Notes

  • We made this to taste just like the pie sold at Costco. The only complaint that we have seen from others about the Costco pie is that the peanut butter layer is too sweet. You can reduce the powdered sugar in the peanut butter layer by 1/4 cup to make it less sweet or keep it as it is to taste like the actual Costco version. We wanted to keep it as true to the original as possible so we kept the peanut butter layer on the sweet side (which we still LOVE, it really just comes down to personal preference.)
