Preheat oven to 375 degrees. Prepare a baking sheet with parchment paper. Cream together the butter and sugar. Add the eggs and mix together. Pour in the vanilla and blend until combined.

Pour the flour, baking soda, and salt in a medium bowl and mix until combined. Slowly add the flour mixture to the butter mixture. Mix until combined. Fold in the chocolate chips.

Drop dough onto prepared sheet and bake for 8-11 minutes or until lightly golden. Remove from the oven. Allow to cool on baking sheet for 5 minutes. Transfer the cookies to a wire rack and allow to cool completely.

Melt a handful or two chocolate chips on microwave and pour it into ziplock bag. Snip the corner and pipe little spiders on cookies.
