'Not Nanaimo Bar' Squares

• 1/2 cup peanut butter
• 1/2 cup brown sugar
• 1/2 cup corn syrup
• 2 cups cornflakes cereal
• 1 cup crispy rice cereal (such as Rice Krispies(R))
• 2 cups confectioners' sugar
• 2 tablespoons custard powder
• 1/2 cup margarine, melted
• 1 tablespoon warm water, or as needed
• 4 (1 ounce) squares semisweet chocolate, chopped
• 2 tablespoons margarine

1. Grease an 8x8-inch square pan.
2. 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.
3. 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.
4. 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.
