How to Make Peanut Butter Cornflake Bars

Prepare the Pan: Start by spraying a 9×13-inch baking pan with vegetable oil spray. This helps the bars release easily once they’ve cooled and ensures a perfect slice every time.
Heat the Mixture: In a medium saucepan, combine the creamy peanut butter, light corn syrup, and sugar. Heat over medium, stirring continuously until the mixture is well blended and just dissolved—this should take about 3-5 minutes.
Combine and Mix: Remove the saucepan from heat and pour the warm peanut butter mixture over 6 cups of cornflakes in a large bowl. Stir gently to coat each flake evenly, ensuring every bite will be sweet and crunchy.
Press into Pan: Using a spatula or your hands, gently press the cornflake mixture into the prepared baking pan. Make sure to spread it out evenly to achieve uniform bars once sliced.
Cool Completely: Allow the bars to cool completely at room temperature, which may take about 30 minutes. This step is essential for the bars to set properly and holds together when cut.
Slice and Serve: Once cooled, slice into squares or rectangles as desired. Enjoy these delightful Peanut Butter Cornflake Bars as a treat, snack, or dessert!

Expert Tips for Peanut Butter Cornflake Bars

• Smooth Peanut Butter: Choose creamy peanut butter for a velvety texture. Natural varieties with oils on top can make the mixture too runny.

• Even Mixing: Ensure the cornflakes are evenly coated with the peanut butter mixture. Gently fold the mixture rather than stirring aggressively to avoid crushing them.

• Cooling Time: Allow the bars to cool completely before slicing. If you’re in a hurry, refrigerating for 15-20 minutes can speed up the process without compromising texture.

• Perfect Cutting: For cleaner cuts, use a sharp knife. Wipe it with a damp cloth between slices to prevent sticking.

• Storage Tips: Store any leftovers in an airtight container at room temperature for up to a week, or refrigerate for longer freshness. Enjoy your Peanut Butter Cornflake Bars any time!

Peanut Butter Cornflake Bars Recipe FAQs

What type of cornflakes should I use for the Peanut Butter Cornflake Bars?
Absolutely! You can use any brand of cornflakes you prefer. I recommend sticking to classic, crunchy cornflakes as they provide the perfect texture and stability for the bars. Avoid flavored varieties, as they could alter the deliciously sweet and salty taste you want in your bars.

How long can I store Peanut Butter Cornflake Bars?
Store the bars in an airtight container at room temperature for up to 5 days to retain their delicious crunch. If you’d like them to last longer, refrigerating them extends their freshness to about 2 weeks. Remember to separate layers with parchment paper to prevent sticking!

Can I freeze Peanut Butter Cornflake Bars?
Absolutely! For freezing, tightly wrap each bar in plastic wrap and place them in an airtight container. They can stay fresh in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw them at room temperature for about 30 minutes, or you can microwave them for 10-15 seconds for that delightful chewy texture.

What should I do if my bars are too sticky?
If your bars turn out too sticky, it may be due to too much peanut butter or corn syrup. To rescue them, try chilling the bars in the fridge for at least 30 minutes to let them firm up. If you prefer a less sticky texture next time, you can reduce the amount of corn syrup slightly for a firmer result.

Are there any dietary considerations for Peanut Butter Cornflake Bars?
Yes! These bars are not suitable for those with peanut allergies, but you can easily swap the peanut butter for a nut-free alternative, like sunflower seed butter, to make them allergen-friendly. Just check the labels to ensure all ingredients align with your dietary needs.

The more the merrier! You can mix in chocolate chips, dried fruits like cranberries or raisins, or even add a dash of cinnamon for an extra flavor kick. Just ensure the total volume remains similar so they hold together well.
