Behold my Loaded Oreo Peanut Butter Bars, aka, the best bars I have ever made. Seriously, these peanut butter bars take the cake, so to speak, for the most outrageously delicious and downright addictive treat to ever come out of the Sweetest Menu Kitchen.
It’s a big call I know, but when you consider they have a chocolate Oreo crust, a smooth peanut butter filling and a layer of dark chocolate that is studded with peanut butter cups, chocolate chips, peanut butter chips AND honey roasted peanuts, it really is no surprise. No surprise at all.
We have already discussed the perfect match that is peanut butter and chocolate here, here and here. But I have to say it again because these bars take that perfect match and raise it like 1,000 times. They have everything. A crunchy chocolate biscuit base, thanks to the Oreos, a ridiculously smooth peanut butter filling and a chocolate topping that makes other chocolate toppings look, well, rather conservative.
I don’t want to be one of those people that goes on and on about one particular topic but I NEED to convince you guys to make these because I just can’t keep the secret to myself, i want to shout it from the rooftops! THESE BARS ARE AMAZING!
Oh and did I mention they are no bake?! Yes! No baking or cooking involved whatsoever. It just doesn’t get any better, I’m telling you. So what are you up to this weekend? I am attempting a few new recipe creations (did I hear someone say smores?) and getting ready to wish my mum a happy birthday.
I am also still coming to terms with the fact that it is August already – where is this year going? I can tell you one thing that will make your weekend even better – these Loaded Oreo Peanut Butter Bars! Go on, you know you want to! 😉

Description
Amazing peanut butter bar with an Oreo crust topped with chocolate and roasted peanuts.
Ingredients
Oreo layer
- 20 Oreo cookies
- 60 grams (1/4 cup) unsalted butter
Peanut butter layer
- 1 and 1/2 cup (375 grams) smooth peanut butter
- 115 grams (1/2 cup or 1 stick) unsalted butter, softened
- 190 grams (1 and 1/2 cup) icing or powdered sugar
- Pinch of salt
Chocolate layer
- 150 grams (1 cup) good quality dark chocolate, pieces
- 1 tablespoon smooth peanut butter
- 80 grams (1/2 cup) Reeses peanut butter cups, chopped
- 40 grams (1/3 cup) honey roasted peanuts
- A handful of chocolate chips
- A handful of peanut butter chips
Instructions
- Grease and line an 8 inch square tin with baking or parchment paper, ensuring two sides overhang. Crush your Oreos (filling and all) until they resemble fine crumbs using a food processor or if you don’t have one, use a plastic zip lock bag and a rolling pin. Melt your butter in the microwave, stirring in-between 10 second bursts and then pour over your Oreos. Stir until all the biscuit crumbs are nice and wet and then pour them into your prepared tin. Use the back of a spoon to gently push down the crumbs so they form a nice even layer – make sure you get into those corners! Pop into the fridge.
- Next, add your peanut butter, butter (make sure its nice and soft), powdered sugar and salt to a large mixing bowl. Beat together on low using an electric mixer until combined and then turn the speed up a little and whizz until your mixture becomes nice and smooth. Pour the peanut butter mixture over your Oreo crust and spread out as evenly as you can. Pop into the fridge.
- Finally, melt your milk chocolate in the microwave, stirring in between 15 second bursts. When the chocolate is almost melted, add the peanut butter and pop into the microwave for another 10-20 seconds until the chocolate is nice and smooth. Quickly pour the chocolate over your peanut butter layer and spread out until it fills all the gaps. Then its time to decorate! Cover the top while the chocolate is still wet with your chopped peanut butter cups, peanuts, chocolate chips and peanut butter chips. Pop into the fridge to set for 4 hours or overnight. Then cut into small squares and enjoy!

Hello,
I just altered your recipe and I am so satiated. I put oreo cool whip from savemart on top of the oreo layer. Then I used only 3/4 a cup of peanut butter to layer it. Next I used 8 snack size kitkats to layer the top. Delicious.(wifes request) Thank you for helping me make this scrumptious monster.

So glad to hear that Josh!
Can you tell me which is the size of this amazing bar?Regards from Serbia.
Hi Katarina! This bar is made in an 8 inch square tin and you can cut them into 12 squares. Hope that helps!
Have you ever made these with semi-sweet chocolate in place of the dark? I am making my list right now of what I need at the food store to make these later. I saw your recipe on Pinterest and I cannot WAIT to make these later! ☺
Hi Amy,
Semi-sweet chocolate would work fine! In fact, you could use any type of chocolate you like. I hope you love them – let me know how you go! 🙂
I just made these, and they’re just as amazing as they look! My friends loved them and demanded the recipe. I keep wandering back to the fridge in a half-conscious state to eat "just another half piece".
I used Ghirardelli 60% bittersweet dark chocolate for the top.
Hi Jordan! I’m so pleased that you made these and loved them! They are definitely one of my favourites. Also I’m glad I’m not the only one who found it hard to stop at one piece. Thanks for the great feedback!
What kind/brand of dark chocolate do you use? Chocolate chips? Dark chocolate candy bar?
Hi Joey! You can use any dark chocolate that is made for melting. Here in Australia we have melting chocolate in the baking aisle, I generally use the brand Cadbury.
Oh Jess!! Why oh why do you do this to me!!!??? Another gorgeous recipe!! Thanks for linking up with our Fabulous Foodie Fridays party! Have a great weekend xx
Hahaha aw thanks Lucy!
Oh my word! These look way too delicious… I really didn’t need to know about them!!
Sorry Sophie – the cat is out of the bag! 😉
