Notes

Recipe Tips.
  • Use the back of a spatula or the bottom of a measuring cup to press the first oat layer evenly into the pan.
  • Keep the heat low. Stir the oats while they cook, and melt the chocolate and peanut butter gently to help prevent scorching.
  • Give the bars several hours in the refrigerator so the chocolate layer firms up and the bars are easier to cut. Use a sharp knife, wiping it clean between cuts.
  • For easy removal, leave parchment paper hanging over the sides so you can lift the slab out after chilling.
Store. Store the bars at room temperature in an airtight container for 3-5 days or in the fridge for up to a week. 
Freeze. Once the bars have set. Wrap the entire bar with plastic wrap and again with foil. If freezing individual pieces, wrap each with plastic (fold-top sandwich baggies also work for the individual sizes) and place them together in a freezer Ziploc. Thaw before eating.
