Step 1

Heat oven to 390 degrees (unless you are chilling your dough). In a large mixing bowl, cream together butter, brown sugar, and sugar for at least 4 minutes, scraping the sides of the bowl often.

Step 2

Add egg, egg yolk, and vanilla and mix for 1 minute longer. Stir in caramel.

Step 3

Fold in flour, baking powder, baking soda, and salt. If sprinkling sea salt flakes on the top of cookies, reduce salt to 1/2 teaspoon. If you have time, I suggest chilling the dough for at least 30 minutes. This reduces the spreading of the cookies. I suggest a 24-hour chill time, if you can wait.

Step 4

If possible, use a light-colored baking sheet. Roll cookies into light balls and place on parchment paper-lined baking sheet. Bake for 8-11 minutes or until lightly golden on the sides. Remove from the oven and let set up for several minutes.

Step 5

Drizzle caramel all over each cookie before serving. If so desired, sprinkle with sea salt flakes.
