Step‑by‑Step Instructions for Halloween Candy Cookie Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350℉ (or 180℃). This essential first step ensures your Halloween Candy Cookie Bars bake evenly and achieve that golden-brown perfection. As the oven heats up, gather your ingredients and equipment to streamline the process, making it an enjoyable experience.

Step 2: Prepare the Baking Pan
While the oven is warming, line a 9x13x2 baking pan with parchment paper, allowing some overhang for easy removal later. Lightly spray the parchment with nonstick spray to prevent any sticky mishaps. This preparation is vital for achieving clean, beautifully shaped cookie bars.

Step 3: Mix the Dry Ingredients
In a medium bowl, whisk together 2¼ cups of unbleached all-purpose flour, 1 teaspoon of baking soda, and ¾ teaspoon of kosher salt. This step not only combines the dry ingredients but also ensures that the baking soda and salt are evenly distributed throughout the flour, enhancing the flavor and texture of your Halloween Candy Cookie Bars.

Step 4: Cream the Sugars and Butter
In the bowl of a stand mixer, combine ¾ cup of room-temperature unsalted butter, ¾ cup of dark brown sugar, and ¾ cup of granulated sugar. Blend these ingredients on medium speed until the mixture becomes creamy and smooth, about 2–3 minutes. You’ll know you’re on the right track when the color lightens, indicating the sugars have incorporated well with the butter.

Step 5: Add Eggs and Vanilla
Add 2 large eggs to the butter and sugar mixture, one at a time, mixing well after each addition. Once both eggs are incorporated, pour in 1½ teaspoons of real vanilla extract and blend until fully combined. Remember to scrape down the sides of the bowl with a spatula to incorporate all ingredients evenly, creating a rich, flavorful base for your Halloween Candy Cookie Bars.

Step 6: Combine Wet and Dry Ingredients
With the mixer on low, gradually add half of the prepared flour mixture to the wet ingredients. Mix until just combined, then add the remaining flour mixture, mixing until fully incorporated. Scrape down the sides and bottom of the bowl to ensure no flour pockets remain, yielding a smooth dough perfect for your treats.

Step 7: Fold in the Candy
Using a rubber spatula, gently fold in ½ cup of Reese's Pieces, ½ cup of chocolate M&M's, and your leftover Halloween candy. This step allows the colorful candies to be evenly distributed throughout the dough, adding delightful surprises in every bite of your Halloween Candy Cookie Bars, creating an enticing visual and textural appeal.

Step 8: Transfer the Dough
Transfer the cookie dough into the prepared baking pan, spreading it evenly across the bottom. Use your lightly greased fingers or a piece of wax paper to press the dough down so it forms a smooth, even layer. It’s important to ensure the dough is packed tightly to help the bars hold their shape during baking and cooling.

Step 9: Bake the Cookie Bars
Place the pan in the preheated oven and bake for 18 to 20 minutes. Rotate the pan halfway through baking for even cooking. You’ll know they are done when the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs, promising a chewy texture in your Halloween Candy Cookie Bars.

Step 10: Prepare the Toppings
While the cookie bars are baking, unwrap and chop any additional leftover Halloween candy you’re using. This prep work not only saves time but also allows you to be ready to add sprinkles of sweetness right after the bars are out of the oven—ensuring that every bit of deliciousness is enjoyed.

Step 11: Add the Halloween Candy
As soon as the cookie bars come out of the oven, immediately press your chopped candies gently into the top while they are still soft. This step not only adds a decorative touch but ensures that the candies meld perfectly into the warm surface, making your Halloween Candy Cookie Bars irresistible.

Step 12: Cool and Slice
Allow the cookie bars to cool completely in the pan on a wire rack. This could take about 30 minutes, but patience is key! Once cooled, use the parchment overhang to lift the bars out of the pan, then slice into squares. These treats are now ready to be enjoyed, showcasing the fun and flavors of your Halloween Candy Cookie Bars!

Tips for the Best Halloween Candy Cookie Bars

• Measure Accurately: Use the right measuring tools for flour, sugar, and butter to avoid dense cookie bars. Proper measurements make all the difference in your Halloween Candy Cookie Bars!

• Room Temperature Butter: Ensure your unsalted butter is at room temperature for easy creaming with sugars. This helps create a fluffy texture, keeping your bars chewy and delightful.

• Don’t Overmix: Once you add the flour mixture, mix until just combined. Overmixing can lead to tough bars—nobody wants that when indulging in Halloween Candy Cookie Bars!

• Cool Completely: Allow your cookie bars to cool completely before slicing. This ensures clean edges and prevents them from falling apart, giving you the perfect squares to share.

• Creative Toppings: Feel free to mix and match your favorite leftover Halloween candy! The more colorful, the better—your cookie bars will reflect your family's tastes and creativity.

How to Store and Freeze Halloween Candy Cookie Bars

Fridge: If you want them to last a bit longer, place the bars in the fridge where they can stay fresh for up to a week. Just remember to use an airtight container to prevent them from drying out.

Freezer: For long-term storage, freeze the bars by wrapping them tightly in plastic wrap and then placing them in a freezer-safe bag. They can be frozen for up to 3 months; just thaw before serving for the best texture!

Reheating: Enjoy them warm by microwaving for 10-15 seconds. This will bring back their chewy goodness and melt the candies slightly for an irresistible treat!
