Step 1

Preheat oven to 180C (350F). Grease a 20cm loose-bottomed cake tin and line with baking paper.

Step 2

Place drained beans, eggs, sugar, vanilla, baking powder and a good pinch fine sea salt into a small food processor and blend until smooth, stopping to scrape down the sides if needed. Add chocolate and blend until combined. Transfer mixture to prepared cake tin and bake 25-30 minutes, or until a skewer comes out clean when inserted into the centre. Remove from oven and set aside to cool. Serve dusted with cocoa powder or ice with chocolate ganache for an extra chocolate kick.
