Frequently Asked Questions
How should I store Oreo Peanut Butter Fudge?
- Store the fudge in an airtight container in the refrigerator for up to one week. You can place parchment or wax paper between the layers to prevent the pieces from sticking together.
Can I make this fudge ahead of time?
- Absolutely! This is a great make-ahead dessert because it needs at least an hour to chill before slicing. You can easily prepare it a day or two before serving.
Can I use a different flavor of frosting?
- Yes. Vanilla frosting keeps the peanut butter flavor front and center, but chocolate frosting would be a delicious option if you want an even richer chocolate-peanut butter fudge.
