1 12-oz bag semi-sweet chocolate chips
1 cup finely chopped walnuts or pecans
2 14-oz cans sweetened condensed milk
1 1/2 teaspoons vanilla extract
1/2 teaspoon salt
2-3 cups powdered sugar
Combine graham cracker crumbs, chocolate chips, nuts, condensed milk, vanilla and salt in a large bowl and mix until well combined to make a batter. Batter will be THICK. Line a 3-quart 13x9 baking pan (or 2 8x8 square pans) with parchment paper (or aluminum foil greased well) then spread batter into pan(s). Bake at 350 degrees for 30 minutes or until set. Cool completely in pan, remove then cut into squares. Add powdered sugar to a medium bowl then add squares to sugar and toss to coat. Store in an air-tight container.
