1 cup butter or margarine, melted
1 1/2 cups granulated sugar
2 eggs
1 teaspoon vanilla extract
1 1/4 cups all-purpose flour
2/3 cup unsweetened cocoa
1/4 cup milk
1 1/4 cups pecan pieces, divided
1/2 cup butter or margarine
1 (10 ounce) package peanut butter chips
1 (14 ounce) can sweetened condensed milk
1/4 cup semisweet chocolate chips

Preheat oven to 350 degrees F.

In a large bowl, combine melted butter, sugar, eggs and vanilla extract; beat well. Add flour, cocoa and milk; beat until blended. Stir in 1 cup pecans. Pour into a greased 13 x 9-inch baking pan. Bake for 25 to 30 minutes or just until edges begin to pull away from sides of pan. Cool completely in pan on wire rack.

In a medium saucepan over low heat, melt 1/2 cup butter and peanut butter chips, stirring constantly. Stir in sweetened condensed milk until smooth; pour over baked layer.

Place chocolate chips in a self-sealing plastic bag. Place in hot water in a microwave-safe bowl and microwave on HIGH for 45 seconds or until chips are melted when bag is pinched with fingers. Drizzle bars with melted chocolate; sprinkle with remaining pecans. Refrigerate 1 hour or until firm. Cut into bars.

Yields 2 dozen.
