doubt on 原味乳酪?

Hi, maomaoMOM, could you help me figure this out?     I used Kraft PHILADELPHIA cream cheese (regular), not sure if that is 原味乳酪.  When I done the cream, sugar and egg mixing, the mixture looked more liquid than what you did. The other steps I can follow easily and have no problems.  The cake came out like an apple pie, I mean the inside texture look like that way. When I cut it with knife, the cake lost its shape and the cream cheese flew everywhere .  Thank you.
