Heat your oven to 400 degrees.

Lay a single layer of saltines on a 10x15 inch cookie sheet with edges.

Place the butter and sugar in a small saucepan. Stir frequently until the mixture comes to a boil. Let boil for 3 minutes, continuing to stir.

Pour the hot mixture over the saltines.

Bake for 7 minutes, then remove from the oven, and cover with chocolate chips.

After about 5 minutes the chocolate chips will be melted and you can use a knife to evenly spread out the chocolate.

Top with the chopped nuts.

Mom says to take a metal spatula and to run it around the edges of the pan to help loosen it up after 15 minutes. Be very careful since it's still very hot.

Once the bark has cooled completely, break it into pieces.
