You will need 1 13x9 baking pan. Measure out your butter and place it in a microwavable safe container and microwave it until it melts (a minute should do fine).

Measure out your graham cracker crumbs into a bowl.

Take the butter out of the microwave and make sure it's completely melted. Mix butter and graham cracker crumbs together.

Mix together til the graham crackers are moist.

Spray your pan with some Pam or other food release spray of choice. Then pour the graham crackers in the pan.

Flatten the graham crackers evenly. I find that using a glass usually works best.

Add your marshmallows first to the pan.

Then your chocolate chips.

Then your sweetened condensed milk. Make sure you spread it evenly.

Preheat oven to 350F. Bake for 25 minutes or until bubbly.

This is how it should look out of the oven. Let it cool to about room temperature and then refrigerate for about an hour. Then cut and serve. They can be a bit messy but they are delicious. If desired, slice some banana up and place on top and microwave for 1 minute. Its pretty good. Hope you all enjoy it.
