Expert Tips
- Full fat cream cheese creates the richest texture and helps the filling hold its shape.
- Regular creamy peanut butter works best for a smooth filling.
- The cream for the ganache should be very warm, not simmering or boiling.
- Let the chocolate chips sit in the cream for a few minutes before stirring to give it the richest, silkiest texture.
- 4 hours is the minimum chilling time for this pie, but overnight is even better.
Copycat Costco Peanut Butter Pie FAQs
Do you have questions about this recipe? Here are the answers to the most commonly asked questions.
This is an almost no-bake pie. Only the graham cracker crust needs to be baked. The rest is just chilled.
You can and should make this peanut butter pie ahead of time. Chilling overnight is ideal, so make it the day before you plan to serve it.
Refrigerate this pie for up to 4 days. You can also freeze it for longer storage.
Wrap an entire pie in a double layer of plastic wrap and a layer of foil and freeze for up to a month. You can also wrap individual slices in plastic wrap and freeze in an airtight, freezer-safe container.
You can, but it’s not recommended. Low-fat cream cheese won’t give you the same rich, creamy texture as full-fat cream cheese.
