Preheat oven to 350 degrees.

Cream the sugars and butter together in the bowl of a mixer.

Add the egg and vanilla extract and continue to beat until it’s fluffy and smooth, scraping down the sides of the bowl as necessary.

Add the flour, corn starch and baking soda and mix on low just until the ingredients are incorporated.

Fold in the chocolate chips.

Drop the dough onto a lined cookie sheet by the tablespoon a couple inches apart.

Bake in the preheated oven for about 10 minutes, no longer.

Remove from the oven

Put on cooling rack for 3-5 mins

Use a toothpick to make "spider legs" with the melted chocolate chips while still hot, but cookie part is set.
