I've no idea why, but I have not served them without people requesting the recipe and rave reviews. I don't know the origin. It's just been passed on through my family.

Something went wrong. Our team is working on it. Original recipe (1X) yields 20 servings ½ cup peanut butter ½ cup brown sugar ½ cup corn syrup 2 cups cornflakes cereal 1 cup crispy rice cereal (such as Rice Krispies®) 2 cups confectioners' sugar 2 tablespoons custard powder ½ cup margarine, melted 1 tablespoon warm water, or as needed 4 (1 ounce) squares semisweet chocolate, chopped 2 tablespoons margarine Directions Grease an 8x8-inch square pan. Cook and stir peanut butter, brown sugar, and corn syrup together in a large pot over medium heat just until warm and well blended, about 3 minutes; remove from heat. Stir cornflakes cereal and crispy rice cereal into peanut butter mixture; press cereal mixture evenly into the prepared pan. Whisk confectioners' sugar and custard powder together in a bowl. Whisk 1/2 cup melted margarine gradually into custard mixture. Stir warm water into custard mixture to moisten to a spreadable consistency; spread evenly over cereal mixture. Melt chocolate with remaining 2 tablespoons margarine in a microwave-safe bowl, about 1 minute. Pour chocolate mixture over custard layer. Refrigerate cookies until chocolate is hardened, about 30 minutes; cut into 1-inch squares. Cook's Note: Can be made gluten-free by simply substituting both cereals with gluten-free versions.
