1Cream butter and sugar. Add egg and beat. Add milk and vanilla. Add rest of ingredients and mix well.
Roll out dough to 1/8" thick. Cut the dough with solid shape cookie cutters such as hearts, christmas trees, etc. With very small cookie cutter of same shape, cut out centers of half of the shapes. (The outside edge pieces go on top of the solid shapes). Gather up bits of cut-out centers and roll out again, repeating til all dough is used up. Place whole shapes onto ungreased cookie sheet.
Top each cookie center with a teaspoons or so of strawberry jam. (Or flavor(s) of your choice.) Place cookie shape with cut-out center on top.
Seal outside edges all the way around with tines of fork. Pressing to seal. Decorate as you like such as sprinkling edges with colored sugar. Press little candy silver balls at intervals around inside edge evenly, if desired. Bake in 350° oven for 11-13 minutes. These do not brown. When cool, other decorating options are to sprinkle them with powdered sugar or drizzle with melted chocolate. Just have fun! :D Enjoy!
