Save I am particularly partial to the smooth layer of peanut butter that goes beneath the chocolate when I was young my grandmother always let me spread it and I would swirl it in patterns now my own kids beg for that same job and it feels like passing down a little edible family tradition
Storage Tips
Store the sliced bars in an airtight container in the fridge for up to one week if you like a firmer bite keep them chilled but for fudgier bars let them sit at room temperature for about ten minutes before eating if you want to freeze them wrap the bars individually in parchment or wax paper then seal inside a zip top bag they will keep perfectly for up to three months simply thaw in the refrigerator overnight or at room temperature for thirty minutes
Ingredient Substitutions
