2 cups unbleached flour
2 cups white sugar
3/4 cup unsweetened cocoa powder
1 teaspoon baking powder
1 teaspoon salt
1 cup water
1 cup vegetable oil
1 teaspoon vanilla extract
Preheat the oven to 350 degrees.
In a large bowl, stir together the flour, sugar, cocoa powder, and salt. Pour in water, vegetable oil and vanilla; mix until well blended. Spread evenly in a 9x13 baking ban.
Bake for 25-30 min. in a pre-heated oven, until the top is no longer shiny. Let cool for at least 10 min. before cutting into squares.
