Ingredients
Method
Preheat oven to 180°C/160°C fan. Grease a deep 22cm round springform pan. Line base and side with baking paper.
Place cacao, butter and chocolate in a large heat-proof bowl over a medium saucepan of simmering water (do not allow base of bowl to touch water). Stir until melted and smooth. Remove bowl from heat and cool for 15 minutes.
Meanwhile, combine coffee and boiling water in a heat-proof jug. Beat eggs and sugar in a small bowl with an electric mixer for 2 minutes or until thick and creamy. Stir in coffee. Add
egg mixture to chocolate mixture, stirring until just combined. Fold in hazelnut meal. Pour mixture into pan.
Bake cake for 45 minutes or until a skewer inserted into the centre comes out clean. Leave cake in pan for 30 minutes.
VANILLA BEAN CREAM
Scrape seeds from vanilla bean, reserving pods for another use (see tips). Place cream, vanilla seeds and sugar in a medium bowl, beating with an electric mixer until soft peaks form.
Dust cake with extra cacao and serve with vanilla bean cream.
We used rapadura, but any unrefined sugar can be used. The vanilla pods (after scraping the seeds) can be placed in a jar of sugar to make vanilla-flavoured sugar.
From the Test Kitchen
