Josie and I made brownies a while ago, and the recipe she had was very quick and easy, the next day the page of the book she wrote it on got soaked and she couldn't read it any more, so here is a copy transcribed from pictures.
2 cups unbleached all purpose flour
2 cups white sugar (or other)
3/4 cup cocoa
1 teaspoon baking powder
1 teaspoon salt
1 cup water
1 cup vegetable oil
1 teaspoon vanilla extract
1. Preheat oven to 350 f
2. Stir together flour, sugar, cocoa powder, and salt. Pour in water, oil, and vanilla, blend well, spread evenly in a 9 x 13 inch baking pan.
3. Bake for 25 to 30 minutes in preheated oven, until top is no longer shiny, let cool about 10 minutes before cutting into squares.
