Double Chocolate Chip Cookie Bars, Made Easy
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C).
Allowing the oven to fully heat before baking ensures even cooking and proper texture.
Step 2: Prepare Your Baking Pan
Line a 9×13-inch baking pan with parchment paper, leaving a slight overhang on the sides for easy removal.
Lightly grease the paper if desired.
Step 3: Mix the Wet Ingredients
In a large bowl, whisk together:
- Melted butter
- Brown sugar
- Granulated sugar
Mix until smooth.
Add the eggs and vanilla extract, then whisk until fully combined and slightly creamy.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together:
- All-purpose flour
- Cocoa powder
- Baking soda
- Salt
Mix thoroughly to evenly distribute the ingredients.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet ingredients.
Stir gently until no dry streaks remain.
Avoid overmixing, as this can make the bars dense instead of soft and chewy.
Step 6: Fold in the Chocolate Chips
Using a spatula, gently fold in the semi-sweet chocolate chips.
Reserve a handful to sprinkle over the top before baking for a bakery-style appearance.
Step 7: Bake
Spread the batter evenly into the prepared pan.
Bake for 25–30 minutes or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs.
Do not overbake, as the bars will continue to firm up while cooling.
Step 8: Cool and Cut
Allow the cookie bars to cool completely in the pan.
Use the parchment paper overhang to lift them out.
Cut into squares or rectangles and serve.
No-Store Runs Needed
Missing an ingredient? Here are some easy substitutions.
No Brown Sugar?
Use an equal amount of granulated sugar, though the bars may be slightly less chewy.
No Butter?
Replace with melted coconut oil for a slightly different flavor.
No Semi-Sweet Chocolate Chips?
Use dark chocolate chips, milk chocolate chips, or chopped chocolate bars.
No Vanilla Extract?
A small amount of almond extract can provide a unique flavor twist.
Problems & Prevention
Dry Cookie Bars
Overbaking is the most common cause. Remove the bars when the center is just set.
Bars Falling Apart
Allow them to cool completely before cutting.

Avoid overmixing once the flour is added.

Ask the Chef
