Ingredients

  • 1 cup sugar
  • 1 cup white syrup
  • 1/2 cup butter
  • 1 1/2 cups peanut butter
  • 6 cups Post Toasties

Instructions

  1. Combine sugar and white syrup in a saucepan and bring to a rolling boil.
  2. Remove from heat.
  3. Add butter and peanut butter to the mixture, stirring until smooth.
  4. Mix in the Post Toasties until evenly coated.
  5. Pour or drop the mixture into a 9 x 13-inch pan or drop by spoonfuls onto a prepared surface.

Tips & Substitutions

To enhance the flavor, consider using crunchy peanut butter for added texture, or try almond butter as a substitute. For a chocolate twist, you can sprinkle mini chocolate chips into the mixture before cooling. Make sure to stir quickly after adding the butter and peanut butter to avoid a grainy texture. If you prefer a less sweet option, reduce the sugar by 1/4 cup.

Serving Suggestions

These Post Toasties Bars make a delightful snack on their own, but they also pair well with a glass of cold milk or a warm cup of coffee. For a fun twist, serve them alongside a scoop of vanilla ice cream for dessert. They are perfect for parties or as a sweet treat in lunchboxes, similar to M&M Rice Krispie Treats.

Storage & Reheating

Store any leftover Post Toasties Bars 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, simply microwave for a few seconds until slightly warm, but enjoy them best at room temperature for optimal texture.

Frequently Asked Questions

Can I use a different type of cereal?

Yes, you can substitute Post Toasties with other cereals like Rice Krispies or Cornflakes. However, keep in mind that the texture and flavor may vary slightly. If you choose a sweeter cereal, consider reducing the sugar in the recipe to balance the sweetness.

How should I cut the bars for serving?

To cut the bars neatly, wait until they are completely cooled and firm. Use a sharp knife to slice them into squares or rectangles. For easier cutting, you can line the pan with parchment paper, leaving an overhang for easy removal before cutting.

Can I add mix-ins to the bars?

Absolutely! Feel free to add mix-ins such as nuts, dried fruit, or chocolate chips to the mixture before pouring it into the pan. Just make sure to adjust the consistency if necessary; additional ingredients may require a bit more binding or cooking time.
