Instructions

Prepare the Baking Sheet: Line a baking sheet with parchment paper to prevent the cookies from sticking and ensure easy removal once set.
Melt and Mix the Wet Ingredients: In a medium saucepan over low-medium heat, combine the sugar, corn syrup, butter, and creamy peanut butter. Stir continuously with a spatula until the mixture begins to boil. As soon as it reaches a boil, remove the pan from heat immediately to prevent burning, then stir in the vanilla extract and salt for flavor balance.
Incorporate the Cornflakes: Gently fold the cornflake cereal into the warm peanut butter mixture, taking extra care not to crush the flakes. Make sure every flake is evenly coated with the sticky mixture to ensure consistent texture and sweetness.
Shape the Cookies: Lightly spray a small cookie scoop with non-stick spray to prevent sticking, then scoop the mixture onto the prepared baking sheet. If preferred, gently flatten the cookies to your desired thickness and shape for uniform baking and presentation.
Set the Cookies: Allow the cookies to set at room temperature for about 30 minutes or until firm to the touch. This resting period helps the cookies solidify without requiring baking.

Notes

You can substitute light corn syrup with mini marshmallows for a slightly different texture and sweetness.
Butter is optional but adds richness and a smoother texture to the cookies.
Handle the cornflakes gently to maintain their crunchiness in the final cookie.
Ensure the mixture reaches a boil to properly combine ingredients and create the right texture.
Store cookies in an airtight container at room temperature for up to 3 days to maintain freshness.
