Preparing the Cookie Dough:
- Preheat the oven to 375°F (190°C).
Begin by preparing your baking pan. Use a 9″x13″ baking pan and spray it generously with non-stick cooking spray. This ensures your bars come out easily after baking.
- Cream the butter and sugars.
In a mixing bowl, add the softened butter, brown sugar, and white sugar. Using a hand mixer or a stand mixer, beat the ingredients together on medium-high speed until the mixture is light, fluffy, and fully combined.
- Add eggs and vanilla.
Beat in the eggs one at a time, mixing well after each addition. Once the eggs are incorporated, add the vanilla extract and mix until the dough comes together.
- Combine dry ingredients.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
- Stir in the chocolate chips.
Finally, fold in the chocolate chips by hand or using your mixer. The dough should be thick and slightly sticky.
- Bake the first layer.
Place half of the cookie dough into the prepared baking pan. Spread it out evenly to form the first layer. Bake in the preheated oven for 8-10 minutes or until it’s just set and lightly golden around the edges.
Making the Caramel Sauce:
- Prepare the caramel mixture.
While the dough is baking, prepare the caramel sauce. In a microwave-safe bowl, combine the unwrapped caramels and evaporated milk. Microwave the mixture on power level 5 for 1-2 minutes, stirring every 30 seconds, until the caramels are melted and fully combined with the milk.
- Add peanut butter.
Once the caramel is smooth, stir in the peanut butter until completely incorporated. This will create a creamy, nutty caramel sauce that will form the gooey middle layer of the bars.
Assembling the Bars:
- Layer the caramel sauce.
Once the first layer of cookie dough is baked, remove the pan from the oven. Carefully pour the prepared caramel sauce over the cookie layer, spreading it evenly with a spatula.
- Add the second layer of dough.
Drop the remaining dough by teaspoonfuls on top of the caramel layer. It doesn’t need to cover the caramel completely—some of the caramel and chocolate will peek through, creating pockets of gooey goodness.
- Bake the assembled bars.
Return the pan to the oven and bake for an additional 17-20 minutes, or until the cookie dough is golden brown and the caramel is bubbling. The edges of the dough should be firm, while the center remains soft and chewy.
Finishing Touches:
- Cool and slice.
Allow the bars to cool completely in the pan before slicing. This helps the caramel set and makes it easier to cut clean squares. Once cooled, use a sharp knife to cut the bars into squares.
