In a large pot melt the 1 1/3 sticks of butter over medium heat.
Slowly incorporate the 1 bag of marshmallows until they are melted and add 1/2 teaspoon vanilla and 1/4 salt.
[OPTIONAL] Add food coloring until the marshmallow mixture is the color you desire. We used yellow, green, and purple for Mardi Gras.
Remove the pot from the heat and incorporate 6 cups of Rice Krispies stirring constantly.
Once marshmallow and cereal are thoroughly mixed move to a baking pan. [OPTIONAL] Line sheet with wax paper.
Repeat the steps above 2-3 times for each layer you plan to make. We did three.
Mixed softened cream cheese, softened butter, powdered sugar, vanilla, and salt until smooth and spreadable. Use the Kitchenaid.
Add cream cheese mixture between layers of rice krispies.
