Decadent Oreo Blondies with a Triple Oreo Cookie Crust: The Ultimate Treat
As the whispers of summer fade into the brisk promise of autumn, many of us find ourselves clinging to the last vestiges of sunshine and carefree days. The rapid approach of holidays like Labor Day often brings a bittersweet realization: another vibrant summer is drawing to a close. While we might not be ready to swap our flip-flops for warm sweaters or dive headfirst into pumpkin spice everything just yet, there’s one surefire way to ease the transition and celebrate the joy of the season, whatever it may be: with an utterly divine dessert.
And what better way to do that than with a treat that perfectly bridges the gap between light summer indulgence and comforting fall richness? Introducing our stellar recipe for Oreo Blondies with an Oreo Cookie Crust – a dessert so easy to make and so incredibly delicious, it will have everyone asking for more. Forget your end-of-summer blues; these blondies are here to turn any moment into a celebration.

Why These Oreo Blondies Are a Game-Changer
Blondies have long been cherished as the lighter, chewier cousin to the classic brownie, offering a delightful vanilla and butterscotch-infused experience. But what happens when you elevate this beloved treat with the iconic flavor and texture of America’s favorite cookie? Pure magic! This recipe takes the concept of a blondie and transforms it into a multi-layered masterpiece that boasts not just one, but three irresistible Oreo elements, delivering an unparalleled depth of flavor and texture in every bite.
Imagine this: a rich, dark, and intensely chocolatey Oreo cookie crust forms the perfect foundation. Piled high on top is a thick, chewy, golden blondie layer, bursting with vanilla goodness. And just when you thought it couldn’t get any better, the entire creation is generously studded and topped with even more crunchy Oreo cookie pieces. This isn’t just a dessert; it’s an experience – a symphony of textures from the crisp crust to the soft blondie, all unified by that distinct, delightful Oreo taste.

My husband, Tom, perfectly summed it up after his first bite: “These are ridiculous!” And he’s not wrong. While blondies themselves are far from new, and many have experimented with adding Oreos, the combination of an Oreo crust, an Oreo-studded blondie, and an Oreo topping truly sets this recipe apart. It’s a triple threat of deliciousness that promises to satisfy even the most discerning sweet tooth.

Crafting Your Perfect Oreo Blondies: Tips for Success
Creating these heavenly homemade Oreo bars is surprisingly simple, making them an ideal project for bakers of all skill levels. To ensure your blondies turn out absolutely perfect, here are a few expert tips:
The Oreo Cookie Crust: The Foundation of Flavor
- Finely Ground Crumbs: For the best crust, ensure your Oreo cookies are processed into very fine crumbs. This helps them bind together beautifully with the melted butter and creates a firm, even base. A food processor is your best friend here.
- Press Firmly: After combining the crumbs with melted butter, press the mixture firmly and evenly into your prepared pan. This compact layer is crucial for a stable crust that won’t crumble when cut.
- Pre-Baking is Key: Don’t skip the brief pre-bake for the crust. This step sets the crust, making it sturdy enough to support the blondie batter and giving it a delightfully crisp texture.
The Blondie Batter: Chewy Perfection
- Creaming Butter and Sugar: The foundation of a good blondie is the creaming process. Beat the butter and brown sugar together until they are light and fluffy. This incorporates air, contributing to the blondies’ wonderfully chewy texture.
- Don’t Overmix: Once you add the dry ingredients to the wet, mix just until combined. Overmixing the flour can develop the gluten too much, leading to tough blondies rather than the desired tender chewiness.
- Evenly Spread: Carefully spread the blondie batter over the pre-baked Oreo crust, smoothing the top. This ensures an even bake and beautifully uniform bars.

Baking and Cooling: The Patience Pays Off
- The Right Pan: I personally love using a 9-inch cheesecake pan with a removable bottom for super easy removal of the blondies. However, a standard 9-inch baking pan will work just as well; simply line it with parchment paper, leaving an overhang on the sides for easy lifting.
- Watch for Doneness: The ideal bake time is usually between 35-40 minutes, but ovens vary. Start checking around 35 minutes. You’re looking for golden-brown edges and a toothpick inserted into the center that comes out with a few moist crumbs, not wet batter. Overbaking can lead to dry blondies, so err on the side of slightly underbaked for maximum chewiness.
- Patience is a Virtue (Especially for Cooling): This is perhaps the most crucial tip! Let your blondies cool for at least one to two hours, or even longer, before attempting to cut them. Rushing this step will result in messy, crumbly bars. Cooling allows them to set properly, giving you clean, beautiful squares or wedges.

Serving Suggestions and Variations
While these decadent blondies are utterly perfect on their own, a scoop of vanilla ice cream takes them to an even higher level of indulgence. The cold, creamy ice cream perfectly complements the warm, chewy blondie, creating a dessert experience that is truly unforgettable. You could also drizzle them with a bit of chocolate syrup or a light caramel sauce for an extra touch of decadence. For those who love a bit of crunch, consider adding some chopped nuts like pecans or walnuts to the blondie batter alongside the Oreo pieces, though the pure Oreo experience is hard to beat!

Perfect for Any Occasion
Whether you’re hosting a Labor Day barbecue, bringing a treat to a potluck, or simply craving something sweet for a quiet evening at home, these Oreo Blondies with Oreo Cookie Crust are the ideal choice. Their crowd-pleasing flavor and impressive appearance make them a fantastic addition to any dessert table. And because they’re so easy to make, you can whip up a batch whenever the craving strikes!
So, as summer gently gives way to the next beautiful season, let these amazing blondies be your sweet companion. They’re a reminder that deliciousness knows no season and that some treats are simply timeless. I can’t think of a better way to drown my end-of-summer sorrows – can you?

Ingredients
Oreo Cookie Crust
- 24 Oreo Cookies
- 5 Tbsp. unsalted butter, melted
Blondies
- 2 cups all-purpose flour
- 1 tsp. baking powder
- 1 tsp. sea salt
- 1 cup unsalted butter
- 2 cups light brown sugar, lightly packed
- 2 large eggs
- 3 tsp. vanilla extract
Topping
- 8-10 Oreo Cookies, broken into pieces
Instructions
Oreo Cookie Crust
- Preheat oven to 350 degrees F (175 C). Lightly spray the bottom and sides of a 9-inch cheesecake pan with nonstick cooking spray. Set aside.
- Place Oreo cookies in a food processor and pulse a few times until you have fine crumbs. Transfer crumbs to a medium bowl. Add the melted butter and mix with a fork until well combined.
- Press the cookie crumbs evenly into the bottom of your prepared pan. Bake the crust for 9-10 minutes. Remove from the oven and set aside.
Blondies
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In the bowl of a stand mixer fitted with a paddle attachment (or using a hand mixer), cream the butter and brown sugar on medium-high speed until light and fluffy. Reduce speed to low and add the eggs, one at a time, mixing until just combined after each addition. Add the vanilla extract and mix until incorporated. Slowly add the dry ingredients to the wet ingredients and mix just until combined. Be careful not to overmix.
- Spread the blondie mixture evenly on top of the pre-baked Oreo cookie crust, smoothing the top. Generously sprinkle the broken Oreo cookie pieces over the top. Bake for 35-40 minutes, or until the edges are lightly browned and a toothpick inserted into the middle comes out with only a few moist crumbs. Begin checking at 35 minutes to prevent overbaking.
- Allow the blondies to cool completely in the pan for at least one to two hours before cutting into wedges or squares. Serve with vanilla ice cream, if desired, for an extra treat.
