Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a bowl, whisk together the flour, baking soda, and salt. Set aside.

In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

Gradually add the dry ingredients to the wet mixture and mix until just combined.

Divide the dough into two bowls. In one bowl, add green food coloring and mix until you achieve your desired shade. In the other, add purple food coloring.

Fold in the chocolate chips into both colored doughs.

Using a tablespoon, scoop out portions of the green dough and place them on the baking sheet. Repeat with the purple dough, placing them close together.

Bake for 10-12 minutes or until the edges are golden brown. Remove from the oven and let them cool on the baking sheet for 10 minutes before transferring to a wire rack.

If desired, sprinkle with edible glitter for an extra spooky effect!
