These Loaded Cookie Bars are the ultimate dessert for anyone who loves soft, chewy cookies, creamy filling, and plenty of crushed cookies on top. The recipe can be made in two delicious versions: a rich Oreo Cookie Bar and an Oatmeal Cream Pie Cookie Bar. Both start with a soft cookie base, are layered with a creamy vanilla filling, and finished with extra cookies and a sweet white chocolate drizzle.
They are thick, chewy, rich, and packed with texture. The combination of soft cookie dough, crunchy cookie pieces, creamy filling, and melted white chocolate makes these bars completely irresistible.
Ingredients
For the Cookie Base
- 1 cup unsalted butter, softened
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
For the Oreo Version
- 18–20 Oreo cookies, roughly chopped
- 6–8 additional Oreo cookies for topping
- 1/2 cup white chocolate chips
- 1 teaspoon vegetable oil or coconut oil
For the Oatmeal Cream Pie Version
- 12–15 oatmeal cream pie cookies, roughly chopped
- 5–6 additional oatmeal cream pie cookies for topping
- 1/2 cup white chocolate chips
- 1 teaspoon vegetable oil or coconut oil
Creamy Filling
- 8 ounces cream cheese, softened
- 1/2 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- 2 tablespoons heavy cream or milk
- Pinch of salt
Instructions
Prepare the Pan
Preheat your oven to 350°F (175°C).
Line a 9-by-13-inch baking pan with parchment paper, leaving some paper hanging over the sides. This will make it much easier to remove the finished cookie bars from the pan.
Lightly grease the parchment paper with cooking spray or a little butter.
Make the Cookie Dough
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until light and creamy.
This usually takes about 2–3 minutes with an electric mixer.
Add the eggs one at a time, mixing well after each addition. Add the vanilla extract and continue mixing until everything is smooth.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture. Mix just until a soft cookie dough forms. Avoid overmixing because too much mixing can make the finished bars tough instead of soft and chewy.
Add the Cookies
For the Oreo version, roughly chop the Oreo cookies. You want a mixture of small pieces and slightly larger chunks so you can see the cookies throughout the bars.
Fold the chopped Oreos into the cookie dough.
For the oatmeal cream pie version, chop the oatmeal cream pie cookies into pieces and gently fold them into the dough.
Do not crush the cookies into fine crumbs. Larger pieces create delicious pockets of cookie and cream throughout the finished bars.
Bake the Cookie Base
Transfer the dough to the prepared baking pan.
Use a spatula or your hands to gently press the dough into an even layer.
Make sure the dough reaches the corners of the pan.
Place the pan in the preheated oven and bake for approximately 20–25 minutes.
The edges should look lightly golden while the center should still appear slightly soft.
Do not overbake the cookie base. It will continue cooking slightly as it cools, and keeping the center soft gives these bars their delicious chewy texture.
Remove the pan from the oven and allow the cookie base to cool completely before adding the filling.
Prepare the Creamy Filling
While the cookie base cools, prepare the filling.
Add the softened cream cheese and butter to a mixing bowl. Beat until completely smooth and creamy.
Gradually add the powdered sugar, mixing on low speed at first so it does not fly everywhere.
Add the vanilla extract, heavy cream, and a small pinch of salt.
Increase the mixer speed and beat for another 2–3 minutes until the filling becomes fluffy and smooth.
If the filling seems too thick, add another teaspoon of cream or milk. If it seems too soft, add a little more powdered sugar.
The filling should be thick enough to spread easily without running off the cookie base.
Assemble the Bars
Once the cookie base has completely cooled, spread the cream cheese filling evenly over the top.
Use an offset spatula or the back of a spoon to create a smooth layer.
For the Oreo version, roughly crush several additional Oreos and sprinkle them generously over the creamy layer.
For the oatmeal cream pie version, cut or crumble additional oatmeal cream pie cookies and arrange them over the filling.
You can use plenty of cookies for a more loaded appearance, just like the bars shown in the picture.
Add the White Chocolate Drizzle
Place the white chocolate chips in a microwave-safe bowl.
Microwave in 15–20 second intervals, stirring well between each interval, until completely melted and smooth.
Add about 1 teaspoon of vegetable oil or coconut oil to make the chocolate easier to drizzle.
Transfer the melted chocolate to a small piping bag or a plastic sandwich bag with the corner snipped off.
Drizzle the melted white chocolate generously over the tops of the cookie bars.
For an extra-decorative finish, drizzle it back and forth in several directions.
Add a few more cookie crumbs or pieces while the chocolate is still melted so they stick to the top.
Chill the Bars
Place the assembled cookie bars in the refrigerator for at least 1 hour.
Chilling allows the cream cheese layer to firm up and makes the bars much easier to cut.
For especially clean slices, chill them for 2 hours or even overnight.
When ready to serve, lift the entire dessert from the pan using the parchment paper.
Place it on a cutting board and use a sharp knife to cut it into squares or rectangles.
For clean cuts, wipe the knife with a warm, damp cloth between slices.
Oreo Version
The Oreo version is rich, chocolatey, and crunchy.
The soft vanilla cookie base is packed with chunks of Oreo cookies and covered with a creamy vanilla layer. More Oreos are added on top, followed by a generous white chocolate drizzle.
For an even stronger Oreo flavor, you can replace 1/4 cup of the flour with finely crushed Oreo crumbs.
You can also use different Oreo flavors to create variations. Chocolate, golden, mint, or peanut butter varieties can all give the bars a completely different taste.
Oatmeal Cream Pie Version
The oatmeal cream pie version has a softer, warmer flavor.
Chopped oatmeal cream pie cookies are folded into the cookie dough, creating little pockets of sweet oatmeal and creamy filling throughout the bars.
The creamy frosting on top pairs beautifully with the chewy oatmeal cookies.
For extra flavor, add 1/2 teaspoon of cinnamon and a pinch of nutmeg to the cookie dough. This gives the bars a delicious homemade oatmeal-cookie flavor.
Helpful Tips
Make sure the butter and cream cheese are softened before mixing. Room-temperature ingredients create a much smoother dough and filling.
Do not overbake the cookie base. Slightly underbaked centers are what give these bars their soft and chewy texture.
Allow the cookie base to cool completely before spreading on the cream cheese layer. If it is still warm, the filling can become soft and difficult to spread.
Chilling is also important. The bars become much easier to cut and serve once the filling has firmed up.
For an extra-loaded dessert, add mini chocolate chips, chopped nuts, cookie crumbs, caramel sauce, or additional melted chocolate.
Storage
Store the finished cookie bars in an airtight container in the refrigerator because of the cream cheese filling.
They are best enjoyed chilled or allowed to sit at room temperature for about 10 minutes before serving.
Properly refrigerated, they can be enjoyed for several days.
You can also freeze the finished bars. Place them in a freezer-safe container with parchment paper between layers. Thaw them in the refrigerator before serving.
Final Thoughts
