How to Make Peanut Butter Oreo Bars
Step 1: Prepare the Pan
Start by lining an 8×8 inch (20×20 cm) pan with parchment paper or aluminum foil. Leave an overhang around the sides. This makes it super easy to lift the bars out once they’re set!
Step 2: Make the Crust
In a bowl, crush those Oreo cookies into fine crumbs. Mix them with melted butter until they resemble wet sand. Press this mixture firmly into the bottom of your prepared pan. This crust is crucial as it provides a tasty base that holds everything together!
Step 3: Mix the Filling
In another bowl, beat together softened butter and brown sugar until smooth. Then add in your smooth peanut butter and sifted powdered sugar. Mix until well combined—the filling should be creamy and thick enough to spread easily over your crust.
Step 4: Spread It Out
Spoon the peanut butter mixture over your crust and spread it evenly with a spatula. Make sure it’s nice and flat so every bite is perfectly balanced with that delicious crust!
Step 5: Prepare the Chocolate Topping
Melt semi-sweet chocolate along with shortening in a microwave-safe bowl in short bursts, stirring frequently. Once melted and smooth, pour it over your peanut butter layer. This glossy topping adds a decadent finish!
Step 6: Chill
Cover your pan and refrigerate for at least an hour until firm. This step is key—it allows all those wonderful flavors to meld together beautifully.
Step 7: Slice & Serve
Once set, use the parchment overhang to lift your bars out of the pan. Cut them into squares and enjoy! These Peanut Butter Oreo Bars are perfect for sharing—or keeping all to yourself!
Pro Tips for Making Peanut Butter Oreo Bars
Making these Peanut Butter Oreo Bars is a delightful experience, and with a few simple tips, you can ensure they’re absolutely perfect!
-
Use room temperature ingredients: Bringing your butter and peanut butter to room temperature before mixing helps create a smoother filling that blends seamlessly with the powdered sugar.
-
Crush Oreos finely: The finer your crushed Oreos, the more cohesive your crust will be. This ensures a solid base that holds up beautifully when you cut the bars.
-
Chill thoroughly: Allowing the bars to chill in the fridge for at least an hour after assembly is crucial. This helps them set properly, making slicing easier and enhancing their overall texture.
-
Experiment with chocolate types: Feel free to mix different types of chocolate! Dark chocolate or white chocolate can add unique flavors and visual appeal to your bars.
-
Customize with add-ins: Consider folding in some chopped nuts or mini chocolate chips into the peanut butter filling for extra texture and flavor variations.
How to Serve Peanut Butter Oreo Bars
These Peanut Butter Oreo Bars are not just delicious; they also look fabulous on any dessert table! Here are some creative ways to serve them.
Garnishes
- Drizzle of chocolate: A light drizzle of melted chocolate over the top adds an elegant touch and enhances the chocolaty flavor.
- Chopped peanuts: Sprinkling chopped peanuts on top provides a nice crunch and complements the peanut butter beautifully.
- Whipped coconut cream: A dollop of whipped coconut cream can bring a creamy contrast that balances out the richness of the bars.
Side Dishes
- Fresh fruit salad: A refreshing fruit salad made with seasonal fruits can brighten up your dessert table and provide a light contrast to the rich bars.
- Vanilla almond milk: Serve these bars alongside a glass of vanilla almond milk for a deliciously nutty pairing that complements the flavors perfectly.
