Ingredients

  • 1 c. sugar
  • 2/3 c. syrup
  • 1 c. peanut butter
  • 2 c. corn flakes

Instructions

  1. Put sugar and syrup into a pan and let come to a boil.
  2. Add peanut butter and stir until melted.
  3. Pour this mixture over corn flakes and mix rapidly.
  4. Flatten the mixture out on a greased cookie sheet.
  5. Cool and cut into 1 1/2-inch squares.

Tips & Substitutions

For a crunchier texture, try replacing some corn flakes with puffed rice or add chopped nuts for extra flavor. If you're looking to reduce sugar, consider using a sugar substitute that measures like sugar. Be sure to stir the mixture quickly after adding the peanut butter, as it can firm up fast, making it harder to coat the corn flakes evenly.

Serving Suggestions

These fast cookies are delightful on their own or can be served with a glass of milk or tea for a comforting snack. They also pair beautifully with Homemade Ice Cream Mix for a fun dessert. For a festive touch, drizzle melted chocolate over the top before cooling, adding an extra layer of flavor.

Storage & Reheating

Store leftover cookies in an airtight container at room temperature for up to a week. To keep them fresh, you can also refrigerate them, but allow them to come to room temperature before serving, as they may harden in the fridge. If you want to enjoy them warm, briefly microwave individual squares for about 10 seconds.

Frequently Asked Questions

Can I use a different type of nut butter?

Yes, you can substitute peanut butter with almond butter, cashew butter, or sunflower seed butter for a different flavor profile or to accommodate allergies. Just ensure the consistency is similar to peanut butter for optimal mixing and binding.

How do I know when the sugar and syrup mixture is ready?

The mixture is ready when it reaches a full boil, which usually takes about 3-5 minutes. You can check by watching for bubbles that break the surface continuously. Avoid overcooking, as it can become too thick once cooled.

Can I add chocolate chips to the cookies?

Absolutely! Adding chocolate chips is a great way to enhance flavor. Stir in semi-sweet or dark chocolate chips once the peanut butter mixture is melted and well combined, then mix with the corn flakes as usual.
