Let's get sticky!
Pour the rice crispy cereal into a large heat proof bowl along with 2 cups of the mini marshmallows. Mix together.
In a large pot, brown the butter!
When the butter is browned remove from heat and mix in the remaining marshmallows, the marshmallow creme, the salt and vanilla. Fold together. The residual heat from the butter should start to melt the marshmallows. If nessesary return the marshmallow mixture to low heat and stir gently until the marshmallows have all melted and the mixture is smooth.
Pour the marshmallow goo into the cereal and mix together. A silicone spatula is my weapon of choice for this particular task. Don't use your bare hands, that will just lead to a frustrating situation in which a majority of the cereal will take up seemingly permanent residence between your fingers.
Quickly spread into prepared pan and press gently to even out.
Let cool, cut into bars, squares, triangles, or any manner of trapezoid/quadrangle you desire - what ever shape you choose prepare to revisit your childhood in a super sophisticated flashback!
