1Heat oven to 375°F (if using dark or nonstick pan, heat oven to 350°F). Grease bottom and sides of 15x10x1-inch pan with shortening or spray with cooking spray.
2In large bowl, beat 3/4 cup butter and the granulated sugar with electric mixer on medium speed until light and fluffy. Beat in egg. Beat in flour on medium speed until dough starts to form. Press dough in pan. Bake 13 to 18 minutes or until edges are light golden brown.
3Meanwhile, in 2-quart heavy saucepan, heat 1 cup butter, the brown sugar and corn syrup to boiling over medium heat, stirring frequently. Boil 2 minutes without stirring. Quickly stir in almonds; spread over baked layer. Bake 15 to 20 minutes or until dark golden brown and bubbling.
4Immediately sprinkle chocolate chips evenly over hot bars. Let stand 5 minutes to soften; gently swirl chips over hot bars with spatula. Cool completely, about 30 minutes. For bars, cut into 8 rows by 5 rows. Store tightly covered at room temperature.
