Notes

CHOCOLATE DIPPED PEANUT BUTTER SQUARES
To take them up a notch, dip the squares in melted chocolate chips or Ghirardelli chocolate melts. Let excess drip off (I find that dragging it across the edge of the bowl helps), then place on a parchment-lined baking sheet to set.
HOW TO STORE BARS
You can store the bars at room temperature, in the refrigerator, or in the freezer. We like them chilled, but they are delicious no matter how you store them. If stored in an airtight container, they will stay fresh for up to 7 days.
