Directions:

1. Prepare the Oven and Pan:
   Preheat your oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper.
2. Mix the Wet Ingredients:
   In a mixing bowl, combine the melted and cooled unsalted butter with brown sugar and white sugar. Mix until well combined.
3. Incorporate Eggs and Vanilla:
   Add the egg, egg yolk, and vanilla extract to the butter-sugar mixture. Mix until smooth and creamy.
4. Combine Dry Ingredients:
   In a separate bowl, sift together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
5. Fold in Additions:
   Gently fold in the white chocolate chips, ensuring they’re evenly distributed throughout the batter.
6. Prepare the Oreos:
   Arrange 16 Golden Oreos at the bottom of the prepared baking pan in a single layer.
7. Layering the Batter:
   Pour the blondie batter evenly over the Oreo layer in the pan, making sure to cover them entirely.
8. Bake to Perfection:
   Place the pan in the preheated oven and bake for 30-35 minutes or until the top turns golden brown, and a toothpick inserted in the center comes out clean or with a few moist crumbs.
9. Cool and Serve:
   Once baked, remove the pan from the oven and allow the blondies to cool completely in the pan on a wire rack.
10. Slice and Celebrate:
    When cooled, lift the blondies from the pan, slice them into squares, and get ready to enjoy these delightful Birthday Oreo Blondies!
