Equipment

9x13 Baking Pan

Ingredients

1 cup (2 sticks) butter melted & cooled
1 cup packed light brown sugar
¾ cup granulated sugar
2 large eggs
1 tablespoon pure vanilla extract
3 cups all-purpose flour
1 teaspoon baking soda
½ teaspoon sea salt
18 Oreo cookies roughly chopped
½ cup semi-sweet chocolate chips
½ cup white chocolate chips

Instructions

Preheat your oven to 350°F. Spray a 9x13-inch baking pan with nonstick spray; for easy removal I like to also line the pan with parchment paper (optional).
In a large mixing bowl using an electric hand mixer, or use the bowl of stand mixer with the paddle attachment, beat the melted butter, light brown sugar, and granulated sugar until smooth and well combined; about 1 to 2 minutes, until it looks light and fluffy.
1 cup (2 sticks) butter, 1 cup packed light brown sugar, ¾ cup granulated sugar
Add in the large eggs and vanilla extract, and beat just until combined.
2 large eggs, 1 tablespoon pure vanilla extract
In a separate small bowl, whisk together the all-purpose flour, baking soda, and salt. Add the dry ingredients into the larger bowl of wet ingredients. Mix on low speed just until combined and no flour streaks remain in the dough (scrape down the sides of the bowl as needed).
3 cups all-purpose flour, 1 teaspoon baking soda, ½ teaspoon sea salt
Gently stir in the chopped Oreo cookie pieces, semi-sweet chocolate, and white chocolate until evenly distributed through the dough.
18 Oreo cookies, ½ cup semi-sweet chocolate chips, ½ cup white chocolate chips
Spread the cookie dough evenly into the prepared pan, using a spatula or the back of a spoon to smooth out the top.
Bake for 25-30 minutes or until the edges of the bars are lightly golden brown and a toothpick inserted into the center comes out clean or with moist crumbs.
Remove the cookie bars from the oven and allow them to cool completely, about 30 minute to 1 hour, inside the pan before cutting into squares.

Notes

Avoid Overbaking : To keep the bars chewy and soft-baked, it's important to avoid overbaking them. I always suggest setting the timer for the minimum time and going from there. Watch closely towards the end of the cook time; the edges should be lightly golden brown, the center of the cookie bar should look set and cooked (not wet like raw dough), and a toothpick inserted into the center should come out clean without any raw dough on it. As the bars cool at room temperature, they will continue baking slightly more and will set and come together nicely.
Chocolate Chips : The recipe calls for semi-sweet chocolate chips and white chocolate chips. You can use chocolate chip morsels, or my preference is to use baking bars or chocolate bars, roughly chopped into chunks, and use those instead of the morsels. I think the chocolate baking bars taste better in the recipe. Another great idea is to chop up a cookies and cream chocolate bar (Lindt brand) into chunks and use that in place of the two kinds of chocolate chip morsels. Feel free to use milk chocolate or dark chocolate if you prefer that over semi-sweet chocolate.
Use Parchment Paper : Lining the pan with parchment paper helps the bars cook more evenly and avoids the bottom of the bars from browning. I spray the pan first and then line it with parchment paper; the cooking spray helps the paper adhere to the pan and not move.
Butter : I prefer using salted butter in this recipe. However, if you prefer unsalted butter or want to control the salt amount, then that is fine. Just use whichever butter you prefer baking with.
Melted & Cooled Butter : Place the unwrapped butter into a microwave-safe bowl. Microwave for about 40 to 50 seconds. You should end up with half melted butter and half soft chunks of butter. Remove from the microwave and stir with a fork until everything is melted and smooth. The butter is ready to use! Doing it this way helps the butter not be piping hot because you didn't melt it all the way.
