Cream butter and sugar. Beat in eggs, vanilla and extract until light and fluffy. In separate bowl combine flours and baking soda. Whisk them together thoroughly. Gradually stir flour mixture into egg mixture until blended. Divide into 4 equal pieces and shape into 4 logs using wax paper or plastic wrap. Wrap air tight and place in an air tight plastic container in your freezer.
To bake 1 roll of dough:
Preheat oven to 350. Lightly grease baking sheets or use silicon baking mat on cookie sheet(my preference). Cut frozen dough 1/4″ thick. Place slices on baking sheet about 1/2″ apart. Bake 8-10 minutes or more if you like them crispy. Remove from cookie sheets and cool on wire rack.
*If you bake them less and keep them soft they are perfect for ice cream sandwiches.
