1Preheat oven to 400 degrees F. Line a 15 x 10 x 1-inch jellyroll pan with tin foil. Lightly spray foil with a non-stick cooking spray.
Place saltine crackers, salty side up, in prepared pan. In a saucepan, boil butter and sugar for 2 to 3 minutes, stirring constantly. Remove from heat and stir in almond extract. Pour mixture over crackers and bake for 4 to 6 minutes. Remove from oven, top with candy bars, and spread evenly as chocolate begins to melt. Cool slightly and transfer onto wax paper. Allow to cool completely.
