Notes
*Make sure you use salted butter over margarine. Butter will give your marshmallow treats a richer flavor and texture.*You can use pretty much any crisp rice cereal, whether you choose to use the original Rice Krispies cereal, a generic brand, or a store brand.*You can use big or mini marshmallows, but I highly recommend mini marshmallows, since they'll be a lot quicker and easier to melt.HOW TO STORE RICE KRISPIE TREATSIt's important to store your treats in an airtight container or sealed plastic bag. And like I mentioned above, you'll probably want to eat them within the first 2 or 3 days.CAN YOU FREEZE RICE KRISPIE TREATS?You can if you need to. And then get them out with at least half an hour to thaw before serving.Be sure when freezing them, though, that you again store them in an airtight container or freezer bag. And you might even put wax paper or parchment paper between the layers of treats so they don't stick together.HOW TO KEEP RICE KRISPIE TREATS SOFTSoft Rice Krispie treats are one of those desserts that after 2 or 3 days will start to harden up and be either extra chewy or rock solid.Two ways to ensure that you have the softest treats possible is by using fresh ingredients, namely marshmallows and cereal, and by cooking the marshmallow mixture on low to medium heat.Also, use lots of marshmallows. If you're using 6 cups of cereal (as in the case with this recipe), you'll want the same amount of marshmallows, so a 1:1 ratio.
