Not for the faint of heart...there's really not much 'healthy' about these, but they make up for that in sheer chocolatey goodness. This is my grandmother's recipe - admittedly, she probably got this off of the back of a box way back when but so what. It's been in our family now for over fifty years, and is always requested during holidays. Says something about the flavor!
Anyways, on to the recipe.
In a large mixing bowl, combine the following:
3 cups white sugar (no substitutions allowed...already mentioned they weren't healthy.)
1 1/2 cups flour*
1 cup dutch cocoa powder
2 teaspoons baking powder
*if not using all-purpose flour, add a teaspoon of salt and extra teaspoon of baking powder. Also, one cup flour and 1/2 cup ground flaxseed works well if you want to change it up a bit.
After stirring, add:
1 1/2 cups vegetable oil
6 eggs
1 or 2 teaspoons vanilla extract
(depends on the strength/flavor intensity of your extract - standard store bought stuff, 2 tsp. - fancy vanilla, 1 tsp.)
Mix well then pour into an oiled 9"x13" pan (pyrex/glass seems to work best) and bake at 350°F for 40-50 minutes, or until a toothpick inserted comes out mostly clean. Remove and try to let cool for 20min or so before cutting into squares. Serve warm with ice-cream on top. Enjoy.
