11 1/2 oz. semi-sweet choc chips
11 1/2 oz. milk choc chips
1/2 c. creamy peanut butter
Line an 8 inch baking dish with parchment paper.
Spread 1 cup mini marshmallows onto the bottom of the prepared baking dish.
In a large bowl, combine the chocolate chips and peanut butter. Make sure the bowl is microwave safe. Microwave for 30 seconds, stir with a spatula. Continue cooking the fudge in 30 second increments, stirring in between, until the mixture is smooth.
Stir in the remaining marshmallows and peanut butter cups.
Pour the chocolate mixture into the prepared baking dish. Use a spatula to spread it out evenly.
Chill in the refrigerator until firm; at least 2 hours. Cut into squares.
