Gooey Chocolate Chip Cookie Bars deliver the buttery flavor and chocolate pockets of a classic cookie in one easy 9×9-inch slab. The square-pan method creates lightly crisp edges and a deliberately soft center without portioning a tray of individual cookies. The recipe makes nine bars and records ten minutes of preparation plus twenty minutes of cooking for a thirty-minute total. Its instruction allows a 20-to-22-minute bake at 350°F, followed by complete cooling before the slab is lifted and divided. Careful mixing and an even layer preserve the gooey texture promised by the name.

Why the Order Matters
Line a 9×9-inch square dish with parchment or coat it with cooking spray, then preheat the oven to 350°F. In one bowl, combine one and one-half cups flour, half teaspoon baking soda, quarter teaspoon baking powder, and half teaspoon sea salt. In another bowl, use an electric mixer to combine half cup softened butter, half cup packed light brown sugar, and half cup granulated sugar. Add exactly one large egg and one and one-half teaspoons vanilla, mixing until uniform. Gradually add the dry mixture to the butter mixture and stop as soon as it is combined. Stir in one cup chocolate chips. Spread the thick batter evenly into the prepared pan. Bake 20 to 22 minutes until golden and cooked to the preferred crispness. Cool completely, remove from the pan, and cut nine pieces.

Critical Visual and Timing Cues
Softened butter should accept light pressure but should not look oily or melted. Mixing it with equal half-cup measures of brown and granulated sugar creates an even base before the single egg enters. Whisk both leaveners and sea salt through the flour so no concentrated pockets remain. Add dry ingredients slowly, scrape the bowl, and stop when the final flour streak disappears; continued beating encourages a cakier, tougher bar. Fold the full cup of chips through the dough so every future square receives chocolate. Press batter into the corners and level its thickness. At 20 to 22 minutes, the perimeter should be golden and set while the center can remain softer. It firms through carryover heat, so cool fully before lifting or the slab may bend and tear.
Serving and Storage
Use the cooled square shape as a guide and cut three rows by three columns for nine generous bars. Serve at room temperature for the intended gooey center, or warm an individual piece gently and pair it with the source's optional scoop of vanilla ice cream. The ice cream is a serving suggestion, not an ingredient in the bars. Store completely cooled pieces in an airtight container, placing parchment between layers if the chocolate remains soft. Avoid sealing a warm slab because trapped steam softens the golden edges. The uncut slab can be baked ahead, cooled, covered, and divided shortly before service to protect moisture. The formula contains wheat, dairy, egg, and chocolate; verify the chip package for additional allergens when serving guests.
Practical Kitchen Notes
Keep the two leaveners distinct: baking soda is half teaspoon, while baking powder is only quarter teaspoon. Sea salt is half teaspoon. Butter, granulated sugar, and packed light brown sugar are each one-half cup. Exactly one large egg and one and one-half teaspoons vanilla supply the remaining moisture. The chocolate-chip amount is one cup, described as half of a 12-ounce bag, and no extra topping quantity is recorded. Do not introduce cocoa, nuts, or milk. The official cook figure is twenty minutes even though the oven instruction gives a 20-to-22-minute window; use golden color and desired crispness to choose within that range. The nine-piece yield is explicit and should not be silently converted to sixteen smaller bars.
Details Worth Preserving
This recipe relies on restraint at two points: mix flour only until combined and bake only until the chosen golden endpoint. Both protect the central softness. Parchment overhang makes removal safer, but cooking spray is the recorded alternative. The accepted ingredient photograph shows exactly one egg and every measured component; the 2×2 process ends in nine countable bars. The original hero stays unchanged at its existing R2 key. The first repeated finished image is removed, and the last original finished image remains third in the editorial body. Responsive WebP copies preserve aspect ratio and orientation, skip any width larger than its original, and use direct asset URLs rather than Cloudflare Image Transformations.
