Unbelievable Peanut Butter Pie - Sally's Baking Addiction (2024)

Peanut butter pie is rich and decadent, combining creamy peanut butter and sweet chocolate in each bite. This over the top dessert features a peanut butter Oreo cookie crust, peanut butter filling, Reese’s Pieces, and homemade chocolate ganache. It’s unbelievable!

There’s no flavor duo quite like peanut butter + chocolate. We’ve made chocolate peanut butter cheesecake bars, no-bake peanut butter bars, chocolate peanut butter snack bars, and peanut butter ice cream pie to name a few. My chocolate chip cookie layer cake is even filled with a chocolate peanut butter frosting! Today, we’re adding another recipe to the chocolate peanut butter mix: truly unbelievable peanut butter pie.

There’s a lot to cover, so let’s dive right in.

Today’s recipe is a new twist on classic peanut butter pie with a crunchy peanut butter Oreo cookie crust, colorful Reese’s Pieces candies, creamy peanut butter filling, and smooth chocolate ganache. It’s a peanut butter lover’s dream come true.

Here’s why you’ll love it:

• Totally indulgent
• Quick and easy to prepare
• Made with only 10 ingredients
• Tons of texture in each bite
• Perfect for birthdays and celebrations
• A great make-ahead recipe

4 Parts to Peanut Butter Pie

1. Peanut Butter Oreo Crust
2. Peanut Butter Filling
3. Chocolate Ganache
4. Reese’s Pieces

Though the written recipe is below, let me walk you through each part so you understand exactly what you’re doing.

Peanut Butter Oreo Crust

It wouldn’t be peanut butter pie without an Oreo crust, but let’s use peanut butter Oreos! Regular Oreos work just as well, but peanut butter Oreos add another layer of peanut butter flavor. We’re using the same recipe and technique found over on my Oreo Crust Recipe page. Pulse the Oreos (the whole Oreo including the chocolate cookies and the filling) into a fine crumb, then combine the Oreo crumbs with a little melted butter. Just 2 ingredients and so easy.

Press the mixture firmly into a pie dish and bake the crust. I recommend beginning with this step so the crust has time to cool down before assembling. This is the only layer that requires baking—the rest of the recipe is completely no-bake! I love making this pie in the warmer summer months when our kitchen welcomes a break from the hot oven.

You could use a regularOreo cookie crustor even aBiscoff pie crustinstead if you’d like.

Peanut Butter Pie Filling

This peanut butter filling is about as decadently rich as we can get. It’s made with just 5 ingredients including heavy cream, peanut butter, cream cheese, confectioners’ sugar, and vanilla extract. You can’t really taste the cream cheese; rather, you truly just taste peanut butter. We use the exact filling as a layer in peanut butter banana cream pie also. It has as much peanut butter flavor as these peanut butter balls and these super soft peanut butter cookies.

You’ll begin by whipping the heavy cream into whipped cream. In a separate bowl, mix the other 4 ingredients together, then gently fold the whipped cream into the peanut butter mixture. The result is a creamy, airy peanut butter filling.

Chocolate Ganache Topping

You only need 2 ingredients for the chocolate ganache topping: chocolate and heavy cream. You’ll simply pour warm cream over chocolate and stir. Use a quality chocolate because it’s where all of the flavor comes from. I would avoid using chocolate chips, which contain a stabilizer—use the real deal. Pure chocolate never lets you down. Never! See my chocolate ganache page if you need extra help with it.

You’ll want to make the ganache before the peanut butter layer because it must fully cool down prior to pouring over the peanut butter filling. This time also allows the ganache to thicken, creating a fudge-like consistency when the pie is ready to serve.

Crushed Reese’s Pieces

You’ll find crushed Reese’s Pieces in two places—on top of the Oreo crust and sprinkled on top of the chocolate ganache. They add a little crunch, a little color, and that little something extra! Instead of Reese’s Pieces, try crushed M&Ms, or skip them altogether.

Like peanut butter cup tart, the only baking we’ll do is for the crust. Other than that, the refrigerator does all the work. The pie must set up in the refrigerator for 5–6 hours. Overnight would be wonderful, but I’ve made this peanut butter pie twice with just 5 hours of chill time. Peanut butter perfection each time. This dessert is always fun for birthdays, but I’ve served it along side Father’s Day recipes, Mother’s Day recipes, Valentine’s Day, anniversaries, a random Sunday (why not?), you name it. It’s always devoured!
