Storage & Reheating

Frequently Asked Questions

Can I use a different type of cereal in this recipe?

Yes, you can use any type of cereal you prefer! Try using rice crispy cereal for a lighter texture or granola for added crunch and flavor. Just make sure the cereal you choose complements the sweetness of the marshmallows and peanut butter.

How do I prevent the mixture from sticking to the pan?

To prevent sticking, ensure you generously rub the pan with margarine before adding the mixture. You can also line the pan with parchment paper for easy removal. If the bars are still sticking, let them cool completely before cutting them into squares.

Can I make these bars vegan?

Absolutely! You can easily make these bars vegan by using a plant-based margarine and ensuring the marshmallows are vegan-friendly, as some brands contain gelatin. This way, you can enjoy a delicious, cruelty-free treat without compromising on flavor.
