Directions Preheat oven to 350 degrees. In an 8-inch square baking pan, whisk together flour, sugar, cocoa powder, baking soda, and salt. Make a well in center of flour mixture and add oil, vanilla, vinegar, and water. Whisk until well combined. Bake until a toothpick inserted in center comes out clean, 35 to 40 minutes. Let cool completely in pan on a wire rack. Credit: Johnny Miller Variations To frost this cake, make a batch of simple buttercream: Sift 1/2 pound confectioners' sugar. In the bowl of an electric mixer fitted with the paddle attachment, combine sifted sugar with 1 cup (2 sticks) room-temperature unsalted butter, 1/2 teaspoon pure vanilla extract, and a pinch of kosher salt. Beat on high speed 2 to 3 minutes, scraping down sides of bowl as needed.
