Peanut butter stuffed brownies are the perfect treat for anyone who loves the classic combo of chocolate and peanut butter. These decadent squares take a traditional fudgy brownie and give it a luscious twist, a hidden layer of smooth, salty-sweet peanut butter tucked inside. The result is an indulgent, gooey dessert that’s impossible to resist.
What makes these brownies truly special is the contrast in textures and flavors. The brownie layer is thick, rich, and loaded with deep chocolate flavor. It has that perfect crinkle top and a dense, chewy bite that every good brownie should have. But just beneath the surface, a surprise awaits, a creamy peanut butter filling that melts into the batter as it bakes, creating pockets of nutty goodness in every bite.
These brownies are a crowd-pleaser at parties, bake sales, or casual get-togethers. They’re also a great choice for gifting, especially when you want to treat someone to something homemade and memorable. You don’t need fancy ingredients or complicated steps, either. Most of what you need is probably already in your pantry: cocoa powder, flour, butter, eggs, sugar, and, of course, peanut butter.
The key to a perfect peanut butter stuffed brownie is in the layering. Half the batter goes in the pan first, followed by dollops of peanut butter, either straight from the jar or whipped up with a bit of powdered sugar for a thicker texture. Then the rest of the brownie batter is spread on top before baking. The peanut butter melts slightly during baking but stays distinct enough to offer that creamy center.
Once cooled and sliced, the visual payoff is just as satisfying as the taste, a rich brownie with a golden peanut butter ribbon running through the middle. These brownies store well and are even better the next day, making them an ideal make-ahead treat. Whether you’re a chocolate lover, a peanut butter fan, or both, this dessert is a must-bake.

Yummy! But is it really 25-30 min? Mine took way longer, maybe my oven is broken?✨
So good! But does it matter if I use crunchy peanut butter instead of creamy? Asking for a friend lol.
Delicious! But I added a bit of chocolate chips to the batter, and it made them even better!
I tried making these, but they turned out kinda dry. I followed the recipe exactly! What did I do wrong?
I dunno, man. This recipe looks too simple. Can something so easy taste that good? I’ll stick to my grandma’s recipe.
I don’t even like peanut butter, but these brownies were still good. Weird, right?
These brownies are amazing! The peanut butter filling is to die for! I can’t stop eating them!
1/2 cup of peanut butter isn’t enough! Should be more!
Why do you need to sift the flour? Seems unnecessary to me.
Delicious! I added some walnuts for crunch. Yummy!
My kids loved them! I just used almond butter instead.
I dunno, almond butter? Isn’t peanut butter kinda the whole point? 🤔
Almond butter sounds great! Glad your kids liked them. Gonna try it too!
Just made these! Very easy to follow. 👌
Keep it simple, don’t overthink it! Love this recipe!
I thought brownies were supposed to be chewy. These came out cakey.
Not impressed… tasted too sweet for my liking.
Tasted fine to me, but I guess it’s all about preference. Don’t give up on sweets yet!
I thought they were delicious! Maybe try less sugar next time?
These are my new favorite brownies! Sooo good! 😍
I found the batter too thick, anyone else? 🤔
