Blend sugar, butter, eggs and vanilla extract with electric mixer until fluffy. Sift together flour, cocoa and salt; set aside.

Combine vinegar and milk. Alternately, add dry and liquid mixtures to first mixture.

Combine baking soda and boiling water; add to mixture. Mix thoroughly; batter will be thinner than for most cakes. Bake in a 13 x 9-inch pan at 350 degrees F for 35 to 45 minutes. Frost while still warm.
