Chocolate Dipped Macadamia Nut Shortbread

1 cup butter, softened
3/4 cup confectioners' sugar
2 cups flour, sifted
1 1/2 teaspoons shortening
1 teaspoon vanilla extract
1 cup macadamia nuts, coarsely chopped
1/4 cup macadamia nuts, finely chopped
1 cup chocolate chips

In large bowl, cream butter, sugar and vanilla extract together. Slowly stir in flour until well blended. Add coarsely chopped macadamia nuts.

On wax paper shape cookie dough into a roll approximately two inches in diameter. Roll wax paper around dough then wrap the roll in aluminum foil. Place in refrigerator, chilling at least 2 hours or more.

Heat oven to 300 degrees F.

Remove chilled cookie dough and cut roll into slices between 1/4 and 1/2 inch thick. Place on ungreased cookie sheet and bake for approximately 20 minutes or until they turn golden brown around the edges.

While cookies cool on a wire rack, pour 1/4 cup finely chopped macadamia nuts into small bowl. Melt chocolate chips in a bowl in microwave. Add shortening to warm, melted chocolate chips, blending well. Dip one end of each cookie into chocolate, then into the finely chopped macadamia nuts and place on wax paper. Refrigerate cookies until chocolate hardens. Store in cool place.
