Halloween Candy Cookie Bars Ingredients
For the Batter

- Light Brown Sugar – Adds sweetness and a hint of caramel flavor, contributing to the chewy texture; dark brown sugar can be used for a deeper flavor.
- Large Egg + Egg Yolk – Enhances richness and helps with structural integrity; replace with a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water) for a vegan option.
- Vanilla Extract – Adds depth of flavor; use pure vanilla extract for the best results.
- Baking Powder – Helps the bars rise slightly; ensure it is fresh for effective leavening.

How to Make Halloween Candy Cookie Bars
-
Preheat the oven to 350°F (175°C) and line an 8 x 8-inch baking pan with parchment paper. This ensures your bars come out easily and have a nice, even bake!
-
Whisk together melted butter and light brown sugar in a large mixing bowl until combined. This mixture should appear smooth and glossy, allowing for a deliciously chewy texture.
-
Add the large egg, egg yolk, and vanilla extract, whisking until smooth. This enriches the batter, elevating the flavor to heavenly heights!
-
Fold in the all-purpose flour, baking powder, and salt until no flour streaks remain. Be gentle here to maintain the lightness of your batter.
-
Incorporate the chopped candy bars, taking care not to overmix. The joy of biting into mixed-up candy surprises is what will make your Halloween Candy Cookie Bars irresistible!
-
Spread the batter evenly in the prepared pan. Level it out with a spatula, making sure to cover the corners for even baking.
-
Bake for 25 to 30 minutes until the edges are golden brown; the center may look slightly underdone. The bars will continue to set as they cool, so don’t worry too much about a soft center!
-
Cool the bars completely in the pan on a wire rack before slicing into 16 pieces. Patience is key here; fully cooling ensures clean cuts and beautiful presentation!
Optional: Serve warm with a scoop of vanilla ice cream for an extra indulgent treat!
