Bake for 30 minutes or until a cake tester inserted into the center comes out clean.
Allow to cool before frosting.
Frosting
In a medium bowl, mix powdered sugar and butter with a mixer on low speed.
Stir in vanilla and 1 tablespoon of milk.
Gradually mix in additional tablespoon of milk until the frosting is smooth and spreadable.
If frosting is too thick, add more milk, a few drops at a time.
If frosting is too thin, gradually add small amounts of powdered sugar until thickened.
Notes
Pan Trick: Use shiny cake pans if you have them, dark pans can dry out the cake.
Enhance the Flavor: Add cayenne pepper or expresso powder or brewed coffee for a unique flavor.
Chocolate Surprise: Try upping the chocolate. More chocolate to the cake, dark, milk, white or semi sweet chocolate will add extra moisture and flavor.
