Preheat oven to 400°. Line a 10×15 inch cookie sheet with aluminum foil.
Place crackers in a singe layer over prepared cookie sheet. Use more or fewer crackers as needed to cover the bottom of your pan.
In a small saucepan over low heat combine butter and brown sugar; bring to a boil. Boil for 3 minutes; pour over crackers. Bake in preheated oven for 5 minutes. Sprinkle chocolate chips evenly over the top. Sprinkle almonds over chocolate chips; using the back of a wooden spoon, press nuts into chocolate.
Chill in refrigerator for at least 3 hours, or until set. Break into pieces and store, sealed, in refrigerator.
