Preheat oven to 375 degrees.

Combine all ingredients and mix well.

Roll dough into balls.

Pour the extra ½ cup of sugar in a shallow bowl or plate.

Roll cookie dough in sugar until completely covered.

Place on cookie sheet and bake for 8-10 minutes until just before turning brown.

While the cookies are baking, unwrap chocolate hearts.

Remove cookies from oven, gently press a chocolate heart in the center of each cookie and let cool (may use substitute Hershey's Kisses).

Allow to cool completely then melt ¼ cup white chocolate chips in a glass bowl on medium power setting in 30 second intervals until melted.

Dip the end of a spoon in the melted white chocolate chips, then sling back and forth on the tops of cookies (optional).
