This Saltine Cracker Toffee was my grandma's recipe. It's addicting and one of my favorite treats!
Preheat oven to 400 degrees and line a cookie sheet with at least a 1/2 inch edge or jelly roll pan with parchment paper. Line saltine crackers in a single layer on the cookie sheet.
Bake at 400 degrees for 5 to 6 minutes. It will get all bubbly and the crackers will look like they are floating. Remove from oven and straighten any crackers that have gotten out of line. Sprinkle chocolate chips over the top and let sit a couple of minutes to melt. If your pan isn't hot enough you can even pop it back in the oven for a couple of minutes to melt them. Sometimes I melt the chocolate chips in the microwave for about 1 minute then spread it on. Spread melted chocolate and top with chopped nuts if desired. Cool completely. You can pop it in the fridge for a couple of minutes to help the chocolate set. Break into pieces and eat.
Note: You should either use salted butter or salted saltines but not both. I used salted crackers and unsalted butter in this one.
