Chewy-meets-crispy no-bake cookies made from creamy peanut butter, light corn syrup, and crunchy cornflakes. They come together on the stovetop in minutes—perfect for lunchboxes, holidays, or anytime snacking.
Line a baking sheet with parchment paper and set aside.
In a medium saucepan over medium heat, stir the granulated sugar and light corn syrup until the sugar dissolves and the mixture reaches a gentle simmer.
Remove the pan from heat and immediately stir in the peanut butter and vanilla extract until smooth and glossy.
Gently fold in the cornflakes until all flakes are evenly coated. If using salt, add a small pinch now and fold again.
Working quickly, drop spoonfuls (or use a cookie scoop) of the mixture onto the prepared baking sheet, shaping into cookies.
Let the cookies cool and set at room temperature for about 30 minutes before serving.
