1 pkg. (10 oz.) mint flavored semi-sweet chocolate morsels, yield 1 1/2 c., divided
3/4 c. butter, softened
1/3 c. sugar
1/2 tsp. salt
1 egg
1 tsp. vanilla
2 1/4 c. all-purpose flour

In small saucepan over low heat, melt 1/2 cup mint flavored semi-sweet chocolate morsels, stirring until smooth. Set aside. In large mixer bowl, beat butter, sugar and salt until creamy. Beat in egg and vanilla extract (mixture may appear curdled). Gradually add flour.

Place 1 cup dough in bowl; blend in melted morsels. Shape chocolate and plain doughs into balls; flatten and wrap in plastic wrap. Refrigerate about 1 1/2 hours until firm. Preheat oven to 375 degrees. Between sheets of wax paper, roll each ball of dough into 13x9 inch rectangle. Remove top layers of wax paper. Invert chocolate dough onto plain dough. Peel off wax paper. Starting with long side, roll up jelly roll style. Cut into 1/4 inch slices; place on ungreased cookie sheets.

Bake 7 to 10 minutes until set. Let stand 2 minutes. Remove from cookie sheets; cool.

In small saucepan over low heat, melt remaining 1 cup chocolate morsels, stirring until smooth. Spread flat side of each cookie with slightly rounded 1/2 teaspoonfuls chocolate. Refrigerate 10 minutes to set chocolate. Makes 3 1/2 dozen.
