1/2 stick butter, melted
2 cups (12-oz pkg) semi-sweet chocolate chips
1 can (14-oz) sweetened condensed milk
1 tsp vanilla extract
1 cup chopped pecans
Preheat oven to 350 degrees.
Combine the cookie crumbs and melter better until well mixed. Press onto the bottom of a 9 x 13-inch baking pan.
In a medium saucepan, over medium heat, melt 1 cup of the chocolate chips with the sweetened condensed milk. Stir in the vanilla. Pour this chocolate mixture evenly over the crust in the pan. Sprinkle the remaining cup of chocolate chips and the chopped pecans over the top.
Bake at 350 degrees for 20 minutes or until set. Cool in the pan on a wire rack. Cut into 24 large bars or 36 smaller bars.
These bars are good at room temperature or chilled.
