Step‑by‑Step Instructions for Halloween Candy Cookie Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (180°C). While the oven warms up, prepare your 9x13x2 baking pan by lining it with parchment paper, ensuring it hangs over the edges for easy removal later, and lightly spray it with nonstick spray to prevent sticking.
Step 2: Combine Dry Ingredients
In a medium mixing bowl, whisk together the unbleached all-purpose flour, baking soda, and kosher salt. This dry mixture is crucial, as it creates the right texture in your Halloween Candy Cookie Bars. Once combined, set this bowl aside to focus on your wet ingredients.
Step 3: Cream the Butter and Sugars
In a stand mixer fitted with a paddle attachment, cream together the unsalted butter, dark brown sugar, and granulated sugar until the mixture is creamy and light in color, about 3-4 minutes. This step helps incorporate air into the mixture, providing a softer texture for your cookie bars.
Step 4: Add Eggs and Vanilla
Carefully add the eggs to the creamed butter-sugar mixture one at a time, mixing on medium speed between each addition until they are fully incorporated. Finally, add in the real vanilla extract. Scrape down the sides of the bowl to ensure everything is well mixed and ensure a rich flavor throughout your Halloween Candy Cookie Bars.
Step 5: Incorporate the Dry Ingredients
Now, gradually mix in half of the flour mixture, followed by the remaining flour until just combined. Be careful not to overmix at this stage; you want a thick dough that holds together well without any dry spots—this mixture will be the base of your delicious cookie bars.
Step 6: Fold in the Candies
Using a spatula, gently fold in the Reese’s Pieces and chocolate M&M’s. This step not only infuses your dough with decadent flavors but also adds a fun crunch! For a festive twist, you can also fold in any other leftover Halloween candy you would like to use.
Step 7: Press into the Baking Pan
Transfer the cookie dough into your prepared baking pan. Press the dough evenly into the bottom, ensuring a flat surface that will bake evenly. This step is essential to achieving those chewy cookie bars you love, so be sure to spread the dough into every corner of the pan.
Step 8: Bake to Perfection
Place the pan in the oven and bake for 18-20 minutes, rotating halfway for even baking. You’ll know the Halloween Candy Cookie Bars are done when the edges are lightly golden and the center appears set but slightly soft; they will firm up as they cool.
Step 9: Add Extra Candies
As soon as the cookie bars come out of the oven, press additional candies into the warm surface. This not only makes them visually appealing but also ensures that the candies stick perfectly. The heat will melt the bottom slightly, helping them adhere.
Step 10: Cool and Slice
Allow your Halloween Candy Cookie Bars to cool completely in the pan on a wire rack. Once cooled, use the parchment paper to lift them out and slice them into squares. This cooling process helps the bars set perfectly, ensuring they’re chewy and delicious for serving.

Expert Tips for Halloween Candy Cookie Bars
Easy Cleanup: Use nonstick spray on your fingers when pressing the dough to avoid sticky situations and keep your hands clean while making these Halloween Candy Cookie Bars.
Candies Placement: Press candies into the warm cookie bars immediately after baking to ensure they stick. If allowed to cool first, the candies won’t adhere as well.
Mixing Caution: When combining the dry and wet ingredients, take care not to overmix. This preserves the gooey center and chewy texture that makes your cookie bars irresistible.
Baking Time: Keep an eye on the baking time; every oven is different! A perfectly baked bar should be golden at the edges but still soft in the middle.
Storage Tips: Store leftover cookie bars in an airtight container at room temperature for up to a week or freeze them to enjoy later!

Room Temperature: Store your cookie bars in an airtight container at room temperature for up to 1 week to maintain their delightful chewiness and flavor.

Thawing: When ready to enjoy, simply thaw the Halloween Candy Cookie Bars at room temperature for a few hours before serving, allowing their flavors to return.
Reheating: If desired, briefly warm the bars in the microwave for 10-15 seconds to revive their soft texture, making them irresistible fresh from the oven!
