Classic chocolate cake

Preheat the oven to 350°F (175°C).

Grease and flour two 9-inch round cake pans or one 9x13 inch baking pan.

Mix together the dry ingredients: sugar, flour, cocoa powder, baking soda, baking powder, and salt.

Add the wet ingredients: eggs, milk, coffee, oil, and vanilla.

Beat with an electric mixer for about 2 minutes until the batter is smooth.

Pour the batter into the prepared pans.

Bake for 30-35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
