I got this from them and thought maybe it should
be shared.

EBONIES

2 cups sugar
3 eggs
1/2 cup (1 stick) butter, melted
1/4 cup vegetable oil
2 teaspoons vanilla
1 cup King Arthur Unbleached All-Purpose Flour
1/4 teaspoon baking powder
1/2 teaspoon salt
1/2 cup Dutch-process black cocoa (avail. from King Arthur Flour)
1/4 cup Dutch-process or natural cocoa

In a medium-sized mixing bowl, beat together the
sugar, eggs, melted butter, vegetable oil and
vanilla until smooth. Stir in the dry ingredients (carefully -- as you know, cocoa tends to form a dark cloud over the mixer if you’re not gentle), stirring until everything is well-combined.

Scrape the batter into a lightly greased 9 x 9-inch
pan, and bake the brownies in a preheated 350°F oven
for about 35 minutes, until a tester inserted into the center comes out clean. Allow the brownies to cool in the pan until they’re just barely warm before cutting. Yield: about 16 delightful brownies.
