Peanut butter lovers: this Old-Fashioned Peanut Butter Oreo Pie is one of the BEST desserts you’ll ever have! With a thick, no-bake Oreo crust, creamy peanut-butter filling & chocolate ganache drizzle, this pie will always be a favorite!

There’s nothing better than a thick slice of Old-Fashioned Peanut Butter Oreo Pie, served with a dollop of Homemade Whipped Cream or maybe even some No-Churn Cookies & Cream Ice Cream. Skip dinner…on to PB PIE!

Ingredients

  • Oreos – finely crushed Oreos make the perfect crust.
  • Unsalted butter – butter is added to the crust, the filling, and the ganache. It helps the Oreo crumbs bind together, it creates a creamy and decadent filling, and it gives the ganache a beautiful shine! Butter makes everything better!
  • Creamy peanut butter – we’re making a peanut butter pie, right?
  • Powdered sugar – powdered sugar lightens up your PB filling.
  • Vanilla extract – vanilla extract adds a touch of extra flavor to your filling. I love vanilla extract!
  • Semisweet chocolate chips – semisweet chocolate is just the right amount of darkness to create a chocolaty drizzle without being too bitter for the rest of the pie.
  • Heavy cream – heavy cream is the base for a luxurious ganache.
  • Salt – salt adds a touch of extra flavor.

Peanut Butter Pie Variations & Toppings

  1. Pre-made Oreo crust – you can sometimes find a pre-made Oreo crust in the baking aisle of your grocery store. It’s not going to be quite as thick and delicious as a homemade Oreo crust, but it will do the job if you’re in a pinch!
  2. Graham cracker crust – If you’re not an Oreo fan (which makes me cry a little!), you can use a graham cracker crust, either store-bought or made from scratch by mixing about 1 ½ cups graham cracker crumbs with ¼ cup sugar and 6 tablespoons melted butter.
  3. Golden Oreo crust – use golden Oreos instead of regular Oreos.
  4. No chocolate ganache – just want the peanut butter filling in a delicious Oreo crust? No ganache drizzle necessary!
  5. Finish with crushed Reese’s or peanut butter chips on the top.
  6. Add a strawberry or raspberry jam drizzle – use a Ziploc bag to pipe and drizzle your jam of choice…for a peanut butter and jelly pie!
