Step‑by‑Step Instructions for No-Bake Chocolate Peanut Butter Cornflake Squares
Step 1: Prepare Pan
Begin by greasing an 8″ square pan with cooking spray or a light coating of butter to prevent sticking. Make sure it’s evenly coated, so the squares release easily once they’re set. Set the pan aside while you move on to the next step, ensuring everything is ready for your delicious no-bake chocolate peanut butter cornflake squares.
Step 2: Heat Mixture
In a medium saucepan, combine creamy peanut butter, light corn syrup, and granulated sugar over medium-low heat. Stir this mixture gently until it warms up and becomes gooey, which should take about 4-5 minutes. Make sure everything is blended well for a smooth consistency, as this base will create the delicious foundation for your chocolate peanut butter cornflake squares.
Step 3: Combine Cornflakes
Once the mixture is warm and fully combined, remove it from the heat. Carefully fold in the crunchy cornflakes, ensuring each flake is well-coated with the peanut butter mixture. Use a spatula to gently mix everything together, taking care not to crush the cornflakes. Aim for an even coating, as this will give your no-bake chocolate peanut butter cornflake squares their signature crunch.
Step 4: Press Mixture
Transfer the cornflake mixture into the greased pan and use a measuring cup or spatula to press it down firmly. Compress the mixture to create a stable base that will hold together once cut. Make sure it’s evenly spread and packed tightly, which is crucial for the integrity of your no-bake chocolate peanut butter cornflake squares.
Step 5: Melt Topping
In a microwave-safe bowl, combine the chocolate chips and additional peanut butter. Microwave the mixture in 30-second intervals, stirring in between, until it melts smoothly, which should take about 1-2 minutes in total. Keep a close eye on it to ensure it doesn’t burn, then remove from the microwave once it’s velvety and well-blended.
Step 6: Spread Topping
Pour the luscious melted chocolate mixture over the pressed peanut butter cornflake base in the pan. Using a spatula, gently spread the chocolate evenly across the top, ensuring that it completely covers the base. This indulgent layer will turn your no-bake chocolate peanut butter cornflake squares into a decadent treat.
Step 7: Chill to Set
Allow the squares to set at room temperature for about 30 minutes, or place them in the refrigerator for quicker results. If refrigerating, let it chill until the chocolate hardens and the mixture firms up, making slicing easier and ensuring every bite is perfectly delightful.
Step 8: Slice and Serve
Once set, take the pan out of the fridge and use a sharp knife to cut the squares into equal pieces. Aim for bite-sized portions for easy serving. Now you’re ready to share these irresistible no-bake chocolate peanut butter cornflake squares with family and friends, offering a taste of nostalgia that everyone will enjoy!

Are these squares safe for people with nut allergies?
For those with nut allergies, I recommend substituting creamy peanut butter with sunflower seed butter or a nut-free alternative.
