Step 1

Have ready a greased 9x13" casserole dish.

Step 2

Add the butter to a large pot over medium heat and melt. As soon as the butter has melted, add 8 cups miniature marshmallows and stir until melted and combined. Turn off the heat and stir in the vanilla and salt.

Step 3

Add the Cocoa Krispies to the pot and stir to combine, then stir in the remaining 2 1/2 cups of marshmallows, the chocolate chips, and stir to evenly distribute.

Step 4

Transfer the contents of the pot to the prepared casserole dish, and with greased hands, gently press down to smooth over the top. Do not press hard or the marshmallow treats will be tough.

Step 5

Allow to set, about 30-45 minutes. Cut into 12-16 squares, serve, and enjoy!
