Choclate chip cookies

Today I made chocolate chip cookies with a group of friends. First we got the ingredients and then we mixed the ingredients after that we put the cookies in the oven and we washed the cookies and ate the cookies. The raising agent we used was Baking Powder.

Recipe
100g of butter
1/2c of sugar and brown sugar.
1 tsp vanilla essence
1 egg
pinch of salt

Melt Butter, and add both sugars and cream these together. Beat in the eggs and vanilla then mix in the dry ingredients. Roll into medium sized balls, making sure the mixture is not too wet! Put on a well greased baking tray. They shouldn't spread too much so flatten slightly.
Bake for 8-10 minutes.
