Cookie Dough
- 1/2 cup unsalted butter, softened
- 1/2 cup brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 tsp baking soda
- 1/4 tsp salt
Add-ins and Toppings
- 1/2 cup chocolate chips
- 1/2 cup Halloween M&Ms or candy-coated chocolates
- 1/4 cup candy eyeballs
- Optional: sprinkles or chopped candy bars
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper to ensure easy removal and clean-up.
- Cream Butter and Sugars: In a large mixing bowl, beat the softened unsalted butter, brown sugar, and granulated sugar together until the mixture is light, fluffy, and well combined. This creates a smooth base for your dough.
- Add Egg and Vanilla: Mix in the egg and vanilla extract until the mixture is smooth and homogenous, ensuring even flavor and moisture throughout the dough.
- Combine Dry Ingredients: Stir in the all-purpose flour, baking soda, and salt until just combined, being careful not to overmix to keep the bars tender.
- Fold in Candy and Chocolate: Gently fold in the chocolate chips and Halloween M&Ms or candy-coated chocolates, reserving a small handful of candies and candy eyeballs for topping later.
- Spread Dough in Pan: Evenly spread the cookie dough into the prepared 8×8-inch pan using a spatula. Press the reserved candies and candy eyeballs onto the top of the dough to create a fun, festive look.
- Bake: Bake in the preheated oven for 20–25 minutes or until the edges are golden brown and the center is set but still soft.
- Cool and Cut: Allow the cookie bars to cool completely in the pan on a wire rack before lifting out using the parchment paper. Cut into squares and serve.
Notes
- For soft cookie bars, avoid overbaking; remove from oven once center is set.
- You can substitute candy eyeballs with other fun Halloween-themed candies if you prefer.
- Use parchment paper or grease the pan well for easy removal of bars.
- Optional sprinkles or chopped candy bars can be added on top or folded into the dough for extra texture and flavor.
