, rich and sweet. The zucchini gives the cake a great texture and makes it moist – something you always want from a nice chocolate cake ;)

    If you want to know what Andrea did this time, you have to check her blog – I bet she got something nice as well.

    DIRECTIONS / ZUBEREITUNG

    • English
    • Deutsch
    1. Preheat the oven to 350°F (180°F). Line two 8 inches (20m) springform tins and grease lightly. Set aside. Wash the zucchini and shred (not too fine). Set aside.

    2. Add the coconut flour, cocoa powder, xylitol (erythritol), espresso powder, baking powder, baking soda, and salt to a bowl and mix until well combined. Add the eggs, oil, and vanilla extract to a large bowl and whisk to combine. Add the dry ingredients and mix them in. Add the shredded zucchini and fold in. Divide the dough between the two baking tins and smooth out the top. Bake for 25-35 minutes or until a wooden skewer inserted into the center comes out clean. Take out of the oven and let cool down in the tins for some time, then remove carefully and let cool down completely on a wire rack.

    3. For the buttercream add the egg whites and xylitol (erythritol) to a heatproof bowl and place on a pot with simmering water. Mix and heat up until the mixture reaches a temperature of 160°F (71°C). Transfer to the bowl of a stand mixer and whisk on high speed for about 5-6 minutes until light and fluffy – the bowl should have room temperature. Gradually add the butter in small pieces and mix it in. Add the vanilla extract and cocoa powder and mix in – start slow and speed up so you do not end up with a cocoa cloud. Whisk another 2-3 minutes until you get a smooth chocolate buttercream. If the cream seems too stiff or still a bit grainy add some heavy cream and mix in.

    4. To assemble the cake place one cake layer on a serving plate. Add some buttercream on top and spread evenly. Place the second cake layer on top and press down a bit. Cover the complete cake with the remaining buttercream – the surface does not have to be smooth, make some swirls here and there to give it some structure. Place in the fridge for at least 30 minutes before serving.

    1. Den Ofen auf 180°C (350°F) vorheizen. Zwei 20cm (8 inches) Springformen leicht einfetten und mit Backpapier auslegen. Zur Seite stellen. Die Zucchini waschen und (nicht zu rein) raspeln. Zur Seite stellen.

    2. Das Kokosmehl, Kakao, Xylit (Erythrit), Espresso Pulver, Backpulver, Natron und Salz in eine Schüssel geben und gut vermischen. Die Eier zusammen mit dem Öl und Vanille Extrakt in eine große Schüssel geben und gut verrühren. Die trocknen Zutaten dazugeben und alles verrühren. Die geraspelten Zucchini dazugeben und unterheben. Den Teig auf die beiden Backformen aufteilen, glatt streichen und dann für 25-35 Minuten backen – je nachdem wie “feucht” die Zucchini waren, kann die Backzeit stark variieren. Mit einem Holzspieß testen, ob Teig kleben bleibt und die Kuchen erst herausholen, wenn der Spieß sauber herauskommt. Aus dem Ofen holen und in den Formen etwas abkühlen lassen, dann vorsichtig herauslösen und auf einem Kuchengitter komplett abkühlen lassen.

    3. Für die Buttercreme das Eiweiß und Xylit (Erythrit) in eine hitzebeständige Schüssel geben und auf einen kleinen Topf mit köchelndem Wasser setzen. Die Mischung so lange verrühren, bis eine Temperatur von 71°C (160°F) erreicht wird, dann in die Schüssel einer Küchenmaschine umfüllen oder mit einem Handmixer für 5-6 Minuten luftig aufschlagen. Wenn das Baiser steif und glänzend ist und die Schüssel in etwa Zimmertemperatur hat, die Butter in kleinen Stücken nach und nach dazugeben und unterrühren, bis eine samtige Buttercreme entstanden ist. Vanille Extrakt und Kakao dazugeben und unterrühren – erst langsam, damit keine Kakaowolke entsteht, dann auf höchster Stufe für weitere 2-3 Minuten, bis alles gut verrührt ist. Sollte die Creme zu fest wirken oder sich etwas krümelig anfühlen, dann etwas Sahne dazugeben und unterrühren.

    4. Für den Zusammenbau des Kuchens eine erste Kuchenschicht auf eine Servierplatte legen und mit etwas Buttercreme bestreichen, dann die zweite Schicht aufsetzen und dann den ganzen Kuchen mit der Buttercreme einstreichen. Die Ränder müssen nicht glatt sein – versucht hier und da ein paar Wellen in die Creme einzuarbeiten, damit das Ganze etwas Struktur bekommt. Bis zum Servieren noch etwa 30 Minuten in den Kühlschrank stellen.

    Notes

    Enjoy baking! If you don’t want to use sugar replacements, this is also a nice recipe for a “regular” chocolate cake with sugar ;)

      Ive never tried using the sweeteners you suggest in the recipe, I wonder if stevia might work? Im just starting to switch to a low sugar diet and I love baking using half organic sugar and half stevia or maple syrup….but I open to trying new things. I love the base of the cake recipe with coconut and almond flour, those are my new favs for baking! Id love to try this recipe….any excuse for chocolate cake!

        Hi Diana,

        I would not recommend using stevia – you should not use stevia in quantities like the ones from the recipe for sugar/xylitol in a bake. That’s just too much for the stomach to handle ;)

        Cheers
        Marc
