Step‑by‑Step Instructions for No-Bake Chocolate Peanut Butter Cornflake Squares
Step 1: Prepare the Pan
Start by greasing an 8-inch square pan with cooking spray or butter to prevent sticking. Make sure to spread it evenly across the base and sides, creating a non-stick surface for your delicious No-Bake Chocolate Peanut Butter Cornflake Squares. Set the prepared pan aside while you move on to the next step.
Step 2: Heat the Base Ingredients
In a medium saucepan, combine 1 cup of creamy peanut butter, 1/2 cup of light corn syrup, and 1/2 cup of granulated sugar over medium-low heat. Stir continuously with a wooden spoon for about 5 minutes until the mixture becomes smooth and gooey, ensuring all elements are well blended and the sugar is dissolved. Remove from heat once it reaches a lovely homogeneous consistency.
Step 3: Mix in Cornflakes
Remove the saucepan from the heat and gently fold in 4 cups of cornflakes. Use a spatula to ensure each flake is fully coated with the warm peanut butter mixture, which should create a clumpy, sticky texture. Be careful not to crush the cornflakes as you mix; you want the satisfying crunch to remain intact for your No-Bake Chocolate Peanut Butter Cornflake Squares.
Step 4: Transfer & Press
Pour the cornflake mixture into your greased pan, spreading it out evenly with a spatula. Then, using the bottom of a measuring cup, press the mixture down firmly into the pan to create a solid, compact base. This step is crucial to ensuring your squares hold together once set, so take time to press it firmly yet gently.
Step 5: Melt Chocolate Topping
In a microwave-safe bowl, combine 1 cup of chocolate chips with 1/4 cup of additional creamy peanut butter. Microwave in 30-second intervals, stirring in between until melted and smooth, which should take about 1 to 1.5 minutes total. Keep a close eye on it to avoid scorching; you want a luxurious chocolate topping for your squares.
Step 6: Spread Topping
Once melted, carefully pour the chocolate mixture over the pressed cornflake base. Use a spatula to evenly spread the luscious chocolate peanut butter topping across the surface, ensuring every corner is covered. This layer should be thick and rich, providing a delightful contrast to the crunchy bottom layer of your No-Bake Chocolate Peanut Butter Cornflake Squares.
Step 7: Chill to Set
Let your creation sit at room temperature for about 10-15 minutes before refrigerating. If you prefer a firmer texture, place the pan in the fridge for around 30 minutes. During this time, the chocolate will set beautifully, becoming the perfect finish to your delicious treat.
Step 8: Slice & Serve
Once set, remove the squares from the pan using a sharp knife and cut them into small squares or rectangles, depending on your preference. Serve immediately, or enjoy them later as a sweet snack or dessert. The delightful combination of peanut butter, chocolate, and cornflakes in your No-Bake Chocolate Peanut Butter Cornflake Squares is sure to be a favorite among friends and family!
