This is recipe #2 of kingarthurflour.com Best Basic Recipe Collection. So easy to stir it together, bake, frost and serve right from the pan. Simple, simple! The one thing I would change next time I make this, is to make half the amount of icing. As you can tell from the photo there is plenty of frosting!
1½ cups flour
1 cup sugar
1/4 unsweetened cocoa
1/2 tsp salt
1/2 tsp espresso powder, optional
1 tsp baking soda
1 tsp vanilla
1 Tbl vinegar
1/3 cup oil
1 cup cold water
1½ cups semisweet chocolate chips
1/2 cup half-and-half
Preheat your oven to 350°F. Lightly grease an 8″ square or 9″ round pan that’s at least 2″ deep. Whisk the dry ingredients together in a medium-sized bowl. Whisk the vanilla, vinegar, vegetable oil, and water in a separate bowl. Pour the wet ingredients into the bowl of dry ingredients, stirring until thoroughly combined. Pour the batter into the prepared pan. Bake the cake for 30 to 35 minutes, until a toothpick inserted into the center comes out clean, or with a few moist crumbs clinging to it.
Serve the cake right from the pan; warm from the oven, it’s wonderful with a big glass of milk. Or, once cool, frost the cake with this simple chocolate frosting: Heat the chocolate chips with the half-and-half until the chips melt. Stir until smooth, and pour/spread over the cake. For a non-dairy icing, substitute 1/3 cup cold brewed coffee (or water) for the half-and-half.
