'Not Nanaimo Bar' Squares


Growing up for some reason we referred to these as 'Oh Henry Squares'. 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.

  • 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


  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.

Cook's Note:

Can be made gluten-free by simply substituting both cereals with gluten-free versions.
