Whisk eggs, yolks, sugar and vanilla in an electric mixer until pale and frothy (5-6 minutes). Meanwhile, melt butter and chocolate in a bowl placed over a saucepan of simmering water, stirring occasionally until smooth (4-5 minutes). Add to egg mixture, whisk to combine, then gently fold in flour and pour mixture into a jug. Divide among 10 buttered and floured 250ml metal moulds and press a Mintie into the centre of each. Refrigerate puddings until chilled (2 hours).
Preheat oven to 180C. Bake puddings until they form a dome (20-25 minutes), then invert onto plates, dust with cocoa and serve hot with cream.
