Brown Sugar Cookies

1/2 cup butter (I use salted at room temperature)
1 cup light brown sugar (firmly packed)
1 tablespoon grated orange rind
a drop of orange food coloring (or one drop of red and one of yellow

1 egg (at room temperature)
1 teaspoon vanilla extract
2 cups sifted all purpose flour
2 teaspoons double-acting baking powder
1/4 teaspoon salt

Cream butter and brown sugar.  Add orange rind, food coloring, and egg, beating until smooth.  Stir in the vanilla.  Combine the flour, baking powder, and salt.  Slowly add flour mixture until just mixed.  
Roll out dough 1/8 inch thick on lightly floured surface, cut into shapes with floured cookie cutters (I refrigerate dough overnight before rolling and baking).  Bake at 350 degrees or 12-15 minutes on greased cookie sheets.  Makes approximately 3 dozen cookies.
Recipe is from a Domino Golden Light Brown Sugar box from long ago.
