Chocolate Cake

Ingredients

¾ cup unsalted butter, room temperature

2 cups sugar

1 egg

2½ cups flour

1 teaspoon baking soda

½ cup cocoa powder

½ teaspoon salt

1 teaspoon vanilla

1½ cups water

2 scant tablespoons distilled white vinegar

Directions

Preheat oven to 350°. In a medium mixing bowl, beat together butter, sugar and egg. In another bowl, combine flour, baking soda, cocoa powder and salt. Stir with a fork to combine. Slowly add dry ingredients to the butter-sugar mixture and then add vanilla, water, and vinegar. Mix until well-combined.

Grease a 9"x13" baking tin and spread batter into an even layer. Bake for 20-30 minutes, until a toothpick inserted comes out clean.
