1 14 ounce can Sweetened Condensed Milk
1 12 oz package chocolate chips (I used Nestle Swirled White and Semi Sweet Chocolate Chips)
2 Tbs Butter
6 Marshmallows cut into very small pieces
2 c. Walnuts (optional)

In a saucepan, combine all ingredients and stir over low-medium heat until all chips are melted and mixture is smooth. Continually stir to avoid burning. Remove from heat and add marshmallows and walnuts (if desired). Spread all ingredients into greased 8x8 baking pan. Refrigerate until firm. Enjoy
