This is my tried and true recipe for "Saltine Toffee" I make it every year
1 sleeve salted saltine crackers
Cover cookie sheet with foil, and non stick spray. Line crackers on the sheet, fill to edge with crackers (even if you have to break them in half)
In pan melt 1 stick salted butter, and 1 cup packed brown sugar. Bring to a boil. I stir gently with a wooden spoon while it's melting.
Heat oven to 350
.Pour hot mixture (and be careful, it is VERY HOT) evenly over the crackers. Spread with a knife if necessary. Bake for 10 min. Cool 1 min and then spread 1 bag of chocolate chips over the toffee. Return to the oven for 1 min or so until chocolate is just about all melted. Spread chocolate evenly with a knife or spatula to even it out. Sprinkle with chopped nuts. (I use a combination sometimes of nuts, craisins and raisins on one of the trays, just for variety). Store in an airtight container
I usually end up making at least 2-3 trays at it disappears very quickly, lol!
