Hershey Almond: We love changing up this classic and using Hershey milk chocolate bars with almonds. Melt them just like you would the other bars and following the directions.How many Hershey Bars? Use 5 (1.45 oz) bars with almond or 5 (1 oz) bars regular milk chocolate bars. Try another crust: Some readers have said they used a cookie crust.Garnish: I used an extra bar to use as garnish.
