Not only does this cake not require a mixer, but the entire thing is made directly in the 9x13 baking pan. Just dump all of your ingredients in the pan and mix them right there — talk about an easy one-pan dessert. Top the cake with your favorite frosting and, of course, some crazy sprinkles.
3 cups all-purpose flour
2 cups white sugar
½ cup unsweetened cocoa powder
2 teaspoons baking soda
1 teaspoon salt
¾ cup vegetable oil
2 tablespoons distilled white vinegar
2 teaspoons vanilla extract
2 cups cold water
Preheat the oven to 350 degrees F (175 degrees C).
Sift flour, sugar, cocoa, baking soda, and salt into a 9x13-inch ungreased baking dish; form 3 wells in flour mixture. Pour oil into the first well, vinegar into the second, and vanilla into the third. Pour cold water over all and stir well with a fork.
Bake in the preheated oven until a toothpick inserted into the center of the cake comes out clean, 30 to 40 minutes. Frost with your favorite icing.
