Source of recipe: This is my veganized version of Tollhouse cookies.
Preheat oven to 375 degrees Fahrenheit.
Mix together flour, soda and salt and set aside. In large bowl cream together oil, sugar, brown sugar and vanilla. Mix in mashed banana and baking powder. Add flour mixture, and stir well. Add chips. Drop by rounded tablespoons onto cookie sheet*.
Bake 9-11 minutes.
*Use banana and baking powder or other equivalent to 1 Egg (banana and baking powder is what I use... it works really well, actually).
*The original recipe said to use an ungreased cookie sheet, but I like my cooking spray too much. So I always spray everything before baking in it... I don't think it really makes a difference.
