Ingredients
Scale
Wet Ingredients
- 1 cup unsalted butter, melted
- 1 1/2 cups light brown sugar, packed
- 1/2 cup granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
Dry Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
Add-ins
- 1 cup white chocolate chips
- 16 Oreo cookies, roughly chopped
- 1/2 cup semi-sweet chocolate chips (optional)
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper to ensure easy removal and cleanup.
- Mix Wet Ingredients: In a large bowl, whisk together the melted butter, light brown sugar, and granulated sugar until the mixture is smooth and glossy, indicating the sugars are well incorporated.
- Add Eggs and Vanilla: Add the room temperature eggs and vanilla extract to the sugar mixture and mix until completely combined and smooth.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to evenly distribute the leavening and seasoning.
- Mix Wet and Dry: Gradually fold the dry ingredients into the wet mixture using a spatula, mixing just until combined to avoid overworking the batter and ensure a tender texture.
- Add Chocolate Chips and Oreos: Stir in the white chocolate chips, then gently fold in the roughly chopped Oreo cookies and the optional semi-sweet chocolate chips to evenly distribute throughout the batter.
- Spread Batter: Transfer the thick batter into the prepared baking pan and smooth the top evenly with a spatula to ensure uniform baking.
- Bake: Bake in the preheated oven for 28 to 32 minutes, or until the edges turn golden brown and a toothpick inserted into the center comes out with a few moist crumbs for the best chewy texture.
- Cool and Serve: Allow the bars to cool completely in the pan on a wire rack before slicing into 16 squares for serving.
Notes
- Do not overbake to maintain soft and chewy texture in the bars.
- For extra texture and visual appeal, reserve a few Oreo pieces to press on top of the batter before baking.
- Store bars in an airtight container at room temperature for up to 4 days to keep them fresh.
- For longer freshness, refrigerate and bring to room temperature before serving.
