The cookie bar has a golden brown, crumbly texture with visible chunks of black and white sandwich cookies embedded inside and on top. The sandwich cookies inside show their white cream filling, while the top has broken pieces of the same cookies scattered over the surface. The background is a white marbled texture with a white cookie bar blurred in the back and a dark cloth draped to the side. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

½ cup salted butter, melted and slightly cooled
¾ cup brown sugar, packed
¼ cup granulated sugar
2 large eggs, at room temperature
2 teaspoons pure vanilla extract
1¼ cups all-purpose flour
¼ teaspoon baking powder
¾ cup white chocolate chips
15 Oreo cookies, roughly crushed

Instructions

Step 1: Preheat the oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper, leaving some overhang on the sides to make it easy to lift the blondies out later.
Step 2: In a large bowl, mix the melted salted butter with brown sugar and granulated sugar until smooth and glossy. This creates the base for a chewy texture.
Step 3: Add the eggs and vanilla extract to the sugar mixture, stirring until the batter is smooth, cohesive, and slightly thickened.
Step 4: In a separate bowl, combine the flour and baking powder, mixing briefly to distribute evenly.
Step 5: Gradually fold the dry ingredients into the wet batter with a spatula, mixing just until combined to keep the blondies tender.
Step 6: Gently fold in the white chocolate chips and crushed Oreo cookies, distributing them evenly without breaking up the pieces too much.
Step 7: Transfer the batter to the prepared pan, spreading it evenly into the corners without pressing down. Optionally, sprinkle a few extra Oreo pieces on top and press lightly.
Step 8: Bake for about 20 minutes, or until the edges are set and lightly golden while the center remains soft and slightly underdone for chewiness.
Step 9: Allow the blondies to cool completely in the pan so they can finish setting. Use the parchment paper to lift them out, then slice into squares and serve.

Tips & Variations

For an extra fudgy texture, slightly underbake the blondies and let them cool completely before slicing.
Try using dark chocolate chips instead of white chocolate for a richer contrast with the Oreos.
If you prefer smaller Oreo pieces, crush the cookies more finely before folding into the batter.
Adding a pinch of sea salt on top before baking can enhance the flavors beautifully.

Storage

Store the cooled blondies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. Reheat gently in the microwave for 10-15 seconds to restore softness.

FAQs

Can I use regular chocolate chips instead of white chocolate?

Yes, substitute with your favorite chocolate chips such as milk or dark chocolate for a different but delicious flavor profile.

How do I keep the blondies chewy and not cakey?

Be careful not to overmix the batter once you add the flour, and bake just until the edges are set but the center is still slightly soft. Cooling completely before slicing also helps maintain chewiness.
