Easy Chocolate Cookies

I wanted to make some cookies for my colleagues last night and planned to follow the recipes I did earlier. Maybe I want to do it fast, I did not pay much attention to the steps and keep thinking I just dump every ingredients in and mix. Only after I added all ingredients then I realized I need to mix all the wet ingredients first before adding flour. So no choice, I have all ingredients mixed and the mixture was dry at first, so I knead it to form dough. And use hand to form shape, and topped with raisin.
I like how this one bowl formula turned out: cookies are crunchy and smell so good. I like how raisins give extra flavor and texture to the cookies.

2/3 cup vegetable oil
1 tsp vanilla essence
