Easy Toffee(Variations and Substitutions Are Listed at the End.)

Line a large cookie sheet with foil. Lay crackers on foil in a solid cover, crackers touching. Boil butter and brown sugar together for 3 minutes, stirring constantly. Pour over crackers, spreading to cover them all.

Bake at 400° for 5 to 7 minutes; do not allow sugar mixture to burn. Remove from oven and allow to sit about 3 minutes. Sprinkle chocolate chips evenly over candy and spread with a spatula or fork as chocolate begins to melt. Refrigerate. Chocolate will harden in about 30 minutes and candy can be broken into pieces (usually in 1 1/4-inch squares with a pizza cutter when candy just firms, for less crumbs).
