Ingredients You’ll Need
Gathering simple but essential ingredients is the first step to making these bars shine. Each ingredient plays a crucial role: the brownie mix gives the fudgy base, the Oreos add delightful crunch and creaminess, and the white chocolate chips bring creamy, mellow sweetness that perfectly balances the whole dessert.
- 1 box brownie mix: Provides a quick and delicious fudgy foundation without the fuss of mixing from scratch.
- 2 eggs, 1/2 cup vegetable oil, 1/4 cup water: Usually called for by the brownie mix, these bind and moisten the layers.
- 1/2 cup unsalted butter, melted: Brings richness and a tender crumb to the blondie layer.
- 3/4 cup packed brown sugar: Adds moisture and a deep caramel flavor to the blondie.
- 1/4 cup granulated sugar: Balances sweetness and contributes to texture.
- 2 large eggs: Essential for structure and chewiness in the blondie.
- 1 teaspoon vanilla extract: Elevates all the flavors and adds warmth.
- 1 1/2 cups all-purpose flour: Builds the blondie’s framework for perfect texture.
- 1/2 teaspoon baking soda: Helps the blondie rise just enough to be soft but firm.
- 1/2 teaspoon salt: Balances sweetness and enhances flavor depth.
- 1 cup white chocolate chips: Stirred into the blondie for pockets of creamy sweetness that melt in your mouth.
- 20 Oreo cookies: The star of this recipe, sandwiched right between the brownie and blondie layers for that signature taste and crunch.
How to Make Oreo Brownie Blondie Bars Recipe
Step 1: Prepare the Brownie Base
Start by preheating your oven to 350°F and lining a 9×13-inch baking pan with parchment paper, then lightly grease the paper to ensure easy removal. Prepare the brownie batter according to the package directions, combining eggs, oil, and water as instructed. Spread this smooth, fudgy batter evenly in the bottom of your prepared pan. This will soon become the luscious base for your Oreo Brownie Blondie Bars Recipe.
Step 2: Layer the Oreo Cookies
Next, gently place the Oreo cookies in a single layer right over the brownie batter. This layer not only adds a delightful crunch but also delivers the familiar cookies-and-cream flavor that perfectly complements both the rich brownie and sweet blondie layers. Take your time here to arrange them neatly; every bite should have an Oreo surprise.
Step 3: Mix the Blondie Batter
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until nice and smooth. Then add in the eggs and vanilla extract, mixing until everything is combined and glossy. Stir in the flour, baking soda, and salt just until they disappear into the batter. Finally, fold in the white chocolate chips for those pockets of sweet joy. This batter will sit beautifully atop your cookies and brownies.
Step 4: Spread and Bake
Carefully spread the blondie batter over the Oreo cookie layer, making sure to cover the cookies evenly and gently – you want to keep the layers distinct but blended in harmony. Slide your pan into the oven and bake for 35 to 40 minutes. You’re aiming for a toothpick inserted in the center to come out with just a few moist crumbs. Resist the urge to overbake, so the bars stay soft and chewy.
Step 5: Cool and Slice
Let the bars cool completely right in the pan to set properly. This cooling step is crucial to make sure the layers meld together and are easy to slice without crumbling. Once cooled, lift the whole batch out using the parchment paper and cut into about 16 bars to enjoy pure, blissful Oreo Brownie Blondie Bars Recipe perfection.
How to Serve Oreo Brownie Blondie Bars Recipe
Garnishes
These bars are irresistible on their own, but you can add a sprinkle of powdered sugar on top for a delicate touch. For a bit of decadence, drizzle some melted white or milk chocolate on each bar. A few crushed Oreos or a dollop of whipped cream also make fantastic, eye-catching garnishes.
Side Dishes
Serve your Oreo Brownie Blondie Bars with a scoop of vanilla ice cream or a drizzle of caramel sauce to bring out extra richness. Fresh berries or a small bowl of fruit salad help balance the sweetness with a refreshing contrast. A hot cup of coffee or milk also pairs perfectly for a cozy treat.
Creative Ways to Present
If you’re hosting, consider stacking the bars on a pretty cake stand or arranging them in a colorful dessert tray with other bite-sized desserts. Wrapping individual bars in parchment and tying with ribbon makes charming party favors, too. These bars are both beautiful and versatile, perfect for any occasion.
Make Ahead and Storage
Storing Leftovers
Leftover Oreo Brownie Blondie Bars keep wonderfully in an airtight container at room temperature for up to four days. This makes them a fantastic make-ahead dessert for busy weeks or gatherings.
Freezing
You can freeze the bars by wrapping individual pieces tightly in plastic wrap and placing them in a freezer-safe bag or container. Frozen, they stay delicious for up to three months. Thaw overnight in the fridge when you’re ready to enjoy.
Reheating
Warm leftover bars in the microwave for about 10 to 15 seconds to bring back that soft, gooey texture. Just be careful not to overheat, or the bars might dry out. Reheating makes them taste freshly baked all over again.
FAQs
Can I use homemade brownie batter instead of the mix?
Absolutely! Feel free to substitute your favorite homemade brownie batter for the boxed mix. Just make sure to prepare it to a similar thickness so it holds the layers well.
Is there a way to make these bars gluten-free?
Yes, you can use gluten-free brownie mix and substitute the all-purpose flour in the blondie layer with a gluten-free flour blend. Just check that other ingredients are gluten-free to keep the bars safe for those with sensitivities.
Can I add nuts to the blondie layer?
Definitely! Chopped walnuts or pecans add a nice crunch and pair beautifully with the flavors in the bars. Fold about half a cup into the blondie batter before spreading.
Why do the Oreos go in the middle instead of on top?
Placing Oreos in the middle lets them soften slightly and meld with both the brownie and blondie layers, creating an irresistible texture contrast that’s soft yet crunchy, giving the bars their signature cookies and cream experience.
How thick should the bars be cut?
Cutting them into 16 equal bars yields squares that are just right for snacking or serving at parties. They’re satisfying without being too overwhelming—though you can cut smaller if you want bite-sized treats.
