Creating your Spider Infested Chocolate Chip Cookies is straightforward if you follow these steps:

1. Preheat Your Oven: Set your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. Mix Dry Ingredients: In a bowl, combine the flour, baking soda, and salt. Set aside.
3. Cream Butter and Sugars: In a separate large bowl, beat the softened butter with granulated sugar and brown sugar until creamy.
4. Add Eggs and Vanilla: Mix in the eggs and vanilla extract until well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, mixing until just combined.
6. Add Chocolate Chips: Fold in the semi-sweet chocolate chips, ensuring even distribution throughout the cookie dough.
7. Scoop the Dough: Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheets, spacing them about 2 inches apart.
8. Bake: Place the cookies in the preheated oven and bake for 10-12 minutes, or until the edges are golden and the center is set but still soft.
9. Cooling Time: Remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
10. Decorate: Once cooled, add edible spider decorations on top of each cookie for a spooky touch.

These steps will lead you to create a batch of delightful cookies that will captivate your guests.
