These spider drop cookies are made with a soft purple sugar cookie base topped with chocolate frosting, googly eyes, and candy melt spider legs for a fun and spooky Halloween cookie everyone will love.
In an electric mixer, mix butter and both sugars. Add vanilla and egg yolk. Add flour, cornstarch, baking powder, and salt. Add 5-6 drops of regal purple icing gel until it becomes a deep purple color.
Use a 1.5-tablespoon cookie scoop to add mounds of dough to a baking sheet lined with parchment paper or a silicone mat.
Place the baking sheet in the refrigerator to chill for 1 hour.
Preheat the oven to 400℉. Bake the cookies for 12-13 minutes until the tops are set. Let cool.
Frosting
Whip butter in an electric mixer with a whisk attachment for 2-3 minutes until creamy. Add vanilla, melted chocolate, and milk. Slowly add powdered sugar. Whip frosting for 2-3 minutes until fluffy.
In a microwave-safe bowl, melt almond bark or candy melts. Add it to an icing bag with a round #6 icing tip, or use a Ziploc bag and cut a small bit of the corner.
On a baking sheet lined with parchment paper, wax paper, or a silicone baking mat, draw spider legs shaped like 7s. Let them set for about 10 minutes until they harden. Carefully peel them off the paper.
To attach the legs, add a small dot of melted almond bark or candy melts to the frosting where each leg will go. Gently press the chocolate legs into the melted chocolate. Let the chocolate set completely before moving the cookies. I recommend assembling the cookies on a baking sheet and chilling them until the chocolate and frosting are firm. This will help keep the legs securely in place until serving.
