Nigella’s chocolate olive oil cake is a moist, gluten-free chocolate cake made with almond flour, cocoa powder, and olive oil. The olive oil gives the cake a unique richness and tenderness, while also making it dairy-free. It’s delicious on its own or paired with a dollop of whipped cream or fresh berries for an elegant finish.
Preheat your oven to 170°C (150°C fan). Grease a 9-inch round cake tin with olive oil and line the bottom with baking paper.
In a small bowl, whisk the cocoa powder with the boiling water until smooth. Stir in the vanilla extract and set aside to cool slightly.
In a separate bowl, mix together the ground almonds, baking soda, and a pinch of salt. This ensures the baking soda is evenly distributed throughout the cake.
In a large mixing bowl, whisk the caster sugar and eggs together until the mixture is light, pale, and slightly thickened, about 3-5 minutes. You can use an electric mixer for this step to achieve a smooth consistency.
Slowly pour in the olive oil and the cocoa mixture, whisking continuously until well combined. This creates a rich and glossy batter.
Gently fold the almond mixture into the chocolate batter until everything is fully incorporated. Be careful not to overmix to keep the cake light.
Pour the batter into the prepared cake tin and smooth the top. Bake in the preheated oven for 40-45 minutes, or until a skewer inserted into the center comes out clean or with a few moist crumbs.
Allow the cake to cool in the tin for 10 minutes, then transfer it to a wire rack to cool completely. Serve as is, dusted with powdered sugar, or with a dollop of whipped cream and fresh berries.
