- 1/4 cup all-purpose flour – Helps to bind the ingredients together and gives structure to the bars.
Recommended Tools

The Method for Gooey Peanut Butter Chocolate Chip Cookie Bars

Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your cookie bars bake evenly and come out perfectly golden.
Step 2: Prepare the Baking Pan
Grease your 9×13 inch baking pan with non-stick spray or line it with parchment paper for easy removal.
Step 3: Mix the Ingredients
In a large mixing bowl, combine the two rolls of refrigerated chocolate chip cookie dough, sweetened condensed milk, peanut butter, and all-purpose flour. Use your rubber spatula to mix until everything is well combined. The dough will be thick and somewhat sticky.
Step 4: Spread the Mixture
Pour the dough mixture into the prepared baking pan. Using the spatula, spread it evenly to cover the bottom of the pan.
Step 5: Bake
Place the pan in the preheated oven and bake for 25-30 minutes, or until the edges are lightly golden and the center is set but still slightly gooey.
Step 6: Cool and Cut
Once baked, remove the pan from the oven and let it cool in the pan for at least 10 minutes. Then, transfer to a wire rack to cool completely. Once cooled, cut into squares and enjoy!
