Combine chocolate & nuts in slow cooker.

Cook on low for 1 hour, or until chocolate melts.

Please don’t lift the lid & keep a close eye on the chocolate to be sure to not overcook

After 1 hour, stir the mixture & fold in marshmallows

Transfer mixture into a parchment lined casserole dish or large jelly roll pan (I use a large 3/4 sheet jelly roll pan)

Place in refrigerator to harden completely

(if you are impatient like me, you can pop it in the freezer for about 20 minutes

Once set- remove by pulling up on the parchment paper & cutting into squares before transferring to an airtight container.
