Kitchen Equipment You’ll Need

• Large saucepan
  
• Mixing spoon or spatula
  
• Measuring cups and spoons
  
• Large mixing bowl
  
• Parchment paper or wax paper
  
• Cookie scoop (optional for even portions)

Step-by-Step Instructions

1. Prep Your Work Area

Line a baking sheet with parchment or wax paper. This is where the cookies will cool and set.

2. Heat the Peanut Butter Mixture

In a large saucepan over medium heat, combine sugar and light corn syrup. Stir until the sugar dissolves and the mixture just starts to bubble. Remove from heat and quickly stir in peanut butter until smooth.
Tip: Don’t let it boil too long, or the cookies will harden too much once cooled.

3. Add the Cornflakes

Pour the peanut butter mixture over the cornflakes in a large mixing bowl. Gently fold until all the flakes are coated. Try not to crush them too much — the big pieces keep the cookies extra crunchy.

4. Shape the Cookies

Scoop spoonfuls of the mixture onto the prepared baking sheet. Work quickly before the mixture sets. Press lightly into mounds with the back of a spoon.

5. Cool & Set

Let the cookies rest at room temperature until firm, about 30 minutes. Once set, they’re ready to enjoy!

Storage & Serving Tips

• Room temperature: Store in an airtight container for up to 1 week.
  
• Freezer: Freeze for up to 2 months. Thaw at room temperature before eating.
  
• Serving ideas: Great for lunchboxes, cookie trays, or even crumbled over ice cream.

FAQs

Can I use honey instead of corn syrup?
Yes, but the texture will be slightly softer and stickier.

Can I make these with crunchy peanut butter?
Absolutely! It adds more texture and nutty crunch.

Do they need to be refrigerated?
No, they set at room temperature and keep well in an airtight container.

Can I use a different cereal?
Yes, Rice Krispies or Special K work well, but cornflakes give the best crunch.

Why did my cookies turn out too hard?
You likely boiled the sugar mixture too long. Heat just until it bubbles, then remove.
