1Heat oven to 350°F (if using dark or nonstick pan, heat oven to 325°F). Lightly grease bottom and sides of 13x9-inch pan with shortening or spray with cooking spray.
2In large bowl, beat brown sugar, butter, maple flavor and egg with electric mixer on medium speed, or mix with spoon. Stir in flour, baking soda, salt and 1/2 cup of the almonds. Pat dough in pan with lightly floured fingers.
3Bake 15 to 20 minutes or until golden brown. Cool completely, about 45 minutes.
4Meanwhile, in small bowl, stir all Maple Icing ingredients until smooth and thin enough to drizzle. Drizzle cooled bars with Maple Icing; sprinkle with remaining 1/4 cup almonds. Let stand 5 minutes or until set. For bars, cut into 6 rows by 4 rows.
