Equipment

Ingredients

1 1/2 cups (180 grams) all purpose flour *spooned and leveled
1 teaspoon baking powder
1/2 teaspoon salt
12 tablespoons (170 grams) unsalted butter melted slightly cooled
1 cup (213 grams) packed light brown sugar
1/2 cup (100 g) granulated sugar
2 large eggs room temperature
1 Tablespoon vanilla extract
24 Oreo cookies, crushed up

Instructions

Prepare the pan and pre-heat. Adjust oven rack to middle position; heat oven to 350° F (177°C). Line a 13 by 9-inch baking pan with foil, or parchment paper and spray lightly with non-stick cooking spray. Set aside. I like to leave an overhang so they can be easily lifted out once baked and cooled.
Combine the dry ingredients. Whisk flour, baking powder, and salt together in medium bowl; set aside.
Combine the wet ingredients. In a second mixing bowl, together the melted butter, granulated sugar, and brown sugar until evenly combined. Whisk in the eggs, and vanilla until evenly combined.
Combine the wet and dry ingredients. Add the dry ingredients to the wet ingredients and stir together with a wooden spoon or spatula. Be sure to not overmix. Stop whisking once the flour has just been incorporated.
Fold in Oreos. Using a rubber spatula, fold in 20 crushed Oreo cookies. Spread batter into prepared pan. Crush up remaining 4 cookies on top of the batter.
Bake and cool your bars. until top is shiny, cracked, and light golden brown, 22 to 25 minutes; do not overbake. The edges should be set, but the middle should be dry to touch but may still feel soft. The bars will continue to bake and set up as they cool. Cool on wire rack to room temperature. Remove bars from pan by lifting foil overhang and transfer to cutting board. Cut into 16 bars and serve.

Notes

Storage: You can also store these on your counter, covered in an airtight container for up to 3 days. You can also store these on your counter, covered in an airtight container for up to 3 days. Storing them at room temperature if best. Refrigerating these Oreo blondies can end up making them dry.
Freezing: You can also freeze these for up to 3 months. Just make sure to cool completely and store in an airtight container. Thaw overnight in the fridge, or at room temperature quickly.
Chocolate Chips: I thought these were sweet enough of their own, but yes you could add in up to 1 cup of chocolate chips. Semi-sweet, milk chocolate chips would be great. I also think white chocolate chips would be great!
Oreos:I used regular Oreo cookies for this recipe but I think double stuff or even the Oreo thins would work. You could also experiment with using a different flavor of Oreo cookies in this recipe for a new fun twist!
