Step 1

Combine the chocolate chips, milk, and marshmallows in a medium-size saucepan over medium heat. Stir frequently as the chocolate melts. Add the peanut butter and vanilla. Stir to melt and combine well.

Step 2

Remove from the heat. Lightly grease a 10-inch square pan or line with parchment. Pour the fudge into the pan and spread with a spatula. Chill in the refrigerator until firm. Slice into 1-inch pieces and store in an airtight container in the refrigerator. Enjoy!
