The Best Chocolate Cake Recipe Was Hiding on the Back of the Box

Cake ingredients: 2 cups white sugar 1 1/2 cups all-purpose flour 3/4 cup unsweetened cocoa powder 1-1/2 tsp baking soda  

1-1/2 tsp baking powder Add 1 tsp salt to 2 big eggs. 1 cup milk Half-cup vegetable oil Two teaspoons vanilla 1 cup boiling water  

Frosting: ¾ cup room-temperature unsalted butter 5.25 cups confectioners' sugar 1-1/2 cups unsweetened cocoa powder ⅔ cup milk 1 tsp vanilla  

Directions Start with a 350°F oven. Grease and flour two 9-inch circular pans.  

Make cake: Mix sugar, flour, cocoa, baking soda, baking powder, and salt in a bowl.  

Mix eggs, milk, oil, and vanilla for 3 minutes with an electric mixer. Stir boiling water by hand.  

Bake for 30–35 minutes in the preheated oven until a toothpick inserted into the centers comes out clean. Cool 10 minutes before removing from pans to finish cooling.  

Make frosting as cakes cool: Mix butter with an electric mixer until frothy. Mix confectioners' sugar, cocoa, milk, and vanilla. Beat to spreadable consistency.  

Divide the chilled cake horizontally, frost the tops, and place them on a serving platter.
