Cream cheese cake cookies

I made these this weekend and omg are they yummy.  I got the recipe online but I did a cut and paste so I don't remember where online I got it.

1pkg cream cheese
1/2 cup of butter
1 egg
1tsp of vanilla extract
1 box of yellow cake mix
1 bag of milk chocolate chips.

Heat oven to 375.  Cream together the cream cheese and butter, add the egg a vanilla.  Add the cake mix a little at a time until well mixed together then add the chocolate chips.  Bake on cookie sheet for 12 minutes and enjoy!
