1Heat oven to 375°F. In large bowl, beat butter and almond paste with electric mixer on medium speed until well blended. Beat in egg until well blended. Stir in cookie mix and 1 tablespoon water until soft dough forms.
2Using cookie scoop (2-tablespoon size), drop dough by level scoopfuls 2 inches apart onto ungreased cookie sheets. Press 1 almond in center of each mound of dough.
3Bake 12 to 14 minutes or until edges are light golden brown. Cool 1 minute; remove from cookie sheets to cooling rack. Cool completely, about 15 minutes.
4In small bowl, mix icing ingredients until smooth. Drizzle icing over cookies.
