Dough
½ cup (1 stick) unsalted butter, softened
2/3 cup sugar
1 large egg, separated
2 tablespoons milk
1 teaspoon vanilla extract
1 cup all-purpose flour cup
Dutch-process unsweetened cocoa powder
¼ teaspoon salt
½ cup finely chopped hazelnuts (or other nuts)

Caramel Filling
10 (1 × ½-inch) plain caramels
2 tablespoons heavy cream

Chocolate Drizzle
3 ounces fine-quality semisweet or bittersweet chocolate (not unsweetened), finely chopped

In a large bowl, using an electric mixer, beat together the butter, sugar, egg yolk, milk, and vanilla
until well blended. In a separate bowl, sift together the flour, cocoa, and salt.

Add the flour mixture to the creamed mixture and beat on low speed until it forms a dough.
Wrap the dough in plastic wrap, and chill until firm, at least 30 minutes.

Preheat the oven to 350°F/180°C. Lightly grease the baking sheets. Lightly beat the egg white.

Roll scant tablespoonfuls of dough into balls and coat with egg white, letting the excess drip off,
then roll in the nuts to coat. Arrange the balls, as you coat them, 1½ inches apart on the prepared
baking sheets.  Press your thumb into the center of each ball to flatten, leaving an indentation.

Bake the cookies, in batches, in the middle of the oven until they have puffed slightly
but the centers are still soft, 10 to 12 minutes. Remove from oven and immediately press the
centers of cookies again (I use the handle end of a wooden spoon).

Transfer to wire racks to cool. Meanwhile, make the filling.
Heat the caramels and cream in a small saucepan over moderately low heat, stirring
occasionally, until melted and the mixture is smooth. Spoon about ½ teaspoon of the
caramel filling into the center of each cookie and cool completely.

One hour before serving, make the chocolate drizzle. Melt the chocolate in the microwave
or a double boiler, stirring until smooth. Cool to warm and pour into a heavy-duty sealable
plastic bag. Seal the bag and make a small snip in one corner to form a small hole.

Drizzle the chocolate over the cookies and let stand until set, about 30 minutes.
