Ingredients You’ll Need
These bars use basic staples to create a rich flavor. The cornstarch is the secret to that tender, melt-in-your-mouth texture.
- 2 1/8 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1 teaspoon cornstarch
- 1/2 teaspoon salt
- 3/4 cup unsalted butter, melted and cooled to room temperature
- 1 cup light brown sugar, packed
- 1/2 cup granulated white sugar
- 1 large egg, room temperature
- 1 large egg yolk, room temperature
- 2 teaspoons pure vanilla extract
- 1 1/2 cups semi-sweet chocolate chips
Step-by-Step
- Preheat oven to 325°F (165°C). Grease a 9×13 inch baking pan or line with parchment paper, leaving an overhang on the sides for easy removal.
- In a medium bowl, whisk together the all-purpose flour, baking soda, cornstarch, and salt. Set aside.
- In a large bowl, whisk the melted and cooled butter with the brown sugar and granulated sugar until no lumps remain.
- Whisk in the egg, egg yolk, and vanilla extract until the mixture is smooth and slightly glossy.
- Using a rubber spatula, fold the dry ingredients into the wet ingredients until just combined. Do not overmix.
- Fold in 1 1/4 cups of the chocolate chips until evenly distributed.
- Transfer the dough to the prepared baking pan and press it into an even layer using a spatula or damp fingers.
- Sprinkle the remaining 1/4 cup of chocolate chips over the top, pressing them slightly into the dough.
- Bake for 23 to 27 minutes, or or until the edges are very lightly browned and the top appears set. The center should still look slightly soft; do not overbake.
- Place the pan on a wire rack and allow the bars to cool completely in the pan to room temperature before slicing into 24 squares.
Best Ways to Enjoy It
Serve these bars with a cold glass of milk. They are also amazing with vanilla ice cream. Pack them in lunchboxes for a sweet surprise. Your kids will love finding these in their bags.
You can also bring them to a neighborhood potluck. They are easy to grab and eat with hands. Set them on a pretty platter and watch them disappear. They are always the first dessert to go.
Storage & Reheating
Store your bars in an airtight container. They stay fresh at room temperature for five days. You can also freeze them for up to three months. Thaw them at room temperature before eating. They stay soft even after being frozen.
If you like them warm, use the microwave. Heat a single bar for ten seconds. This makes the chocolate chips nice and melty again. It tastes just like it came out of the oven.
Tips for Best Results
- Don’t skip the extra egg yolk for maximum chewiness.
- Avoid overbaking to keep the centers soft and fudgy.
- Use room temperature eggs for a perfectly smooth batter.
- Line your pan with parchment for very easy removal.
- For a holiday treat, add a pinch of sea salt.
- Upgrade the flavor by using high-quality chocolate chunks.
- Measure your flour carefully using the spoon and level method.
Ways to Switch It Up
- Use gluten-free 1-to-1 flour for a diet-friendly version.
- Swap semi-sweet chips for dark chocolate for a richer taste.
- Add half a cup of chopped walnuts for extra crunch.
- Try white chocolate chips for a fun, sweeter twist.
Common Questions
Can I make these ahead of time?
Yes, you can bake them a day early. They stay soft and chewy for several days. Just keep them covered tightly at room temperature.
Why use melted butter instead of softened?
Melted butter creates a denser and fudgier texture. Softened butter makes the bars more like a cake. This recipe focuses on that classic chewy cookie feel.
How do I know when they are done?
The edges will be a very light golden brown. The top will look set but the center stays soft. They will firm up as they cool in the pan.
I hope these bars bring a little sweetness to your week. They are a staple in my kitchen for a reason. Happy baking!
