Kitchen Equipment Needed

Large mixing bowl
Saucepan
Wooden spoon or spatula
Baking sheet
Parchment paper or wax paper

Ingredients Overview

Cornflakes: The crispy base that gives these cookies their signature crunch.
Peanut Butter: Creamy peanut butter binds the cookies together and adds rich flavor.
Sugar: Sweetens the cookies and helps create the sticky coating.
Light Corn Syrup: Adds shine and helps hold the cookies together.
Vanilla Extract: Adds a touch of warmth and depth to the flavor.

Step-by-Step Instructions

1. Prepare the Baking Sheet

Line a baking sheet with parchment or wax paper to prevent sticking.

2. Heat the Peanut Butter Mixture

In a medium saucepan, combine 1 cup granulated sugar, 1 cup light corn syrup, and 1 cup creamy peanut butter.
Cook over medium heat, stirring constantly, until the mixture is smooth and just starts to bubble. Do not overcook, as this can cause the mixture to harden too much.

3. Add Vanilla

Remove the saucepan from heat and stir in 1 teaspoon vanilla extract.

4. Mix in Cornflakes

In a large mixing bowl, pour the peanut butter mixture over 6 cups of cornflakes. Gently fold until the cornflakes are evenly coated.

5. Form the Cookies

Using a spoon or cookie scoop, drop mounds of the mixture onto the prepared baking sheet. Work quickly, as the mixture sets fast.

6. Cool and Set

Allow the cookies to cool at room temperature for about 30 minutes, or until firm.

7. Serve and Enjoy

Once set, enjoy your crunchy, peanut buttery cookies!

Recipe Tips

Work quickly when forming the cookies, as the mixture can harden as it cools.
For added flavor, sprinkle the cookies with a pinch of sea salt or drizzle with melted chocolate.
