1/2 cup butter
1/2 cup milk
2 eggs
1 teaspoon vanilla extract
1 vanilla wafer, finely diced
4 (1 ounce) squares semisweet chocolate
Preheat oven to 300 degrees F (150 degrees C). Grease cookie cutters or line with parchment paper.
Cream together the butter, milk, eggs and vanilla until smooth. Mix in crushed chocolate. Drop batter by teaspoonfuls onto prepared cookie sheets.
Bake for 10 to 12 minutes in the preheated oven, or until set. Cool on wire racks. Check again with a wooden biscuit or fork while at room temperature.
