Layered Cookie Bars

3/4 cup (1 1/2 sticks) butter or margarine
1 3/4 cups vanilla wafer crumbs (about 50 wafers, crushed)
6 tablespoons Cocoa powder
3/4 cup sugar
1 can (14 ounces) sweetened condensed milk (not evaporated)
1 cup Chocolate chips
3/4 cup toffee bits
1 cup chopped walnuts

1. Heat oven to 350 degrees. Melt butter in 13X9X2 inch baking pan in oven. Combine crumbs, cocoa, and sugar; sprinkle over butter.
2. Pour sweetened condensed milk evenly on top of crumbs. Top with chocolate chips and toffee bits, then nuts; press down firmly.
3. Bake 25 to 30 minutes or until lightly browned. Cool completely in pan on wire rack. Chill, if desired. Cut into bars. Store covered at room temperature.

Tips:
Make sure to use unsalted butter. But you can add like a 1/4 teaspoon of salt to even out the sweetness.
Also, I didn't use toffee bits or walnuts. I just used some crushed almonds, and it still tasted great! :)
