Decadent Double Chocolate and Olive Oil Cake

Decadent. There is no better word to describe it. Moist, rich, delicious, my best chocolate cake so far.

I have been a fan of Nigella Lawson for quite some time. I like her shows, her British accent, her easy to make recipes.

I was surfing her website, under the gluten free section, and I came across this Chocolate and Olive Oil Cake. Shut the front door!!! Olive Oil? I am Portuguese, olive oil is something I use every single day. Chocolate? Oh yes, one of my favorite foods. Gluten free? Awesome!

The cake was not keto, but if it was I would always give it my touch and tweak it a bit. I did not do much on this one. Used macadamia nut flour (I like the texture and that it has less carbs than almonds), replaced the sugar with a keto approved natural sweetener, used one more egg (as I did not have large ones), a bit less olive oil to balance the liquids, and at the end added chocolate chips.

It is to die for! It will make a fantastic birthday cake, and for the festive season you can slightly tweak it to add a couple of spices and nuts of your choice.

I paired it with a few fresh strawberries (chocolate and strawberries never go wrong), but then decided to make a keto salted caramel and see if it would go well. It did. It is a match made in heaven. As the cake is not much sweet, the salted caramel makes a lovely contrast with it.

Nutrition per portion

  • 150g macadamia or almond flour
  • 4 medium eggs
  • 130ml olive oil
  • 50g sifted 100% cocoa powder
  • 125ml boiling water
  • 1 tsp vanilla extract
  • 1/2 tsp baking soda
  • 4 heaped tbsp swerve, or other sweetener to taste
  • pinch of salt
  • 1/2 cup dark chocolate chips
  • Preheat your oven to 150°C (Fan).
  • Grease a square pan (like the ones used to make brownies and line it with baking paper (strong wax or parchment).
  • In a bowl add the cocoa powder and the boiling water and whisk until you have a smooth mix (more liquid than a cake batter. Let it cool down while you go ahead with the next step
  • In another bowl, add the macadamia nut flour (or almond flour), the bicarbonate of soda and a pinch of salt. Whisk it to remove lumps and mix the ingredients
  • In another bowl, add the eggs, vanilla extract, olive oil and sweetener and beat on high-speed (I used a hand-held cake mixer) until it is creamy and aerated.
  • On low-speed, add the cocoa mixture, and beat well. Add the dry ingredients and beat to mix well.
  • Fold in the chocolate chips
  • Pour the batter (it is runny) into the prepared pan. Bake for 40-45 minutes (insert a cake tester/toothpick, if it comes almost clean but with moist chocolate crumbs clinging to it the cake is ready).
  • Put it into a wire rack to cool for 10 minutes. When cooled down, take it from the pan, peel the baking paper off it and leave to cool
I ate it with strawberries and later made keto salted caramel, it is a match made in heaven. My colleagues at work (they are my guinea pigs lol), could not stop raving about it.

    Good morning Dalila, from sunny Playa del Carmen, Mexico! For this Double Chocolate and Olive Oil Cake recipe, you say Preheat your oven to 150°C (Fan). Can you tell me what you mean by Fan? And if I don’t have a Fan in my oven, should I change anything?

      If you google fan assisted oven will understand. I cannot tell you what to do besides adjusting the temperature as needed, because each oven is different fron the other, sorry

    Okay – I checked and it is Convection oven where we live. I can find what I need to do differently. Interesting how terms are different around the world! Thanks Dalila!!
