The generously sized half sheet pan ensures there’s more than enough to go around, satisfying every sweet tooth and making sure everyone gets a piece (or two!).
The Irresistible Allure of Cookies and Cream Blondies
Our journey into the wonderful world of blondies has been an exciting culinary adventure, constantly exploring new flavor combinations and textures. The idea for these delightful Oreo cookie blondies has been brewing for quite some time, and it felt like the perfect moment to bring them to life. One of the primary reasons we adore making blondies is their incredible adaptability; they serve as a versatile canvas for countless creative variations. From vibrant sprinkles to decadent chocolate chips and even various candy bar mix-ins, the possibilities truly feel endless.
We first fell in love with blondies a couple of years ago when we perfected our Lotsa Candy Bar Blondies, a recipe that quickly became a fan favorite for its indulgent and rich profile. Following that success, we ventured into festive seasonal baking with our fun Easter Egg Blondies, which were met with equally enthusiastic reviews from family and friends. The overwhelmingly positive reception to these creative twists encouraged us to experiment further, leading to the playful creation of Animal Cracker Blondies. With such a history of successful and imaginative variations, we are always eager to develop more exciting flavors and recipes. However, for this particular batch, we decided to return to a beloved, timeless classic that everyone adores: cookies and cream.
What is it about the cookies and cream combination that makes it so universally popular and utterly captivating? Perhaps it’s the magical synergy of rich, dark chocolatey cookies with their sweet, creamy filling that creates an unparalleled textural and flavor experience. It’s a taste that evokes comfort, nostalgia, and pure, unadulterated joy. Let’s be honest, the primary reason for its enduring popularity is simply that it tastes absolutely phenomenal! My colleagues are avid fans of anything cookies and cream, so I had a strong, confident feeling these blondies would be an undeniable winner long before they even made it into the oven. The sheer anticipation and excitement from everyone were enough to tell me these would be a smashing success, disappearing faster than I could cut them!


Expert Tips for Baking Your Best Oreo Blondies
Don’t Waste a Crumb!
When you take on the satisfying task of breaking or chopping those delightful Oreos, some delicious crumbs are absolutely inevitable. But here’s a golden rule: don’t let a single one go to waste! These tiny bits of chocolatey goodness are flavor powerhouses. Feel free to stir them directly into the blondie batter along with the larger cookie pieces. Alternatively, for an extra visual appeal and delightful textural surprise, sprinkle those tempting crumbs generously over the top of the batter just before it goes into the oven. Every crumb adds to the magic!
Achieve Even Baking for the Ultimate Texture
To ensure your blondies bake evenly and achieve that coveted perfect chewy-on-the-inside, slightly crispy-on-the-edges texture, it’s absolutely crucial to spread the batter uniformly in your prepared sheet pan. Take a moment to gently and patiently spread it from edge to edge, making sure the thickness is consistent across the entire surface. This seemingly small step makes a monumental difference in the final product, preventing dry edges or undercooked centers.
The Power of Quality Ingredients
While blondies are wonderfully forgiving, using quality ingredients can truly elevate your baking results from good to absolutely spectacular. Opt for fresh eggs, a good quality vanilla extract, and always make sure your brown sugar is soft and packed. The molasses content in brown sugar is not just for flavor; it’s key to the blondies’ characteristic chewiness and deep, caramel-like notes. Fresh ingredients ensure the most vibrant flavors and the best possible texture.
Cooling is Crucial!
Patience is a virtue, especially when it comes to blondies. It might be tempting to dive right into the warm, gooey goodness, but allowing your blondies to cool completely in the pan on a wire rack is essential. This cooling time allows them to set properly, ensuring clean, perfect squares when you cut them, and helps develop that ideal chewy texture. Rushing this step can result in crumbly, messy blondies!

Equipment
-
OXO Mixing Bowl Set
-
Nordic Ware Half Sheet Pans and Cover
Ingredients
- 2½ cups all purpose flour
- 2½ teaspoons baking powder
- 1 teaspoon salt
- 1 cup vegetable oil
- 2¼ cups light brown sugar packed
- 4 large eggs
- 1 teaspoon vanilla extract
- 20 Oreo cookies roughly chopped
Instructions
-
Preheat your oven to 350°F (175°C). Prepare a 13x18x1 inch pan (a standard half sheet jelly roll pan) by lightly greasing it and dusting with flour, or spraying generously with a non-stick cooking spray. This crucial step ensures your baked blondies will release easily from the pan after cooling.
-
In a medium-sized mixing bowl, combine the dry ingredients: all-purpose flour, baking powder, and salt. Use a whisk to thoroughly blend them together, ensuring an even distribution throughout the mixture. This step prevents pockets of leavening agents or salt in the finished blondies. Set this bowl aside for later use.
-
In a separate large mixing bowl, combine the light brown sugar and vegetable oil. Stir them together vigorously until they are well blended and the mixture appears smooth and consistent. This forms the rich, moist base of your blondies. Next, beat in the large eggs one at a time, ensuring each egg is fully incorporated into the sugar-oil mixture before adding the next. Finally, stir in the vanilla extract until just combined, being careful not to overmix.
-
Gradually add the whisked dry ingredients to the wet ingredients in the large bowl. Stir until just combined. The key here is to mix until no dry streaks of flour remain, but avoid overmixing the batter, as this can develop the gluten too much and result in tough blondies. A few small lumps are perfectly fine and often preferable to an overmixed batter.
-
Gently fold in about two-thirds of your roughly chopped Oreo cookies into the blondie batter. Spread the prepared batter evenly into your greased and floured sheet pan using a spatula, ensuring it covers the entire surface from edge to edge with a consistent thickness. Finally, sprinkle the remaining one-third of the chopped Oreo pieces generously over the top of the batter.
-
Bake the blondies in the preheated oven for 28-32 minutes. You’ll know they are ready when the edges appear beautifully golden brown, and the middle looks set and firm when gently pressed. A toothpick inserted into the center should come out with moist crumbs clinging to it, not wet batter. Avoid overbaking to maintain their signature chewy texture.
-
Once baked, remove the pan from the oven and allow the blondies to cool completely in the pan on a wire rack. This patience is absolutely critical for them to set properly, ensuring you can cut them into neat, clean squares. Once thoroughly cooled, cut them into your desired portion sizes. Store cooled blondies in an airtight container at room temperature for up to a week, or freeze them for up to three months for a convenient future treat.
