Instructions

Preheat the Oven: Set your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prepare it for baking.
Mix Wet Ingredients: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and fully combined.
Add Eggs and Vanilla: Beat in the eggs one at a time for even incorporation, then add the vanilla extract and mix until the mixture is well combined.
Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to ensure even distribution of the leavening agent and salt.
Combine Mixtures: Gradually add the dry ingredients into the wet ingredients, stirring gently until just combined to avoid overmixing.
Fold in Chocolate Chips and Oreos: Carefully fold in the semi-sweet chocolate chips and crushed Oreo cookies until evenly distributed throughout the batter.
Pour into Baking Dish: Spread the batter evenly into the prepared 9×13-inch baking dish, smoothing out the top for uniform baking.
Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean, indicating doneness.
Cool: Remove the dish from the oven and allow the bars to cool in the baking dish for 15-20 minutes to set before slicing.
Optional Topping: If desired, sprinkle additional crushed Oreos on top of the bars before serving for extra texture and flavor.

Notes

Be careful not to overmix the batter when combining dry and wet ingredients to keep the bars tender.
Using room temperature eggs helps to blend the batter smoothly.
For easy slicing, cool the bars completely or refrigerate for a short time.
Store bars in an airtight container at room temperature for up to 3 days or refrigerate to extend freshness.
You can substitute semi-sweet chocolate chips with milk or dark chocolate chips according to preference.
