Creating Peanut Butter Cheerio Bars is a breeze if you follow these simple steps:

1. Prepare the Pan: Line a 9×9-inch square pan with parchment paper, allowing some overhang for easy removal later.
2. Mix Wet Ingredients: In a medium saucepan, combine the peanut butter, honey or maple syrup, vanilla extract, and salt. Stir over low heat until the mixture is smooth and well-combined.
3. Combine with Cheerios: Remove the saucepan from heat and add the Cheerios to the peanut butter mixture. Stir until all the Cheerios are fully coated.
4. Add Optional Ingredients: If using optional add-ins like chocolate chips or dried fruits, fold them into the mixture at this point.
5. Transfer to the Pan: Pour the mixture into the prepared pan and press it down firmly with a spatula or your hands to ensure an even layer.
6. Chill the Bars: Place the pan in the refrigerator for about 30 minutes to allow the bars to set.
7. Cut Into Squares: Once chilled and firm, lift the bars out of the pan using the parchment overhang and cut them into squares or rectangles.
8. Store Properly: Store any leftovers in an airtight container at room temperature for up to a week or in the refrigerator for longer freshness.

These straightforward instructions will guide you to create Peanut Butter Cheerio Bars filled with amazing flavors.
