Melt dark chocolate and butter, set aside for few minutes to cool down then add sieved cocoa powder in

Beat egg yolk and vanilla with half the sugar until you get a foamy / creamy texture then fold into chocolate mixture

Beat egg whites with the rest of the sugar until it forms peaks (meringue like) then fold it into the chocolate mixture

Coat your little ramequins / foils with butter, dust them with caster sugar then pour your mixture into it (just above half of the ramequin / foil)

Bake for 7/8 minutes at 180 degrees (this will vary depending on the size, depth and width of your ramequins / foils)

Serve and enjoy immediately with a dollop of whip cream 😉
