Cream butter and sugar. Beat in eggs until smooth. Sift together flour and baking powder, add to butter mixture alternately with milk. Mix until well blended. Wrap and chill dough 3 hours or more.

Preheat oven to 350 degrees. Divide dough into thirds. Roll each section to 1/8 inch thickness. Cut shapes and place on parchment-covered baking sheet. Bake until golden, about 10-12 minutes. Cool on racks.
