*FOR HOUSES*
Grease and flour an 17x11-inch jelly roll pan. Turn dough out onto lightly floured board or pastry cloth and knead until smooth and pliable. Roll out dough in prepared pan as evenly as possible, forcing dough into corners of pan with fingers if necessary. Bake for 15 minutes or until deep brown and firm to the touch. Cool in pan for 5 minutes. Cut pieces using patterns and small sharp knife. It is important to cut pieces while cake is very warm because gingerbread hardens as it cools. Cool pieces on wire racks.
*FOR COOKIES*
Roll out a small amount of dough to 1/8-inch thickness on lightly floured board or pastry cloth. Keep remaining dough refrigerated until ready to use. Cut out cookies with shaped cutters; arrange one inch apart on ungreased baking sheet. Bake for 10 to 12 minutes or until deep golden brown. Cool on wire racks. Decorate with Decorator Icing and trims as desired.
