Chocolate Chip Cookie Bars
Description
The recipe starts with melted, cooled butter combined thoroughly with sugars to create a rich base. Eggs and vanilla add moisture and flavor. The dry ingredients—flour, cornstarch, baking powder, and salt—are whisked together separately then gradually folded in, maintaining a tender crumb aided by the cornstarch. Mixing chocolate chips into the batter introduces melty pockets of chocolate throughout.
Baked in a 9x9 inch pan lined with parchment or lightly greased, the bars develop golden edges after about 35 minutes at 350°F, with a slightly soft center when appropriately timed. Cooling before cutting prevents the bars from crumbling but serving them warm enhances their soft texture.
Variations include baking in a 9x13 pan, which results in thinner bars requiring shorter baking. Baking times can vary depending on pan material; a toothpick test is recommended. Bars store well in airtight containers for days and can be frozen for longer storage.
Ingredients
- 1 cup butter melted and then cooled for at least 5 minutes, unsalted
- 1 cup light brown sugar firmly packed
- ¾ cup granulated sugar
- 2 large egg room temperature preferred, + 1 large egg yolk
- 1 ½ teaspoons vanilla extract
- 2 ¼ cups all-purpose flour
- 2 teaspoons cornstarch (cornflour in the UK)
- ½ teaspoon baking powder
- 1 teaspoon salt
- 2 cups semisweet chocolate chips
Instructions
- Preheat oven to 350F (175C) and prepare a 9x9" (23x23cm) pan (see note) by lining with parchment paper (or lightly grease and flour).
- Combine melted (cooled) butter and sugars in a large bowl, stir well.
- Add eggs, egg yolk, and vanilla extract and stir until well-combined.
- In a separate, medium-sized bowl, whisk together flour, cornstarch, baking powder, and salt.
- Gradually stir dry ingredients into wet until completely combined. Stir in chocolate chips.
- Spread batter evenly into prepared pan. Bake on 350F (175C) for 35 minutes or until edges just begin to turn golden brown.
- Allow to cool before cutting and serving (don't cool too long, though -- these are amazing when served still slightly warm!)
Notes
- Use a toothpick to test for doneness as baking times vary with pan size and material.
- Storing in an airtight container at room temperature keeps bars fresh for up to 5 days.
- The bars also freeze well; thaw overnight before serving.
- Baking times are shorter in larger pans and longer for ceramic or glass pans.
