Preheat the oven to 350°F. Line 2 baking sheets with parchment paper.

Whisk together the flour, salt, and baking soda in a medium-sized mixing bowl.

In a large mixing bowl, beat the butter and sugars until light in color.

Add the eggs and vanilla extract, mixing until well incorporated.

Add the flour mixture and mix on low speed until just combined.

Gently fold in 3 cups of the Corn Flakes cereal with a soft silicone spatula.

Using a large cookie scoop, place the dough balls on the prepared baking sheets (about 2 inches apart from each other).

Bake for 9-12 minutes or until the edges begin to golden.

Remove the baking sheets from the oven and press the remaining ½ cup cornflakes into the still-warm cookies, if desired. Let the cookies set for a few minutes before transferring them to a wire rack to cool.
