Here's a really easy one to make that is like a heath bar.
Fool’s Toffee
36 to 40 saltine crackers (1 sleeve)
1 cup (2 sticks) real butter
1 cup packed dark brown sugar
2 cups (12 oz.) milk chocolate chips
½ to 1 cup chopped pecans
Line a 10x17 inch-baking pan with foil and coat the foil with butter. Arrange the crackers in a single layer with sides touching in the prepared pan. Combine 1 cup butter and brown sugar in a saucepan. Bring to a boil over medium heat, stirring constantly. Boil for 4 minutes, stirring constantly.
Pour the butter mixture over the crackers. Using a wooden spoon spread the mixture evenly over the crackers. Bake at 350 degrees for 5 minutes. Sprinkle with the chocolate chips and let stand for 2 minutes or until the chips soften. Spread the chocolate evenly over the prepared layers. Sprinkle with pecans and press lightly. Chill for 30 minutes or until set. Break into pieces and store in a covered container in the refrigerator.
