Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- All-Purpose Flour: Essential for structure; use a spoon to scoop flour into your measuring cup for accuracy.
- Baking Powder: This is your secret weapon for fluffy cookie bars; fresh powder is key!
- Unsalted Butter: Use room temperature butter for easy mixing; it adds richness that enhances flavor.
- Granulated Sugar: Sweetness overload! Adjust according to your sweet tooth preferences.
- Brown Sugar: Adds moisture and depth; dark brown gives an even richer taste.
- Eggs: Helps bind everything together; make sure they are at room temperature.
- Vanilla Extract: Pure vanilla extract elevates flavors; skip imitation vanilla if you can.
- Chocolate Chips: Choose semi-sweet or milk chocolate based on your preference; feel free to mix in white chocolate too!
- Cinnamon: Just a dash adds warmth; use it sparingly so it doesn’t overwhelm the other flavors.
- Nuts (Optional): Walnuts or pecans can add crunch; toast them lightly for extra flavor!

Let’s Make it Together
Preheat and Prepare Your Pan: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with cooking spray or line it with parchment paper for easy removal later.
Cream Butter and Sugars: In a large bowl, cream together unsalted butter, granulated sugar, and brown sugar until fluffy. The mixture should be light in color and very creamy—think clouds of sugary happiness.
Add Eggs and Vanilla: Beat in eggs one at a time along with the vanilla extract. Ensure each egg is fully incorporated before adding the next—this helps create that luscious texture we crave.
Sift Dry Ingredients: In another bowl, sift together all-purpose flour, baking powder, cinnamon, and salt. This ensures an even distribution of ingredients—no one wants an accidental cinnamon bomb!
Combine Mixtures: Gradually add dry ingredients into the wet mixture while stirring gently until just combined. Folding helps keep those cookie bars soft—don’t overmix unless you want tough cookies!
Add Chocolate Chips: Fold in those glorious chocolate chips (and nuts if you’re using them) until evenly distributed throughout the batter. Your kitchen will start smelling heavenly at this point!
Bake Until Golden: Pour the batter into your prepared pan and spread it evenly. Bake in preheated oven for about 25-30 minutes or until golden brown. A toothpick inserted should come out clean but slightly moist.
Once cooled slightly, cut into squares or bars. Decorate with festive sprinkles if desired! Enjoy every spooky bite of these Halloween Cookie Bars while laughing over ghost stories with friends!
