That sounds absolutely heavenly! Gooey Chocolate Chip Cookie Bars are the perfect blend of classic cookie flavour with the ease of a bar, guaranteed to be ultra-moist, thick, and packed with melty chocolate.
The key to achieving that signature gooey texture is using extra butter, brown sugar, and slightly underbaking them.

🛠️ Instructions
I. Preparation
- Preheat and Prepare: Preheat oven to $175^\circ\text{C}$ ($350^\circ\text{F}$). Line a $9 \times 13 \text{ inch}$ (approx. $23 \times 33 \text{ cm}$) baking pan with parchment paper, leaving an overhang on the sides for easy removal.
- Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
II. Making the Dough
- Melted Butter and Sugars: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until well combined (about 1 minute).
- Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Combine: Gradually add the dry ingredients to the wet ingredients, mixing on low speed (or with a wooden spoon) until just combined. Do not overmix.
- Chocolate Chips: Fold in most of the chocolate chips, reserving about $1/4$ cup for sprinkling on top.
III. Baking (The Gooey Secret)
- Spread: Press the cookie dough evenly into the prepared $9 \times 13$ inch pan. Sprinkle the reserved chocolate chips over the top.
- Bake: Bake for 25 to 30 minutes.
- The Gooey Tip: The bars are done when the edges are set and lightly golden brown, but the centre still looks slightly underbaked, soft, and moist. If you bake them until they are fully set, they will be cakey, not gooey.
- Cooling (Crucial Step!): Remove the pan from the oven and let the bars cool completely in the pan (this can take 2-3 hours). This allows the centre to finish setting into that perfect gooey texture without overbaking.
Once cooled, use the parchment paper overhang to lift the bars out of the pan and slice them into squares. Enjoy the gooey goodness!
