2Place the flour, salt, and baking powder in a large bowl. In a separate bowl, cream together the sugar, egg, and butter until smooth. Mix the powdered milk, water, and vanilla into the batter, stirring until well blended. Pour the batter into the flour and beat until smooth.
3Spread the batter into a greased 8 inch square pan, and sprinkle the diced apricots evenly over the top. Dust with cinnamon and sugar.
4Bake in the preheated oven approximately 45 minutes, or until a toothpick inserted into the center of the cake comes out clean.
