How to make Peanut Butter Cornflake Bars
To start making your Peanut Butter Cornflake Bars, gather all your ingredients and equipment, ensuring that everything is ready for a smooth preparation process. Begin by lining a square baking tin with nonstick baking paper. This is crucial because it makes removal of the bars easier once they have set, ensuring you get nice, clean edges. In a large saucepan, combine your creamy peanut butter and golden syrup or honey. Warm this mixture over medium heat, stirring constantly. The goal here is to melt them together to create a uniform mixture without overheating and burning.
Once the peanut butter and syrup are melted and well combined, remove the saucepan from the heat. The next step is crucial: add in the cornflakes and gently fold them into the mixture until they are fully coated. Take your time with this step to ensure that each cornflake gets the delicious peanut butter coating. After all the cornflakes are coated, spoon the mixture into your prepared baking tin. Press it down firmly and evenly to create a solid bar structure. The more firmly you pack it, the better the bars will hold together when cut.
After you have pressed the mixture into the tin, place it in the refrigerator to chill for 1 to 2 hours. This time allows the peanut butter mixture to set, resulting in bars that hold their shape well. Once set, remove from the fridge and cut the slab into 16 equal bars. You can store these in an airtight container in the refrigerator for up to three days, ensuring that they remain fresh and delicious.

How to serve Peanut Butter Cornflake Bars
Peanut Butter Cornflake Bars can be served in various delightful ways, making them versatile treats for different occasions. One of the simplest ways to enjoy them is straight out of the refrigerator for a refreshing snack. The chilled texture complements the crunch of the cornflakes and the creaminess of the peanut butter beautifully. If you’re feeling a bit indulgent, consider drizzling some melted dark chocolate over the top before slicing. This addition will provide an extra layer of richness and decadence that pairs wonderfully with the flavors already present.
These bars also make for a fantastic addition to lunchboxes, whether for kids heading off to school or adults bringing their meals to work. They are easy to pack and carry, providing a filling and energy-boosting option that can stave off hunger between meals. You could even serve them at gatherings, cut into smaller squares for bite-sized treats that everyone can enjoy. Pair them with a glass of milk or a cup of tea for a delightful afternoon snack.
How to store Peanut Butter Cornflake Bars
Proper storage of your Peanut Butter Cornflake Bars is crucial to maintaining their freshness and texture. Once they have completely cooled and set in the refrigerator, slice them into individual bars and transfer them to an airtight container. It is advisable to layer the bars with parchment paper to prevent them from sticking together, especially since the peanut butter may soften slightly after being out of the fridge.
You can keep these bars in the refrigerator for up to three days without losing flavor or texture. However, if you want to store them for a longer period, consider freezing them. Wrap each bar tightly in plastic wrap and then place them in a freezer-safe container or a resealable bag. They can be kept frozen for up to two months. When you’re ready to enjoy one, just remove it from the freezer and let it thaw at room temperature for about 30 minutes, and you’ll have a delicious treat ready to eat.
Tips to make Peanut Butter Cornflake Bars
To achieve the best possible results with your Peanut Butter Cornflake Bars, consider a few handy tips. First, ensure that your peanut butter is of good quality for the best flavor and texture. If you’re using a natural peanut butter, ensure that it’s well mixed before measuring, as the oil can separate. Another essential tip is to measure your cornflakes accurately; too much or too little can change the texture of the bars significantly.
When it comes to pressing the mixture into the tin, using a flat-bottomed spatula or even a piece of parchment paper can make this task much easier, allowing you to evenly distribute the pressure without sticking. Experimenting with additional ingredients is also a fun way to personalize the bars. You could mix in nuts, seeds, or dried fruit for added texture and flavor giving each bite a unique twist.
