Orange Chocolate Cheese Cake

I am craving for Cheesecake since my last bake. I forgot which recipes books i came across with this idea, which i had copied down in my note. But, i just wanna to taste how chocolate and orange be together. And, i wanna try the recipe with flour added in making cheesecake.

This time, i am using oatmeal biscuits. I didn't crush until very fine, very small pieces which are bitable. The base turns out very crunchy! Well, i don't really taste the orange flavour in the cheesecake. Maybe juice from only one orange doesn't enough. I suggest to squeeze in 2 oranges and skip away the milk. Flour added cheesecake do taste a little bit like cake.
