Ingredients

  • 1 cup light corn syrup
  • 1 cup white sugar
  • 2 cups peanut butter
  • 7 cups dry cereal

Instructions

  1. Melt together the corn syrup and white sugar in a saucepan over low heat.
  2. Remove from heat and stir in the peanut butter until the mixture is smooth.
  3. Add the dry cereal to the mixture and stir until well coated.
  4. Press the mixture into a 13 x 9-inch pan evenly.
  5. Allow to cool, then cut into squares.

Tips & Substitutions

For a smoother mixture, ensure the corn syrup and sugar are fully melted before adding the peanut butter. If you prefer a crunchier texture, consider using a mix of cereals, such as Rice Krispies or Cheerios. You can also substitute honey for light corn syrup for a more natural sweetener. Just keep in mind that the flavor will slightly change.

Serving Suggestions

These peanut butter bar cookies are great on their own, but they also pair beautifully with a glass of cold milk or a warm cup of coffee. For a fun twist, serve them alongside a slice of Pie or as a sweet treat during a movie night. They make a perfect snack for kids and adults alike.

Storage & Reheating

Store the peanut butter bar cookies in an airtight container at room temperature for up to a week. For longer storage, you can refrigerate them for up to two weeks. To reheat, microwave each square for about 10-15 seconds to soften without melting. This keeps the bars chewy and delicious.

Frequently Asked Questions

Can I use natural peanut butter for this recipe?

Yes, you can use natural peanut butter, but make sure it has a similar consistency to regular peanut butter. Natural varieties may have more oil, so you may need to stir it well before measuring. This will ensure that the bars hold together properly.

What can I add to these bars for extra flavor?

You can enhance the flavor by adding chocolate chips, dried fruits, or even nuts to the mixture. For a more indulgent treat, consider drizzling melted chocolate on top once the bars have cooled. This adds a delightful layer of richness.

Can I make these bars gluten-free?

Absolutely! Simply choose gluten-free cereals, such as rice or corn-based options, to ensure the bars are safe for those with gluten sensitivities. Always check the labels of your ingredients to confirm they are gluten-free.
