Author Notes

One of my oldest and dearest friends in the world makes this cake for Groom every year on his birthday. Or if someone just needs a lift. Or if she just needs a lift. The chocolate buttercream is lucky to make it onto the cake. Add this one to your repetoire. It's a showstopper. Everytime. —Feeding Groom

Put the confectioner's sugar, milk, vanilla, salt in bowl and beat with mixer on low speed til the frosting lightens and is fluffy. Add more milk if it’s too thick and more confectioner’s sugar if too thin. Makes plenty to fill and frost the three layer cake.
