Thoughts on the Recipe

I wasn’t totally sure this one would work—but wow, I’m so glad I tried it! A brownie baked into a pie sounds wild, but it’s out of this world. You get a buttery, cookie-like crust wrapped around a gooey, chocolatey brownie center. And when you throw in peanut butter and chocolate together? It’s basically dessert perfection.

Texture Tips

The key to getting the perfect slice is simple. Just follow the baking instructions on your brownie mix box! It bakes exactly like regular brownies, even though it’s in a pie crust. Once it’s cooled and sliced, the texture is spot on—fudgy, rich, and just the right amount of soft in the center.

Make It Your Own

One of the best parts is how customizable this pie is. Drizzle it, sprinkle it, load it up with your favorite candy—it’s totally up to you. You can also theme it for the holidays. Top it with chocolate peanut butter bunnies for Easter, spooky candy for Halloween, or chopped red and green chocolates for Christmas. It’s a simple way to make it fit any occasion!

FAQ

Q: Can I use regular Oreos instead of Peanut Butter Oreos?

A: You can, but the peanut butter flavor won’t be as bold. Add 1–2 tablespoons of peanut butter to the crust mixture to make up for it.

Q: Do I need to chill the pie?

A: It’s optional, but chilling it for 2–3 hours gives the center an extra fudgy texture that’s totally worth the wait.

Q: Can I make this ahead of time?

A: Yes! This pie stores well in the fridge for up to 4 days—just cover it tightly.

Q: Can I use homemade brownie batter?

A: Definitely! Just make sure it’s the right amount for an 8×8 pan so it doesn’t overflow the crust.

Sprinkle of Fun

This Peanut Butter Brownie Pie was made for sharing—and what better way to enjoy it than a fun night with your favorite people? Pack it up and bring it to a friend’s house for one of those easygoing hangouts. Throw on a feel-good movie or start a card game tournament (Uno is my personal favorite), and let dessert be part of the fun.

Want to take it up a notch? Bring extra toppings like whipped cream, chopped peanut butter cups, or warm chocolate sauce, and let everyone customize their own slice. It’s low-effort, high-reward fun—and guaranteed to get more than a few “Wait, you made this?!” reactions.

Ingredients

Scale 1x2x3x

• 2 cups crushed Peanut Butter Oreos (about 22 cookies)
• 6 tbsp butter, melted
• 2 tbsp sugar
• 1 box brownie mix (for an 8x8 pan) + ingredients listed on the box
• 1/3 cup peanut butter chips
• 1/4 cup Butterfinger bits (or substitute with an additional 1/2 cup peanut butter chips)
• Melted milk chocolate, for drizzling
• Melted peanut butter chips, for drizzling
• Mini chocolate chips, for garnish

Instructions

1. Preheat your oven to 350°F. Crush the Peanut Butter Oreos in a food processor until they become fine crumbs. In a bowl, mix the crumbs with melted butter and sugar until fully combined. Press the mixture into the bottom and sides of a 9-inch pie plate.
2. Bake for 8 minutes, then set aside to cool.
3. In a medium bowl, prepare the brownie mix according to the package instructions. Fold in the peanut butter chips and Butterfinger bits.
4. Pour the brownie batter into the cooled crust and bake for according to the package, or until the center is just set but still slightly soft for a fudgy texture.
5. Allow the pie to cool completely. Drizzle with melted milk chocolate and peanut butter chips, then sprinkle with mini chocolate chips or mini butterfinger pieces. 

Note:

This pie is delicious at room temperature, but chilling it in the fridge for 2–3 hours makes the center extra fudgy!
