Pecan Turtles® Bars

1 ½ cups all-purpose flour

1 ½ cups brown sugar, divided

½ cup butter, softened

1 cup pecan halves

⅔ cup butter

1 cup milk chocolate chips

Preheat oven to 350 degrees F (175 degrees C).

Combine flour, 1 cup brown sugar, and softened butter in large mixer bowl. Beat at medium speed for 2 to 3 minutes or until mixture resembles fine crumbs. Pat mixture evenly onto bottom of ungreased 13x9-inch baking pan. Sprinkle pecans evenly over crumb mixture.

Combine 2/3 cup butter and remaining 1/2 cup brown sugar in small saucepan. Cook and stir over medium heat until entire surface is bubbly; cook, stirring constantly, 1/2 to 1 minute more. Pour into pan, spreading evenly over crust.

Bake in preheated oven until entire surface is bubbly, 18 to 20 minutes. Remove from oven; immediately sprinkle with chocolate pieces. Let stand 2 to 3 minutes to allow chocolate to melt; use a knife or small spatula to swirl chocolate slightly. Cool completely in pan on a wire rack. Use sharp knife to cut into 48 bars.
