Oreo Cheese Cake

Oreo Cheese Cake is the first cake that I made on my own many years ago. I instantly fell in love with this cake when i first ate it at Starbucks. Although it don't taste as good as my No.1 favourite Dessert Tiramisu, I like this as well. I would rank it No.2.

I bought my first baking tin specially for making Oreo Cheese Cake. It's a 7" x 3" round baking tin with a loose base. Searched for few recipes and i start baking the my first cake.
It turn out not too bad but i would still rate it FAIL.
The flaws are:

> the cheese cake filling was too rich
> the oreo cookie that was on the base and wall of the cake was too hard...not crumbly soft at all >.<" FAIL!!!
