How to make Crispy Marshmallow Bars
To begin, gather all your ingredients. Preparing these bars is straightforward: the first step is to line your baking tin with nonstick paper to prevent sticking. Once that’s done, you’ll melt the butter and marshmallows together in a saucepan, stirring continuously to ensure a smooth mixture. It’s crucial to keep the heat at a medium level to avoid burning the marshmallows while they melt.
Once melted, remove the pan from the heat source and promptly fold in the puffed rice cereal. This step is important as you want to ensure every piece of cereal is coated evenly with the gooey marshmallow mixture. The final stage is to transfer the mixture into your prepared baking tin, ensuring it’s pressed down firmly for compact bars. Allow the mixture to chill in the refrigerator for a couple of hours, which helps it set properly, making sure each cut results in perfectly shaped bars.

Tips to make Crispy Marshmallow Bars
For the best results when making Crispy Marshmallow Bars, consider using fresh mini marshmallows. Stale marshmallows can lead to a less satisfying texture and flavor. When melting the butter and marshmallows, ensure you stir continuously to prevent any scorching at the bottom of the pan, as burned flavors can ruin the final product.
If you find that the mixture is too sticky when trying to press it into the tin, using a wet spatula or glass will aid in evenly distributing the mixture without it clinging. Finally, feel free to customize your bars by incorporating favorite sweets, like M&M’s or crushed cookies, into the mixture before pressing it into the tin.
Variation
No major variations, but you can adjust seasonings to taste.
