Classic rice krispie squares that are perfectly soft and gooey and the most delicious nostalgic treat. These rice krispie treats will taste just like your childhood and are one of the easiest desserts to make!
Add rice krispies to a large mixing bowl and set aside. Grease or line a 9x13 pan with parchment paper and set aside.
In a large saucepan, add the butter and salt. Heat over medium low heat until melted. Add the marshmallows and stir often until melted and combined with the butter. DON'T overheat this mixture or your squares will be hard.
Remove from heat and stir in the vanilla extract. Pour the marshmallow mixture over the rice krispies and stir with a wooden spoon or spatula until they are all coated in the marshmallow mixture.
Dump the rice krispies into your prepared pan. With a little butter on your hands, gently press the mixture into the pan so it's even and flat. Don't push down hard or they will be very tough. Be careful as they will be hot, you can also use a greased spatula if they're too hot to touch.
Allow them to fully cool, slice into squares and serve. Store in an airtight container with additional marshmallows to keep them fresh!
