Grandma'S Heavenly Hash - cooking recipe

Ingredients

2 (7 ounce) bars milk chocolate bars (such as Hershey's(R))
1 (12 ounce) package semi-sweet chocolate chips
1 cup butter
1 cup chopped walnuts
1/2 (10.5 ounce) package miniature marshmallows
1 teaspoon vanilla extract

Preparation

Heat chocolate bars, chocolate chips, and butter in the top of a double boiler over simmering water, stirring frequently and scraping down the sides with a rubber spatula to avoid scorching.
Remove chocolate mixture from heat; stir in walnuts, marshmallows, and vanilla until completely coated. Spread mixture into 9x13-inch baking pan, gently pressing down with spatula to evenly flatten out. Refrigerate until hardened, 4 to 5 hours.
