Sweetheart Cookie Puzzle

1 cup butter or margarine, softened
1 cup granulated sugar
2 teaspoons vanilla extract
2 cups uncooked rolled oats
1 1/4 cups unbleached flour
2 cups M&M's plain chocolate candy

Preheat oven to 350 degrees F. Lightly spray 2 baking sheets with cooking spray; set aside.

In a mixing bowl, combine butter, sugar and vanilla extract.

In another mixing bowl, combine oats and flour.

Mix wet ingredients with dry ingredients just until moistened. Divide dough in half.

Pat each half of dough into heart shape about 1/4-inch thick on prepared baking sheets.

To decorate, gently press M&M's into dough in a pattern or phrase of your choice. With a sharp knife, cut through dough to form 10 random shapes. Do not separate.

Bake for 15 to 18 minutes or until lightly browned. Carefully cut through pieces again to separate.

Cool 5 minutes on baking sheet. Remove and cool completely on wire rack.
