Heat oven to 325.

In a large bowl, beat butter and brown sugar with electric mixer until light and fluffy. Add egg and vanilla, beat until blended. Add flour, graham cracker crumbs and salt, beat on low speed about 1 minute or until a stiff dough forms.

Shape dough into heaping teaspoon size balls. Place on an ungreased cookie sheet at least 2 inches apart. With thumb, make indentation in center of each.

Bake 10-12 minutes or until cookies are firm and edges are just beginning to brown. Lightly press 2 marshmallows in the center of each cookie, bake 2-3 minutes longer. Top marshmallows on each cookie with a rectangle of chocolate, let stand 2-3 minutes. With a tip of a knife, spread the melting chocolate over marshmallows. Let stand until chocolate is set.
