• In the bowl of an electric mixer fitted with the paddle attachment, cream together butter and sugar. Beat until light and fluffy. Add in egg and beat until well incorporated, scraping down the bowl, if necessary. Add in vanilla. Beat until smooth. With mixer on low, add in salt and flour. Mix until completely incorporated and the dough is uniform. Pull dough together and shape it into a cylinder with a diameter of about 2 1/2 inches. Wrap in parchment paper and freeze for at least 25 minutes.
• Preheat oven to 350 degrees. Slice dough into 1/8 inch disks and place on baking sheets, about an inch apart. Once you have made 30 cookies, wrap up the cookie dough, freeze, and save for another time. Use a tiny circle shaped cookie cutter or a large round cake decorating tip to cut a hole in the center of each disk. Refrigerate for an additional 10 minutes. Bake for 8 minutes, or until crisp. Let cool completely.
• Add coconut into the caramel. Warm the caramel in the microwave for about 10 seconds if necessary. Take cooled cookies and gently dip them completely in the caramel. Place on a parchment paper-lined baking sheet. Freeze until set, about 5 minutes.
• Melt chocolate in a microwave-safe bowl in 30-second intervals, stirring well after each interval, until fully melted. Place the caramel-coated cookies in the chocolate and cover only the bottom of the cookie. Use a fork to pull them out of the chocolate and place them on a parchment-lined cookie sheet. Use the chocolate still on the fork to drizzle stripes over the top of the cookies. Refrigerate until set.

For the caramel

• In a heavy-bottomed saucepan with high sides, combine sugar, corn syrup, water, and salt. Whisk until combined, and set over medium-low heat. Swirl the pan every now and then to help distribute the heat. Use can use a pastry brush dipped in water to brush the sugar crystals down the sides of the saucepan. When the sugar dissolves completely, raise the heat to medium. When it comes to a boil, watch very carefully for the bubbles to become more viscous (this means that the water has evaporated and that it is ready to go through the candy stages). As it is bubbling away, you want it to turn a deep amber color. When it does, remove the heat and, working quickly, use the spoon to scoop up a small amount of the candy and drop it into the small glass of water. If the blob turns hard like a lollipop, then it is ready. If the blob is still soft, put the pan back on the heat. Keep testing until the candy is hard. Remove from heat.
• Whisk in butter, 6 tablespoons of cream, and vanilla (Careful here, as the mixture should bubble violently for about 10 seconds). If the caramel isn’t smooth right away, return the pan to low heat and whisk until smooth.
