what to do
步骤
preheat oven to 450°f; butter and flour four 4-ounce ramekins.
预热烤箱到450华氏度（230度），准备一个4盎司左右的模具。
in top half of double boiler set over simmering water, heat butter and chocolate until chocolate is almost melted.
将巧克力和黄油隔水融化（小编提醒：千万不要直接放微波里加热）
beat eggs, yolks and sugar until light colored and thick.
搅拌鸡蛋、蛋黄和糖知道颜色变浅。
mix chocolate and butter, and slowly pour into egg mixture, stirring constantly. stir in flour until just combined.
混合巧克力和黄油，慢慢倒入蛋液中，持续地搅拌至完全融合。
pour batter into molds and bake for 6 to 7 minutes. cake centers will be quite soft. invert molds on plates. let sit 15 seconds. unmold. serve immediately with whipped cream.
把搅拌物倒入模具，放入烤箱烤6-7分钟。这样蛋糕的外层成型、而里面就是液体状的。把模具翻转到盘中，静置15秒后脱模。吃的时候可以配上鲜奶油。
