- 1 1/4 cups butter, softened
- 1 cup sugar
- 2/3 cup confectioners' sugar
- 1 egg
- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1/4 teaspoon salt
- 1/4 cup baking cocoa
- In a large mixing bowl, cream butter and sugars. Beat in egg and vanilla. Combine flour and salt; gradually add to the creamed mixture. Divide dough in half. Add cocoa to one half; mix well. Roll each half between waxed paper into a 9-in. square. Cut both squares into three 3-in. strips. Cut the strips in half lengthwise to make six 4-1/2-in. x 3-in. rectangles.
- Place one cream-colored rectangle on a large piece of plastic wrap; top with a chocolate rectangle. Repeat layers twice. Wrap in plastic wrap and refrigerate for 2 hours. Unwrap and cut widthwise into eighteen 1/4-in. slices.
- Cut each slice with a horse-shaped cookie cutter dipped in flour. Place 1 in. apart on ungreased baking sheets. Bake at 375 degrees F for 8-10 minutes or until edges are lightly golden. Let stand for 2 minutes before removing to wire racks to cool.
