This crust gives extra sweetness to any pie.
In a large bowl, sift together flour and cocoa powder. Set aside.
In small bowl, using a fork, combine remaining ingredients; add to cocoa mixture. Rub mixture with fingers until it holds together without large lumps of butter remaining. Turn mixture onto clean surface; knead until smooth, about 1 minute. Form into disc, wrap in plastic; chill 30 minutes.
