Chocolate Chip Cookie Bars Ingredients
For the Base
• Unsalted Butter – Provides richness and moisture; can be substituted with margarine for a dairy-free option.
• Light/Dark Brown Sugar – Adds sweetness and chewiness due to its molasses content; coconut sugar can substitute for less refined sweetness.
• Table Salt – Enhances the flavor of the bars; sea salt can be used for a subtler taste.
• Large Eggs – Provides structure and moisture; use room temperature eggs for better mixing.
• Vanilla Extract – Adds aromatic flavor; almond extract can be used for a nutty profile.
• Baking Powder – Leavens the bars for a light texture.
• All-Purpose Flour – The main structure-building ingredient; a gluten-free blend works for gluten-free options.
For the Chocolate Delight
• Chocolate Chips – The star ingredient for sweetness and chocolate flavor; consider a mix of milk and dark chips for variety.
• Optional Butterscotch Flavor – Enhances sweetness; can be omitted if unavailable.
• Optional Espresso Powder – Intensifies the chocolate flavor; leave it out if you’re not a coffee fan.
These Chocolate Chip Cookie Bars are bound to become a family favorite, with their delightful chewiness and rich flavor!
Step‑by‑Step Instructions for Chewy Chocolate Chip Cookie Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While that’s heating up, generously grease a 9″ x 13″ baking pan with non-stick spray or butter, ensuring every corner is coated. This will help the Chewy Chocolate Chip Cookie Bars effortlessly lift out once baked.
Step 2: Melt and Mix
In a medium microwave-safe bowl, melt the unsalted butter in the microwave for about 30 to 40 seconds until fully liquid. Remove from the microwave and stir in both light and dark brown sugar, mixing until well combined and smooth. The mixture should be glossy and slightly warm, which will contribute to the ultimate chewiness of the bars.
Step 3: Incorporate the Eggs
Once your butter and sugar mixture has cooled slightly, add in the large eggs one at a time. Beat each egg in vigorously with a whisk or wooden spoon until the mixture is thick and creamy, which should take about 30 seconds for each egg. This step is crucial for creating the chewy texture in your chocolate chip cookie bars.
Step 4: Flavor Boost
Next, stir in the vanilla extract and any optional flavoring, such as butterscotch or espresso powder, to enhance the overall taste. Mix until evenly combined, ensuring the rich aromas fill your kitchen as you prepare to add the dry ingredients. The consistency should be smooth with a lovely shine.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking powder. Gradually fold this flour mixture into your wet ingredients, stirring gently until just combined. Be careful not to over-mix; you want to maintain the structure for your Chewy Chocolate Chip Cookie Bars without developing excess gluten.
Step 6: Add the Chocolate Chips
Once your batter is ready, fold in the chocolate chips or any other desired mix-ins, like nuts or dried fruits. Use a spatula to gently combine, ensuring that the chocolate chips are evenly distributed throughout the batter, tempting you with their gooey goodness in every bite.
Step 7: Spread and Smooth
Transfer the batter into the prepared pan, using your spatula to spread it evenly across the surface. Smooth the top to create a level layer, which ensures even baking. Tap the pan gently on the counter to eliminate any air bubbles and help the batter settle into all corners.
Step 8: Bake to Perfection
Place the pan in the preheated oven and bake for 30 to 32 minutes. You’ll know your Chewy Chocolate Chip Cookie Bars are done when the top is shiny and golden, and the edges are slightly pulling away from the sides of the pan. The center may appear slightly underbaked, which is perfect for a fudgy texture.
Step 9: Cool and Cut
Once baked, let the bars cool in the pan for about 10 to 15 minutes before gently pressing down the risen edges with a spatula. Allow them to cool completely at room temperature before transferring to a cutting board. Once cool, slice into squares and serve, reveling in the delightful texture of your fresh Chewy Chocolate Chip Cookie Bars.

Make Ahead Options
These Chewy Chocolate Chip Cookie Bars are perfect for busy home cooks looking to save time! You can prepare the batter up to 24 hours in advance; simply mix all ingredients and store the uncooked batter in an airtight container in the refrigerator. When you’re ready to bake, just spread the batter into your baking pan and follow the original baking instructions. Alternatively, you can bake the bars ahead and store them at room temperature for up to two days or in the refrigerator for up to 3 days. For the best quality, cover them tightly to prevent drying out. Enjoy these delightful bars, freshly baked and just as delicious, whenever your sweet tooth strikes!
