Ingredients for Lazy Chocolate Chip Cookie Bars
– 2 ½ cups (312 g) all-purpose flour
– 1 teaspoon baking soda
– ½ teaspoon kosher salt
– 1 cup (227 g) unsalted butter, melted and cooled (I love Kerrygold!)
– ¾ cup (150 g) granulated sugar
– ¾ cup (165 g) packed light brown sugar
– 2 large eggs, room temperature
– 1 teaspoon pure vanilla extract
– 2 cups (340 g) semisweet chocolate chips (Ghirardelli or Nestlé work great)
– Optional: ½ cup chopped pecans or walnuts for extra crunch
Directions for Lazy Chocolate Chip Cookie Bars
1. Preheat & Prep: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or foil, letting an overhang on two sides for easy removal—and lightly grease with cooking spray or butter to prevent sticking.
2. Whisk Dry Ingredients: In a large bowl, whisk together the flour, baking soda, and salt until evenly distributed. This data-backed step reduces clumps and ensures a tender crumb by avoiding pockets of unblended leavening agent.
3. Combine Butter & Sugars: Pour the melted, slightly cooled butter into the dry mix. Add both granulated and brown sugars, stirring with a spatula until you achieve a sandy, wet-textured dough—no electric mixer needed for this lazy approach.
4. Add Eggs & Vanilla: Crack in the eggs and drizzle the vanilla extract over the dough. Fold gently with a sturdy spoon or spatula until just combined—overmixing can toughen the bars, so stop when you no longer see dry streaks.
5. Fold in Chocolate Chips: Gently stir in the chocolate chips (and nuts, if using) until evenly dispersed. According to reader data, a 2:1 chip-to-dough ratio delivers maximum melty pockets in every bite.
6. Press Dough Evenly: Transfer the dough to your prepared pan. Using lightly oiled fingertips or an offset spatula, press it into an even layer covering every corner—this ensures uniform baking and bar thickness.
7. Bake to Perfection: Bake for 20–25 minutes, rotating the pan halfway. Look for golden edges and a slightly underbaked center (it will set as it cools). Use a toothpick inserted in the middle; you want a few moist crumbs attached.
8. Cool & Slice: Allow the bars to cool completely in the pan on a wire rack (or chill for 30 minutes for cleaner cuts). Lift them out using the parchment overhang, then slice into 16 bars with a sharp knife.
Servings & Timing
Makes 16 bars
15 minutes prep, 20–25 minutes baking, 30 minutes chilling—about 1 hour total
Variations
– White Chocolate Macadamia: swap semisweet chips for white chips and stir in ½ cup macadamia nuts.
– Peanut Butter Chocolate: replace half the chips with peanut butter chips and swirl in ¼ cup creamy peanut butter.
– Gluten-Free Twist: use a 1:1 gluten-free flour blend to make these bars celiac-friendly.
– Double Chocolate: whisk ¼ cup unsweetened cocoa powder into the dry mix and toss in dark chocolate chips.
– Fruity Burst: fold in 1 cup dried cherries or cranberries with the chocolate chips for a tart-sweet combo.
– Vegan Option: substitute eggs with flax eggs, use dairy-free butter, and vegan chocolate chips.
Storage & Reheating
Store these Cookie Bars in an airtight container at room temperature for up to 3 days. For longer storage, freeze bars in layers separated by parchment paper for up to 3 months. To thaw, move frozen bars to the fridge overnight or leave at room temperature for 1–2 hours. Reheat individual squares in the microwave for 10–15 seconds or warm briefly in a 300°F oven for that fresh-baked vibe.
FAQs
Q: Can I use salted butter instead of unsalted?
A: Yes—just skip adding extra salt, since salted butter contributes about ¼ teaspoon of salt per stick.
Q: Why are my bars dry or crumbly?
A: Overbaking is usually the culprit—start checking at 20 minutes and pull them when the center still jiggles slightly; it will finish cooking as it cools.
Q: Do I need to chill the dough?
A: No chilling required—this lazy recipe bakes perfectly straight from the bowl, saving you time and counter space.
Q: Can I halve the recipe for a smaller pan?
A: Absolutely—use an 8×8-inch pan and shave off about 5 minutes of bake time, watching closely for doneness.
Q: Why did my bars sink in the middle?
A: That often means underbaking or opening the oven too soon; be sure the oven is fully preheated and avoid sliding the rack in and out.
Q: How can I get extra gooey chocolate pockets?
A: Press a few extra chips onto the hot surface right after baking so they melt into those indulgent pools.
Q: Is there a gluten-free version?
A: Yes—swap in a cup-for-cup gluten-free flour blend like Bob’s Red Mill or King Arthur and follow the same steps.
Q: Can I prepare the dough in advance?
A: You can mix the dry and wet ingredients separately and assemble on bake day, or press the dough into the pan and refrigerate it for up to 24 hours before baking.
