My family's favorite and very easy to make.
Melt margarine in an ungreased 9x13 baking pan in oven set at 350.
After margarine is melted evenly spread graham cracker crumbs over the bottom of the pan.
Add next three ingredients evenly over the crumbs.
Pour condensed milk evenly over the top, then sprinkle on the nuts.
Press mixture down into pan gently with a spoon.
Bake at 350 for 25-30 mins. or until the edges start turning brown.
Let cool and cut into small bars. My family's favorite and very easy to make
