1Heat oven to 350°F. In medium bowl, beat 3/4 cup butter, 1/2 cup brown sugar and the almond extract with electric mixer on medium-low speed until blended. On low speed, beat in flour until soft dough forms. Press dough in bottom of ungreased 13x9-inch pan. Bake 17 to 20 minutes or until golden brown.
2Meanwhile, in 2-quart saucepan, cook 1 cup butter, 1 1/2 cups brown sugar, the honey, corn syrup and vanilla over medium-high heat 12 to 15 minutes, stirring frequently, until mixture comes to a full rolling boil. Boil 1 to 2 minutes, stirring frequently. Remove from heat.
3Sprinkle walnuts, almonds and pecans over crust. Pour brown sugar mixture over nuts. Bake 13 to 15 minutes longer or until top of mixture is bubbly. Cool completely, about 1 hour. For bars, cut into 6 rows by 6 rows.
